MERCEDES-BENZ

The 2.0 engine of more than 400hp brand

The base version of the engine delivers 387 hp and 480 Nm of torque. Both will be under the hood of the A45 AMG, CLA 45 AMG and GLA 45 AMG. The engine is brand new because low emissions and consumptions go into collision with more power, less weight and a different storage of the engine accessories. So, as Ralf Illenberger, the boss of AMG's engine development department, said, "from the previous engine there are some nuts and bolts, nothing more."
The M133 was an engine that had a torque curve similar to that of a diesel engine, that is, it rose rapidly to a certain level. The M139 is different, with a torque curve that is ... a curve and rises in crescendo and not in an abrupt way.
Confirmed: The AMG 2.0 liter M 139 engine will deliver 421 hp and 500 Nm meters, plus 41 hp than the previous M 133 engine and a further 25 Nm of torque, exhibiting a specific horsepower of 211 hp per liter.
