Powered by a new 421hp 5.5 litre naturally-aspirated V8 engine, the new Mercedes SLK 55 AMG will be priced at £54,950 on the road.
The retractable hardtop convertible will be able to reach 62mph in 4.6 seconds, with top speeds of 155mph.
Despite the increased power, fuel economy and CO2 emissions have been reduced by 30 percent, thanks to the introduction of AMG’s Cylinder Management System, similar to that on Mercedes-Benz’s Formula 1 engine.
Various customized options are also available including the AMG Performance Package of revised suspension and brakes with a rear differential lock (£4,105) and the AMG Driver’s Package, which raises the limited top speed and includes attendance at an AMG ‘Power and Passion’ driver event (£2,755).
First launched in 1996, the Mercedes-Benz SLK has gone through three generations so far: the R170 launched in 1996, the R171 in 2004 and the R172 in 2011.
