Mercedes-Benz AMG has upped the power of its SL 63 AMG by a substantial 48hp for a total output of 585hp – with NO penalty in economy or emissions.
Even more significantly, the Mercedes SL 63 AMG also gets a 100Nm torque boost to an amazing 900NM. That’s 663lb ft, or an equally amazing 110lb ft more than a Porsche 911 Turbo S…
The mighty engine is the same 5.5-litre V8 turbo motor as that used in S versions of the E 63 AMG, with an identical power output but even more torque.
Whereas the E-Class AMG S gets a four-wheel drive option, the SL 63 AMG doesn’t offer it. Instead, Mercedes sensibly fits an AMG rear limited-slip differential as standard, with a 40% locking effect.
It spends the money here instead of detail jewellery – if customers do want an AMG carbon fibre engine cover, says Mercedes-Benz UK, they can still have one, but only if they pay £1,580.
The uprated SL 63 AMG arrives at Mercedes-Benz dealers from June 2014, and will cost £112,510. It goes on sale at the same time as the new SL 400 which Motoring Research reported on earlier this week.
Prices for that have now been confirmed too: in SL 400 Sport guise, it will cost £72,500.
