Mercedes-Benz has lifted the veil on a new, more powerful CL63 AMG, less than a month after revealing a raft of changes to standard versions of its range topping coupe.
Set to go on sale in the UK later this year, the up-market performance coupe receives a series of mid-life styling tweaks, including larger headlamps, a restyled grille, more heavily contoured bonnet and re-profiled bumpers – all aimed at providing the CL63 AMG with added appeal against stiff competition from the likes of the Bentley Continental GT and the newly refreshed Aston Martin DB9.
It’s under the bonnet, however, where the most significant changes are concentrated. In place of the outgoing CL63 AMG’s naturally aspirated 6.2-litre V8 is a new twin-turbocharged 5.5-litre V8 – as previewed at the Geneva motor show earlier this year.
With 536bhp at 5500rpm and 590lb ft at 2000rpm in its standard state of tune, the new engine develops 18bhp and 126lb ft more than its predecessor. As part of a new marketing strategy instigated by Mercedes-Benz, buyers can also specify a performance package that lifts the CL63 AMG’s output to an impressive 563bhp and 633lb ft.
Channeling the new engine’s prodigious reserves to the rear wheels is AMG’s seven speed MCT (multi clutch transmission). Based on the seven-speed automatic used in the superseded CL63 AMG, it replaces the torque converter with an automatically operated clutch for more rapid shifts in both automatic and manual modes.
Mercedes-Benz claims the new 2060kg CL63 AMG hits 62mph in 4.5sec and a top speed of 155mph – or 4.4sec and 186mph when running the optional performance package.
