Mercedes-AMG unveils its new hybrid four-cylinder engine

Rumors about a possible hybrid four-cylinder engine began circulating online some time ago. Everything pointed to the next batch of Mercedes-AMG models using this powertrain, especially considering that the current Mercedes-AMG A 45 S already boasts the world's most powerful four-cylinder engine. Today, the three-pointed star confirms the rumors and gives us a sneak peek at the engine that will power, among other vehicles, the future Mercedes-AMG C 63 S.

In this way, the German sedan leaves behind the colossal 8-liter biturbo V4.0 which has brought so much joy in favour of a more efficient engine that is committed to caring for the environment. And although for many this movement can be interpreted as an outrage or a heresy, the truth is that Mercedes-AMG guarantees high doses of sportiness with this new engine.

To develop it, the brand's engineers started with the same 2.0-liter engine found in the A45; however, they used an electric turbocharger called the MGU-H , which they claim completely eliminates the characteristic turbo lag. This technology comes from Formula 1 and is also used in the Mercedes-AMG Project One.

This system features a small electric motor inside the turbine that generates 6 kW of power. It is powered by a 400-volt onboard electrical system and can reach a maximum speed of 156.000 revolutions per minute. This motor allows the turbine to be accelerated before the exhaust gases complete their function, effectively eliminating turbo lag.

Furthermore, the Mercedes-AMG C 63 will feature an electric motor that delivers an additional 204 hp. This way, the four-cylinder hybrid engine will far surpass the V8, offering a total output of 643 hp , managed by an automatic transmission and the intelligent 4Matic+ all-wheel-drive system, which allows power to be sent solely to the rear axle if desired.

For now, the German firm hasn't revealed an arrival date, but we can assume that, given the mechanical components are already complete, we'll soon see the new and promising Mercedes-AMG C 63. This Mercedes-AMG sedan will usher in a new era for the brand, setting the standard for future sports models.
