BMW has built numerous inline fours, inline sixes, V8s, and a handful of V12s, as well as a few inline three-cylinder engines. However, the famed German automaker has only ever made a single V10 engine for its road cars. That engine was the one and only S85 V10 engine, which has been employed by only two of BMW’s thoroughbred M cars. Although we eventually saw this engine used in a cool restomod, it was not used in any of BMW’s other models.
