The Escalation

In 1980, the FIA set the rules for Group B, lowering homologation to 200 road cars and expanding technical freedom. The intent was innovation. What followed was acceleration.

Manufacturers interpreted the regulations differently. Lancia introduced the 037 to replace the Stratos, refining rear-wheel-drive architecture around a supercharged 2.0-liter four-cylinder producing roughly 280 horsepower. Compact, light, mechanical.

Audi entered the much bigger quattro A1. All-wheel drive, once considered excessive, began redefining traction and stage time. By 1983, the upgraded A2, driven by Hannu Mikkola and Michèle Mouton, had demonstrated its advantage.

Peugeot arrived in 1984 with the 205 T16. Audi evolved the S1 and later the S1 E2. Lancia replaced the 037 with the twincharged Delta S4 in 1985. Ford introduced the RS200. Austin Rover fielded the 6R4. Power rose. Aerodynamics grew aggressive. Complexity increased.

In 1986, following fatal accidents including the Tour de Corse, the era collapsed. Audi withdrew entirely. Peugeot switched focus. The category was cancelled at season’s end.

Group B lasted four seasons.

Its mythology endured.

This collection examines the hinge moments within it.

• Rear-wheel drive versus all-wheel drive.
• Mechanical balance versus technological escalation.
• Drivers who defined the period.
• Futures that were never realized.
