RACE: 18th Indianapolis 500

DATE: May 30, 1930

WINNER: Billy Arnold, Harry Hartz

AVERAGE SPEED: 100.448 mph

WHAT HAPPENED: Billy Arnold had one of the most dominating displays in Indy history. It wasn't just that he became the third pole winner to win. He did it in record-breaking style. After Louis Meyer passed Arnold on the first lap, Arnold retook the lead on Lap 3 and never gave it back. The 198 laps led in a single race is still an Indy record. Arnold became the first driver to win the race in less than five hours without a relief driver and the second to average more than 100 mph on race day. Harry Hartz, who started six races and finished fourth twice, finally made it to Victory Lane as Arnold's team owner.

NOTABLE: Arnold's winning speed of 100.448 was almost 2½ mph faster than runner-up Shorty Cantlon, the second-largest disparity between first and second for a 200-lap race at Indy. The winner was rewarded with $50,300, nearly $37,000 more than Cantlon — also the biggest earnings gap between first and second. Meyer followed his 1928 win and 1929 second-place finish by coming in fourth.
