The Porsche 997.2 GT3 RS 4.0 (2011) is the halo car of the entire 997 generation and, for many, the high point of the driver-focused 911. A one-year, 600-unit run-out special powered by the largest and most powerful naturally aspirated flat-six Porsche had ever put in a road 911.

Highlights
- RSR-derived crankshaft with increased stroke to reach 4.0 litres
- Titanium connecting rods, carbon-fibre front fenders and bonnet
- Front “flics” (dive planes), bespoke PASM damping, stiffer springs
- Shorter-ratio manual gearbox
- The last and most extreme naturally aspirated road-going Mezger 911
Common Issues
Mechanically it is the robust Mezger core. The real risks are market and provenance: confirm a numbers-matching engine, no over-revs, documented history, and undamaged carbon panels and original aero. Collector cars that have been tracked hard need extra scrutiny.
Market Analysis (as of 2025)
- Entry (higher mileage, still rare): CHF 550,000–650,000
- Exceptional / low mileage: CHF 700,000–850,000+
One of the few modern 911s that is a blue-chip appreciating asset, rarer than a Carrera GT or 918 in some respects.
FAQ
Why so special?
Last NA Mezger, largest NA flat-six in a road 911 at launch, only 600 built, run-out halo of the 997. Near-universal agreement as the peak driver-focused 911.
Manual only?
Yes, 6-speed manual exclusively.
Collector Notes
Numbers-matching, documented over-rev history, original paint and carbon panels are everything at this value level. PTS examples are effectively priceless.
