Audi Quattro Extreme towed away at the Nürburgring !
On the 1st of November 2011, yd222 recorded this Audi Quattro Extreme at
the famous gas station at the Nurburgring Nordschleife. There were some
technical problems with the car so it had to be towed away. This Audi has a
4 cylinder turbo engine (no 5 cylinder!)
that produces 450 - 500 bhp. On the Akademisches in Hockenheim this car
killed all Porsches!

Audi Quattro - Group B, the Days of Madness
Credits for this video: www.youtube.com/amjayes
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.
