The bold electric Mercedes C-class

Article by Tobias Selerit

The shift to electrification is starting to blur traditional class boundaries—and the upcoming Mercedes-Benz C 400 electric might be one of the clearest examples yet. Based on early technical details, this is no mere evolution of the C-Class formula. At nearly 4.9 meters in length, the electric Mercedes C-class stretches well beyond what we’ve historically associated with the segment. The wheelbase alone grows by 97 mm compared to its predecessor. Visually and proportionally, it appears to channel the flagship Mercedes S-Class.

Rear-axle steering further reinforces that dual character. It’s a feature once reserved for high-end models, now trickling down to give this electric C-Class both improved agility in tight urban settings and greater stability at speed.

Under the skin, the numbers are anything but modest. C 400 is the first version. A 94 kWh battery feeds a dual-motor 4WD setup producing a combined 360 kW, launching the car from 0 to 100 km/h in just 4.0 seconds. That firmly places it in performance territory traditionally occupied by AMG variants.

But what stands out isn’t just raw power—it’s how it’s deployed. The drivetrain uses a two-speed transmission: a short 11:1 first gear for strong initial acceleration, followed by a longer 5:1 second gear optimized for motorway efficiency. It’s a rare and technically intriguing solution in the EV world, where single-speed setups dominate. Porsche Taycan was the first electric car that had 2-speed transmission.

The C 400 has a very fast charging capability with peak charging power reaching 330 kW. That is more than on benchmark Porsche Taycan.

Mercedes-Benz has clearly invested heavily in refinement. Extensive sound insulation, combined with elastomer-mounted suspension components, aims to decouple road imperfections and reduce noise intrusion. The result is a cabin experience that edges close to luxury-class.

Thermal comfort is another area where electrification brings tangible benefits. In cold conditions, the interior can heat up twice as fast as in a combustion-powered equivalent—an often overlooked but highly relevant advantage in real-world use.

Inside, the technological centerpiece is the optional 99 cm-wide Mercedes-Benz Hyperscreen, spanning the dashboard in a seamless glass surface. It transforms the cockpit into a fully digital environment, blending infotainment, instrumentation, and passenger interaction.

The sense of occasion continues with ambient lighting that flows from the dashboard into the doors and up into the optional Sky Control panoramic roof. Paired with a Burmester sound system, the cabin aims to deliver not just transport, but immersion.

Taken as a whole, the electric C 400 doesn’t simply electrify an existing Mercedes template—it repositions the model. With its increased size, advanced drivetrain, and luxury-oriented features, it steps into territory once clearly reserved for higher segments.

Mercedes-Benz has created something more significant than just another EV: a model that completely redefines the C-Class.
