The Audi Quattro (et al.) took the world of rallying by the tender parts and squeezed. Never mind that now. I wanted to see what happens, when the street legal Audi and Lancia go head to head. Maybe you can, too? Here (it won't take more than one hour and potentially much less): Buy both cars*. Choose a snow or dirt track, maybe one that you know best or well. Buy the tyres to match. Do three laps in TT or free run, grip "real". Save the best lap. Which car was faster, and by how much? ** Should be 400 PP AUDI and 410 PP Lancia. Spoiler I did this on Chamonix East, though the Audi was at 406 PP (oil). The Lancia was 2 seconds faster. No driving aids.
