Attention all lovers of executive cars with obscene amounts of power, the latest Mercedes-Benz CLS 63 AMG has arrived. Complete with a subtle shape redesign and 7-speed transmission, the latest top-of-the-range offering from Stuttgart features a ferocious 547 bhp 5.5-litre V8 bi-turbo powerplant. Crikey.

You’ll be able to tell apart your AMG version of the CLS over a standard CLS by AMG ride control, sports suspension with an electronically controlled damping system and new front axle, newly developed electromechanical AMG sports parameter steering and also the optional AMG ceramic high-performance composite braking system.

Predictably proud of the car, Head of Mercedes-AMG Ola Källenius stated that ”The new CLS 63 AMG continues the success story of the previous models, the CLS 55 AMG and CLS 63 AMG, which have delighted our customers all around the world since 2004. The CLS 63 AMG is a unique high-performance car – it sets new standards in design, performance and efficiency.”

You’ll also be happy to hear that despite the boost in power over the previous AMG CLS, fuel consumption is actually reduced by 32% or a now combined 28.5 mpg in round figures, plus of course CO2 emissions have also dropped one third (113g/km) – the environmentalists will be dancing around the fuel stations of Affalterbach… On a quieter note, 0-62mph is now dispensed with in 4.3 seconds, which we’d probably best not mention at the same time as those impressive CO2 numbers.

We’ll let you decide which figure is of greater priority in any purchase decision, but one thing’s for certain, the new CLS 63 AMG has become an even more tempting proposition.
