Group B Worship: Ford RS200 and Audi Sport Quattro - /CHRIS HARRIS ON CARS
To enter Group B in the 1980s, car makers had to build 200 road-going
examples of the car they intended to rally. These rules created some of the
most spectacular road cars of all time. I love rallying: the chance to
drive an RS200 and a Sport Quattro nearly sent me to the nut-house. Fire up

Audi Quattro - Group B, the Days of Madness

Group B was introduced by the FIA in 1982 as replacement for both Group 4
(modified grand touring) and Group 5 (touring prototypes) cars.
Group A referred to production-derived vehicles limited in terms of power,
weight, allowed technology and overall cost. The base model had to be mass
produced (5000 units/year) and had to have 4 seats. Group A was aimed at
ensuring a large number of privately-owned entries in races.
By contrast, Group B had few restrictions on technology, design and the
number of cars required for homologation to compete—200, less than other
series. Weight was kept as low as possible, high-tech materials were
permitted, and there were no restrictions on Boost, which turned out to mean almost
unlimited power. The category was aimed at car manufacturers by promising
outright competition victories and the subsequent publicity opportunities
without the need for an existing production model. There was also a Group
C, which had a similarly lax approach to chassis and engine development,
but with strict rules on overall weight and maximum fuel load.
Group B was initially a very successful concept, with many manufacturers
joining the premier World Rally Championship, and increased spectator
numbers. But the cost of competing quickly rose, and the performance of the
cars proved too much, resulting in a series of fatal crashes. As a
consequence Group B was cancelled at the end of 1986 and Group A
regulations became the standard for all cars until the advent of World
Rally Cars in 1997.
In the following years Group B found a niche in the European Rallycross
Championship, with cars such as the MG Metro 6R4 and the Ford RS200
competing as late as 1992. For 1993, the FIA replaced the Group B models
with prototypes that had to be based on existing Group A cars, but still
followed the spirit of Group B, with low weight, 4WD, high turboBoost
pressure and staggering amounts of power.
