The Porsche 911 GT2 RS is the fastest, most powerful road-going Porsche ever to slither out of Weissach on its belly. The Renault Megane RS is 250 horsepowers' worth of Volkswagen GTI bait. Here they are together on the Nürburgring. And, go.
We don't know how many track days our 155 mph French David has over our 205 mph German Goliath, but we do know that skills often trump brute force, especially on the Hellish Green. Just ask Achilles how his heel is doing. (Hat tip to GFWilliams!)
