The new twin-turbo 5.5-litre V8, first revealed in March, has been conceived to replace AMG’s naturally aspirated 6.2-litre V8.The new engine will be offered in two states of tune. In standard guise, it kicks out 518bhp and 516lb ft of torque at 1750rpm. This gives the new CLS63 an additional 9bhp and 52lb ft over its predecessor.However, a performance package will lift those outputs to 549bhp and 590lb ft at 2000rpm. The heady reserves are channelled to the rear through AMG’s seven-speed MCT gearbox.Mercedes claims 0-62mph in 4.4sec in S (for Sport) and M (for Manual) modes — and 4.3sec with the optional performance package. Top speed remains limited to 155mph but an optional driver’s package can be ordered, which raises it to 186mph.
