While the sleek Mercedes-Benz SL550 for the 2013 model year is about two inches longer and wider, its aluminum frame is more than 200 pounds lighter than the previous model. Most of the body panels are also aluminum, and high-strength steel is used in the roof pillars. Overall, the new SL body is about 20 percent stiffer than the car it replaces.Mercedes-Benz SL550 is powered by an efficient and refined new V8 engine that gets up to 14% better fuel economy while producing more power – an astounding feat, considering that increasing power or fuel economy is usually an either-or scenario. The V8 features direct fuel injection, twin turbochargers and multi-spark ignition.
Based on its highly successful 5.5-liter predecessor, the new 4.6-liter V8 engine has 20 percent smaller displacement but generates more horsepower and torque – 429 horsepower and 516 lb.-ft. of torque. Its smaller displacement is more than offset by the power boost of its twin turbochargers and an air-water intercooler.The 2013 Mercedes-Benz SL550 engine comes with an innovative ECO stop-start system. Whenever the car stops with the brake pedal depressed, the engine is automatically turned off to save fuel. As soon as the driver touches the accelerator pedal, the engine computer selects the piston that is in the best position for first ignition, and the direct fuel injection and multi-spark systems work with a starter motor to seamlessly re-start the engine.
Mercedes-Benz was the first manufacturer to make emergency calling a standard feature, and the new SL marks the debut of mbrace2, the next generation of telematics innovation that gives drivers top-of-the-line features related to safety, infotainment, personal assistance and vehicle care.
