Jim Hall

Hall studied engineering at the California Institute of Technology and began racing in local sports car events. He gained experience working with his brother Dick at Carroll Shelby Sport Cars in Dallas. His abilities drew international attention at the 1960 United States Grand Prix at Riverside, where he drove his own ageing Lotus-Climax to run fifth for much of the race before a differential failure late on.

At Riverside Hall was approached by California car builders Troutman and Barnes seeking funding for a new road racer. Hall backed the project and named the vehicle Chaparral. He won the Road America 500 with the Chaparral 1 before beginning design of its successor.

Hall built the first true Jim Hall Chaparral in Midland during 1962–63, simultaneously with Colin Chapman's first monocoque Formula One car. Hall and partner Hap Sharp worked with aerospace engineers to create the first successful full composite racecar monocoque. They also adopted a semi-automatic torque-converter gearbox, the first racing application of the technology.

At its debut — the October 1963 Los Angeles Times Grand Prix — Hall put the Chaparral 2A on pole over an international field including Jim Clark, Graham Hill, John Surtees, Dan Gurney, A.J. Foyt, Roger Penske, and Parnelli Jones. In 1964–65 Hall and Sharp dominated American sports car racing: Hall won the 1964 USRRC title outright and the unlimited class in 1965. In 1965 alone, Chaparrals collected 16 wins and 16 fastest laps from 22 starts. Their 1965 12 Hours of Sebring win came after qualifying 9 seconds faster than John Surtees had managed in the top factory Ferrari the previous year.

The Chaparral 2E, prepared for the inaugural Can-Am season in 1966, featured a massive articulated wing mounted on pillars above the rear deck, operated via a left-foot pedal. Sam Posey described the car's paddock arrival: "When those cars arrived on their trailers, people just stopped everything and their jaws dropped." The 2E was demonstrably the fastest car but reliability issues limited it to one win from five races. The same year, the Chaparral 2D coupe won the 1966 Nürburgring 1000 km, the first American car to win a major European road race in 40 years, and the 2F won the BOAC International 500 at Brands Hatch.

In 1970 Hall introduced the Chaparral 2J, which used a snowmobile engine to power two fans that reduced air pressure beneath the car regardless of speed — the world's first constant-downforce car. At Riverside the 2J qualified more than two seconds faster than the championship-winning McLaren M8D. The FIA banned it after other teams lobbied against it. Gordon Murray later adapted the concept for the Brabham BT46B, which won the 1978 Swedish Grand Prix — the only race it entered.

At the 1968 season-ending Las Vegas Can-Am, Hall's Chaparral was launched over a stricken McLaren at over 100 mph, causing severe knee injuries. He could walk again after six months and made a brief return in the 1970 Trans-Am season, but was unable to sustain his previous pace over a race distance.

Hall later partnered with Carl Haas to form Haas-Hall Racing, winning three consecutive Formula 5000 titles with Brian Redman and then four consecutive Can-Am titles — seven consecutive series championships from 1974 to 1980. In 1978 the team became the first (and still only) team to win IndyCar racing's Triple Crown in a single season, taking the Indianapolis 500, Pocono 500, and California 500.

Hall then commissioned designer John Barnard to build the Chaparral 2K, the first ground-effect IndyCar ("tunnel car"). Al Unser dominated the 1979 Indianapolis 500 in it before a transmission failure; Johnny Rutherford won the 1980 Indianapolis 500 and the 1980 CART PPG Indy Car World Series championship in it. Hall remained active in IndyCar with store-bought chassis until retiring from the sport after the 1996 season.

An entire wing of the Permian Basin Petroleum Museum in Midland is devoted to Hall and the Chaparral story, with seven restored race cars on permanent display. Hall was inducted into the Motorsports Hall of Fame of America (1994), the International Motorsports Hall of Fame (1997), the Texas Sports Hall of Fame (2000), the Indianapolis Motor Speedway Hall of Fame (2008), and the SCCA Hall of Fame (2012).
