Video: 2012 Mercedes-Benz SLK 55 AMG V8 with cylinder deactivation technology

September 28, 2011

Mercedes-Benz has made a new video to show off its new naturally-aspirated 5.5-litre AMG V8 engine (M157) that will feature in the new 2012 Mercedes-Benz SLK 55 AMG. The engine is based off the new twin-turbo 5.5-litre AMG V8 (M152) that will creep under the hood of the 2012 Mercedes-Benz E 63 AMG, and other Mercedes-Benz AMG models.

The 5.5-litre AMG V8 engine (M157) in the 2012 Mercedes-Benz SLK 55 AMG loses the turbochargers of the twin-turbo 5.5-litre AMG V8 (M152) its based on, and features a new air intake, direct injection, optimized crankcase, tailored cylinder heads, variable valve timing, stop/start technology and AMG Cylinder Management – which can deactivate four-cylinders when they are not needed.

This equates to 310kW and 540Nm, shooting the 2012 Mercedes-Benz SLK 55 AMG from 0-100km/h in 4.5 seconds… BMW 1 M Coupe eat your heart out.

The car will sing all the way to a limited top speed of 250km/h. And if you’re keen on green, it’ll drink a piddling average fuel consumption of 8.4L/100km. Not bad for a high-performance V8 engine.

Australian pricing and release dates for the new 2012 Mercedes-Benz SLK 55 AMG have not yet been released.
