The new CLS 63 AMG is a case in point. It receives a bespoke engine and transmission, a new front axle, substantially modified suspension and steering systems as well a unique damping system.
The extensive styling changes inside and out are literally the icing on a seriously re-engineered cake. And AMG engineers have put over one million test kilometres into both the engine and the finished car.
It gets the company’s new M157 5.5-litre bi-turbo V8 engine which replaces AMG’s old 6.3-litre naturally-aspirated V8. The M157 (like all AMG motors, assembled by a single engineer) is more powerful, torquier and an amazing 32 per cent more economical than the outgoing engine. AMG has also developed its own ‘Speedshift MCT’ 7-speed transmission, which ditches a conventional - and laggy - torque convertor for a much more direct-feeling ‘wet start-up clutch’ which runs in a oil bath.
One of the most important aspects of the CLS’s development lies in the huge efforts that the company has put into the new electromechanical steering system. The 14:1 ratio is 22 percent quicker than the standard CLS, its is said to be extremely rigidly mounted and its control unit takes information from a wide range of sensors (including lateral acceleration and under and oversteer characteristics) to calculate the forces it feeds back to the wheel rim.
We also have the C63 Amg for hire a Premiere Velocity, it has exactly the same engine and the same noise!
