BMW has confirmed that the Michelin Pilot Super Sport will be its only fitment for its new high-performance M6 coupe and convertible models. The BMW M6 was launched to the market in the summer of 2012. It will exclusively feature the advanced Michelin Pilot Super Sport, which is the product of the unique merging of three technologies -- the Twaron-reinforced belt, the Bi-Compound tread band and the Variable Contact Patch 2.0.
The Twaron belt is a high-density fibre that’s mainly used in aeronautics and protective military gear as high strength is its key feature. Twaron® offers five times more resistance than steel at equivalent weight. It’s both light and strong. Because of its variable tension, the belt is tighter in the tread area compared to the shoulders.
The centrifugal force is more effectively controlled and pressure is more evenly distributed. Bi-Compound technology, which was developed for race tires initially, makes use of various rubber compounds on the left and right sides of the tread. Its outer shoulder uses an elastomer that guarantees outstanding endurance during cornering. Meanwhile, its interior has a different elastomer that works with a special tread design to allow the tire, on wet roads, to break through the water’s surface and adhere to the slightest road irregularities.
The Variable Contact Patch 2.0 could change its shape, depending on its actual driving conditions, therefore ensuring total vehicle control. The amount of rubber in contact with the road then stays the same because the patch’s shape will be changing even when cornering.
The use of these three technologies offers a drive that meets BMW M’s standards, especially when it comes to precise steering, handling and safety, on both road and track. The Michelin Pilot Super Sport provides high mileage potential, which is typical of this brand. This performance balance stands for the successful transmission of technology from track to street, as well as the close collaboration with the automaker, started many years ago for the BMW M5 project.
While both the Convertible and the Coupe versions of the M6 are expected to be able to display their own personalities, BMW added that there are also a number of distinct changes made to the style with some improvements done on the quality of the driving experience.
Even with these changes, what is sure is that the output which results into that excellent performance is due partly to the high-revving V8 engine that comes with the M TwinPower Turbo technology. The engine has been mounted to the front in a longitudinal manner and all of the power is transmitted to the wheels in the rear through the M Double Clutch seven-speed Transmission with Drivelogic.
In terms of actual figures, the 4.4-liter V8 engine is capable of 560 hp (412kW) which is available from 6,000 rpm and up 7,000, and can even go higher to 7,200 rpm. Maximum torque is 502 lb.-ft. (680 Nm) and already available from a low of 1,500 rpm up to a high at 5,750 rpm. It is clear that when combined to the engine inside the previous versions, the rev band offered in the new engine delivers maximum performance that is three time wider.
Aside from the exceptional M performance characteristics, it also has very fast responses. Then, as seen from the figures, there is that linear and strong power delivery that is ensured as higher rev range are attained. Even with the 10% increase in the output and the 30% increase in the top torque, the engine shows lower fuel consumption, as well as emissions, by at least 30%. What makes the powertrain perform the way it does is because it makes use of construction features that are based on motor sport and combined with the innovations that were made under the brand’s Efficient Dynamics.
Meanwhile, the package being included is truly one-of-a-kind with the VALVETRONIC variable valve timing, High Precision Direct Petrol Injection continuously variable Double-Vanos camshaft control, and the two turbochargers which follow the twin-scroll principle and even has a cross-bank exhaust manifold. To make sure the engine is performing as expected, the supply wet sump oil is optimized even when experiencing high lateral forces. Then there is the powerful cooling system.
