In three generations, the Mercedes C63 AMG has undergone major changes: atmospheric, first supercharged, then hybrid, the mechanics will reach new heights in the new version, released in 2022.
The Mercedes C63 AMG, in the same way as the BMW M5 or Audi RS6, has become one of these “institutions” of German road racing. Some have been made even more popular by certain influencers and media personalities… As a result, anticipation grows as time goes on, so we are faced with a refurbishment of a car that has undergone major changes since 2008: it was launched from day one. with a large naturally aspirated 6.2 V8 (M156), later converted to a smaller but more powerful engine powered by two turbos, The C63 AMG will change again soon, completely changing the recipe. Again. This time, however, the V8 has been replaced by a four-cylinder engine powered by a particularly powerful electric motor.
The most powerful 4-cylinder in history?
The M139 engine was introduced in 2019 in the compact AMG lineup, following the M133, already one of the world’s most powerful four-cylinder engines. But the latter’s 381 hp pales in comparison to the current A45 AMG engine, which claims 421 hp from just two liters of displacement. Therefore, we have a certain power of more than 200 horsepower per liter, and the record should be broken with the new C63 AMG.
The sedan and station wagon will combine the M139 with an electric motor for a combined output of around 650 hp. In detail, according to the first elements collected at the dawn of the car’s presentation, the thermal block can demand about 450 hp: this would be unprecedented for a serial engine of this size. But it’s not the first: Volvo launched a 2.0 450 hp engine in 2014, unfortunately unfollowed. It should be said that the Swedish company has probably reached the limits of the VEP4 engine: to achieve such a cavalry, the compact four-cylinder got the right to two conventional turbos and a third electric compressor!
Mercedes will therefore take a hard hit with the M139, especially since the choice of four cylinders can offer a significant advantage: less weight in the nose of the car and possibly more balanced masses. It would still be necessary that the electric motor (definitely located on the rear axle) not put too much weight on the stern: on its own it could produce more than 200 horsepower…
