The 2K was a Formula One-inspired ground effect Indy car designed by Briton John Barnard.
Debuting in 1979 with driver Al Unser Sr., it went on to win six races in 27 starts over three seasons.
Its greatest success came in 1980, when Johnny Rutherford drove it to victory in both the Indy 500 and PPG Indy Car World Series championship.
