Thanks to
leaked pictures we've already had a preview of the latest big AMG coupé, but now we have the official details of the new Mercedes-Benz CL 63 AMG.
As expected it uses the new bi-turbo, direct-injection, 5.5-litre V8 that was announced earlier this year. Thanks to sophisticated fuel injection, intelligent generator management and a start-stop function it promises to be cleaner and more economical than the outgoing model. As standard this engine develops 537bhp, though there is an optional AMG Performance Package that lifts power to 563bhp.
The power is transmitted through the AMG SPEEDSHIFT MCT seven-speed sports transmission. Rather than a conventional torque converter this uses a wet clutch for improved efficiency. In its most economical mode the transmission starts the car in second gear and shifts up as early as possible.
Claimed performance figures for the CL in standard form and with the Performance Package are 0-62mph in 4.5 and 4.4 seconds respectively; top speed is limited to either 155- or 186mph. The combined cycle fuel economy is 26.9mpg with CO
2 emissions of 244g/km.
Backing up the CL's straight line performance is variable-ratio Direct-Steer, which is intended to make the steering more responsive. The Electronic Stability Program boasts 'Torque Vectoring Brake', which briefly applies the brakes on the inner rear wheel to help the car around tight corners.
The new model can be identified by 'V8 Biturbo' lettering on the front wings. Inside, the steering wheel has been restyled with aluminium shift paddles and perforated Nappa leather grips. Customers can personalise their CL with a variety of AMG extras including carbon trim and double-spoke alloy wheels in place of the standard triple-spoke items.
The updated CL 63 AMG will go on sale in October.
