Ford Verve Sedan Concept, 2008

Ford Verve Sedan Concept, 2008

 
 

Ford Motor Company is revealing the Verve, a concept vehicle that makes clear the vision for the new small cars Ford soon will introduce in North America.
The Verve is bold and sophisticated - to help it clearly stand out from other small cars on the road. Ford is building on decades of small car leadership in Europe as it develops new small cars for North America to appeal to increasingly savvy customers who value technology, design and fuel efficiency.

Both four- and three-door Verve body styles are being unveiled at the North American International Auto Show in Detroit, as curtain-raisers to a new global family of small cars set to debut in Europe and Asia beginning later this year and in North America in 2010. The four-door is the basis for the production vehicle that will be sold in North America. The European three-door is being shown to test market reaction to the bodystyle - as a possible additional small car for the North American market.

The Verve concept has been developed with Ford's new global product development strategy that better leverages the company's global strengths. Globally, Ford is building on its European small-car expertise to stake a bigger claim in this critically important segment. Ford's celebrated small car lineup in Europe includes such top-sellers as the Ford Focus, Fiesta and Ka.

Those benefits include a bold, modern, design along with sophisticated electronics, premium materials, surprising functional space and a fuel-efficient 4-cylinder engine - all previously unseen in this segment.

Small Car Popularity Skyrockets in North America
Momentum in small-car sales is outpacing overall industry growth worldwide. Globally, small car sales have grown from 23 million units in 2002 to an estimated 38 million in 2012. That's nearly 45 percent of the total expected 85-million unit industry, a level never before achieved. In the U.S., sales of small cars likely will grow by 800,000, or 25 percent - to a record 3.4 million units by 2012.

In fact, small cars and crossovers are the only vehicles with projected near-term growth in the U.S.
As a group, Millennials embrace eco-friendliness, stay in constant touch using modern technology and demand best-in-class products from around the world. This group will grow from representing 19 percent of the driving public in 2004 to amassing 28 percent in 2010.

Every day, 11,000 Millennials in the U.S. come of driving age. When it's time to buy their first car, nearly half of this group shops the small-car segment.

Verve Redefines Small-Car Segment
The Verve concept demonstrates that largesse is no longer the price of admission for a delivering a premium driving experience.
The Verve concept is built off of a design architecture flexible enough to yield three distinctive vehicles that are each recognizably Ford. The flexible design architecture also allows Ford to adapt quickly to rapidly changing customer tastes and will help the company enter new markets utilizing regionally tailored products off of a common platform.

The North American Verve sedan, painted in Rouge Red, has been modified slightly from its European and Asian counterparts - most notably in its front fascia.
Designers created a bold, three-bar graphic with a Ford blue oval in the upper grille opening and downsized the lower, inverted trapezoidal grille. Two unique LED side markers flank the front fascia.
What carries through all three global concepts are Verve's sophisticated design language and its inspiration: A modern world of fashion and cosmetics, echoed in the Verve's rich colors and distinctive, high quality materials.

The hood sculpture is toned and athletic but not overtly muscular. This form language combines with the more pronounced, rearward-stretching headlamps to give the face of the Ford Verve concept a friendly, open and inviting personality. The prominent headlamps feature two projector beams and a light-emitting diode (LED) array.

From the side view, the concept looks energetic and purposeful. Its profile is emphasized by the pillarless side window shape and the upper contour that mirrors the body's curving upper contour line.

This extends rearward from the angular A-pillar to marry the sculpted, semi-high-mounted, LED tail lamps sculpted to become part of the fullness of the body shape. These elements blend cohesively together and support the vehicle's panoramic glass roof.

The 18-inch, 12-spoke, two-piece alloy wheel design lends even more drama to the car, punctuated with a subtle sidewall stripe that complements the rich body color.
Other accents on the vehicle include a discreet chrome bar in the door handles and similar use of brushed aluminum on the lower grille surround, the rear license plate surround and on the lower edge of the front fog lamps.

Technologically Inspired
Verve's unique architecture embraces key electronic systems such as navigation, a dynamic sound system and in-car phone controls. Aesthetically, the Verve interior follows the curves and contours of the instrument panel shape.

Functionally, the center stack design decouples traditional elements of the entertainment system - the screen, control elements and the electronics. Separating these features allowed designers to position controls for optimal ergonomic positioning in a design that resembles the logic of a mobile phone.
The center console includes a tray for a mobile phone or MP3 player as well as a large bin for a purse near the handbrake. The center stack is a unique combination of sculpture, colors, materials and jewelry-like brightwork.

The primary gauges - speedometer and tachometer - are uniquely framed by binocular-shaped, short tunnels of brightwork that complement the center stack and contrast the rich interior colors like a fashion accessory.
Ford Verve concept's steering wheel is another work of sculpture. Its center section, sculpted of soft-feel material and framed in brightwork, provides a rich tactile and visual centerpiece for the Ford oval.

Ford: European Small-Car Know-How
Driven by a new global product development system that leverages Ford's global strengths, Ford designers in Dunton, England, and Cologne, Germany, developed the common small-car platform based on the converging tastes of global consumers.
Ford maintains small-car leadership in Europe with vehicles set apart by their world-class driving dynamics and dynamic designs.

With more than five million vehicles produced in Europe since it was launched in 1998, the Ford Focus is one of the only vehicles in the world to be named "Car of the Year" both in Europe and in North America. It is Ford's perennial top seller in Europe and, in 2007, was Europe's top-selling car in its class.
The Ford Fiesta - which is smaller than the Focus - debuted in 1976, and it has sold more than 12 million units in Europe.

The iconic Ford Ka redefined the small city car sector in Europe with its eye-catching and enduring design and fun-to-drive character when it was introduced more than 11 years ago. Sales remain strong - with more than 1 million cars sold.
The European Ford Fusion - introduced in 2002 - increased its sales by approximately 19 percent in 2007 versus the previous year and remains in the European top three sellers in its segment.

Infiniti G37 Sedan, 2010

Infiniti G37 Sedan, 2010

 
 
A more dynamic look and revised interior, with state-of-the-art infotainment technology available, take the Infiniti G37 Sedan into a new decade with more presence and quality than ever. The 2010 version of Infiniti's lead-in sports model for Europe remains just as potent, poised and well equipped as before, but benefits from enhancements that bring it into line with other Infiniti models as well as responding to feedback from Infiniti owners.

The changes are subtle but effective - as one glance at the sharper new front-end styling reveals. More sculptural, more distinctive and more indicative of the 320 PS (316 bhp) under the bonnet of every Infiniti G37, the new look moves the Sedan visually closer to its sportier two-door cousin, the Infiniti G37 Coupé.

New front light clusters - still with bi-Xenon adaptive cornering headlights as standard - and a fresh-looking iteration of the familiar double-arch Infiniti grille are the main component changes, proving the rightness of the original design. A redesigned under-bumper section with recessed, wide-set foglights (previously the fogs were set into the main light clusters) gives the 2010 G37 Sedan a more purposeful edge to its already striking visual impact.

The rest of the Infiniti G37 Sedan's body is untouched. Which is good news for fans of its trademark long bonnet, raked-back A pillars and athletic stance that projects power and grace in equal measure.

Changes in the cabin are just as subtle but equally tailored to meeting owners' expectations. For instance, the Rosewood interior accents are now high gloss, the leather hues slightly lighter and there's the option of a new a new Wheat leather colour combined with a black dashboard and upper door trims. Reinforcing the Infiniti G37's impression of quality is a new aluminium trim design, reminiscent of Japanese calligraphy, along with a redesigned centre console based on that in the EX and FX crossovers. Improving both legibility and design cohesiveness, the gauges and LCD instrument display now use white as background colour.

For the first time, Infiniti's much-praised information and entertainment platform, Connectiviti, is available in the Sedan following on from its debut in the Infiniti G37 Convertible earlier in 2009.

Notable for its all-embracing functionality and user-friendliness, the HDD (hard disk drive) based system connects all manner of modern technology, from MP3 players to mobile phones, with seamless efficiency. Connectiviti+ takes things a stage further with a 30GB Music Box and innovative satellite navigation system which, among its long list of functions, can even access built-in Michelin's Red and Green Guides to take you to the door of a top restaurant or hotel.

Three new exterior colours are available for 2010 models: Smokey Quartz, Graphite Shadow and Vibrant Red. All are Scratch-shield paint, of course. Other features unique to the Infiniti G37 Sedan are its charismatic V6 with VVEL valve technology and its chassis options of rear-wheel drive, four-wheel drive and four-wheel steer for the most sporting S version.

Mazda 3, 2010

Mazda 3, 2010

 
 
 
 

The Exterior design - expressive and emotional styling
A distinctive new front fascia is formed by the 5-point grille and openings at the front corners. These design cues combine with the sculpted shape of the hood and the bold, expressive lines that connect the hood to the front pillars. All the lines seem to flow into the center just below the 5-point grille, which creates a stronger expression of power and dynamism. From the side, the front fender line smoothly morphs into the beltline, clearly identifying the vehicle as a Mazda and communicating dynamism. The line of the side sill curves up and seems to connect with the rear spoiler to emphasize the vehicle's compact size and express its agility. In order to make the surface more expressive, Mazda designers slightly elaborated the depth of the hood edge, front fenders and the three-dimensional shape of the protruding body sides, carefully crafting curves that subtly reflect changes in natural light.

The rear view boasts a sporty design with wide stance. The strongest features are the protruding shoulders and emphasized center-focus design. This concept was carried over from the first generation Mazda 3 and made bolder to represent expressiveness. All the lines of the rear view are designed to concentrate on the brand symbol in the center. The impressive C-pillar design was also inherited from the first-generation Mazda 3 and made more prominent. This was made possible by Mazda's expertise in stamping technology.

The Interior design : sophisticated, sporty, and high quality
The inside of Mazda 3 is a sporty yet highly refined cabin. The dashboard sweeps out from the center toward both sides with dynamic flair as though it is flexing powerful muscles. The large center display and controls are laid out around the driver to deliver just the right feeling of snugness. The angle of the center panel was adjusted after careful analysis of the driver's hand movement, producing a more stylish and dynamic design. A soft, wood grained surface with minimized parting lines on the top of the dashboard enhances the interior quality. The new interactive lighting control enhances the driver's connection with the vehicle.

The Powertrains for all driving experiences
The powertrains combine Mazda's typical Zoom-Zoom driving experience with excellent environmental performance to provide exhilarating driving. They transmit just the right amount of G force that perfectly matches the vehicle's actual acceleration. This provides the driver with a more refined experience of oneness with the car. The new engine line up has been tailored for European customers and now includes the newly developed MZR-CD 2.2-litre turbo diesel engine, carried over from the all-new Mazda 6, in addition to the MZR-1.6-litre and 2.0-litre gasoline engines and the MZ-CD 1.6-litre turbo diesel. It is a high-performance clean diesel engine with top class output, fuel economy and quietness. The MZR-CD 2.2-litre turbo diesel engine will be offered in two variants: a high power version with a maximum torque of 400 Nm/1,800-3,000 rpm and a maximum output of 136 kW (185 PS)/3500 rpm, and a standard power version with a maximum torque of 360 Nm/1,800-2,600 rpm and a maximum output of 110 kW (150 PS)/3500 rpm. Both versions have outstanding clean emissions performance, comply with the Euro Stage 5 regulations and feature a Mazda developed unique Diesel Particulate Filter (DPF) technology for more efficient regeneration. Fuel economy is also greatly improved by 7 to 10 percent compared to the MZR-CD 2.0-litre engine equipped in the existing model, attaining 5.4 l/100 km for the standard power version and 5.6 l/100 km for the high power version.

The MZR 2.0-litre petrol engine underfloor catalyst is the world's first vehicle catalyst to be constructed with single nanotechnology, which controls even finer materials structures than nanotechnology. It is used to embed individual particles of precious metals, which are less than 5 nanometers in diameter, into the catalyst base material. This new development enables Mazda to reduce the amount of expensive precious metals such as platinum and palladium by 70 to 90 percent without impairing catalyst performance. The catalyst is an important part of Mazda's efforts to reduce reliance on limited resources.

Power steering, suspension and brake systems
To deliver just the right balance between fuel economy, light steering-wheel operation and a feeling of stability, all configurations of the all-new Madza3 are equipped with the Electro-Hydraulic Power Assist Steering system (EHPAS) that has earned high acclaim on the first generation Mazda 3. The suspension is based on the first generation Mazda 3 system, and has been enhanced to ensure even nimbler response to steering wheel operation, and also to improve roll control and maintain a flatter ride by strengthening the suspension damping. In the brake system, the vacuum booster has been tuned and the feeling of initial brake application has been optimized. The overall result is outstanding response and reassuring linearity under all braking conditions.

The Highly rigid body
The basic development concept for the body shell of the all-new Mazda 3 was to improve the overall balance of the body's rigidity and ensure it firmly absorbs the reaction force of the dampers. To this end, particular attention went to reinforcing the area around the front and rear suspension mounts and the joint sections in each corner, which are subject to greater stress. Structural adhesive was used to strengthen the joints for the front and rear suspension towers, and spot welding was added to reinforce the joints of the door openings. The result is a substantial improvement in rigidity and body hysteresis (the degree of car body deformation due to repeated applications of torsional load).

Class-leading aerodynamics
The drag coefficient for the European specification 5-door hatchback and 4-door sedan are respectively 0.30 and 0.28, amongst of the bests in the segment. These measures helped the engineers attain top-class levels for wind noise reduction, high speed stability and fuel economy.

Cabin environment - sense of oneness between car and driver
Aboard the all-new Mazda 3 is a new Human Machine Interface that contributes to the sense of oneness between the car and driver. The cabin interior is designed to allow the driver to concentrate on driving and also appreciate the level of quality in both design and the materials used.

A sporty cockpit that improves functional beauty
The new "zone layout" approach focuses on improving visibility and more intuitive controls which provide "a sense of the car and driver as one" and "a reassuring sense of confidence that frees the driver to concentrate on driving." First, the Mazda 3 development team integrated the information display and positioned it towards the front in the optimal "zone." This placed the information necessary while driving where it can be seen with the least amount of eye movement. Next, the engineers placed all the controls and switches within a single "zone" closer to the driver's hands. Designing the cockpit with controls and information display in separate zones frees the driver to concentrate on driving.

The Multi information display (MID)
Based on the concept of the zone layout, Mazda developed the Multi Information Display (MID). It clearly shows information on all the equipment needed while driving, such as the trip computer, audio system and compact GPS system (optional), which can be operated easily by switches mounted on the steering wheel.

Seats that fit better, provide greater support and are more functional
The raised sides on the front of the seat cushions were made 20mm larger than on the first generation Mazda 3 to increase the leg support for a better fit. The seat backs were also extended by 35mm, which better supports the occupant's posture. Seat position adjustment controls were also evolved. The new power seat has a 3-position memory function. Upon approach to the car, the left-front seat automatically adjusts to the settings chosen by up to 3 different drivers by recognizing the code of the key fob. High-grade models feature standard sports seats.

Substantially reduced road and wind noise
Many improvements were made to structural rigidity and powertrain NVH performance to provide a quieter, more pleasant ride, including the reduction of high frequency booming noise sometimes heard when decelerating while further evolving a sporty engine note. Increasing the rigidity of components and joints also helped to deliver a quieter ride that rates among the class leaders. The sound pressure level of road noise was curtailed by 6 to 11 percent over the previous model, and wind noise was reduced by approximately 6 percent, to 59.0 dB at 100 km/h with a 5 m/s crosswind, placing the all-new Mazda 3 among the quietest in the class.

The Safety
Mazda focused on enhancing active safety equipment that supports the recognition and avoidance of hazards. Specifically, the cutting edge active safety technologies featured on the all-new Mazda 3 include ABS, Electronic Brake Force Distribution (EBD), Dynamic Stability Control (DSC) and Emergency Stop Signaling system(ESS) as standard equipments, and bi-xenon headlights with a pivoting adaptive front lighting system (option). New features include the Rear Vehicle Monitoring system (RVM), Tyre Pressure Monitoring System (TPMS) and Heated Wind Shield (option). The new model's passive safety systems are comprehensive and include Mazda proprietary highly-rigid and safe vehicle body technology, the Mazda Advanced Impact-energy Distribution and Absorption System, as well as front seat active headrests and a complement of six airbags, placing the all-new Mazda 3 at the level of the top marks in collision safety testing around the world.

Volkswagen Up Concept, 2007

Volkswagen Up Concept, 2007

 
 
 

There are cars that endure for all times. They are icons of their type, masterpieces of craftsmanship and technology; they put ideas into motion, make progress tangible and sometimes quite simply make everyday life better, more practical and enjoyable. Many of these cars carry the VW logo. "Bug, Beetle, New Beetle", "T1, Bulli, Samba bus, California", "Golf, GTI". Now Volkswagen is presenting - as a world premiere at the International Motor Show (IAA) in Frankfurt - a concept car that once again has the right stuff needed to move more than just one generation. It is a small, pure and high-spirited Volkswagen that pays tribute to its environment. The overall concept is marked by an innovative, clear, intuitive functionality. The name of the concept car: up! - a positive name that is a synonym for departure, activity, dynamics and the future. "For Volkswagen", says Dr. Ulrich Hackenberg, Board Member with Responsibility for Technical Development, "the response of IAA visitors will be a decisive test to determine whether the concept has the same kind of potential possessed by the Beetle at one time or by the Golf today."

Concept
The up! is a city specialist, a car for four persons and all languages, for the job, the university, the drive to the beach and the excursion outside the city gates. A small car that shows a lot of size, because it offers more space than any other car of similar length (3.45 meters) and width (1.63 meters). Its engine - conceivable here are all facets of technology that can be sensibly applied - will run in the rear. And that changes everything: Space, mood and design.Walter de Silva, Chief Designer of the Volkswagen group, sums it up like this: "The up! is not a car whose form will become obsolete within a very brief period of time. It shines in its cleverness and yet is made with loving care. And so the up! is a clear and strong statement for future Volkswagen design." Furthermore, the team of designers and engineers has envisioned the up! concept car as the first member of an entire model line; other facets are entirely conceivable.

Exterior design
The fact that the engine of the up! runs in the rear has a decisive inf luence on its exterior design. That is because the up! has no classic radiator grille. It forges links to the Beetle. This fact alone gives it a great deal of independence. Dominant design characteristics are the headlamps that take an inward and diagonal line, between them the horizontally arranged air vents, the VW logo (as one of the few details kept in chrome), the tailgate that extends far forward and the smooth bumper with a circumferential black stripe as a detail of the "happy face" that is typical of Volkswagen.

The powerful appearance of the up!, despite all of its compactness, is emphasized by a very wide track width (1.42 meters) relative to vehicle width. The wheels are flush with the sporty outboard wheel arches and side skirts. The radial design of the wheels and surfaces extending right up to the edge of the rim make the 18-inch wheels appear significantly larger than they actually are.

The wheels that are arranged far outboard in the bumper areas reduce body overhangs to a minimum. All of these features are part of an unmistakable side profile with a very long roof arch as well as clear and large surfaces. Giving shape to its style here are the large doors and the lateral window surfaces, which incline sharply upward at the height of the rear wheel arch and thereby help to form the very independent C-pillar design.

Interior design
Mounting the engine in the rear opened up entirely new interior concepts. Relative to its exterior size, the space offering is exceptionally forward-thinking. The same is true of its variability: Except for the driver's seat, all other seats can be folded and removed. Since they are designed as light shells, they can be quickly stowed in one of the cargo areas - besides the front trunk there is also one in the rear - to free up space. Afterwards, the entire passenger compartment length can be utilized as a storage area for especially bulky objects.

To achieve the high level of seating comfort that is usual at Volkswagen, besides their ergonomic design, in the case of the up! this level of comfort is also attained by a simple yet very effective trick: Similar to a self-inf lating air mattress, air can be sucked out of the seat surfaces via a valve. This means that the seats can be adjusted 1:1 to the body anatomies of the occupants who have just
taken a seat.

Intuitive controls
On its up! concept car, Volkswagen is presenting some completely new solutions when it comes to operator controls. Klaus Bischoff, Chief Designer for the Volkswagen Brand, comments on this: "Another reason the up! is so fascinating is because everything, every detail, was thought out anew. In the interior we have a touchscreen with new proximity sensor technology for controlling the navigation, radio, trip computer and climate control systems. It is operated absolutely intuitively. As a result, the most complicated functions can be controlled like child's play."

The up! has two central displays. In the cockpit, a 8-inch monitor shows the driver key information such as vehicle speed, fuel level and range, as well as momentary CO2 emissions.

Lexus IS250C, 2010

Lexus IS250C, 2010

 
 

The new Lexus IS250C.
The new model combines the award-winning design of the IS sports saloon with outstanding open-top engineering ingenuity.
The IS250C displays Lexus quality and attention to detail in every aspect of its construction and is designed to exceed customer expectations with its fusion of top-down driving pleasure and uncompromised dynamic performance.
It also boasts the fastest opening time for a three-part roof design, with its lightweight aluminium structure folding away in just 20 seconds.

The EXTERIOR DESIGN
The Lexus IS250C builds on the elegant proportions, sweeping, sculptural lines and contrasting convex and concave surfacing of the IS saloon range to combine the muscular appeal of a sports coupe with the stylish lines of a convertible.
Only the bonnet, headlamps, door handles and mirrors are shared with the IS saloon, all other body panels have been redesigned to ensure they harmonise perfectly with the three-part folding roof.

The INTERIOR DESIGN AND COMFORT
The Lexus IS250C offers the same high levels of luxury and practical innovation as the IS saloon, with a number of bespoke technical revisions designed to ensure the on-board comfort and entertainment systems operate effectively when the roof is down.
The instrument panel, surrounding elements and the steering wheel are the same as on the IS saloon, but the instrument binnacle in front of the driver has been extensively revised to ensure good visibility is maintained during top-down driving.
The climate control system has been configured for top-down motoring, with the addition of speed sensitive control, which automatically increases air flow when the roof is lowered and further increases it in line with vehicle speed.


The RIDE COMFORT
The Lexus IS250C uses the proven front double wishbone and multink rear suspension format from the IS saloon range to give sporting, agile performance. Significant chassis revisions promote greater ride comfort suitable for a convertible and ensure consistent dynamic performance in both coupe and convertible guise.
Extensive temperature, vibration and shaking tests were carried out to ensure the changes to the bodyshell and chassis maintain NVH characteristics almost identical to those of the IS saloon. Class-leading low wind noise levels are achieved with help from acoustic glass for the windscreen and painstaking design of the roof, door and window panel seals.

The SAFETY
The Lexus IS250C has been designed to achieve a five-star frontal impact rating in Euro NCAP crash testing, with world-class safety performance in both coupe and convertible configuration. Numerous changes in the body structure enhance collision strength, roll-over protection and torsional rigidity, minimising cowl shake and optimising chassis control.

For added protection when driving with the roof down, the Lexus IS250C is equipped with new-design larger side airbags that provide head protection in the event of a side impact. The bodyshell also features additional energy-absorbing side impact pads for both front and rear seat occupants.

Porsche 911 GT3 R Hybrid, 2011

Porsche 911 GT3 R Hybrid, 2011


 

Debut in Switzerland, the Porsche 911 GT3 R Hybrid will be tested in long-distance races around the Nürburgring, Germany. The highlight of this test programme will be the 24 Hours race around the 14-mile Nürburgring Nordschleife circuit on 15/16 May 2010. However, the focus is not on the Porsche 911 GT3 R Hybrid winning the race but rather serving as a spearhead for the technology and a 'racing laboratory' that will provide invaluable knowledge and insight on the subsequent use of hybrid technology in road-going Porsche sports cars.

110 years since Ferdinand Porsche - the company's founder - developed the world's first car with hybrid drive, the Lohner Porsche Semper Vivus, it is entirely appropriate that Porsche is once again employing this visionary drive concept in a production car-based GT racing programme.

The hybrid technology featured in the Porsche 911 GT3 R Hybrid has been developed especially for racing, and is set apart from conventional hybrid systems in its configuration and choice of components. Uniquely, an electrical front axle drive with two electric motors each developing 60 kW supplements the familiar 480 hp (353 kW) four-litre flat-six 'boxer' petrol engine at the rear of the Porsche 911 GT3 R Hybrid. Consequently, the Porsche 911 GT3 R Hybrid has four driven wheels, offering even greater traction and agility.
Porsche 911 GT3 R Hybrid

A further significant point is that instead of the usual batteries of a conventional hybrid-powered road car, this 911 features an electric flywheel power generator - mounted inside the cockpit beside the driver - that delivers energy to the electric motors on the front axle.

The flywheel generator itself is an electric motor - with its rotor capable of spinning at speeds of up to 40,000 rpm - and stores energy mechanically as rotation, or kinetic, energy. The flywheel generator is charged-up whenever the driver applies the brakes, with the two electric motors reversing their function on the front axle and acting themselves as generators.

The driver is able to call upon this extra energy from the charged flywheel generator at his command for competitive advantage, such as when accelerating out of a bend or overtaking. The flywheel generator is slowed down electromagnetically in the generator mode and able to supply up to 120 kW to the two electric motors at the front axle from its resource of kinetic energy. This additional power is available to the driver after each charge process for approximately 6 - 8 seconds.

Energy formerly converted into heat, and thus wasted, upon every application of the brakes is now converted highly efficiently into additional drive power.

Depending on racing conditions, hybrid drive is used in this case not only for extra power, but also to save fuel. This again increases the efficiency and, accordingly, the performance of the Porsche 911 GT3 R Hybrid, by reducing the weight of the fuel tank or making pit stops less frequent, for example.

Porsche Intelligent Performance

The Porsche 911 GT3 R Hybrid is a perfect example of the Porsche Intelligent Performance philosophy, a principle to be found in every Porsche and defined as more power on less fuel, more efficiency and lower CO2 emissions - on the race track and on the road. Already, customers can buy a Porsche 911 coupe with a six-cylinder 345 bhp engine which can return nearly 30mpg Combined and produces just 225 g/km CO2; a feat unrivalled in its performance class and just one example of the application of Porsche Intelligent Performance to maintain outstanding driving dynamics yet lower running costs and environmental impact.

Devising smart, individual engineering solutions to combine performance and efficiency with everyday usability is something for which Porsche is renowned, and is evident in such developments as lightweight body construction methods, Porsche Ceramic Composite Brakes (PCCB) and the Porsche Doppelkupplungsgetreibe (PDK) double-clutch gearbox.

Audi TT RS, 2010

Audi TT RS, 2010


The Audi TT RS has a turbocharged 2.5-liter engine with direct gasoline injection; it produces 250 kW (340 bhp) and 450 Nm (331.90 lb.-ft.) of torque. The blazing five-cylinder engine enables the Audi TT RS to perform extraordinary feats. In conjunction with quattro permanent all-wheel drive and a high-performance chassis, the engine makes the compact Audi TT RS a top-notch sports car - available as a coupé or roadster.

Sporty five-cylinder gasoline engines have a long legacy at Audi. The most famous is arguably the turbocharged 2.1-liter engine in the Audi quattro. The first version, which was launched in 1980, offered an impressive 147 kW (200 bhp). And the Audi Sport quattro from 1984, directly inspired by motorsport, delivered a whopping 225 kW (306 bhp). For 25 years, turbochargers and quattro have been a dynamic formula for success.

Audi has resumed using this recipe. Designed from scratch, the five-cylinder engine combines a turbocharger with FSI direct gasoline injection to elevate the Audi TT RS to a high-performance sports car. The TFSI delivers 250 kW (340 bhp) from a displacement of 2,480 cc (151.34 cu in): a specific output of 100.8 kW (137.1 bhp) per liter.

The power-to-weight ratio is also outstanding. In the case of the Coupé, which weighs in at a mere 1,450 kilograms (3,196.70 pounds), the power-to-weight ratio is just 4.3 kilograms per bhp. The Audi TT RS Roadster has a weight of 1,510 kilograms (3,328.98 pounds) and a power-to-weight ratio of 4.4 kilograms per bhp - thanks to its extremely lightweight and largely aluminum body constructed as per the Audi Space Frame principle.

The Audi TT RS Coupé rockets from 0 to 100 km/h (0 to 62.14 mph) in 4.6 seconds; the Audi TT RS Roadster needs just a tenth of a second longer. The limited top speed of 250 km/h (155.34 mph) is merely the official figure for both versions; as an option, Audi can increase it to 280 km/h (173.98 mph).

Compact and Lightweight: The Five-cylinder TFSI
The ultra-powerful five-cylinder engine is extremely fuel-efficient, requiring an average of just 9.2 liters/100 km [25.57 mpg] as regards the Coupé (Roadster: 9.5 l/100 km [24.76 mpg]). Switchable flaps in the intake manifold mix the incoming air in a calculated configuration. Injected at a pressure as high as 120 bar by the common-rail system, the gasoline swirls intensely in the combustion chamber - which in turn cools the walls. This subsequently facilitates a compression ratio of 10.0:1, which is very high for a turbocharged engine. Both of the adjustable camshafts, controlled via chains, also enhance charging efficiency with respect to the air-fuel mixture.

The large turbocharger generates up to 1.2 bar of boost pressure. The intercooler, fed air ideally by the lower segment of the single frame radiator grille, reduces the temperature of compressed air by over 80 percent at full load.

When an Audi TT RS driver pushes the standard Sport button on the center tunnel, a flap installed in the left exhaust tailpipe renders the exhaust noise even more robust and intense while boosting engine responsiveness. An optional Sport exhaust system is available with matt black tailpipe trims and sound flap.

For Purists: The Driveline
The Audi TT RS is the first classic sports car in the Audi RS family. Like the Audi RS4 and the Audi RS6, the Audi TT RS was developed by quattro GmbH as a pure, no-holds-barred driving machine. A new six-speed manual transmission conveys the engine's tremendous power, and permits easy and precise operation thanks to a specially designed shift lever boasting particularly short shift travel. The transmission's defining characteristics are a high efficiency ratio and a sportily narrow spread of the gear ratios.

The Audi TT RS features quattro permanent all-wheel drive as standard equipment. Its heart lies at the rear axle: an electronically controlled, hydraulic multi-plate clutch. If a situation calls for it, the clutch redirects a majority of the torque input from the front wheels to the rear wheels.

High-tech Excellence from Audi: Chassis and Body
The chassis of the Audi TT RS builds on the cutting-edge foundation of the base Audi TT design. The four-link rear suspension, which handles longitudinal and lateral forces separately, plays a crucial role. The electromechanical steering is highly efficient and the power steering adjusts to the vehicle's speed. With aluminum in the front and sheet steel in the back, the body's innovative mixture of materials results in a well-balanced axle-load distribution, excellent crash safety, and the outstanding rigidity which lays the cornerstone for the car's precise handling.

The Face of Power: The Exterior
At just 4.20 meters (13.78 feet) in length, the vigorously compact Audi TT RS hints at its explosive potential from the very first glimpse. The front spoiler tapers downward into a splitter, reminiscent of a racing car. The large and squared air inlets have diamond-shaped inserts. And the high-gloss black single frame grille with a frame in matt aluminum look and the TT RS badge bear the same styling. The xenon plus headlights with LED daytime running lights notify faraway drivers that an Audi TT RS is approaching.

The Interior and Equipment Packages
The dynamic exterior of the Audi TT RS is matched by the interior. The leather multifunction sports steering wheel has an especially thick rim, is flat-bottomed, and is covered with perforated leather. Integrated in the instrument panel, the driver information system can display boost pressure and oil temperature as well as a lap timer for chronicling feats at the racetrack. The door handles consist of two slim strips - typical of Audi RS models. An automatic climate-control system and the concert sound system are standard, as are an electrohydraulic soft top and an electric wind deflector for the Audi TT RS Roadster.

Audi S5 Cabriolet, 2010

Audi S5 Cabriolet, 2010


The engine in the Audi S5 Cabriolet is a newly developed, supercharged, three-liter V6. The pressure in the 3.0 TFSI is generated by a mechanical supercharger - with impressive results: The power output tops out at 245 kW (333 hp), the torque between 2,900 and 5,300 rpm remains constant at a generous 440 Nm (324.53 lb-ft). The powerful thrust and the spontaneous, aggressive response make for a fascinating driving experience. The Audi S5 Cabriolet is catapulted in 5.6 seconds from zero to 100 km/h (62.14 mph) and accelerates up to a preset top speed of 250 km/h (155.34 mph). Yet at 9.6 liters per 100 km (24.5 US mpg), its fuel efficiency is highly impressive (preliminary values).
Standard equipment of the Audi S5 Cabriolet includes the servotronic, the seven-speed S tronic and the quattro drive system package. The sport differential is optional. A sport suspension keeps the body close to the road. The 18-inch cast aluminum wheels are equipped with 245/40 tires. The black brake calipers are emblazoned with S5 emblems. The acoustic top, xenon plus headlights, electrically adjustable sport seats with Alcantara leather upholstery, and a multifunction sport steering wheel are also standard equipment.
Audi A5 Cabriolet
Dynamic and wonderful to look at, the new Audi A5 Cabriolet is a real Audi, and an especially exciting one at that. The four-seater with the fabric top combines a sporty character with the fascination of open-top driving, refined comfort, and great everyday utility. Seven powerful engines, an agile suspension and a wide range of high-end options make the new Audi model the most attractive mid-range convertible. The top-of-the-line model of Audi's new family of convertibles is the Audi S5 Cabriolet. The engine of the S5 Cabriolet is the newly developed, supercharged three-liter V6 with gasoline direct injection. Prices start at EUR 37,300 for the 1.8 TFSI with 118 kW (160 hp) and six-speed manual transmission. Delivery of the first Audi A5 Cabriolet models will begin in the second quarter of 2009.
Like all open-top Audi models, the new Audi A5 Cabriolet too has a classic fabric top - which endows it with a striking silhouette of dynamic elegance. The lightweight softtop opens in 15 seconds - and closes in 17 seconds. The fully automatic open/close drive comes as standard. An acoustic top is optionally available, which reduces wind noise almost to the hardtop level.

When opened, the Audi A5 Cabriolet top folds down so effectively that very little trunk space is used up - leaving 320 liters (11.3 cu ft) of unused storage volume, clearly the best value in its field of competitors. The softtop compartment lowers itself automatically when the top is opened.
Equally useful is the fold-down rear seat backrest with the large pass-through between the luggage space and the interior, which increases the storage volume to a generous 750 liters (26.49 cu. ft.).
Automatic seat belt extenders round out the comfort in the interior. Neck-level heating is optionally available for the front seats. The optional leather seats are coated with a special layer to reduce solar heating. There is comfortable room for four persons. The refined ambiance combines with exemplary ergonomics to convey an atmosphere of sporty elegance. Ultra-high-strength steels and selective reinforcements of the body ensure maximal rigidity and crash safety.

Fascinating dynamics: Audi drive select
The perfect addition to this technology package is the Audi drive select vehicle dynamics system, which enables the driver to chose among three different engine maps controlling the characteristics of the fuel feed, the shifting points of the seven-speed S tronic and multitronic, and the mode of operation of the servotronic steering system.

Audi drive select is only available in combination with one or more of three additional technologies - the sport differential, the adaptive control for the shock absorbers, and dynamic steering. This is an additional high-tech solution: Its superposition gear varies the gear ratio as a function of the driving speed by up to 100 percent.
The new Audi A5 Cabriolet features a rich array of equipment, including 17-inch alloy wheels, automatic air conditioning, and an audio system with a CD player. One of the highlights among the optional equipment is the third-generation MMI operating system, which provides many attractive navigation and entertainment functions.
As the dynamic top-of-the-line model of the new production series, the Audi S5 Cabriolet occupies a very special position. Its three-liter TFSI - a V6 with turbocharger - unfolds its 245 kW (333 hp) and 440 Nm (324.53 lb-ft) of torque impressively: It responds tenaciously to the throttle and delivers excellent driving performance. The quattro drive, a sport suspension with 18-inch wheels and a number of special equipment details underscore the athletic power of the Audi S5 Cabriolet.

The exterior design
The Audi A5 Cabriolet combines Audi's progressive styling with the fascination of an open-top car. The long engine hood, the sharp lines, the sweep of the shoulder contour, the elegantly curved surfaces, the large wheels, the distinctive front end, and the expressive tail all interact to create a sculptural, sensuous whole. The Audi A5 Cabriolet is 4.63 meters (15.19 ft) long and 1.85 meters (6.07 ft) wide, but only 1.38 meters (4.53 ft) tall: the sportiest proportions in its class.
The styling of the front end is dominated by the single-frame grille, which is flanked by large air intakes. The exquisite design of the headlights makes them look like technical jewels. The daytime running lights of the optional xenon plus headlights consist of LEDs. An aluminum molding lends high gloss to the windshield frame.
The looks of the tail end are sharpened by horizontal lines, broad tail lights, straight tailpipes, and a distinctly colored diffuser insert. The trunk lid bears an unobtrusive spoiler lip. The xenon plus headlight option comes complete with LED taillights, which create a distinctive light pattern.

The convertible top
The fabric top with the large glass rear window fits smoothly into the design profile. This is one of several reasons why Audi preferred it to a folding steel roof. What's more, its construction is much lighter in weight, which reduces the overall weight of the Cabriolet and lowers its center of gravity. The outer skin of the top is available in a choice of four colors, the inside in three.
The softtop consists of three layers. The intermediate layer is a cushioning pad. In the optional acoustic top, which reduces wind noise almost to hardtop level, this is replaced by a foam layer up to 15 millimeters (0.59 in) in thickness. The acoustic top comes with a ceiling light for the rear seat - a solution usually only found in the topmost convertible luxury segment.
In both versions, a hydraulic pump and four operating cylinders that move the top are actuated when a pushbutton on the central console or on the optional remote access assistant is depressed. It takes 15 seconds to open the top, 17 seconds to close it. Both actions can also be actuated while driving at up to 50 km/h (31.07 mph) - which makes driving much more comfortable.

When opened, the top is retracted underneath a fixed cover, where it is folded down into an extremely compact shape. Its storage compartment, which automatically lowers itself into the trunk space, only takes up a few centimeters in height - and only 60 liters (2.12 cu ft) of the 380 liters (13.42 cu ft) of luggage space. The remaining 320 liters (11.3 cu ft) with the top open are by far the best value among comparable vehicles. What's more, the low position of the loading lip makes loading and unloading easier. The wind deflector, which is supplied as standard, can be stored in the spare-wheel well to save space.
A very convenient feature in the Audi A5 Cabriolet are the split folding rear seat backrests. They can be easily unlocked by actuating levers in the trunk and drop automatically onto the seat cushions. The standard pass-though is 70 centimeters (27.56 in) wide. The loading space behind the front seatback is 1.76 meters (69.29 in) long, providing a total storage volume of 750 liters (26.49 cu ft).
