Tuhia he haere tonu mō tēnei wāhanga - I waenganui i te tau 1967 me te tau 1971, i whakamahia ngā pūkaha turbine Pratt &amp; Whitney i te American Championship Car Racing me te Formula One. Ko te STP-Paxton Turbocar i whakahaere i te 1967 Indianapolis 500
tae noa ki te wā i kore ai tētahi waka e wha ngā poro mai i te mutunga. I uru a STP ki nga Lotus 56 e wha i te 1968 Indianapolis 500. Kotahi te motokā i taka i te wā o te tohu. E rua o nga waka e toe ana i tohu tere me te tuarua tere, engari ko te tokotoru katoa i reti mai i te whakataetae. I whakaarohia nga motuka turbine he ture i mua i te whakataetae o te tau e whai ake nei, no reira ko te rangatira o Lotus a Colin Chapman i whakawhanake i te motuka hei whakamahi i te Formula One me te 56B hou i whakataetae i roto i te hawhe tatini o nga whakataetae Formula One i te tau 1971.
