Group B rally cars were faster than the sport could safely handle — and the result was the most dangerous era in motorsport history.
- Years active: 1982–1986
- Peak horsepower: 600+ hp
- Why it ended: Safety concerns & fatal crashes
For a few terrifying years in the 1980s, rally cars became faster than the sport could safely handle. Group B machines combined lightweight chassis, massive turbocharged engines, and almost no electronic assistance — creating some of the most dangerous cars in motorsport history.
The cars became faster than the sport itself could safely handle.
Turbochargers exploded with lag before delivering brutal waves of acceleration. Four-wheel drive systems transformed grip levels overnight. Drivers routinely described the cars as violent, unpredictable and mentally exhausting.
By 1986, the category had become so dangerous it was banned.
These were the machines that made Group B legendary.
Audi Sport Quattro S1 E2 – The 600HP Group B Monster
Driven by: Walter Röhrl, Stig Blomqvist, Michèle Mouton, Hannu Mikkola
The Audi Sport Quattro S1 looked and sounded like a weapon.
With its shortened wheelbase, giant aero components and turbocharged five-cylinder engine producing well over 500 horsepower, the S1 became one of Group B’s defining monsters.
The turbo lag was infamous. Drivers would wait for power before suddenly receiving an explosive surge that could launch the car sideways without warning.
Combined with gravel roads and massive crowds, the result was chaos.
The Quattro also revolutionised rallying by proving the superiority of four-wheel drive, permanently changing the sport forever.
Lancia Delta S4 – The Twincharged Beast of Group B
Driven by: Henri Toivonen, Markku Alén, Miki Biasion
The Lancia Delta S4 may be the most frightening rally car ever created.
Unlike rivals relying solely on turbocharging, the S4 used both a turbocharger and supercharger to eliminate lag and produce relentless acceleration.
Drivers described the car as brutally fast and incredibly difficult to predict at the limit.
The Delta S4 also became tragically linked with Group B’s downfall after Henri Toivonen and Sergio Cresto lost their lives during the 1986 Tour de Corse.
That accident effectively marked the end of the Group B era.
Lancia Delta S4 – The Twincharged Beast of Group B
Driven by: Ari Vatanen, Timo Salonen, Juha Kankkunen
The Peugeot 205 T16 was the car that truly mastered Group B.
Mid-engined, compact and devastatingly effective, the 205 T16 combined enormous power with surprising agility. Peugeot won multiple world championships with the car and dominated the later years of Group B.
Unlike some rivals, the 205 T16 felt controlled enough to exploit fully — which somehow made it even more dangerous.
When a Group B car became predictable, drivers simply pushed harder.
Ford RS200 – The Wildest Rally Car Ford Ever Built
Driven by: Stig Blomqvist, Kalle Grundel, Mark Lovell
The Ford RS200 looked futuristic and behaved accordingly.
Built specifically for Group B homologation, the RS200 featured a mid-engine layout and advanced suspension design. It was extremely capable but arrived late to the category.
Sadly, the RS200 became infamous after a crash at the 1986 Rally Portugal killed spectators, further accelerating calls to ban Group B.
Despite its short competition life, the RS200 remains one of the most legendary rally cars ever built.
MG Metro 6R4 – Britain’s Naturally Aspirated Group B Monster
Driven by: Tony Pond, Malcolm Wilson, Jimmy McRae
The Metro 6R4 was completely insane.
British manufacturer Austin Rover transformed the humble Metro hatchback into a mid-engined, four-wheel-drive rally monster powered by a naturally aspirated V6 engine.
Unlike turbocharged rivals, the 6R4 delivered instant throttle response, making it incredibly aggressive and unpredictable.
The contrast between the ordinary road-going Metro and the savage rally version only added to the car’s mythology.
Renault 5 Turbo Maxi – The Tiny Car With Brutal Power
Driven by: Jean Ragnotti, Bruno Saby
The Renault 5 Turbo Maxi embodied the madness of Group B.
Originally based on a small front-wheel-drive hatchback, Renault turned the car into a wide-bodied, mid-engined turbocharged rally machine.
The exaggerated bodywork and short wheelbase made the Maxi look permanently unstable.
It quickly became a fan favourite thanks to its violent handling style and spectacular slides.
Porsche 959 Rally – The High-Tech Supercar Built for the Desert
Driven by: René Metge, Jacky Ickx
The Porsche 959 proved that even Porsche viewed Group B as an engineering playground.
Originally intended for Group B competition before the category collapsed, the 959 featured advanced all-wheel-drive technology and futuristic electronics far beyond most road cars of the era.
The car eventually found success in the Dakar Rally, where its durability and speed became legendary.
Even by modern standards, the 959 feels technologically advanced.
Ferrari 288 GTO Evoluzione – Ferrari’s Forgotten Group B Monster
Driven by: Primarily a development prototype with no major competitive rally drivers officially associated.
The Ferrari 288 GTO Evoluzione never properly raced in Group B, but it deserves inclusion because it showed how extreme the category was becoming.
Developed as an evolution of the 288 GTO, the Evoluzione produced enormous power from a lightweight chassis and aggressive aerodynamic package.
The project indirectly inspired the Ferrari F40, which inherited much of its philosophy.
Had Group B survived longer, Ferrari likely would have entered full competition.
That alone says everything about the category’s growing intensity.
Opel Manta 400 – The Rear-Wheel-Drive Rally Icon
Driven by: Jimmy McRae, Ari Vatanen, Russell Brookes
The Opel Manta 400 represented the final era before four-wheel drive completely dominated rallying.
Rear-wheel drive, naturally aspirated and constantly sideways, the Manta required enormous driver commitment.
Compared with later Group B monsters, it looked almost simple — but that simplicity made it terrifying in its own way.
Drivers had to rely entirely on car control rather than electronic assistance.
Citroën BX 4TC – The Strange and Unpredictable Group B Challenger
Driven by: Jean-Claude Andruet, Philippe Wambergue
The Citroën BX 4TC became one of Group B’s strangest failures.
Heavy, awkward and unreliable, the BX struggled against more advanced rivals almost immediately.
But its existence perfectly captured the madness of the era. Manufacturers were willing to build virtually anything in pursuit of rally success.
Even unsuccessful Group B cars became legends because the category itself was so extreme.

Why Group B Still Fascinates Fans
Group B rallying represented pure excess.
The cars became too powerful, the roads too dangerous and the crowds too uncontrolled. Drivers often admitted they were competing beyond what felt humanly manageable.
That danger is exactly why the era still fascinates enthusiasts today.
Modern motorsport is safer, cleaner and more professional. Group B felt raw and unpredictable.
The cars moved violently, sounded brutal and demanded complete bravery from the people driving them.
It was thrilling.
It was unsustainable.
And that is exactly why Group B became immortal.
Why Was Group B Banned?
By the mid-1980s, Group B rally cars had become almost too fast for the sport to handle. Lightweight chassis, massive turbocharged engines, primitive aerodynamics, and minimal safety systems created machines capable of producing over 500 horsepower on narrow gravel roads lined with spectators.
The cars were spectacular — but they were also incredibly dangerous.
Crowds often stood just inches from the road, moving out of the way at the last possible moment as rally cars blasted through forests, mountain passes, and villages at terrifying speeds. Drivers regularly fought violent turbo lag, unpredictable handling, and near-uncontrollable acceleration on loose surfaces.
Several serious accidents during the 1986 season pushed the FIA to take action. The turning point came at the Tour de Corse rally in Corsica, where Henri Toivonen and co-driver Sergio Cresto were killed after their Lancia Delta S4 crashed and burst into flames.
The tragedy shocked the motorsport world and highlighted just how dangerous Group B had become. Following the accident, the FIA announced that Group B would be banned at the end of the 1986 season.
Group B lasted only four years, but no other era in motorsport has matched its combination of danger, speed, and chaos. These cars weren’t just machines, they were barely controllable monsters driven by people willing to risk everything.
