Porsche 911 GT3 RS

Porsche has released pictures of the most intense 997 yet, the GT3 RS. Due to be released in spring next year in North America, the RS produces 415PS from its naturally-aspirated 3.6l flat-six, enough for a 0-62mph time of 4.2 seconds. Power is sent through the rear wheels only, whose surrounding shoulders widen by 43mm to accommodate the extra track. Despite this growth, weight is down over the 'regular' GT3 thanks to extra use of carbon-fiber. Standard paint finish is either black or silver, though orange and green will be available as options, complete with color-coded roll-cages.

This will be the first time in 33 years that the homologation model of the 911 will be available in North America, marking the introduction of a range of worldwide racing series.
