1973 2002 goes turbo
GM dabbled with turbos in the early ’60s, but the ’70s marks their mainstream adoption. BMW uses a KKK blower for the 2002 Turbo, giving the sweet little fourbanger a 167bhp kick. But its timing – just as the oil crisis bites – couldn’t be worse. Later F1-spec BMW turbo fours make 1400bhp.
