Overview

Built by Opel in collaboration with Irmscher and Cosworth, the Ascona 400 was a continuation of the brand’s successful rally efforts in the late 1970s. Debuting in the early Group 4 era, the car used a naturally aspirated inline-4 engine and rear-wheel drive — making it a purist's machine just before the dawn of the turbocharged AWD revolution. Its greatest moment came in 1982, when Walter Röhrl drove it to the WRC Drivers’ Championship, defeating the more powerful and modern Audi Quattro in a season-long battle of strategy, consistency, and precision.

Technical Specs & Innovations

With long suspension travel and rugged engineering, the Ascona 400 excelled on rough gravel events. It lacked the technological edge of AWD rivals, but its mechanical simplicity made it reliable and adaptable across conditions.

🏆 Competitive Highlights

1982 WRC Drivers’ Champion: Walter Röhrl wins the title in a season-long duel with Audi.
1982 Monte Carlo & Ivory Coast Rallies: Röhrl wins in both tarmac and rough endurance events.
1981–1983 WRC Seasons: Consistent podium finishes by Röhrl and Jochi Kleint.

Though often seen as an underdog, the Ascona 400 outlasted and outmaneuvered its more advanced rivals through sheer reliability, disciplined driving, and intelligent strategy — marking the end of RWD at the very top of WRC competition.

Driving Characteristics

The Ascona 400 required finesse and patience. It was a momentum car — best when driven smoothly with precise inputs. Röhrl famously exploited its balanced handling and predictable cornering to overcome power deficits, especially on long gravel rallies. Though not flashy, it rewarded technical excellence and consistency over brute force.
