Four litres, six gears
The RS 4.0 closed the 997 programme with the largest naturally aspirated engine yet fitted to a production 911 and a manual gearbox as the only choice. Porsche built 600, not 500; numbered plaques verify the total.

Overview
The second-generation 997 GT3 RS already used a 3.8-litre version of the Mezger-family flat-six. For the final model, Porsche stretched capacity to four litres and restarted engine production around race-derived internal components.
The RS 4.0 arrived in 2011 with 500 PS, a six-speed manual, carbon front body panels and the most aggressive factory aero package yet fitted to a road-going 997.
Six hundred numbered cars were built. The combination of one model year, two standard exterior colours and a fixed manual drivetrain keeps the comparison set narrow, but mileage, over-rev data and repaint history still change the market result.
