New Mercedes CL63 AMG
Mercedes has officially revealed the new CL63 AMG – complete with an all-new 536bhp V8 engine. The twin-turbo 5.5-litre lump replaces the naturally-aspirated 518bhp 6.2-litre V8 found in the previous model, and is now mated to a new seven-speed multi-clutch transmission. Despite weighing two tonnes, the improved powertrain pushes the CL63 AMG to 62mph in 4.5secs and won't stop accelerating until it hits the limiter at 155mph. Apparently that kind of performance won't be sufficient for every Mercedes customer so there's also an optional AMG Performance package available for the car. This increases power to 563bhp and boosts the CL63's torque output from 589lb ft to 633lb ft. This makes the coupe marginally quicker to 62mph, but also means the car will be capable of 186mph. Mercedes insists the range topper is not all about power though – the new engine is 7mpg more economical than the previous model at 26mpg and CO2 emissions are down to 244g/km. ...
