2013 Mercedes-Benz SL65 AMG | This white 2 door Mercedes Convertible, showing 25183 miles, features a 6.0-L V12 SOHC 36V Turbo engine mated to a 7-speed automatic transmission. It includes an infotainment system and digital gauge display, leather seats, power windows, automatic convertible top with sunroof. This is a rear-wheel-drive car with rack and pinion steering. he AMG 6-litre V12 biturbo engine with the designation M 279 is based on the M 275 engine used previously and has been comprehensively revised for the new SL 65 AMG. New exhaust gas turbochargers with an increased spiral cross-section, new manifolds and wastegate ducts with optimized flow characteristics increase the engine output by 13 kW (18 hp). The multi-spark ignition with twelve double ignition coils not only results in smoother running, but also enables even more effective combustion in combination with a new engine management system with higher performance and optimized cylinder heads. The resulting reduction in exhaust emissions is also due to a large extent to the optimized catalytic converter system. The newly developed AMG sports exhaust system, which has a pipe layout with enhanced flow characteristics, is 3.2 kilograms lighter as a result of a reduction in the wall thickness. But it is not just the inner qualities of the AMG 6-litre V12 biturbo engine that impress. The powerplant's looks are as inspiring as its performance: the high-quality carbon-fibre and aluminum engine cover reflects the exceptional character of the powerful twelve-cylinder unit. AMG SPEEDSHIFT PLUS 7G-TRONIC. AMG has combined the 6-litre V12 biturbo engine with the AMG SPEEDSHIFT PLUS 7G-TRONIC. The seven-speed automatic transmission with its wide gear ratio spread enables a significantly lower engine speed and helps to reduce fuel consumption. A new fuel economy torque converter, bearings designed for reduced friction loss and the transmission-oil thermal management system are responsible for a further increase in the efficiency of the power transmission system. The AMG SPEEDSHIFT PLUS 7G-TRONIC has four different driving modes - Controlled Efficiency (C), Sport (S), Sport plus (S+) and Manual (M) – which can be selected at the push of a button on the center console. In 'C' mode the ECO start/stop function is permanently active. The compelling, dynamic character of the driving experience is made all the more vivid by the automatic double-declutching function during downshifts and through the brief, precisely defined interruption of ignition and fuel injection during upshifts under full load; the latter functionality has the additional benefit of reducing the shift times. This vehicle is the ultimate standard for the SL class of Mercedes vehicles. VIN# WDDJK7KAXDF016244. This vehicle will sell at public auction on Saturday, June 25th.
