The body

The body  - Overview - Infiniti M

The M's design is signature Infiniti, its subtle curves and complex surfacing endowing it with an emotional draw that goes beyond the colder, more austere class norm. Its deeply sculpted door surfaces and front bumper section add distinction and a sense of both aggression and intrigue. The body crease below the glasshouse is the clearest of many design cues picked up from Essence, the stunning Infiniti concept car that made its debut at the Geneva Auto Show early in 2009.

To the benefit of both performance and efficiency, the Infiniti M is adept at carving through the air. Its drag coefficient is a mere 0.27 and the body has been designed for zero lift at the front and rear for increased high speed stability. As with other Infiniti models, the Infiniti M is equipped with lightweight aluminium doors, bonnet and boot lid (as well as an all-alloy V6 engine).

The Infiniti M uses the advanced FM (Front Mid-ship) platform that positions the engine behind the front axle resulting in an optimized front-to-rear weight balance for naturally stable and rewarding handling. Suspension is double-wishbone in front and multi-link at the rear, along with front and rear anti-roll bars. The standard wheel size is 18-inch. For the sportiest models, 20-inch wheels, new double-piston shock absorbers, special suspension settings, 4-piston brakes and 4-Wheel Active Steering are all available.

The Infiniti M37 is powered by the charismatic 3.7-litre VVEL V6 petrol engine also used in other Infiniti models in Europe. All alloy and of tried and trusted motor racing-style ladder-frame construction, power and torque are unchanged, at 320 PS (316 bhp) and 360 Nm (266 lb ft) of torque. Standard on every M is Infiniti's seven-speed Adaptive Shift Control (ASC) automatic transmission - complete with Downshift Rev Matching (DRM) and Drive Sport (DS) mode for full manual control via the available solid magnesium shift paddles behind the steering wheel. Performance data is yet to be confirmed.

Infiniti will release more information about the V6 diesel version during 2010.
