France's Internets are ablaze with talk of a 500-horsepower, 500-unit limited edition of the Porsche 911 GT3 RS powered by a 4.0-liter flat six. So far all we have to work with is rumor and innuendo, but the idea is intriguing.
According to the reports, the upgraded GT3 RS would be limited to a production run of just 500 units. That sounds suspiciously like a number chosen to meet homologation rules, lending a small amount of credence to the possibility. No other details on the car have surfaced as yet, though we wouldn't expect much in the way of changes besides the additional displacement and power, as the GT3 RS is already a tautly tuned and balanced machine.
The standard GT3 RS sports a 3.8-liter naturally aspirated flat six rated at 450 horsepower. That's a heady brew, but it may not be enough to keep up with the expected competition-ready version of the Ferrari 458 Italia for GT racing. The Ferrari Italia Challenge car already unveiled is already a match or better, pumping out the stock 570 horsepower and adding in a sheaf of racing upgrades.
