Default The new AMG 5.5 liter V8 in detail [video]

Quote:
Mercedes-Benz has produced this video introduction for the new AMG naturally-aspirated 5.5 liter V8 engine.
The unenhanced-breathing M152 engine comes with 310 kW (416 bhp / 422 PS) and 540 Nm (398 lb-ft) of torque and will be first seen in the newly launched 2012 SLK 55 AMG.
The M152 comes with a new feature called AMG Cylinder Management - a cylinder shut-off system that can reduce the V8 to a four-cylinder while still delivering a healthy 230 Nm (170 lb-ft) of torque. That provides for a 30 percent improvement in fuel-economy over the engine it replaces and good for a rating of 8.5 liters/100 km in the new SLK 55 AMG.
The engine is based on the M157 unit - a 5.5 liter twin-turbo V8 introduced last year - with both units sharing the same displacement (bore/stroke).

Whats really impressive about AMG, is that only one person touches an engine as it's being built from start to finish. Not new with premiere brands, but impressive none the less.

Add to that, during the engine dyno break-in, they match the engine to what the actual car does on a race track. The engine goes up and down in sync to the car that was recorded on track for the test.

It is hooked to a computer controled simulator, worth a fortune too. Real cool.
