1960s
With the help of Elf and Ford, Tyrrell then achieved his dream of moving to Formula One in 1968 as a team principal for the team officially named Matra International, a joint-venture established between Tyrrell's own privateer team and the French auto manufacturer Matra. Stewart was a serious contender, winning three Grands Prix in the Tyrrell-run Matra MS10. The car's most innovative feature was the use of aviation-inspired structural fuel tanks. These allowed the chassis to be around 15 kg lighter while still being stronger than its competitors. The FIA considered the technology to be unsafe and decided to ban it for 1970, insisting on rubber bag-tanks.
