1 PORSCHE 917/30
This is not just the greatest Penske sports-racer, but one of the finest competition cars of all time. Porsche and Penske ended Mclaren’s domination of Can-am with the revolutionary turbocharged 917/10 in 1972, and the 1100+bhp 917/30 was the ultimate iteration. Mark Donohue, who did much of the development work, won six of the eight rounds in ’73 on his way to the crown. Porsche’s domination led to Can-am rule changes, but there was still time for a closed-circuit land speed record at Talladega in ’75, Donohue averaging 221.12mph.
