1919 Ballot Indianapolis - The first straight-eight Indy Car was designed by ex-Peugeot man Ernest Henry. With its twin cam engine and bucket cam followers, the Ballot should have won the Indy 500 in 1919, but weak wheels led to failures and 4th and 5th place finishes.
1931 Duesenberg Cummins Diesel Indy Racer - Powered by a Cummins 100 hp Model U diesel engine, the No.8 Duesenberg was the first car to complete the 500 mile race without stopping, using only $1.40 of fuel in the process. Driven by Dale Evans, it qualified last at 96.9 mph but finished 13th after running non-stop. While running at Daytona Beach, it became also the first diesel car to go faster than 100 miles per hour. Driven at Goodwood by Eddie Cheever and Bobby Rahal.
1952 Ferrari 375 Grant Piston Ring Special - Ferrari hoped to conquer Indy in 1952 and send four cars, one factory and three private US entries. Works driver Alberto Ascari was the only driver to qualify, but he retired after 40 laps.
1968 STP Lotus 56 Turbine Indy Car - Following ‘Mr STP’, Andy Granatelli’s own turbine Indy car – codenamed ‘Silent Sam’ – that retired just four laps from victory of the 1967 Indy 500 at the hands of Parnelli Jones, three Lotus cars were entered in the 500 mile race by Chapman, in STP colours, in 1968. Parnelli Jones drove the four-wheel drive Lotus 56 at Goodwood.
1981 Penske-Cosworth PC9B - Bobby Unser drove this Penske to his third victory at Indianapolis in 1981. The result was not final until months later due to a controversy surrounding a yellow flag overtaking infringement. Unser was reunited with the car at Goodwood.
