The 1975 Winston 500 was an automobile race at the Alabama International Motor Speedway held on May 4, 1975.
The tenth race of 30 in the 1975 NASCAR Winston Cup Grand National season, it started 50 cars and ran 500.1 miles. It was the sixth annual late-April/early May running at Talladega and the fifth under Winston cigarettes sponsorship. The race car drivers still had to commute to the races using the same stock cars that competed in a typical weekend's race through a policy of homologation (and under their own power). This policy was in effect until roughly 1975. By 1980, NASCAR had completely stopped tracking the year model of all the vehicles and most teams did not take stock cars to the track under their own power anymore.
Talladega Superspeedway, originally known as Alabama International Motor Superspeedway (AIMS), is a motorsports complex located north of Talladega, Alabama. It is located on the former Anniston Air Force Base in the small city of Lincoln. The track is a Tri-oval and was constructed by International Speedway Corporation, a business controlled by the France Family, in the 1960s. Talladega is most known for its steep banking and the unique location of the start/finish line - located just past the exit to pit road. The track currently hosts the NASCAR series such as the Sprint Cup Series, Xfinity Series, and the Camping World Truck Series. Talladega Superspeedway is the longest NASCAR oval with a length of 2.66 miles (4.28 km), and the track at its peak had a seating capacity of 175,000 spectators.
Tickets were available for this match prior to Christmas 1974 and were sold on a first-come, first-served basis. Since the Internet didn't exist in the mid-1970s, all tickets were delivered through regular mail services. The pole for the race was won by Buddy Baker, driving the 1975 Ford Torino of Bud Moore. His primary challengers were Bobby Allison, David Pearson, Richard Petty, Dick Brooks, Dave Marcis, and Darrell Waltrip. The race lead changed 51 times among 11 drivers and was slowed by five cautions for 45 laps. There were several accidents.
Donnie Allison blew his engine while leading Lap 12 and a two-car crash ensued; among those involved were Daytona 500 winner Benny Parsons. Later Marty Robbins was involved in a fiery crash with Ramo Stott and James Hylton. The worst accident happened to Richard Petty. On Lap 141 while leading his left-front wheel bearing caught fire. He pitted while his young brother-in-law Randy Owens was fitting a hose to a pressurized water tank; the tank exploded high into the air and landed several yards from Petty, killing Owens. Another unusual event that took place at this event was Darrell Waltrip finishing in the top five despite being put out of commission with engine problems on lap 182.
Baker crowded off a last-lap bid by Pearson for the win, his first since 1973 and the first for team owner Bud Moore since 1966. The winner of the race won $28,275 ($125,847.36 when adjusted for inflation) while the last-place driver walked away with a meager $905 ($4,028.01 when adjusted for inflation).
