203 was launched at the Paris Motor Show in October. The 1290 cc four-cylinder engine is unusual in its 'oversquare' cylinder dimensions, and hasr the hemispherical combustion chambers in the light metal cylinder heads.
With a team of drivers working in relays, this car appeared at Montlhéry and broke three speed reCords for the under 1100 cc class. The car managed 1,000 miles (1,609 km) at an average speed of 144,5 km/h (89.8 mph), 2,000 Miles (3,218 km) at an average speed of 145 km/h (90.1 mph) and achieving an average of 144,5 km/h (89.8 mph) over 12 hours. A few weeks later in October, Darl'Mat 202 was exhibited in public at the Paris Motor Show.
