The Matra MS630 was a sports car prototype, the Matra built in 1967 and began sports car racing at the end of 1968.
The Matra MS630 was the next car after the MS620 from 1966. The MS630 is flatter and longer and has large air inlets in front of the rear wheels with a V8 engine from BRM in order to cool better. The MS630 was considered one of the most advanced prototypes of its time.
The previous year was the 24 hours of Le Mans, the highlight of the Matra sports car team. The test run at the 12-hour race at Reims duly went wrong, since both of Mantra's cars turned out early to technical defects. In Le Mans, there were only two MS630 at the start. Matra had learned the lessons from the problems of the previous year and decided against a third vehicle to join with them.
Nevertheless, the race in Le Mans was a failure for Matra. The MS630 by Henri Pescarolo and Jean-Pierre Jaussaud retired after a break from the rear suspension after 43 laps. Just before midnight, the journey of the second MS630 was over. Jean-Pierre Beltoise and Johnny Servoz-Gavin stopped defective valve damage to save the BRM engine.
Back in 1966, Matra had experimented with a 4.7-liter engine from Ford. The MS620 was sent to the assembly in the Le Mans pre-test, but quickly turned out that the engine was too heavy for the more delicate lattice frame. Near the end of the 1967 season, this engine was used in the MS630. Its tube-frame chassis was much stiffer and Henri Pescarolo raced in the "1000 km from Paris" in Montlhéry with Matra-Ford until an engine failure eliminated him from the race.
In 1968, a Matra with a 3-liter 12-cylinder engine was developed. This engine would drive in the future not only the sports car, but also in Formula 1 cars, there the MS11 was used. The MS630 was modified so that it could accommodate the new engine. Its debut was in the car 1000-kilometer race at Spa. At the Le Mans competition in 1968, only one car was used. The Pescarolo/Servoz-Gavin duo raced on Sunday morning and won second place overall as the MS630 broke the suspension and had to give up both.
The MS630 were also sporadically used in the 1969 World Sportscar Championship. Before Matra completed their new model, the Matra MS650 was used. In the 1969 Le Mans, Jean Guichet and Nino Vaccarella came in 5th. This was the race in which the Fettari won.
