The 52nd International 500 Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Thursday May 30, 1968. Bobby Unser won the first of his three Indy 500 victories (1968, 1975, 1981). 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 only nine laps, was the last front-engine car to race in the 500. This was also the first 500 won by a turbocharged engine.
For the second year in a row, one of Andy Granatelli's STP Turbine-powered machines was leading late in the race, but once again, it failed within sight of victory. [3] [4] [5] [6] 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 191 restart, and rolled to a silent and shocking halt. Unser, in the venerable piston-powered Offenhauser, inherited the lead and won the race despite gear linkage trouble.
During the month, film crews were on hand to film various action shots and stock footage of the race proceedings to be used in the 1969 film Winning , starring Paul Newman.
With 9.25 inches (23.5 cm) of precipitation in the Indianapolis area in May, the 1968 race featured the wettest month on record for the Indy 500. [7] Rain hampered practice and qualifying, but did not affect race day. This was the most recent Indy 500 scheduled for Thursday; the Uniform Monday Holiday Act was implemented in 1971 and Memorial Day became a three-day weekend (Saturday–Monday) every year. A day previously avoided, Sunday became the scheduled race day beginning in 1974.
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 (May 26) was rained out, and the track closed due to darkness with the field not yet filled to 33 cars. A special session was held Monday in order to complete the field.

The 1968 Indianapolis 500 was the second and ultimately 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 colloquially as the "Wedge Turbine," and sometimes affectionately as the "Doorstop." 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).
Another rule change dictated that cars were required to conduct three mandatory pit stops, up from two that were required from 1965 to 1967.
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.
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 four-lap average speed of 171.559 mph (276.1 km/h).
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 was the lone qualifier at 164.144 mph (264.2 km/h), 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.
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. [8] Many cars waved off, and Mel Kenyon, at 165.191 mph (265.8 km/h), was the fastest of the day.
After qualifying, Ronnie Bucknum's car was disqualified for being twenty pounds (9 kg) underweight.
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. [9]
For the first time since 1952, time trials were pushed into a fifth day. [9] 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. [10] 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 led 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 lost 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 tangled 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 into the turn four grass trying to avoid the accident. Rutherford was out, but McElreath limped back to the pits where his crew repaired the nosecone.
When Bobby Unser made his last pit stop on lap 166, his gearshift linkage was broken, and the car was stuck in high gear. As he slowly left his pit, struggling to accelerate back to racing speed, both Leonard and Ruby passed him. Leonard now led in the Turbine. Ruby was up to second, but moments later on lap 178, Ruby was back in the pits with a faulty ignition coil. His crew was able to replace the coil, but the six-minute pit stop dropped him out of contention for the win.
With 19 laps to go, Joe Leonard led, with Bobby Unser back up to second. Carl Williams crashed on the backstretch, triggering a fire which brought out the yellow light. Under the caution, Leonard led, with Bobby Unser second, and Dan Gurney in third. For a brief moment, a controversy started brewing as Art Pollard (teammate to Joe Leonard), who was a couple laps down, was not keeping up with the caution pace. As a result, Bobby Unser was stuck behind him, and losing track position to Leonard.
After the cleanup, the green flag was given to the field at the start of lap 192. 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 over the final nine laps to win his first Indianapolis 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. Unlike the 1967 race, the Turbine did not run away from the field in 1968. Bobby Unser led the most laps in the Offenhauser, but Joe Leonard spent most of the day on Unser's tail, in the top three. Graham Hill ran in the top five, but complained that he lacked speed down the long straights, and was running 4th when he wrecked. Art Pollard, in the third Turbine, spent most of the day in the top ten before the car quit, but was never really a factor for the win.

The race was carried in the United States on ABC's Wide World of Sports . The broadcast was supposed to air on Saturday, June 8 but was postponed a week to Saturday June 15 due to the funeral that day of Senator Robert F. Kennedy. Jim McKay anchored the broadcast with Rodger Ward as analyst, and Chris Economaki as a pit reporter..
The race was shown live on MCA closed-circuit television in approximately 175 theaters across the United States. [17] [18] Charlie Brockman served as anchor.
The 49th International 500-Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Monday, May 31, 1965.
The Lotus 56 was a gas turbine-powered four-wheel-driven racing car, designed by Maurice Philippe as Team Lotus's STP-backed entry in the 1968 Indianapolis 500. All three cars entered and retired from the race with Joe Leonard's car expiring while leading just eight laps from the finish.
The 54th 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Saturday, May 30, 1970.
The 55th 500 Mile International Sweepstakes was a motor race held at the Indianapolis Motor Speedway in Speedway, Indiana on Saturday, May 29, 1971. Al Unser Sr. won for the second consecutive year, dominating most of the race. Unser became the fourth driver to win the Indy 500 in back-to-back years, and it was his second of a record-tying four Indy victories.
The 56th 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana, on Saturday, May 27, 1972. The race is notable in that for the first time, the cars were permitted bolt-on wings, and speeds climbed dramatically. Bobby Unser won the pole position at a then-remarkable speed of 195.940 mph (315.3 km/h) for four laps, breaking Peter Revson's track record of 178.696 mph (287.6 km/h) from 1971 by 17.244 mph (27.8 km/h) – the largest one-year track record increase in Indy history. The race average speed of 162.962 mph (262.3 km/h) was also a new record, which stood until 1984.
The 59th 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday, May 25, 1975. A. J.

The 61st 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana, on Sunday, May 29, 1977. Considered one of the most historically significant editions of the Indianapolis 500, several sidebar stories complemented the unprecedented accomplishment of race winner A. J. Foyt. Foyt became the first driver to win the Indianapolis 500 four times. As of 2024, Foyt's record has been tied by Al Unser Sr., Rick Mears and Hélio Castroneves, but still stands as an Indy 500 record. Foyt's victory is also the last time the winning car was built entirely within the United States.
The 62nd 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday, May 28, 1978. Danny Ongais dominated the early stages of the race but eventually dropped out with a blown engine. Al Unser Sr. dominated the second half, and held a large lead late in the race. However, Unser bent the front wing of his Lola during a pit stop on lap 180, causing his handling to go away over the final twenty laps. Second place Tom Sneva charged to catch Unser's crippled Lola but came up 8 seconds short at the finish line – the second-closest finish in Indy history to that point. Unser held off the challenge, and became a three-time winner of the 500. It was Al Unser's third Indy victory in the decade of the 1970s, and the fifth of nine overall victories by the Unser family.

It was also Roger Penske's second Indy 500 victory as a car owner.
The 53rd International 500 Mile Sweepstakes was an auto race held at the Indianapolis Motor Speedway in Speedway, Indiana on Friday, May 30, 1969. It was the third round of the 1969 USAC Championship Car season. Polesitter A. J. Foyt led the race in the early stages, looking to become the first four-time winner of the 500. Near the halfway point, however, a lengthy pit stop to repair a broken manifold put him many laps down. Despite a hard-charging run towards the end, he wound up managing only an eighth-place finish, 19 laps down. Lloyd Ruby, a driver with a hard-luck reputation at the Speedway, was leading the race just after the midpoint. During a pit stop, he pulled away with the fueling hose still attached, ripped a hole in the fuel tank, and was out of the race. The incident put Mario Andretti in the lead for rest of the way.
The 51st International 500 Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana, over two days, Tuesday May 30 and Wednesday May 31, 1967.

With three laps to go, however, Jones coasted to a stop when a $6 transmission bearing failed. A. J. Foyt assumed the lead, and weaved his way through a pileup on the final lap, to win his third Indy 500 victory.
The 47th International 500-Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Thursday, May 30, 1963. Rufus Parnelli Jones took his only Indy 500 win. This win was controversial because his car spewed oil from a cracked overflow tank for many laps, which allegedly caused at least one driver to spin and crash. USAC officials put off black-flagging Jones after car owner J. C. Agajanian ran down pit lane and convinced them that the oil leak was below the level of a known crack and would not leak any further. Lotus owner Colin Chapman, whose English-built, rear-engined Lotus-Ford finished second in the hands of Scotsman Jim Clark, accused USAC officials of being biased in favor of the American driver and car.

Unser was subsequently issued a one-position penalty. The next morning, the official race results were posted, and Unser was dropped to second place. Andretti was elevated to first place and declared the race winner.
