Rumored since almost the launch of the GT2 RS, Porsche is set to reveal an even more potent version of the GT3 on April 7th.
According to the well-connected sources of TeamSpeed.com members, the new GT3 RS 4.0L Limited Edition (exact name not yet known) will sport a larger displacement flat-six. Bumping engine size by 200ccs, the 4.0-liter will make as much as 500-hp – a significant jump of 50-hp over the standard car.
Little else is known about the car, but look for a more extreme setup with an even lighter curb weight. There's even the possibility that it could use the new dual-clutch gearbox that's rumored to find its way into the next-gen GT3.
