23 Jul 2011|3,777 views
The new engine, codenamed M152, is based on the M157 5.5-litre V8 bi-turbo powerplant that is used in the E 63 AMG, CLS 63 AMG, S 63 AMG and CL 63 AMG. The naturally-aspirated engine gains an additional 62bhp and 30Nm of torque from the previous SLK 55 AMG's unit, for a new power output of 422bhp and 540Nm.The new powerplant is made from aluminium, and features the AMG Cylinder Management system that can shut off four-cylinders from 800 to 3,600rpm to improve fuel efficiency. Mercedes-Benz says that the switch from four to eight-cylinder operation is “immediate and imperceptible” taking a mere 30 milliseconds at 3,600rpm.
The German carmaker adds that as a result of the new Cylinder Management system, the SLK 55 AMG is able to return a fuel consumption figure of 8.5L/100km, a 30% improvement over the outgoing model. The all new SLK 55 AMG roadster is expected to be unveiled at the Frankfurt Motor Show in September.
