Meanwhile, a more stringent focus on aerodynamics, in combination with more efficient motors and a new software stack, will boost range by up to 30%, the firm has said.
Like today’s BMW 4 Series and BMW 5 Series, the next-generation 3 Series will be sold both with pure-electric and combustion power, with BMW committed to maintaining a flexible powertrain offering across its line-up in the run-up to going all-electric. The firm is one of few mainstream car makers to have not set a date for the end of combustion car sales, though on current planning will have to sell only EVs in the UK and Europe from 2035.
The firm is working to make its current engines compliant with upcoming emissions regulations, though has not yet confirmed what the offering will be for the next 3 Series.
The current, G20-generation model is available with a choice of either 2.0-litre four-cylinder or 3.0-litre straight-six petrol engines, or a PHEV with an EV range of 63 miles, having dropped all diesel engines in an update earlier this year.
While the Neue Klasse concept and this prototype have previewed the saloon variant, it is expected that the strong-selling 3 Series Touring will return, providing a rival for the upcoming electric Mercedes CLA Shooting Brake and Audi A4 E-tron Avant.
