New Porsche 911 releases 620 horses

The thing to keep in mind about Porsche is that the company basically makes road-legal race cars; hence the Porsche 911 GT2 RS. This new model, limited to a production run of 500, wrings 620 horsepower out of its 3.6-liter flat six-cylinder engine. Of course, that kind of power wouldn't be possible without twin turbos and clever tuning.

That horsepower finds its real world expression in 3.4 seconds to 60 mph, a top speed of 205 mph, and a lap of the Nürburgring Nordschleife in just 7 minutes and 18 seconds.

The 911 GT2 RS was developed with a very weight conscious attitude. Porsche engineers stripped 154 pounds from it, compared with the previous 911 GT2. As one example of weight-loss engineering, Porsche used cloth straps instead of traditional interior door handles.
