Al Unser's 1978 Triple Crown winner 

Midland Texas’ Jim Hall ended his Chaparral Can-Am program in 1970, after a series of ground-breaking race car designs, the last being the famed 2J ‘sucker car” which was outlawed. 

In 1974, Hall teamed up with Lola Cars US importer Carl Haas to field a car in the SCCA (Sports Car Club of America) Formula 5000 road racing series for open-wheel cars powered by American stock-block V-8 engines driven by Brian Redman.

The Boraxo-sponsored team used a Lola T332/Chevrolet that won the Formula 5000 championship three consecutive years – 1974, 1975, and 1976 when the series ended.  The team tried the revitalized Canadian-American Challenge Series in 1977 but Redman crashed in practice for the first race and was seriously injured.

Jim Hall next set his sights on the Indianapolis Motor Speedway in 1978 with a Lola T500-1 powered by a turbocharged Cosworth DFX engine driven by two-time Indianapolis ‘500’ winner Al Unser. Although the car was a Lola, it carried the name Chaparral for sponsor First National City Travelers Checks and the number “2” to denote Al Unser’s finish in the national points in 1977.

 The new team performed well at the first two rounds of the 1978 USAC (United States Auto Club) championship series, but Unser crashed in practice and destroyed the first T500 chassis at the third race at Texas World Speedway, and the team skipped the fourth race of the season at Trenton New Jersey. 

Al Unser qualified in fifth place for the 1978 Indianapolis 500-mile race and did not move into the race lead until lap 76, and he led three times for 121 laps and beat Tom Sneva to the checkered flag for 8.09 seconds for his third Indianapolis ‘500’ crown.

 A month later, Unser won the Schafer ‘500’ at Pocono International Raceway in the original rebuilt T500 chassis, then on Labor Day, Al and the Chaparral chassis number 2 won the California ‘500’ at Ontario Motor Speedway to become the first man to win the USAC “Triple Crown” – all three of the 500-mile races on the schedule. Although Unser won those three major races, he lost the 1978 USAC national championship by Tom Sneva by 122 points, due to the two races that Unser missed.

The restored 1978 First National City Travelers Checks Chaparral Lola now is owned by the Indianapolis Motor Speedway Foundation and was shown as part of the Unser Family Tribute at the 2018 Performance Racing Industry (PRI) trade show in Indianapolis.
