Mercedes-Benz SL-Class AMG

  • SL-Class AMG is a super-fast roadster with a metal, electric-powered drop-top
  • Choice of two versions – SL63 AMG and more powerful SL 65 AMG
  • Cheapest SL63 AMG starts from £110k, with the 65 version from just over £128

If a 5.5-litre V8 SL with 556bhp sounds a little too dull, then don’t fret because the Mercedes-Benz SL 65 AMG roadster, with a 6.0-litre V12 producing 630bhp should do the trick.

The car, which follows on from the SL 63 AMG and the standard SL model, has benefited from some serious weight reduction. A substantial 170kg has been cut from the car, helping to improve performance and efficiency.

As well as the rather excessive 630bhp, the V12 produces a rather impressive 1,000Nm of pulling power. These two figures combined means the car is capable of going from zero to 62mph in just four seconds. That might sound impressive, but it's only 0.3 of a second quicker than the SL 63 AMG model.

If you’re looking at buying a car like this then running costs won’t be high on the priority list, but they have been improved compared to its predecessor. Aided by the addition of a seven-speed automatic gearbox and stop/start, fuel economy has risen to a claimed 24.4mpg, up from 20mpg.

Emissions have dropped from 333g/km down to 270g/km, though this does mean you’ll still pay £1,000 in first-year tax and £460 per year thereafter. This latest version gets the new ‘brand face’, according to Mercedes.

The main focus of this is the twin-blade radiator grille along with LED light surrounds, chrome bonnet fins and two strips down the side of each wing. It also comes with AMG sports suspension, speed-sensitive steering, a three-stage stability control system and a limited slip-diff.

The basic SL 63 AMG starts from £110,000, while the slightly quicker SL 65 AMG costs from just over £168,285. Look out for the Parkers full Mercedes-Benz SL-Class review coming soon.
