When I think of homologation specials, there are all sorts of models that instantly pop into my head. Of course, being an Audi fan, the Sport Quattro is a great example of the insane Group B era. Of course, Group C spawned a whole series of special cars, from the RS200 and Lancia 037 to the Porsche 959. There’s the special 924 Carrera GTS, as well – a car few remember outside of Porsche circles, and one that’s often forgotten even by them. Then there’s the great period of DTM specials – the “Evolutions†of the M3, 190E and V8 quattro that proved Darwin was right, and we just looked at the later 80 Competition. Of course, you can go back even further and look at one of the most special cars ever created – the original Ferrari GTO – to see a very special homologation of a race car. But outside of the big headlines, there are plenty of small production run cars that were created to jump through loopholes, and returning to my original Group B example, we can see one neat car that was created in order to run in World Rally.
