RACE: 62nd Indianapolis 500

DATE: May 28, 1978

WINNER: Al Unser Sr.

AVERAGE SPEED: 161.363 mph

WHAT HAPPENED: Although he dominated the second half of the race, Unser bent his front wing during a pit stop on lap 180. It allowed second-place finisher Tom Sneva to close within 8 seconds — the second-closest finish in Indy history to that point. Unser's victory was the first at Indy for the Cosworth DFX V8 engine, and the British-based company won the Indy 500 for 10 consecutive years.

NOTABLE: Janet Guthrie finished ninth and later revealed she drove with a broken wrist. Tony Hulman's widow, Mary F. Hulman, delivered the starting command for the first time. It was the final Indy 500 contested before the formation of CART.
