Thursday 30th May 1968
On lap 174 of the Indianapolis 500 Lloyd Ruby’s engine misfired allowing Joe Leonard’s STP Lotus turbine into the lead. Leonard’s leading Lotus flamed out on a lap 190 restart and rolled to a silent halt. Bobby Unser sailed by to win. Jim Hurtubise’s entry, which dropped out after nine laps, was the last front-engine car to race in the 500.
