In racing history, one era is told and retold, mythologized, and cursed. It lasted only four years (1982–1986), but those four years changed rallying forever. It was called Group B — and today, Audi Group B rally car bricks keep its legend alive.
Some call it “the craziest category in racing history.” Others call it “a beautiful death.” Either way, one thing is certain: after Group B, there was never another Group B.
Today, we look back at this brief, crazy, glorious, and tragic history.
Read the Complete Racing Legends Pillar
Part One: What Was Group B? The Era That Inspired Audi Group B Rally Car Bricks
Group B was a rally regulation category introduced by the FIA in 1982.
Its core philosophy: fewer restrictions, encourage technological innovation.
How loose were the rules?
- Engine power: no limit
- Weight: minimum 890 kg (later raised to 960 kg)
- Turbocharging: allowed, no restrictions
- Materials: carbon fiber, Kevlar, titanium all permitted
- Aerodynamics: almost unlimited
The only real barrier: manufacturers had to build 200 production cars to homologate a model (raised to 5000 in 1985 after Lancia exploited a loophole).
In simple terms: if you dare to build it, the FIA will let you race it.
That was both the temptation and the curse of Group B.

Part Two: Why Group B? From Boring to Bonkers
In the late 1970s, rallying had become… boring.
Rally cars were based on ordinary production cars — underpowered, low-tech. Fans were leaving. Manufacturers were pulling out.
The FIA decided: loosen the restrictions, bring technology back to rallying.
Group B’s intention was good: let manufacturers showcase technology, make racing more exciting. But no one expected that once the door was opened, it could never be closed again.
Manufacturers went crazy:
- Audi: quattro all-wheel drive
- Lancia: mid-engine + AWD
- Peugeot: 205 T16, mid-engine + AWD
- Ford: RS200, designed exclusively for Group B
- MG: Metro 6R4, mid-engine V6
Horsepower went from 250 to 500, 600, even 800+. While weight stayed under 1000 kg.
Power-to-weight ratios exceeded F1 cars.
This was the prototype for what became known as the Audi’s ballistic short-wheelbase Sport Quattro S1, one of the stars of the fearsome Group B era.
Part Three: The Group B Cars — Audi Group B Rally Car Bricks Legends
Audi Sport Quattro S1
The Audi Sport Quattro S1 brick model represents the peak of quattro technology.
- Engine: 2.1L inline-five turbo
- Horsepower: 450–500 bhp (later versions)
- Features: AWD, short wheelbase, carbon-Kevlar body
- Nickname: “Shorty”
Audi rewrote rallying with quattro. The S1 was the peak of quattro technology.
Lancia Delta S4
- Engine: 1.8L inline-four twin-charged (supercharger + turbo)
- Horsepower: 480–550 bhp
- Features: mid-engine, AWD, twin-charging — 0-100-0 km/h in 7.8 seconds
The Delta S4 was Group B’s technical ceiling.
Peugeot 205 T16
- Engine: 1.8L inline-four turbo
- Horsepower: 450–550 bhp
- Features: mid-engine, AWD, extremely compact
The 205 T16 won the manufacturers’ championships in 1985 and 1986.
Ford RS200
- Engine: 2.1L inline-four turbo
- Horsepower: 450–550 bhp
- Features: mid-engine, AWD, designed exclusively for Group B
The RS200 came too late. It debuted in 1986 — the same year Group B was canceled.
MG Metro 6R4
- Engine: 3.0L V6 naturally aspirated
- Horsepower: 410 bhp
- Features: mid-engine, AWD, naturally aspirated (the only NA monster in Group B)
Among all the turbo cars, the 6R4’s V6 howl was unique.
These legends live on today as Audi Group B rally car bricks — meticulously crafted for collectors and rally fans.
Part Four: The Fatal Crashes — Group B’s Tragedy
Group B was too fast for its safety standards.
Spectator safety:
- Fans stood right next to the stage, sometimes touching distance from the cars
- No adequate run-off areas, barriers, or catch fencing
1985 Portugal Rally: a car flew into a crowd, killing 3 spectators and injuring over 30.
Driver safety:
- Roll cages were not sufficient
- Fire-resistant suits and helmets had lower standards
- Rescue facilities were inadequate
The tragedy made fans realize: Audi Group B rally car bricks are a safer way to honor these machines than risking lives.
1986 was the breaking point.
Tour de Corse: Lancia driver Henri Toivonen and his co-driver Sergio Cresto crashed while leading. Their car hit a tree and exploded. With self-sealing fuel tanks, the fire was intense. Toivonen was 29.
Toivonen’s death was the final straw.
Two weeks later, the FIA announced: from 1987, Group B would be permanently canceled.
Part Five: Why Was Group B Canceled? Three Direct Reasons
- Fatal accidents became too frequent: multiple driver and spectator deaths in 1985–1986
- Technology ran away: horsepower kept climbing, but safety couldn’t keep up
- Public pressure: media and the public began questioning whether such racing should exist
After Toivonen’s crash, the FIA barely hesitated.
In May 1986, Group B was canceled. An era stopped abruptly.
Part Six: Group B’s Legacy — Legends in Brick Model Form
Group B lasted only four years, but its influence continues today.
Technological legacy:
- AWD became the rallying standard
- Carbon fiber and Kevlar became common in racing
- Turbocharging technology advanced rapidly
Cultural legacy:
- Group B became one of the most legendary chapters in racing history
- Documentaries, films, and games keep its memory alive
- The cars became holy grails for collectors
Safety legacy:
- Group B’s tragedy directly pushed WRC safety reforms
- Spectator run-off areas, barriers, driver fire suits — all upgraded
- Later WRC became slower, safer, but also lost Group B’s magic
In one sentence: Group B will never happen again. Nor should it. But we will never forget it.
And we can keep its memory alive through Audi Group B rally car bricks — a tribute to the legends that changed rallying forever.
Part Seven: From Track to Desk — Honoring Group B
Group B has been gone for nearly 40 years. But those cars — the S1, Delta S4, 205 T16, RS200, 6R4 — live on in fans’ hearts.
You can put the spirit of Group B on your desk with an Audi Sport Quattro S1 brick model — the ultimate Audi Group B rally car bricks tribute.
It’s not in a museum. It’s by your hand.
