Smokey Mountain II -- Mitsubishi Lancer Evolution VI Rally Car
Rally of Alps II -- Mitsubishi Lancer Evolution VII Rally Car Prototype
I don't believe there IS an Evo 6 Prototype...
In general, use the hardest tires you can while staying near the pace of the field. Never mind the hothead #1 car; he's usually on very soft tires, and will have to pit a lot. If you can hang with #2, you'll win on pit strategy, usually.
EDIT: And if I may make a suggestion, put something a little more specific than just 'Questions' in your topic line. It attracts more knowledgeable people that way.
You can't! There isn't one! The Prototype rally cars are only the newest ones that only recently started racing in the WRC, like the lastest Imprezza and the Lancer Evo7. The Evo6 would have been a 'prototype' at some point in its live, but long before GT3 came out. Maybe there was one in GT2....? I dunno.
