The Rial ARC2 was a Formula One racing car manufactured and raced by Rial Racing for the 1989 Formula One season. It was powered by a Cosworth DFR V8 engine. Its best finish was at the 1989 United States Grand Prix when Christian Danner drove it to fourth place. Development Rial Racing had run the tidy Rial ARC1, designed by Gustav Brunner, in 1988 and had scored three points with it. For 1989, a new chassis, largely based on the previous year's car and designated the ARC2, was designed by Stefan Fober, with input from Bob Bell and Martin Goodrich. The chassis was configured with double wishbone pullrod suspension, front and rear, with Koni dampers. The wheelbase of the chassis was and it had a front track of . The rear track was less, . The ARC2 was powered by the Cosworth DFR 3.5 litre V8 engine. The engine was rated as having 595 bhp with a maximum rpm of 11,000. A Lucas ignition system was used and the car ran on Goodyear tyres.

Danner failed to make the grid for the next seven races and left the
