BMW 760Li, 2010
The new BMW 7-Series already sets the benchmark in luxury performance motoring - and now BMW is moving up the standard of maximum exclusivity and supremacy in this supreme class to an even higher level, following a completely new definition: The new BMW 760i and the new BMW 760Li are taking over the top position within BMW's model portfolio, representing the highest level of motoring refinement in their segment.
The heart and foundation of this exceptional new standard comes from the twelve-cylinder power unit featured in both top models in the BMW 7-Series. Developed as a completely new engine from the ground up, the V12 is a masterpiece of modern engine technology. Superior power of 400 kW/544 hp comes at an engine speed of 5,250 rpm, with maximum torque of 750 Newton-metres (553 lb-ft) from just 1,500 rpm.
Combined with the likewise brand-new eight-speed automatic transmission, this twelve-cylinder offers not only unparalleled motoring refinement, but also supreme driving dynamics through its ability to convert seemingly unlimited power reserves spontaneously and with precise control at all times into supreme driving dynamics.
The drivetrain with all its technical features is a masterpiece of supremacy in every respect. This applies both to the 6.0-litre all-aluminium power unit with TwinPower Turbo Technology, High Precision Injection with fuel injected directly into the combustion chambers, and to BMW's infinite double-VANOS camshaft adjustment as well as the eight-speed automatic transmission featured for the first time in a BMW.
Benefiting from all these technologies, the new BMW 760i and the BMW 760Li offer a new standard of motoring refinement, dynamic performance and all-round efficiency in a vehicle with this kind of power and output. Acceleration to 100 km/h comes in just 4.6) seconds, average fuel consumption in the EU test cycle is 12.9) litres/100 kilometres on the new BMW 760i.
In determining the cars' fuel consumption, BMW's engineers have already taken the stricter EU5 emission standard into account, meaning that with the cars' performance improving significantly fuel consumption is down by approximately 4.5 per cent versus the former model.
The Design: discreet signals on the outside, stylish exclusivity inside.
The outstanding looks of the BMW 760i and BMW 760Li benefit from the harmonious combination of elegance, sportiness and natural presence so characteristic of the new BMW 7-Series in its design. Offering 14 centimetres or 5.5" longer wheelbase, the extended version allows particularly comfortable access to the rear seats. And thanks to the unique design of the roofline and C-pillar contours, the side view of the car, despite the extra headroom for the rear-seat passengers, maintains the same overall impression as on the "regular" saloon with its "normal" wheelbase. Both body versions, incidentally, come with the longest wheelbase in their respective segments.
Inside the BMW 760i and the BMW 760Li the luxurious ambience is supplemented by various design features tailored specifically to these two models and matched in perfect harmony, again expressing the exclusive character of the V12 models. Stainless-steel door entry trim with an illuminated V12 cover, the instrument panel finished in nappa leather and surrounded by elegant seams, the roof lining and sun visors in alcantara as well as top-quality wood trim in exclusive burr walnut with individual inlays help to give the BMW 760i and the BMW 760Li a further stylish sign of distinction versus the other models in the BMW 7-Series.
The new V12 power unit: perfection as the underlying principle, innovation as the driving power.
The twelve-cylinder power unit in a BMW 7-Series Luxury Performance Saloon guarantees a driving and travel experience quite unique in every respect. No other engine offers such an outstanding combination of power and refinement, no other power unit provides the same supreme standard of prestige.
The new V12 power unit comes with 5,972 cc maintaining exactly the same cylinder volume as on the former engine. Displacing 497.7 cubic centimetres per cylinder, the engine therefore offers exactly the right size and dimensions acknowledged by engine specialists as absolutely ideal. Bore of 89 mm/3.50" and stroke of 80 mm/3.15" provides a ratio between these two parameters of 0.9, while the compression ratio is a remarkably high 10.0 : 1 quite unusual on a turbocharged power unit.
Introduction of TwinPower Turbo Technology on the twelve-cylinder.
BMW's new twelve-cylinder comes with a number of special technical features serving to capitalise on the potential it offers through its design principle and basic structure. In particular, this includes the first-ever use on a twelve-cylinder of TwinPower Turbo Technology and High Precision Injection with gasoline injected directly into the combustion chambers.
Featuring this combination of superior technologies already to be admired on BMW's six- and eight-cylinders, responding sensitively and directly even to small movements of the gas pedal, maintaining a consistent torque curve and offering a level of fuel economy and emission management quite unusual for an engine of this calibre, the new twelve-cylinder again stands out from the competition in every respect.
Thanks to the small cylinder angle of just 60°, the two exhaust gas turbochargers developed specifically for the new V12 fit in compact arrangement on the outside of the two rows of cylinders, each supplying six cylinders with compressed air.
Double-VANOS and volume flow-controlled oil pump for maximum efficiency.
Again in typical BMW style, the new twelve-cylinder comes with double-VANOS for infinite adjustment of camshaft control timing. This ensures part load running conditions with a high level of residual gas and reduced throttle loss for maximum fuel efficiency.
A further advantage of double-VANOS is its support in giving the engine a particularly direct response. Joined in a thermal process, the camshafts come with forged cams, additional triple cams on the intake side serving to drive the high-pressure fuel pumps. The valves on the exhaust side, in turn, are filled with sodium for optimum cooling and come with chrome-plated shafts.
The new twelve-cylinder models in the BMW 7-Series again feature a wide range of technologies for minimum fuel consumption and emissions based on BMW's strategy of EfficientDynamics. These include Brake Energy Regeneration, electric coolant pumps operating on demand, and the volume flow-controlled oil pump further optimising the balance of load performance and fuel consumption.
With an increase in engine output versus the former models by 22 and an increase in maximum torque by 25 per cent, the average fuel consumption determined in the EU test cycle has been reduced to 12.9) litres/100 kilometres. The emission rating of the BMW 760i is 299) grams per kilometre.
The engine coolant system on the new twelve-cylinder excels through consistent integration of all pipes in the crankcase, optimised cross-sections and the surface structure ensuring a maximum heat exchanger function helping to warm up the engine far more quickly than before on the former power unit.
The arrangement of the coolant inlet immediately next to the main inlet duct for supplying oil serves in addition to connect the two media in thermal terms, again helping to warm up engine oil and maintain the ideal temperature at all times.
The flow of coolant is separated on the two rows of cylinders, in each case running diagonally from the rear outside to the front inside. And last but not least, the arrangement of the outlets again helps to consistently spread out and maintain the temperature level over a wide range of engine speed.
The BMW's outstanding competence in twelve-cylinder technology: a long tradition of supreme performance.
This is the fourth time that a twelve-cylinder power unit marks the top end of the engine portfolio featured in the BMW 7-Series. And indeed, every new generation has further reinforced BMW's position as the leading manufacturer of luxury performance saloons. A BMW 7-Series with a twelve-cylinder power unit stands for exclusivity, supremacy and, not least, genuine innovation, the top-of-the-range engines providing the highest standard also on account of the maximum demands they are expected to meet right from the start in the development process.
World debut: eight-speed automatic transmission in the new BMW 760i and the new BMW 760Li.
The unique qualities of the new V12 power unit with TwinPower Turbo Technology and High Precision Injection are combined in the new BMW 760i and the new BMW 760Li with an equally innovative concept for the transmission of power: the newly developed eight-speed automatic transmission making its world debut in a BMW production car. Ideally tailored to the power and performance characteristics of the twelve-cylinder power unit, the eight-speed automatic transmission combines supreme gearshift comfort, sportiness and efficiency at a level never achieved before.
The new eight-speed automatic transmission excels through the innovative configuration of gears and gearsets allowing the use of additional gears and a larger range of gear increments than on the former six-speed automatic transmission, without any negative effects on the size of the transmission, its weight, and the inner efficiency of the system.
The eight forward gears and the reverse gear all incorporate four simple gearsets and five gearshift elements. The innovative arrangement of these components seen for the first time on an eight-speed automatic transmission ensures that only two clutches are open in each gear at any given point in time, significantly reducing frictional losses under all driving conditions to an absolute minimum.
Optimum gearset configuration as the result of scientific research.
To achieve significant progress over BMW's proven six-speed automatic transmissions, BMW's engineers right from the start initiated an in-depth development process providing the basis for the new transmission. The initial consideration was that particularly the improvement of efficiency as desired was only possible with a transmission system offering an even larger number of gears and a wider range of gear increments versus a six-speed automatic transmission. A further objective was to keep the number of additional components to a minimum in order to optimise the inner efficiency of the system.
