No lie
Technology from Formula 1′, it is perhaps the most common lie in automotive journalism, but in the case of the turbo of the new Mercedes-AMG C63S E Performance it is actually true for once.
Just like in Formula 1 engines, there is an electric motor between the turbine and the compressor wheel. Such an electric motor can rotate quickly almost immediately, so that the compressor wheel immediately starts to supply pressure and extra air can therefore immediately be pressed into the power source, which produces more power. We previously saw something similar on various diesel engines at Audi, but there the electric motor was only connected to a compressor wheel. In Mercedes’ setup, if enough exhaust gases flow past the turbine wheel, the turbo can work just like any other. In practice, this setup avoids a large part of the turbo lag, because you don’t have to wait for sufficient pressure. The turbo can also run for a long time, because after the ‘start-up phase’ it is no longer dependent on the power supply. Although the 2.0-liter four-cylinder turbo engine produces almost 250 hp per liter of specific power, the combustion engine feels razor-sharp and extremely powerful. The best of both worlds and truly Formula 1 technology for public roads.
When to take a driving test with the Mercedes-AMG C63S E Performance? We have already featured this in the magazine, in issue 38 of 2023, but on Friday January 19, 2024 you will see in a video what the fast version as an Estate can do in a double test against the BMW M3 Touring.
