Minerva M4 History

Facing financial ruin from the Depression, Minerva's final own-design model was the M4, a 2-litre four-cylinder introduced in 1934. After seven years of building nothing but large sixes and eights, the M4 represented a dramatic downsizing: it used a three-speed synchromesh gearbox, mechanical brakes, and pillarless saloon bodywork, while retaining the marque's signature Knight sleeve-valve engine.

The M4 did not sell well. The brand identity Minerva had built over three decades was inseparable from large, whisper-quiet luxury cars, and Depression-era buyers seeking a smaller car had no particular reason to choose an expensive Belgian make over more established alternatives. The failure of the M4 accelerated the company's decision to merge with Impéria in 1935, ending independent Minerva production.
