Re: limited edition 340hp audi from the '80's??? (matt007)
Could these be the specs you meant?: 306 bhp at 6700 rpm and had a maximum torque is 2 46 lb-ft at 3700 rpm. If so, you are talking about the elusive "Sport Quattro."
The primary distinguishing feature is the car is much shorter than the normal quattro coupe. The wheel base is shortened by 320mm, with the overall length being reduced by 240mm. The wheelbase was shortened for three reasons: to lose weight, to improve weight distribution and to reduce the polar moment of inertia. A less noticabel feature are the angles of the windshield and roofline. On the sport quattro, the front end and doors from the 4000 sedan are used which places the
windshield in a more upright position. The difference in this angle is only 2 degrees, but quite noticable. Almost all the body panels are custom made for the sport quattro with the exception of the metal doors(4000 sedan) and the Kevlar trunk lid(quattro coupe). The hood is made from fiberglass and the roof, fenders, bumpers and front and rear aprons are made of a Kevlar-GRP composite.
The sport quattro marked the introduction of Audi's 20-valve turbocharged engine into a road- going car. It has a bore of 79.3mm and a stroke of 86.4mm yielding a displacement of 2133cc. It used a compression ratio of 8.0:1. The intake valves have a diameter of 32mm and the exhaust valves are sized at 28mm. A large KKK-K27 turbocharger with a maximum boost pressure of 17.4 psi is used. The engine management is the Bosch LH motronic all-electronic fuel injection along with Bosch digital electronic ignition. The street engine produced 306 bhp at 6700 rpm and had a maximum torque is 2 46 lb-ft at 3700 rpm.
There were 214 cars produced between February 1984 and January 1986 which satisfied the motorsport homogulation requirements (a minimum of 200 units for Group B). Chassis numbers has the prefix SQ and ran from SQ85EA905001 to SQ85EA905214. Of the 214 produced, 164 were sold to customers, 19 were experimental and never left the factory, 20 were allocated to the motorsport department, 5 were used as spare parts and the remaining 6 are presumed to remain
within the company. The 5 spare parts cars were rebuilt in 1988 and sold to customers.
According to the production listing the the book by Jurgen Lewendowski, there are 10 sport quattros in the US, 6 red, 2 white and 2 green. There are probably a few more in the US than just these. I know that there are at least 3 white ones in the US along with a blue one which isn't listed.
Audi quoted the following performance figures for the sport quattro
0-100 kph (62 MPH): 4.9 seconds
Top Speed : 155 mph
Fuel consumption at 75 mph was 22.5 mpg
