Now more than ever, automotive engineers have to chase efficiency wherever they can. In an internal-combustion engine, a turbocharger is a great way to boost power and efficiency for an engine of a given displacement, and over the last decade we've seen a proliferation of downsized, turbo engines replacing larger naturally aspirated units. Yet, the turbocharger itself is far from perfect.
It's easy to think that the sole job of an electric turbocharger is to reduce lag. That's what I thought, and indeed, that is a huge benefit of its use. In very simple terms, a larger turbocharger—with larger turbine and compressor wheels—can force more air into an engine, making more power, but the bigger you go in turbo size, the longer it takes to achieve the target boost level.
According to Jan Habermann, one of the engineers behind AMG's application of e-turbos, the company wanted to give the C43 a more special engine than its predecessor, which used a V-6 shared with non-AMG products. The M139 is made by hand at AMG's factory in Affalterbach, and while it can be found in AMG's 45-series cars, those have 12-volt electrics, and thus, traditional exhaust-gas turbochargers.
Funny as it might be, it's easy to see the logic when you consider that the motor on the C63's electric turbo has just 6 kW , so it takes a lot less energy to spin that up than it does to spin a drive motor 25 times as powerful.MERCEDES-BENZ AG - GLOBAL COMMUNICATIONS MERCEDES-BENZ CARS & VANS
