I think metals in F1 which is the most advanced racing are kind of the past. I'm sure they use titanium and magnesium, since cost really is no object. Probably some gold for heat sheilding and conducting to.

But composits and carbon fiber make up most of the car. Metal is heavy. I think even parts of the suspension are some type of carbon based material.

BMW has been using magnesium engine blocks in its new cars.
