The car was launched with a four-cylinder water-cooled engine of 1991 cc with poppet valves. With its claimed 55hp (41 kW) the standard bodied car could achieve a top speed of 120 kmh (75 mph) at 4. 000 rpm. In 1938 the capacity was raised to 2142 cc with the introduction of the Peugeot 402B, stated output now being 60 horsepower (45 kilowatts). Given the wide range of body lengths and styles offered, there was and is correspondingly wide range of different performance figures quoted for the standard-engined 402.
