Porsche 911 GT3 RS (991)
2015–2019 (991.2 GT3 RS = 2018–2019) · Porsche 911 GT3 RS (991) — Sports Car, Flat-6, designed by Michael Mauer.
The Story
The 991 GT3 RS took the GT3’s 4.0-litre, 9,000-rpm naturally-aspirated flat-six to its hardcore extreme — and in doing so set a benchmark for road-and-track usability that few cars have ever matched. The 991.1 RS (2015) introduced the 500-PS 4.0 in full RS trim: wider track, magnesium roof, NACA-ducted bonnet, a huge fixed wing, and the famous Weissach-honed chassis. The 991.2 RS (2018) sharpened everything further — 520 PS, ball-jointed suspension, and a Nürburgring time of 6:56.4 that was just nine seconds shy of the 700-hp GT2 RS. Brutally fast yet astonishingly exploitable, it’s the last naturally-aspirated RS with a passive (non-DRS) aero package — and an instant blue-chip modern classic.

Studio Motors POV
The naturally-aspirated RS at its peak — 9,000 rpm, 520 PS, and a Nürburgring time that humbles cars with far more power. The 991.2 GT3 RS is a blue-chip modern grail; buy a low-track-time, documented car and keep it.

Studio Buyer’s Brief
The 991.2 RS (520 PS, ball-jointed suspension) is the more developed car; the 991.1 RS is the value entry to the 4.0 RS world. Verify low track time, originality and full history; the Weissach Package (where fitted) adds value. As the last passive-aero NA RS, clean, documented cars are appreciating — buy the best example you can find.

How does the 991 GT3 RS differ from the standard GT3?
The GT3 RS uses the wider Turbo bodyshell with flared arches, a larger fixed rear wing, more aggressive aerodynamics, and the Weissach Package option (weight reduction via CF components).
