Launching the new M6, BMW M GmbH is presenting the most sporting and dynamic rendition of the 6 Series Luxury Coupé. This makes the BMW M6 Coupé not only one of the most beautiful cars in the world, but also the most sophisticated and powerful 6 Series the world has ever seen: five litres capacity, 10 cylinders, 507 hp (373 kW) maximum output, 520 Newton-metres (383 lb-ft) peak torque and engine speed beyond the 8,000-rpm limit. Together with the excellent chassis and suspension designed without compromises for ultimate performance, this power unit boosts the BMW M6 right up to the highest ranks of supersports performance. But unlike its competitors in most cases offering only two seats, the M6 comes with all the space and comfort of a typical 2+2-seater as well as the luxurious features of a top-of-the-range BMW. The principle for success: sheer power in a discreet body. The M6 Coupé shares its outstanding power unit with the BMW M5 Sports Saloon acknowledged as the absolute benchmark in the high-performance saloon market. Offering the same standard of supreme performance, the M6 now sets the benchmark in the segment of high-power 2+2-seater luxury sports cars, the engineers at BMW M concentrating not only at the sheer power of the engine, but also on the weight of the body reduced to a minimum in the interest of even more dynamic performance and handling. As a result, the M6 is simply ideal also for the race track in terms of its dynamic performance, while in terms of motoring comfort, features and equipment it is equally ideal for virtually all roads the world over. And not least the elegant design of this very special BMW Coupé, featuring only discreet changes to the body, bears out all the understatement so characteristic of all M models as their fundamental feature. The customer benefits from the virtually inexhaustible power and performance of the ten-cylinder high-speed engine also through its interaction with the seven-speed SMG gearbox, the outstanding chassis and suspension, the elegant body in innovative lightweight technology, as well as the wide range of luxurious features all adding up to provide a new dimension in sports motoring.
It is indeed hard to find a genuine competitor able to face the BMW M6, since all other cars in this segment are either purist supersports or sports saloons much less agile in their handling and performance. Through its innovative drive concept, a power-to-weight ratio even better than on the M5, as well as unique handling - and all this with all the features and everyday driving qualities of a large coupé - the new M6 rightly comes in a class of its own, clearly reflecting the philosophy pursued by the engineers at BMW M GmbH. V10 power unit with racing-standard engine speeds. Featuring BMW's truly outstanding V10 power units, the BMW M5 and M6 come with one of the rare high-speed engines in a production saloon and coupé. Within the entire BMW brand, the V10 is the technically most demanding and most powerful engine concept of the highest standard. But power is not everything. Rather, what counts perhaps even more is acceleration and driving dynamics, two factors depending, first, on the weight of the vehicle and, second, on the power actually going to the drive wheels. This, in turn, is a function of engine torque and the overall transmission ratio. The high engine speed concept allows an optimum transmission and final drive ratio and, as a result, means impressive power and muscle on the drive wheels at all times. High-speed engine concept - the ideal solution. The compact, high-speed normal aspiration power unit is the ideal solution among all strategies in achieving maximum engine output: Revving up to a speed of 8,250 rpm, the V10 reigns supreme at engine speeds seen until recently only in fully-fledged racing cars. As a result, the engine exceeds the magical limit of 100 hp per litre, that is a level of specific output comparable to that of a racing car of the highest calibre. The two rows of five cylinders each making up the V10 are arranged at an angle of 90°, ensuring minimum vibrations and maximum comfort, with perfect mass balance of the crankdrive. Due to high loads resulting from combustion pressure, high engine speeds and vibrations, the crankcase is a so-called bedplate structure and the extremely stiff crankshaft runs in six bearings. Variable double-VANOS valve management ensures an optimum gas charge cycle for extremely fast valve timing. In practice this means more power, a better torque curve, optimum engine response, enhanced fuel economy, and exhaust emissions reduced to a minimum. Again reflecting the usual standard in motorsport, each cylinder comes with its own throttle butterfly with fully electronic control for each individual row of cylinders.
Twin-chamber stainless-steel exhaust system. Made of stainless steel without any connection joints or seams, the exhaust system runs all the way to the rear silencers as a twin-chamber configuration before exhaust gases leave the car through four tailpipes, like in all BMW M Cars. It almost goes without saying that exhaust emissions comply in full with both the European EU4 and the US LEV2 standard, the M6 standing out from the M5 also through its even more powerful, sporting sound. The outstanding power and emission control of the engine is attributable in particular to the sophisticated engine management system incorporating the most powerful processors currently to be found in the global car market, since the demands made of the processors are particularly great in this case due to the high speed of the engine and the wide range of management and control functions required. One of the highlights of the engine control unit is ionic current technology serving to detect any tendency of the engine to knock, any misfiring or mis-combustion. This system is able to detect any risk of the engine knocking via the spark plug in each cylinder, checking the correct ignition process and recognising any misfiring, thus coming as close as possible to the theoretical limits and ensuring optimum power and performance. The spark plug also serves as an actuator for the ignition and as a sensor observing the combustion process. Seven-speed SMG gearbox conveying M Power to the road. The concept of a high-speed power unit will work best if the engine is combined with an appropriate transmission that is with the right gear ratios. In that case the engine is able to convey the torque provided by the engine ideally into optimum power and performance through the short gear ratios. BMW's seven-speed SMG gearbox is exactly the right manual unit for ideally conveying the power of the V10 via the drivetrain to the rear wheels. This BMW M gearbox is indeed the only sequential transmission in the world with seven gears and a Drivelogic function. With even greater qualities than six-speed SMG transmission, this unique unit allows manual selection of gears with extremely short gearshift times as well as comfortable cruising thanks to automatic gear selection. And thanks to the additional gear, the "gaps" between engine speed and torque levels are even smaller than usual.
