We know the muscular engine power of the BMW M6 Gran Coupe, from the previous unveils. In Michigan, it is showcased at the famous Detroit Auto Show[NAIAS] 2013 with the all-new composition of 4-door coupe combined with the carbon fiber roof panel and best quality of material. While every component in the chassis and suspension of the new M6 Gran Coupe has given the base racing DNA nature of Sports Coupe. The 2014 M6 Gran Coupe has the engine which is developed over the proven experience on M V-8 Engine, which is highly tested and most powerful engine ever assembled on a M production car. The new M V-8 engine is twinPower Turbo 4.4-liter engine that generates a horsepower of 560[i.e. 412 kilo-Watts] at 5,750 – 7,000 RPM and produces a maximum torque of 500 lb-ft.[i.e. 680 Nm] from 1,500 to 5,750 RPM. The quick power generator and constant thrust of the M TwinPower Turbo V-8 is able to accelerate from 0– 60 mph in just 4.1 seconds with a top speed is electronically limited to 155 mph[i.e. 250 km/h]. he M Drive system in the new BMW Gran Coupe configures 6 parameters: the engine management, the response of the Servotronic steering system, the M-DCT shift program, the DSC mode, the responses of DDC and the information in the Head-Up Display. The M Drive configuration also includes the information shown on the optional M Head-Up Display and projects important information onto the windshield directly in the driver’s front. The new BMW M6 Coupe will come to the US Authorized BMW Center showrooms in early Summer of 2013. Its price tag, technical specification, fuel economy estimate with standard and optional features and equipment will be informed at the close time of its sale date.

Auto Press Release 2012 The style of BMW’s four-door Coupe with performance by BMW M Woodcliff Lake, NJ – December 12th, 2012… In early summer 2013, the all-new BMW M6 Gran Coupe will join its famous BMW M5 Sedan and M6 Coupe siblings as what is perhaps the perfect combination of both. The BMW M6 Gran Coupe is an ultra-high performance, four-door Coupe design with stunning aesthetics, race-bred technology, and the signature driving character of BMW M GmbH. The M6 Gran Coupe is made instantly unique among four-door vehicles by its bonded-in carbon fiber composite roof panel, similar to the one found on the M6 Coupe. Between the doors is a cabin of sensational coupe-like design and first-class materials. The M6 Gran Coupe’s control placement and – equally important – control feel are second to none. The four-plus-one seating arrangement allows the M6 Gran Coupe to carry four adults in luxury, and offers maximum seating capacity for five when needed. The new M6 Gran Coupe features the most powerful engine ever fitted to an M production car, a 4.4-liter M TwinPower Turbo V-8 with 560 horsepower and an always-accessible 500 lb-ft of torque. With this endowment, the rear-wheel drive BMW M6 Gran Coupe practically rockets from 0-60mph in 4.1 seconds and reaches an electronically-limited top speed of 155mph in only a few seconds more. The new BMW M6 Gran Coupe focuses the gargantuan muscle of its engine on the road through one of the most advanced drivetrains BMW has ever developed. The high-torque 7-speed M-Double Clutch Transmission (M-DCT) borrowed from the M5 and M6 Coupe sends power uninterrupted to the innovative Active M Differential, which in turn perfectly balances power between the rear wheels. This advanced drivetrain, combined with truly radical chassis and suspension revisions to the BMW 6 Series Gran Coupe on which the car is based, ensure that the M6 Gran Coupe’s substantial output is transferred to the ground predictably and repeatedly. The High-Revving M V-8 TwinPower Turbo Engine. The engine of the all-new M6 Gran Coupe has the highest output ever generated by a BMW M car, and provides a meaningful balance between ultra-high performance and fuel consumption. The engine’s operating behavior is characterized by traditional M traits like immediate throttle response and linear power delivery. Additionally, thanks to turbocharging, the engine features an unusually high and flat torque curve, sustaining peak torque from 1,500rpm – 5,750rpm. The engine produces about 10% more output than the M V10 engine which preceded it, and torque is up by over 30%. To achieve the performance levels of the new M V-8, the engineers at BMW M GmbH started with the proven BMW M-developed 4.4-liter V-8 engine from the BMW X5 M and X6 M (internally known as the S63B44 engine) and further developed it for its duty in the latest M5 and M6 models. Internally designated S63B44Tü, this engine uses similar M Twin Power technology combined with the reverse-flow V-8 layout. The result is that the high-revving V-8 engine lends a fresh intensity to the powerful M car experience. The S63Tü develops a peak output of 560 hp (412 kW) at 5,750 – 7,000 rpm (versus 555 hp at 6,000 rpm for the S63), while its maximum torque of 500 lb-ft (680 Nm) is on tap between 1,500 and 5,750 rpm (versus 500 lb-ft from 1,500 to 5650 rpm for the S63). The rev limiter intervenes at 7,200 rpm, up 200 rpm from the original S63 engine and now accessible in each gear until the top speed limiter intervenes. The rev band, which offers extreme acceleration between peak torque and the availability of maximum horsepower, is therefore almost three times as wide as that of the V10 engine from the previous generation of M engines. As in the M V-8 engine of the X5 M, the two twin-scroll turbochargers are placed (along with the catalytic converters) in the V-space between the two cylinder banks in a reverse-flow layout. This layout results in an unusually compact engine where the intake is moved outboard and the exhaust inboard – the opposite of traditional V-engines. The lengths of intake and exhaust tracts are thereby reduced and their diameters increased, reducing pressure losses – especially on the exhaust side. A further advantage of the layout is the short distance between the cylinders’ combustion chambers and the primary catalytic converters; this leads to quicker warm-up of the catalysts after the engine is started and therefore lower start-up emissions. The patented cross-bank exhaust manifold, first introduced in the S63 engine of the X5 M is also employed in the S63Tü, but with slightly larger tube sizes. This exhaust manifold is a special 8-into-4 setup that combines the exhaust from two cylinders (on opposite banks) that are 360˚ of crankshaft rotation apart from each other. Each of the eight runners is of identical length to ensure perfectly-regular timing of exhaust gas pulses. The acoustic sound of this engine arrangement is absolutely signature to BMW M. Each of the four manifold outlets is fed into each of the four available scrolls of the two twin-scroll turbochargers. The two scrolls of a twin-scroll turbo guide each exhaust pulse directly to the turbine without feedback or interference from the other scroll (that are fed by cylinders at other points in the combustion process). Additionally, dividing the gases into two smaller paths (scrolls) results in higher gas velocity than a single larger path. This enhances the turbocharger’s response, thereby reducing lag. The crossover manifold is configured so that the second scroll of the turbo is fed by two cylinders that are 180˚ out of phase with the first scroll. In this way each turbocharger receives distinct exhaust pulses every 180˚ of crankshaft rotation (from one of four cylinders). Furthermore, the two turbos receive exhaust pulses that are 90˚ offset from each other. The result is that throttle response is sharpened and turbo lag is reduced to a minimum. The new engine also sports larger intake runners, larger air to liquid intercoolers and a tuned exhaust which results in the engine making power more quickly than previously possible. Finally, the S63Tü uses a maximum boost pressure of 1.5 bar (21.7 psi) versus 1.2 bar (17.4 psi) for the original S63 engine. BMW’s efficient High Precision direct fuel injection also plays a major role in this engine’s combination of high performance and fuel efficiency. High Precision direct injection ensures an extremely precise supply of fuel to the combustion chambers. Injectors positioned centrally between the valves within immediate range of the spark plugs spray fuel into the combustion chambers with maximum pressure of 200 bar (nearly 3000 psi), providing smooth and clean combustion. Innovative solenoid valve injectors in the engine use multiple injections per combustion cycle to achieve an extremely precise mixture. The fuel also has a cooling effect on the combustion that allowed the M engineers to endow the engine with a high compression ratio of 10:1. This high compression ratio contributes to both performance and efficiency, while reducing exhaust emissions – and even has a positive effect on engine sound.
