The 301 CR introduced to the Sochaux lines after the summer break of 1933 was less angular, and the word "aérodynamique" featured prominently in Peugeot's publicity for the restyled car.

A commercial version, the 301T, had a tall van body replacing the usual passenger cabin section directly behind the B pillar.

Despite the changes in body design over the lifetime of the Peugeot 301, the configuration of the engine remained the same: a four-cylinder water-cooled unit of 1465 cc.

The 301 was fitted with independent front suspension: it was one of the first volume produced cars to be thus equipped from launch, and benefited from exceptionally good road holding as well as greatly reduced vibration from the steering column by the standards of the time.

The 301 competed in the 8 CV class in terms of fiscal horsepower, and sold approximately 70,000 units during its four-year model run.
