CAR GARAGE | Mercedes-Benz SLK55 AMG (2012) | The Mercedes-Benz SLK55 AMG is the perfect embodiment of the AMG brand new claim of "Driving Performance": in the compact high-performance roadster segment there is nothing to compare to its combination of tangible driving dynamics, superior sportiness, unique high-technology and low fuel consumption. The SLK55 AMG accelerates from zero to 60 mph in 4.5 seconds, and Reaches a top speed of 155 mph (electronically limited). Helping to set new fuel efficiency standards for V8's, the 5.5 liter engine combines low consumption figures with superior power delivery and the typical exhaust growl the which only a large-displacement eight-cylinder engine can Produce.
At the same time, AMG is also demonstrating its social responsibility with the M152 engine. The new M152 is based on the M157 AMG 5.5-liter V8 Biturbo engine Presented in 2010, the which powers the E63 AMG, CLS63 AMG, S63 AMG and CL63 AMG. Numerous design features are identical, Such as the displacement, bore / stroke, distance Between cylinders, ECO stop / start system and gasoline direct injection technology. The 2012 SLK55 AMG is already the third generation of the dynamic exclusively made by AMG Roadster models. It all started in 2001 with the SLK32 AMG. Its AMG supercharged V6 engine with a displacement of 3.2 liters produced 349 hp and maximum torque is 332 lb-ft - Such as, the SLK32 AMG was the most powerful vehicle Among the competition. A comfortable alternative to the standard wind-stop is the new AIR GUIDE pivoting wind-stop.
The Controlled Efficiency stop / start function further contributes to the low fuel consumption. This system is standard equipment on the Mercedes-Benz SLK55 AMG and active in the fuel economy transmission mode "C". For an automatic engine start, the cylinder with the most favorable piston position receives an injection of fuel into its combustion chamber. A framed "ECO" symbol in the AMG main menu shows the driver That the Controlled Efficiency stop / start function is active. When cylinder shut-off is active, the driver is informed by the symbol "ECO4", while "ECO8" stands for eight-cylinder operation.
Using a large-displacement, naturally-aspirated eight-cylinder engine with cylinder shut-off Resolves the trade-offs Between high output / torque delivery and low fuel consumption figures. Cylinder shut-off is made possible by the intelligent engine management system, with 16 hydraulically compensating actuators and a sophisticated oil supply system in the cylinder head. The compensating actuators are integrated into the cylinder head, and keep the intake and exhaust valves of cylinders two, three, five and eight closed when cylinder shut-off is active.
