As a part of the complete DLC package, these cars are a welcome addition, but on their own, not at all worth eight dollars. The Red Bull X2011 Prototype '11 is certainly exciting, but the '10 prototype awarded to celebrate Vettel's championship recently (for free) is almost the same vehicle, just a little slower and a little less Batmobile-ish. The remaining cars are three Go-Kart variants that don't really add much, and a load of more or less boring Touring Cars that blend together after a while. Not worth the admission price.
