Porsche 911 GT2 RS tears up downtown Los Angeles

Motorsports wizard Tanner Foust of the American version of “Top Gear” took a Porsche 911 GT2 RS on the closed streets of downtown Los Angeles during the History Channel show's second season.

For those who missed it, Tanner was unimpressed after the obligatory airstrip testing in the desert heat, so he moves the evaluation to LA under the cover -- and cool weather -- of darkness. Thankfully, the cops closed some streets down for him to do his thing, which includes a drag race between the Porsche, an SRT Viper and a classic Chevy Nova.

The Porsche 911 GT2 RS is the most extreme version of the 997. It delivers 612 hp and 516 lb-ft of torque from its twin-turbocharged Boxer-six motor. Curb weight is just more than 3,000 pounds while terminal velocity is rated at 204 mph. It costs nearly a quarter-million dollars, but that's none of your concern … all examples have already been sold.
