BMW M6 Gran Coupe - Full In-depth Interior and Exterior Walkaround Tour.

In early summer 2013, the all-new BMW M6 Gran Coupe joined 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.
