All-new BMW M6 makes world debut
It is a busy period in the BMW M division. Having just announced a new line-up of diesel-powered BMW M Performance Automobiles, the company takes the veils off the all-new BMW M6, launched in both Coupe and Convertible bodystyles.
Developed parallel with the M5, the all-new M6 naturally sits on the same platform and features many of the same elements that make Munich’s supersaloon tick. Under the hood is the same 4.4-litre bent-eight mated to a Getrag-sourced 7-speed dual clutch transmission – curiously stamped with a PowerShift label on its casing.
Equipped with two twin-scroll turbochargers and a lengthy list of other technologies, the M6’s S63 powerplant redlines at 7,200rpm and is quoted with the same figures as per the M5 – 560hp @ 6,000 – 7,000rpm and 680Nm @ 1,500 – 5,750rpm. Our experience with the M5 last year demonstrated this engine to be devastatingly capable, yet amazingly refined – a truly impressive piece of engineering.
The increased weight and reduced rigidity of convertibles mean that they will always be subject to dynamic disadvantages against their coupe siblings. While actual differences will only be discernible in a back-to-back review, numbers on the specs sheet suggest minor differences between the M6 Coupe and Convertible, which features a soft top, by the way.
In terms of kerb weight, 1,850kg of the Coupe plays 1,980kg of the ragtop. Though both are restricted to a 250kph top speed, the Coupe is marginally quicker in the century sprint – 4.2 versus 4.3 seconds – and consumes slightly less fuel – 9.9 versus 10.3 litres per 100km. Those willing to pay for the optional M Driver’s Package will have the speed cut removed, and both variants will max out at 305kph.
The essence of a BMW M car goes way beyond speed, which is already delivered in abundance. Equally of importance are the chassis enhancements that go to make these cars distinctly different from their run-of-the-mill brethren. The M6 is fitted with what BMW calls the Active M Differential which varies torque split between the left and right rear wheels based on available traction.
Suspension is based on the standard 6 Series, featuring double wishbones up front, and an integral multi-link behind. Components are forged from aluminium to reduce unsprung weight, and the setup is mated with electronically controlled dampers – standard equipment for the M6. As per the M5, the M6 is also resisting the switch to electric power steering, with BMW M remaining faithful to a hydraulic setup for now.
In addition to performance-oriented enhancements, the M6 is also comprehensively equipped with the now-mandatory array of EfficientDynamics fuel-sipping tech. Press materials make substantial references to weight saving measures such as aluminium doors and bonnet, thermoplastic front panels, and the Coupe’s carbon fibre roof.
