Rumour has it that Porsche is working on a 500bhp limited edition of the Porsche 911 GT3.

Our French colleagues at Caradisiac are suggesting the upgraded GT3 RS would be limited to a production run of just 500 units. No further details on the car have surfaced until now, but - considering the GT3 RS is already a finely tuned car - don’t expect much in the way of changes besides the additional displacement and power.

Next month the 2010 Paris Auto Show shall take place, so we’ll see if the rumours are true…
