Porsche is setting up a killer one-two punch for this year’s Frankfurt auto show. Alongside its range-topping 911 Turbo, the company will debut its most visceral offering, the snarling 2010 911 GT3 RS. Based on the already primal GT3, the RS gets another 15 hp from the 3.8-liter flat-six for a total of 450, or more than 118 hp per liter. A racing machine tamed for street use, the GT3 RS is hardly just about horsepower. It gets a wider track, it weighs less, and it produces more downforce than the GT3.
