Jim's Audi Ur quattro page

Welcome to my homepage.

The principle interest of this site is the Audi Ur quattro

I also host a complete copy of the Isham Research website from the late Phil Payne here.

Ur is the common term when referring to the original quattro
Ur is an abbreviation of the German for 'original'

The Ur quattro comes in 3 'flavours' :-

WR	5 cylinder turbo 10 valve 200bhp normally open, lockable differentials 1981-1987(approx).
MB	5 cylinder turbo 10 valve 200bhp normally open, lockable rear differential and Torsen centre differential 1987-1990 (approx).
RR	5 cylinder turbo 20 valve 220bhp normally open, lockable rear differential and Torsen centre differential 1990-1991 (approx).

My car, shown on this site is a WR version (1985).

Details below:-

Model	Audi quattro
Year	1985
Engine Type	5 Cylinder, 2144cc Fuel Injected & Turbocharged 200bhp -WR
Colour	Tornado red

Go here for some history of work carried out on the car since I have owned it - may
be an insight into running costs.
