Penske PC-5

The Penske PC-5 was Penske Racing's first USAC Indy car. It was designed by British designer Geoff Ferris, and was constructed for competition in the 1977 season. Having driven the car for the latter part of the season, Tom Sneva won the team's first championship.^[2] It was notably the first time Penske used its own chassis at the Indy 500, and the first car to clock a qualifying single-lap record of over 200 mph (320 km/h) at Indianapolis Motor Speedway.^{[3][4][5][6][7]}
