Up front is a twin-turbo 5.5-litre V8 that develops 557PS. That’s enough to catapult two tonnes of car to 62mph in just 4.2 seconds and on to an electronically limited top speed of 155mph. If that’s not enough, then you can specify an ‘S’ model which ups the power by a further 28PS to 585PS. The AMG RIDE CONTROL sports car suspension features steel springs up front and a full air suspension system at the rear axle. An automatic double-declutching function for downshifting and the RACE START function are also featured. Little prepares you for quite how well all this technology hangs together. The E63 AMG feels properly well-sorted. It’s not one of those cars that shrinks around you, but so confidence-inspiring is the chassis that you don’t feel intimidated in driving this car hard and the torque makes mincemeat of hills or slower traffic. It’s utterly addictive. What’s more, unlike some of the Mercedes‘ rivals, you feel that the technology is working with you rather than serving to baffle or mask shortcomings. Here’s the new class benchmark.
