MERCEDES-BENZ has Tesla in its sights. The German brand has confirmed it will launch its first all-electric model in 2018, tipped to be a large sedan to rival the likes of the Tesla Model S.

Likely to sit between its C-Class and E-Class in size, Benz’s first all-electric car will be have a range of 400-500km, will seat five, and will ride on a version of the company’s MRA (Modular Rear Architecture) platform.

Mercedes board members Dr Thomas Weber and Ola Kallenius confirmed to Wheels at the Detroit motor show that the first electric Mercedes-Benz would arrive in 2018.

Respected journalist Georg Kacher had previously reported that Mercedes planned to launch four electric cars in the near future – two sedans and two SUVs. However, Mercedes refused to speculate on other possible models.

Kallenius said the success of Tesla had accelerated Benz’s plans for full electric architecture.

“The case of Tesla shows there is an element of sexiness of the more higher segment of an electric car, so we made a decision to go into that as well,” he said. “In 2018 we will have a very exciting electric vehicle.”

The electric Benz is expected to take design inspiration from the company’s Concept IAA, revealed at the Frankfurt motor show last year – and pictured on this page.

As for speed, Kallenius would not be drawn on whether the electric Benz would match the brutal performance of the Tesla Model S. With Ludicrous mode activated, the Tesla can hit 100km/h from rest in under 3.0sec.

Kacher reports Benz is working on two electric drivetrains: one with a 300kW electric motor driving the rear axle, and a faster version with an extra motor propelling the front wheels.

But while Benz is pushing hard to bring an electric model to market, both Weber and Kallenius raised concerns about its volume and profitability.

Weber added “On the EV side it seems to be hard to make money so far. The best example is Tesla. Overall their results from six years is not really favourable.”

Tesla built and delivered 50,580 cars in 2015, which is a drop in the ocean compared with the 1.87 million cars Mercedes sold over the same period.
