The 991 generation marked a significant evolution for the GT3 RS. Introduced in 2015, the 991.1 GT3 RS featured a new 4.0L naturally aspirated flat-six producing 500 hp, exclusively paired with a 7-speed PDK transmission. This was a departure from the previous Mezger engine cars and the manual transmissions enthusiasts loved, yet its incredible performance won over critics. The 2018 facelift to the 991.2 bumped power to 520 hp and refined the aerodynamics, further cementing its status as a top-tier track weapon.
Collectors prize the 991 GT3 RS for its raw, high-revving naturally aspirated engine in an era of increasing turbocharging. Its aggressive looks, dominated by a massive rear wing and vented fenders, are functional and iconic. While the PDK-only configuration was initially controversial, its rapid-fire shifts enable blistering lap times that a manual simply can't match. It's seen as one of the last and greatest of its kind, offering a visceral driving experience with modern capabilities.
The market for the 991 GT3 RS is mature and stable, with an average sale price over $217,000 reflecting strong demand. These cars have experienced very little depreciation from their original MSRP and have become a blue-chip collectible in the modern Porsche world. Cars with desirable options like the front-axle lift, carbon ceramic brakes (PCCB), and especially Paint to Sample (PTS) colors command significant premiums.
Buying Tips
- The 991.1 GT3's 4.0L engine had early issues; ensure any prospective car has had the updated 'G-series' engine installed by Porsche under warranty. Verify the 10-year/120,000-mile engine warranty status.
- These cars are built for the track, so a thorough inspection for signs of hard use is critical. Check for extensive rock chipping, non-original paintwork, and excessive wear on brakes and tires. A car with full-body Paint Protection Film (PPF) is a major plus.
- Key options dramatically affect value. The front-axle lift system is nearly essential for street driving. PCCB, the Sport Chrono package, and a leather interior are also highly desirable. The 991.2's optional Weissach Package, which saves 40 lbs, is the most sought-after option.
- Always request a DME report. This report shows engine operating hours and records any ignitions in the upper rev ranges. While the PDK prevents mechanical over-revs, the report still provides insight into how the car was driven.
Prices typically range from $180,000 for higher-mileage examples to over $340,000 for low-mileage, Weissach Package, or Paint to Sample cars.
