Mercedes reveals new SL65 AMG

Is the SL63's 560bhp not enough for you? Step forward, SL65...

In this world of engine downsizing, electric vehicles and Ferraris coming with Stop-Start technology, you would be forgiven for thinking that a major car manufacturer like Mercedes would be starting to tone down their performance car range. After all, the latest SL63 SMG has ditched the incredibly 6.2 litre V8 for a more eco-friendly twin-turbo 5.5 litre V8.

But worry not, performance car fans, because Mercedes has revealed that there will still be an SL65 AMG sitting at the top of the SL tree. The ’65 variants have always been that little bit more unhinged than the ’55 and ’63 engined cars that sat beneath them in the past and that looks set to continue with the latest variant.

The engine is basically the same twin-turbo 6.0-litre V12 as the old SL65 AMG but receives new exhaust gas turbochargers, with an increased spiral cross-section, new manifolds and wastegate ducts which is enough for Mercedes to give the engine a new code - the M279 rather than the M275.

Power jumps up to a mammoth 624 bhp, with an even more incredible 738 lb/ft of torque. When you also realise that the new SL65 is 170 kg lighter than the model it replaces you can imagine that the performance stats are going to be impressive, which they are. The 0-62 mph dash takes just 4.0 seconds while 0-125 mph is dispatched in 11.8 seconds. As is usual with fast Mercs, the top speed is limited to 155 mph, but with the AMG Performance Pack this can be raised to 182 mph.

Visually the SL65 differs very little from the SL63 AMG, in fact the only way you’ll be able to tell other than the rear badge is the addition of a small strip of chrome above the lower spoiler and the ‘V12 Bi-Turbo’ badges on the side.

Prices haven’t been released, but you shouldn’t expect any change from £160,000 given the previous pricing of these models. Oh, and as a nod to the eco-warriors out there, the SL65 AMG does come with Stop-Start technology, though you can turn it off…
