However, the powertrain developers don’t work alone to achieve this goal, as approximately 200 employees at Mercedes-Benz in Sindelfingen are directly or indirectly involved in the hybrid powertrain project.
The C 350 e is a true wonder of efficiency. It boasts 205 kW of output but only needs 2.1 litres of fuel to travel 100 kilometres. This corresponds to CO₂ emissions of 48 grams per kilometre. Despite all this efficiency, the comfortable sedan is as lively as a sports car: In its Sport Plus mode, the vehicle accelerates from 0 to 100 km/h in 5.9 seconds. A premium sedan that is as dynamic as a sports car and as environmentally friendly as a compact — how can that be?
We asked someone who should know the answer: Uwe Keller, who has a Ph.D. in engineering and is also the Project Lead for the centrepiece of the C 350 e: the hybrid powertrain. “Ultimately, the secret lies in perfect interaction,” says Keller. “We matched all of the systems, parts, and components down to the last detail in order to ensure that the combustion engine, the transmission, and the electric drive work together perfectly. In combination with our intelligent drive system management concept, this results in a high level of efficiency and outstanding handling.” Efficiency is also the main objective of the project team led by Keller.
