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.
Audi 200 Quattro
Here's some clips from the Audi's 1987 group-A rally car, 200 Quattro. Although large as a battleship, it still scored some good results: Rohrl was 3rd in Monte '87, Mikkola won the Safari '87 and was 3rd in Acropolis rally. In 1988 Armin Schwarz drow himself 5th in RAC rally with 200 Quattro.

Ministry of Dirt - Rallycar rebuild timelapse
This is Ministry Of Dirt rebuilding the car after a 140kph roll ( 7 times) at the Whangarei International Rally 2010,
Just shy of 300 hours to rebuild the car . This gives people more of an insight to what is involved in getting a car ready for a rally and the amount of hours that actually go into repairing/ preparing a rallycar.
Unfortunately in the next rally Piran Pigneguy and Malcolm Reid rolled on stage 2 in 4th gear, dropping down to 40th overall, before regaining back up to 20th by the end of day 1
Big thanks to the Ministry Of Dirt team in getting the car ready in 3 week.
Also big thanks to Nick and Josh from Pimppalacecustoms for producing the video
