IN 1970, Matra merged with Simca. For the 1970 season, Tyrrell was asked by Matra to use Simca's V12 in place of the Cosworth. Simca was a subsidiary of the American company Chrysler which was competition for Ford. Stewart tested the Matra V12. He did not think it was as good as the DFV. Ford gave Tyrrell a large part of the money they needed to race. The team also got money for the French petroleum company Elf. Elf had an agreement with Renault that did not allow them to provide money to anyone who was partnered with Simca. Because of this, Ken Tyrrell had to buy a March 701 chassis as temporary solution while making his own car in secret.
