Without a doubt the RS200E (evolution) was a crazy mother producing all that power from a humble 1.8L engine.
The father of rallysport till 4wd was introduced was the stratos and after 4wd it was the quattro (however the one pictured was the street version and looks very little like the actual race car)
I'm also shocked to see the Delta integrale missing since it was one of the greatest rally cars as was the celica (driven by carlos sainz). Personally i think the 2 upstarts (imprezza and evo) should be replaced with the HF integrale and the celica ST205
