New Mercedes-Benz SL 63 AMG exceeds expectationsBy Chris Walsh

Enhanced performance, reduced weight and lower fuel consumption. That’s the tag-line for the new Mercedes-Benz SL 63 AMG. And the high-performance roadster (in that typically German manner) has managed to exceed expectations with a boost in output, a systematic lightweight construction and a 30 per cent improvement in fuel efficiency.
Thanks to an all-aluminium bodyshell (similar to that of the SLS AMG) the SL 63 AMG’s weight has been reduced by a credible 125kg. So with a new kerb weight of 1845kg, combined with an output of 537bhp and 800Nm of torque, means the new model is the perfect recipe for unparalleled dynamism and superior driving.
However, if the AMG performance package is specified, these figures rise to 564bhp and 900Nm of torque. The result is increased acceleration from 4.3 to 4.2 seconds to 62mph and 12.9 to 12.6 seconds to 125mph respectively. Top speed is electronically limited to 155mph, although this rises to 186mph with the AMG Performance package is present.
Performance also comes courtesy of an enhanced sports suspension, a new AMG speed-sensitive sports steering, a high-performance compound brake system and an AMG SPEEDSHIFT MCT 7-speed sports transmission. Combined consumption comes in at 28.5mpg for both power outputs, which is a 30 per cent improvement over the outgoing model.

The eight-cylinder powerplant features a combination of innovative high-tech components for high power output. In addition to spray-guided direct petrol injection, the engine boasts an all-aluminium crankcase with twin turbochargers, four valves per cylinder, camshaft adjustment, air/water intercooling and an ECO start/stop function. Oh, and the AMG sports exhaust system helps to put that all in perspective with two chromed twin tailpipes producing a distinctive engine sound.
Ola Källenius, CEO at Mercedes-AMG GmbH states: "The new SL 63 AMG is yet another masterpiece from Mercedes-AMG. Be it driving dynamics, lightweight construction or efficiency – the SL 63 AMG represents a giant leap forward. Following on from the SLS AMG Roadster and the SLK 55 AMG, it now makes our unrivalled roadster family practically complete."
The SL 63 AMG leaves the factory fitted with five-twin-spoke AMG light-alloy wheels painted titanium grey with a high-sheen finish. Around these are 19” front and 19” rear tyres. But AMG claims an upgraded 20” rear tyre option will actually help to reduce the unsprung mass.
The flagship SL 63 AMG displays the hallmark styling elements of a super-high-performance car from Affalterbac. The distinctive AMG body styling comprises of a front apron with large air dams, AMG-specific LED daytime running lamps and a lower cross strut in silver chrome.
Among the other eye-catching features is the new AMG radiator grille with a double louver in silver chrome, the side sill panels and the "V8 BITURBO" logos on the vent grilles with fins in silver chrome. At the rear, the AMG spoiler lip, the two chromed twin tailpipes of the AMG sports exhaust system and the diffuser style rear apron with body-coloured insert conclude the styling.
