► SL 63 AMG - FIRST DRIVE

www.youcar.tv Superior performance and high efficiency the SL 63 AMG is available with a choice of two power outputs for the first time. The AMG 5.5-litre V8 'biturbo' (twin-turbocharged) engine delivers 395 kW (537 hp) and 800 Nm of torque. If the AMG Performance package is specified, these figures rise to 415 kW (564 hp) and 900 Nm -- more power than any other competitor in this segment. The result is high-calibre performance, as underlined by the acceleration from 0 to 100 km/h in 4.3 or 4.2 seconds, and to 200 km/h in 12.9 or 12.6 seconds respectively. Top speed is 250 km/h (electronically limited), although this rises to 300 km/h (likewise electronically limited) with the AMG Performance package on board. NEDC combined consumption comes in at 9.9 litres per 100 kilometres for both power outputs -- a full 4.2 litres or 30 percent lower than for the outgoing model. The eight-cylinder powerplant with the abbreviation M 157 features a combination of innovative high-tech components for high power output, and it delivers exemplary, low fuel consumption. In addition to spray-guided direct petrol injection, the engine boasts an all-aluminium crankcase, twin turbochargers, four valves per cylinder with camshaft adjustment, air/water intercooling, alternator management and an ECO start/stop function. The weight-optimised AMG sports exhaust system with two chromed twin tailpipes produces a distinctive engine sound.
