Mercedes-AMG Four-Cylinder Wins Two Engine of The Year Awards

Unveiled last year in the bonkers Mercedes-Benz A 45 AMG but finding itself in the CLA 45 AMG and the GLA 45 AMG as well since, the M133 engine is currently the most powerful production four-cylinder in the world.
Developing no less than 360 hp and 450 Nm (332 lb ft) of torque from a displacement of just two liters, the small inline-four is also the first ever AMG engine with less than five cylinders, and boy is it an awesome first try in this segment.

The powerplant has been so revered in the last year that it even managed to win not one but two International Engine of The Year awards earlier today – one in the “1.8-liter to 2-liter” category and another one in the “New Engine” category.

The boys and girls (well, mostly boys) in Affalterbach hadn't been in the winner's circle in this global competition since 2013, when the now legendary M156 6.2-liter V8 was also receiving two awards in two different categories, only then it was for the second time in a row.

Getting back to the twin-scroll turbocharged M133, we have nothing but praising words for it as well, after we had the chance to experience its tremendous power and torque in a Mercedes-Benz A 45 AMG a little over a week ago.

Apart from the twin-scroll turbocharger and direct injection, the M133 also features a forged crankshaft, connecting rods and pistons, meaning that its internals are very much related to a racing engine.

With a massive charging pressure of 1.8 bar (26.1 psi), the throttle response isn't exactly instantaneous at lower revs, but once the turbocharger gets moving it offers its driver a never-ending wave of kicks in the back with each gear change. In short, this is by far the best performance engine in its segment and the two recent awards come to reinforce that opinion.
