The MS120 was later developed to become the Matra MS120B, Matra MS120C and Matra MS120D. The car was built at Matra's Formula One base at Vélizy-Villacoublay in the southwestern suburbs of Paris, designed under the direction of Gérard Ducarouge and Bernard Boyer. For 1970 following the agreement with Simca, Matra asked Tyrrell to use their V12engine rather than the Cosworth. Jackie Stewart got to test the Matra V12, but since a large part of the Tyrrell budget was provided by Ford, and another significant sponsor was French state-owned petroleum companyElf, which had an agreement with Renault that precluded supporting a Simca partner, the partnership between Matra and Tyrrell ended. Matra chose an all French line up with Jean-Pierre Beltoise and Henri Pescarolo for 1970.
Racing history
1970

The Belgian Grand Prix saw Pescarolo finish sixth with electrical failure while Beltoise scored a third-place finish. The Dutch Grand Prix saw Beltoise 5th and Pescarolo 8th. Then the French Grand Prix, which was Matra's, Beltoise's and Pescarolo's home race, saw Beltoise fifth and Pescarolo 13th, out of fuel. Next, the British Grand Prix was a bad race with both retiring, Beltoise with a wheel problem and Pescarolo with an accident. Then the German Grand Prix saw Pescarolo get sixth place, but Beltoise retire with suspension failure. Next was the Austrian Grand Prix with Beltoise sixth and Pescarolo 14th. Then the Italian Grand Prix saw Beltoise finish third but Pescarolo retire with engine failure. Next, the Canadian Grand Prix saw Pescarolo seventh and Beltoise eighth. Then the United States Grand Prix saw Pescarolo in eighth place, but Beltoise retire with a bad handling car. Finally, it was the Mexican Grand Prix with Beltoise fifth and Pescarolo ninth, although the race was delayed by an hour because of crowd control. Pescarolo was not retained by Matra for 1971 and was replaced by New Zealand'sChris Amon.
1971
Matra kept Frenchman Jean-Pierre Beltoise, and New Zealander Chris Amon joined Matra using the Matra MS120B specification version for 1971. Beltoise was in difficulty following the 1971 1000 km Buenos Aires; racing for the Matra sports car team; he was involved in the accident in which Ignazio Giunti died, and Beltoise's international racing licence was suspended for some time. Amon won the Non-Championship Argentine Grand Prix and finished fifth in the first round in the 1971 season in the South African Grand Prix. Beltoise returned for the Spanish Grand Prix finishing sixth and Amon finished third. The Monaco Grand Prix was a bad race with both retiring with differential failures. The Dutch Grand Prix saw Beltoise ninth and Amon retiring after he spun off. Then came the French Grand Prix which was Matra's and Beltoise's home race, with Amon fifth and Beltoise seventh. Next, the British Grand Prix saw Beltoise seventh and Amon retiring with an engine failure. The German Grand Prix saw Matra only entering Amon and retiring because of an accident. Matra missed the Austrian Grand Prix but entered the Italian Grand Prix, where Matra only entered Amon again who took pole and proved an embarrassment to Ferrari at their home track, and finished sixth. Then the Canadian Grand Prix saw Beltoise back but retiring with an accident, and Amon finish 10th. The final race of 1971 was the United States Grand Prix with Beltoise eighth and Amon 12th. In 1971 Matra signed Amon as team leader which frustrated Beltoise. For 1972 Beltoise left to join BRM.
1972
stayed with Matra, using the Matra MS120C specification version for 1972 before being replaced by the Matra MS120D version mid-season. The Argentine Grand Prix was a bad race for Amon with gearbox problems on the warm-up lap. He then finished 15th in the South African Grand Prix. More gearbox problems followed at the Spanish Grand Prix, before luck came Amon's way with two sixth-place finishes at Monaco and in Belgium. The French Grand Prix saw Amon on pole and he was leading the race until a puncture forced him to pit, but he charged back through the field, bettering the Charade Circuit lap record to finish third. Amon finished fourth in the British Grand Prix and 15th in the German Grand Prix, before another points finish with fifth in the Austrian Grand Prix. Amon's brakes failed in the Italian Grand Prix and he later came in sixth in the Canadian Grand Prix. At the last race of the season, he finished 15th in the United States Grand Prix. Matra pulled out of Formula One afterwards to concentrate on Le Mans.
