Rial is a German producer of light alloy wheels and rims,[1] and was a Formula One constructor competing in the 1988 and 1989 seasons.

[5] Andrea de Cesaris, with Marlboro sponsorship was hired to drive the car, which proved strong in testing due to a small fuel tank.

Continuous mechanical problems and the fuel tank contributed to a six-race string of retirements, de Cesaris finishing the season classified 8th in Australia.

[7] Rial expanded to two cars ahead of the 1989 season, and with de Cesaris moving to Dallara, German drivers Christian Danner and Volker Weidler were hired to drive the ARC2.

Weidler meanwhile had failed to pre-qualify for any race so far in the season,[5] and following Danner's 8th-place finish in Canada in what was to be Rial's final race start, neither driver qualified for the following Grands Prix, despite both Rial cars being allowed to enter qualifying following the changing of pre-qualifying rankings after the British Grand Prix.

[4] Gregor Foitek was brought in for Spain, but a rear wing breakage during qualifying caused an accident destroying his car, and he immediately left the team.
