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.

Dangerous cars, master drivers, brute sound... Selection of best fast
passages and corners of group B vehicles. Last versions of 205T16, Audi

Audi RS Moments of Truth - 1983: quattro
Audi RS "Moments of Truth" is a series of highly stylized, dynamic
short-form documentaries that capture a moment in time -- visual, visceral
proof of the impact that technological innovation and risk-taking has had
on performance in a highly competitive world.
This film tells the story of Audi quattro and the advantage that four-wheel
drive technology afforded Audi race teams in the early 1980s on the FIA
World Rally Championship circuit. Audi driver and WRC Champion Hannu
Mikkola tells the story of his win at the 1983 1000 Lakes Rally in Finland
-- a grueling race full of big-air jumps and hairpin turns. Audi quattro
GmbH head of development Stephan Reil links the story to modern day
refinements of the quattro drivetrain bringing to life the technological
benefits of the crown gear and sport differential through dynamic track
footage of the all-new RS 5.

Rally Crashes happened in 2012 and 2013 . Car accidents because of drifts .
The production-based cars with 1.6 L direct injection turbo engine and four-wheel drive are built to
World Rally Car regulations for racing across tarmac, gravel and snow. The
power output is limited to around 300 bhp (225 kW). Current cars in the
championship include the Citroën DS3 WRC, Ford Fiesta RS WRC and Mini WRC.
The WRC was formerly held for Group A and Group B rallycars. However, due
to the increasing power, lack of reliability and a series of fatal
accidents on the 1986 season, Group B was permanently banned. Later, in
1997, the Group A cars evolved into the WRC car spec, to ease the
development of new cars and bring new makes to the competition. In 2011,
new rules were introduced to encourage more manufacturers (and privateers)
to take part, because the recent economic downturn had prompted several
manufacturers to leave the championship.
Cars in the Production Car World Rally Championship are limited to
production-based cars homologated under Group N rules. Cars in the Super
2000 World Rally Championship are homologated under Super 2000 rules. Most
cars in the Junior World Rally Championship are homologated under Super
1600 rules, but Group N and selected Group A cars can also contest the
Starting in 2013,a new category of rally cars known as Group R were
introdued as a replacement to the Group A and Group N rally categories,
with cars classified under one of six categories based on their engine
capacity and type, wheelbase, and drivetrain. As a result no cars will be
homologated under Group A and Group N regulations and instead will be
reclassified under Group R. Parallel to this, the Super 2000 and Production
Car World Championships were restructured; Super 2000 and Group N cars were
merged into a single championship known as World Rally Championship-2
alongside R4 and R5 cars, whilst the Production Car World Championship was
completely reimagined as the World Rally Championship-3 for two-wheel drive
cars complying with R1, R2 and R3 regulations.
WRC Teams and Drivers
20 different manufacturers have won a World Rally Championship event,
and a further ten have finished on the podium.
Suzuki and Subaru pulled out of the WRC at the end of the 2008
championship, both citing the economic downturn then affecting the
automotive industry for their withdrawal. Mini and Ford both pulled out of
the WRC at the end of the 2012 championship, due to a similar economic
downturn affecting the European market.
A typical WRC team will consist of about 40 people on the events, with a
further 60--100 at the team base.
Manufacturers and manufacturer-backed teams usually have two or three
drivers participating in each rally who are eligible to score points. The
total number of crews (driver and his co-driver) in the rallies varied from
47 (Monte Carlo and Mexico) to 108 (Great Britain) during the 2007
In 2012, The Ford World Rally Team and The Mini WRC Team both announced
their departure from the World Rally Championships for the 2013 season.
Volkswagen and Hyundai will make their return to the championship in 2013
and 2014, respectively.Best of Crash Rallye HD Best of Crash Rallye HD Best
