The 52nd International 500 Mile Sweepstakes was held at the Indianapolis Motor Speedway on Thursday May 30, 1968. For the second year in a row, Andy Granatelli's STP Turbine-powered machine dominates the race, but once again, failed within sight of victory.
On lap 174 Lloyd Ruby's engine misfired allowing Joe Leonard to take the lead in the Lotus 56 turbine. Leonard, however, suffered a flameout on the lap 190 restart, and rolled to a silent and shocking halt. Bobby Unser in the venerable piston-powered Offenhauser, inherited the lead, and despite gearbox trouble, went on to win his first of three Indy 500 victories.
This was the final Indianapolis 500 to feature a front-engined car in the starting field. Of the 33 cars, 32 were rear-engined machines (including three turbines). Jim Hurtubise's entry, which dropped out after nine laps, was the last front-engine car to race in the 500. It was also the first 500 won by a turbocharged engine.

Time trials was scheduled for four days, but for the first time under the current schedule format, qualifying was carried over into a fifth day. Most of Bump Day was rained out, and the track closed due to darkness without the field yet filled to 33 cars. A special session was held Monday in order to complete the field.
- The 500 Festival Parade was held Tuesday night, May 28.
Practice and time trials
The 1968 Indianapolis 500 was the second and eventually the final year of participation by the controversial STP Granatelli Turbine machines. For 1968, the Pratt & Whitney turbine engine was installed in the Lotus 56 chassis, often known affectionately as the "Wedge Turbine." In a veiled effort to curtail the turbine's power output, USAC had imposed revised regulations regarding the maximum annulus inlet (reduced from 23.999 in² to 15.999 in²).
Mike Spence was fatally injured after a crash in turn one on May 7. A tire broke off his Lotus "Wedge" Turbine and struck him in the head. He died of his injuries a few hours after the accident after being taken to the hospital. Spence's death came one month after Jim Clark's at Hockenheim. Clark was scheduled to drive one of the Lotus Wedge Turbines at Indy.
Pole Day Time trials - Saturday May 18
Graham Hill the 1966 winner in the #70 STP Turbine was first to qualify, and set a new qualifying record. Later, his STP Lotus 56 teammate Joe Leonard in #60 won the pole position with a speed of 171.559 mph (276.097 km/h).
Second Day time trials - Sunday May 19
Rain kept cars off the track most of the day. Only two cars were able to make an attempt, and only one was run to completion. At 5:45 p.m., the track was finally opened for qualifications, and Jochen Rindt (164.144 mph) was the lone qualifier, while Denny Hulme waved off as the 6 o'clock gun went off.
At the conclusion of the first weekend of time trials, the field was filled to 16 cars.
Third Day time trials - Saturday May 25
Sixteen cars made a total of 24 attempts, and filled the field to 26 cars. High winds kept some cars off the track, and speeds were down from the previous weekend. Many cars waved off, and Mel Kenyon (165.191 mph) was the fastest car of the day.
After qualifying, Ronnie Bucknum's car was disqualified for being 20 pounds underweight.
Fourth day time trials - Sunday May 26
With the field filled to 25 cars (eight spots open), rain kept the cars off the track until late in the day. The final scheduled day of time trials ("Bump Day") was almost a complete wash out. The traditional 6 o'clock closing time came and went, and the track was still wet. Track crews continued to work, and the track opened for practice at 6:55 p.m. After the mandatory 30-minute practice session, the track opened for time trials at 7:31 p.m.
With overcast skies and darkness looming, three cars made attempts. Bill Puterbaugh and Bill Cheesbourg completed runs, while Bobby Johns spun on his second warm up lap. At that time, officials deemed the conditions unsafe due to darkness, and postponed the remainder of qualifying until Monday morning.
Time trials - Monday May 27
For the first time since 1952, time trials were pushed into a fifth day. Officials ruled that all 25 cars that were in the starting field at 6 p.m. Sunday May 26 were "locked in" and could not be bumped. In addition, all cars that were in line to qualify Sunday evening at 7:54 p.m. were eligible to make one qualifying attempt on Monday. Only cars that qualified after 6 p.m. on Sunday evening were subject to bumping (including Puterbaugh and Cheesbourg).
Ronnie Bucknum was reinstated to the field when it was determined that during his inspection, the scale used to weight the car was defective. With Bucknum's car back in the field, only seven spots were now available.
Though rain hampered the day, the qualifying was successfully completed on Monday. A frantic session saw two crashes (Bob Hurt and Rick Muther). Eighteen cars took to the track to fill the seven open spots. Both Puterbaugh and Cheesebourg were bumped, and Mike Mosley was the fastest of the day. Jim Hurtubise qualified his front-engined Mallard for 30th starting position. It would be the final front-engined car to qualify for the Indy 500.
At the drop of the green flag, Joe Leonard in the #60 STP Turbine took the lead, with Bobby Unser in second and Roger McCluskey up to third at the end of lap one. A fast pace was set over the first 100 miles, with no yellow caution lights. Bobby Unser took the lead for the first time on lap 8, and lead most of the first half.
After only nine laps, Jim Hurtubise in the front-engined PepsiCo Frito-lay special had burned a piston, and was out, finishing 30th, the final front-engined "roadster" to race at lap at the 500. Also in the pits was Mario Andretti, who dropped out with a bad piston. Moments later, he hopped into the car of his teammate Larry Dickson, but that was also short-lived. That car also suffered a broken piston after 24 laps.
On lap 41, the caution flag flew for the first time. Al Unser, Sr. made a routine pit stop, but a fire broke out in the turbocharger. He was able to return to the race, but after only one lap, he lost a wheel and hit the wall in turn one. Arnie Knepper and Gary Bettenhausen were also involved. After 200 miles (320 km), defending champion A.J. Foyt was out with a blown engine.
On lap 110, Graham Hill loses a wheel and smashed into the turn two wall, which brought out the second caution. It was the first of the three Granatelli Turbines to drop out of the race. On the restart, Bobby Unser took the lead, blowing by Joe Leonard, showing the traditional piston-powered engines were still a match for the powerful turbines.
On lap 127, Mel Kenyon and rookie Billy Vukovich II tangle in turn four. Both were able to re-enter the race, but Johnny Rutherford, while trying to slow down, was rear-ended by Jim McElreath. Mike Mosley also spun in turn four trying to avoid the accident.
When Bobby Unser made his last pit stop, his car was stuck in high gear. As he left his pit struggling to reach racing speed, both Leonard and Ruby passed him. Leonard now lead, but Ruby was out of contention with a faulty ignition coil.
With 19 laps to go, Joe Leonard led, with Bobby Unser second. Carl Williams crashed on the backstretch, triggering a fire which brought out the yellow light. Under the caution, Leonard led, with Bobby Unser and Dan Gurney nose-to-tail. After the cleanup, the green flag was given on lap 191. At that instant, both leader Joe Leonard and his teammate Art Pollard hesitated and instantly slowed with identical snapped fuel pump drive shafts. The turbine engines again failed in sight of the finish, stunning the racing fraternity. Bobby Unser swept by into the lead with Dan Gurney inheriting second place. With a nearly full-lap lead, Unser cruised the final nine laps to win his first 500.
Cars using Goodyear tires swept the top four positions, and Goodyear won their second 500 in row. Officials allowed the top five cars to finish the full 500 miles, then flagged the rest of the field off the track. This would be the final 500 in which finishers were named to the prestigious Champion Spark Plug 100 mph Club.

The broadcast had an estimated 100 million listeners worldwide.
Collins greeted numerous guests in the booth during the race. Among those who stopped by were Chuck Stevenson, Sam Hanks, J. C. Agajanian, former (and future) radio analyst Fred Agabashian, Duke Nalon, Pete DePaolo, Henry Banks, Tom Binford, Johnnie Parsons, and Johnny Boyd. Indiana Senator Vance Hartke visited the booth, escorting a delegation that indluded Secretary of Transportation Alan Boyd. FCC chairman Rosel H. Hyde, Utah Senator Frank Moss, and Jack Kauffmann (The Washington Star). Senator Birch Bayh also visited the booth, accompanied by his teenage son, future senator Evan Bayh, who was attending his first race.
