Group B Rally: The Wildest Chapter in Motorsport History

The 1980s gave us many great things—Miami Vice, mullets, and Walkmans—but for petrolheads, nothing comes close to the utterly bonkers chapter in motorsport that was Group B Rally, a category in the FIA World Rally Championship that remains legendary for its unrivalled combination of power, innovation, and danger.

The Madness Begins

In 1982, the FIA decided to tear up the rulebook and replace it with…not much of a rulebook at all. Unlike previous regulations, Group B offered minimal restrictions on design and allowed advanced engineering concepts, provided manufacturers built at least 200 homologation units of the car for public sale. This sparked a race among manufacturers to produce the fastest and most technically advanced rally cars.

The result? Lightweight cars with massive turbocharged or supercharged engines capable of producing over 500 horsepower, sophisticated all-wheel-drive systems, and advanced aerodynamics that transformed the sport.

Top Rally Cars of the Group B Era

Audi Quattro S1 E2

• The Audi Quattro changed rallying forever. It introduced all-wheel drive to the sport, giving it a massive edge over the competition. The S1 E2 was the final, fire-breathing evolution, with nearly 600 horsepower and radical aerodynamics. Audi’s dominance in the early years of Group B cemented its legacy as a pioneer.

Lancia Delta S4

• Lancia went all out with the Delta S4. It combined a supercharger and turbocharger, delivering instant power with no lag and producing over 550 horsepower. The Delta S4 was brutally fast, but it’s also remembered for the tragic crash that killed Henri Toivonen and his co-driver in 1986—a turning point for Group B.

Peugeot 205 T16

• Peugeot’s 205 T16 was small but mighty. With its mid-engine layout, all-wheel drive, and over 450 horsepower, it was a game-changer. Agile and quick, it dominated the WRC in 1985 and 1986, winning back-to-back Constructors’ Championships.

Ford RS200

• Known for its striking design and balanced performance, the Ford RS200 was purpose-built for Group B. Its mid-engine layout and all-wheel drive made it competitive on a variety of terrains. However, it was plagued by development delays and a tragic accident during the 1986 Rally of Portugal that highlighted Group B's risks.

MG Metro 6R4

• The MG Metro 6R4 took a different approach with its naturally aspirated V6 engine. While it lacked the sheer horsepower of its turbocharged rivals, it was reliable and had a unique charm. Its quirky design and solid performance made it a fan favourite.

Toyota Celica Twin-Cam Turbo

• The Celica wasn’t as flashy as the others, but it was an absolute brute when it came to endurance events. It thrived in places like the Safari Rally, where the roads were less “roads” and more “endless craters filled with dust.” Rear-wheel drive, tough as nails.

The End of the Line

Group B’s greatest strength—its lack of rules—was also its fatal flaw. The cars were brutally fast but safety standards were almost non-existent, and the sport’s popularity meant enormous crowds packed the stages, often spilling onto the track. By 1986, a series of fatal accidents involving both drivers and spectators forced the FIA to act. Group B was banned for the 1987 season, replaced by the more regulated Group A.

It was a brief, brilliant, and dangerous era—a perfect storm of innovation, spectacle, and chaos. For better or worse, there’s nothing like it in motorsport today.
