As BMW car bodies glided down an assembly line in Munich recently, showered by sparks from robotic welders, it was hard to tell which vehicles would be powered by batteries, fuel-burning engines or both. In the view of many analysts, that is not a good thing.

The German automaker’s electric vehicles are made on the same assembly line as gasoline cars and look similar from the outside. That approach, using the same basic body for electric, hybrid, gasoline and diesel cars, has been viewed as an awkward and inefficient compromise some established carmakers have deployed as they struggle to compete with Tesla and emerging Chinese automakers that produce cars designed solely for battery power.

But confounding the pundits, BMW’s strategy has paid off. The company sold 376,000 electric vehicles last year, including some under its Mini brand, a 75 percent increase from the previous year. In the luxury segment, BMW was second only to Tesla, which remained dominant with 1.8 million cars. Electric vehicles accounted for 15 percent of BMW sales in 2023, up from 9 percent the previous year.

The company’s growth comes as sales of electric vehicles have risen at a slower pace overall around the world. What is even more surprising is that BMW, unlike General Motors or Ford Motor, made a profit on the electric vehicles it sold.

BMW’s experience suggests there is hope for at least some established carmakers as Chinese carmakers like BYD start to export cars to other Asian countries, Europe and Latin America. As electric vehicles move into the mainstream, the popularity of BMW cars suggests that many buyers prize the familiarity and workmanship of longstanding carmakers and remain wary of newer brands.

If so, BMW’s approach could show a path to other automakers that have been manufacturing automobiles for decades but have made little headway in the transition to battery-powered vehicles.
