The 991 was the first all-new 911 platform since the 996, replacing nearly every component of the 997. A longer wheelbase, aluminum-steel hybrid construction, and electromechanical steering marked a decisive shift toward a larger, more refined GT-adjacent 911. Produced from 2012 to 2019, the 991 bridged two eras within itself — the 991.1 kept naturally aspirated flat-sixes for its Carreras, while the 991.2 introduced twin-turbocharged 3.0L engines across the Carrera range.
That mid-cycle change is the single most important fact driving 991 collector dynamics. The 991.1 Carrera S is the last naturally aspirated 911 Carrera Porsche ever built — a detail that was widely debated at launch and is now the central argument for their appreciation. At the same time, the 991 generation delivered some of the most significant GT cars in modern 911 history: the 991.1 GT3 RS 4.0, 991.2 GT3 (with the return of the manual), GT3 Touring, GT2 RS, the 991 R, and the 991.2 Speedster — every one of which trades at or above MSRP today.
Under the skin the 991 is modern enough to daily-drive, comfortable across long distances, and mechanically more robust than the IMS-era 996/997.1 cars. It is the generation where the 911 became a credible grand tourer without giving up the GT3 lineage — and where the last chapter of NA flat-six 911 motoring closed.
991.1 NA 3.4/3.8; 991.2 twin-turbo 3.0. 991.1 manual coupes are the collector pick — last NA 911 Carrera.
AWD variant. Trades at a modest discount to RWD; 991.2 widebody shared with Turbo.
Reintroduced wraparound rear glass. Enthusiast favorite; manual Targa 4S GTS is especially sought-after.
3.8L twin-turbo; Turbo S at 580 hp (991.2). Daily-usable supercar performance; strong and steady values.
3.8L NA, PDK only. Early engine recall overshadowed launch; sorted examples now well-regarded.
4.0L NA, 9,000 rpm, return of the 6-speed manual option. Touring package adds deleted wing. Blue-chip.
4.0L NA, PDK only. The first water-cooled RS with a 4.0; trades consistently above MSRP.
Refined aero and chassis over 991.1 RS; weissach package available. Blue-chip.
700 hp, set the production-car Nürburgring record at launch. Weissach package cars command the largest premium.
991 produced. NA 4.0 GT3 engine in a lightweight body with a 6-speed manual only. Traded at multiples of MSRP immediately; still firmly six-figure premium.
1,948 produced. Last NA 4.0 in a Carrera-bodied car. Manual only; heritage design package the collector pick.
Lightweight option-focused spec on the base Carrera. Manual-friendly and increasingly appreciated as a driver's 991.2.
No 991-generation Sport Classic was built; the nameplate returned on the 992. Included here only to avoid confusion with the 997 Sport Classic.
The 991.1 (2012–2015) Carreras use naturally aspirated 3.4L and 3.8L flat-sixes; the 991.2 (2016–2019) replaced them with a 3.0L twin-turbocharged flat-six across the Carrera range. GT cars (GT3, GT3 RS, GT2 RS) retained NA engines across both phases. The 991.2 also brought revised styling, active aero on some trims, and — for the GT3 — the return of the 6-speed manual.
Limited-run 991 variants (911 R, Speedster, GT3 RS, GT2 RS, GT3 Touring) have traded at or above MSRP since delivery and have appreciated meaningfully. Standard Carreras are not collector cars in the traditional sense, but 991.1 manual Carrera S coupes have firmed up as the last NA 911 Carrera. As with any collector purchase, documentation, option spec, and buying at a fair entry price determine returns.
Only 991 examples were produced, all manual, all with the 4.0L GT3 RS engine in a lightweight Carrera-style body with no rear wing. Porsche positioned the R as a driver's special, and the extremely limited run combined with the manual-only specification caused values to multiple several times over MSRP within months of launch. The R remains one of the strongest-performing modern Porsche collector cars.
Both are offered as no-cost options. The 6-speed manual tends to command a modest premium in the collector market and is preferred by purists, while PDK cars are faster on track and more livable in traffic. Touring package GT3s — which delete the fixed rear wing — were manual-only on the 991.2 and trade at the strongest premiums of any 991 GT3 configuration.
Clean 991.1 Carrera coupes typically trade in the $60k–$90k range, with Carrera S manuals firming toward the top of that band. 991.2 Carreras sit $70k–$110k. Turbo S runs $140k–$200k depending on phase. 991.2 GT3 is $180k–$260k, GT3 Touring $220k–$320k, GT3 RS $250k–$400k+, GT2 RS $450k–$600k+. The 911 R and Speedster sit at $450k–$700k+.

The 991.1 Carrera S is the last naturally aspirated 911 Carrera, a point of historical significance for a model line defined by its NA flat-six character. The 991.2 turbocharged Carreras are objectively faster and more efficient but lack the linear throttle response and top-end character of the NA engines. That preference has translated into firmer 991.1 values for manual coupes with desirable specs.
The 991.2 GT2 RS is the most powerful factory 911 ever built at its launch — 700 hp from a twin-turbocharged 3.8L flat-six, RWD only, with a Weissach lightweight package option. At release it set the production-car Nürburgring lap record. It is the apex of the 991 generation and trades consistently at a significant premium over MSRP; Weissach-package cars command the strongest prices.
The 991.2 Speedster is limited to 1,948 units, uses the NA 4.0L GT3 engine, and is manual-only — the last naturally aspirated Carrera-bodied Porsche road car. It has traded at or above MSRP since delivery and is widely treated as a blue-chip modern Porsche. Heritage Design Package cars carry a modest additional premium.
For outright collectibility: 911 R, GT3 Touring, Speedster, or GT2 RS — all limited-production and trading firmly above MSRP. For a usable collector car with appreciation potential: a clean 991.1 Carrera S manual coupe or a 991.2 Carrera T. For long-term blue-chip exposure with track credibility: 991.2 GT3 RS or GT3 Touring manual. The right answer depends on intended use and budget.
Verify full Porsche service history, check for evidence of the 991.1 GT3 engine recall (replacement engines were installed on affected cars — this is not a negative), inspect PDK software updates, review PCCB brake wear if equipped (replacement is a five-figure cost), confirm no track use on cars that are not GT-spec, and verify the PPF and paint originality. Option sheet and window sticker matter for resale.
The 991 is the generation where the collector case separates sharply by variant. Limited-run specials — 911 R, Speedster, GT3 Touring, GT2 RS, and GT3 RS — are already blue-chip and have shown consistent above-MSRP trading. Standard 991.1 Carrera S manual coupes have firmed meaningfully as the last naturally aspirated 911 Carrera; 991.2 Carreras remain primarily a driver's-car proposition. Turbo S values have been stable. The 991 is the first water-cooled 911 generation where specific variants command genuine collector premiums across the board.
