The 911 GT3 RS is Porsche’s road-legal track weapon, and across four generations (996, 997, 991, 992) it has stayed true to one formula: a naturally aspirated flat-six revving to 8,500–9,000 rpm. This page profiles every GT3 RS generation against its in-game appearance in Forza Horizon 5, with notes on what to expect in Forza Horizon 6 (launching 2026-05-19, five days from today, 2026-05-14). FH6 in-game stats are still unconfirmed as of May 2026; FH5 verified numbers below are the most reliable predictor.

Quick guide: which GT3 RS, which Forza Horizon?
The 911 GT3 RS is one of Porsche’s most consistent nameplates: every generation pairs a normally aspirated flat-six with a stripped, aero-heavy chassis built for the Nürburgring. In Forza Horizon 5, four GT3 RS entries exist:
- 2016 Porsche 911 GT3 RS (991.1) — Autoshow/Wheelspin, Track Toys
- 2019 Porsche 911 GT3 RS (991.2) — Autoshow/Wheelspin, Track Toys, S2 PI 976
- 2019 Porsche 911 GT3 RS Forza Edition — Car Collection reward, Rally Monsters, S1 PI 900 (AWD-converted)
- 2023 Porsche 911 GT3 RS (992) — Series 40 Backstage reward, Track Toys, S1 PI 867
For Forza Horizon 6, the confirmed Porsche line-up so far includes the 911 Turbo S (Welcome Pack), 911 GT3, 911 GT3 R, 911 Carrera S and the 911 GT1 road car. As of 2026-05-14 (five days before launch), the 911 GT3 RS itself is unconfirmed as of May 2026 in the confirmed FH6 list — but every previous Forza Horizon entry has shipped at least one GT3 RS variant, so a return is overwhelmingly likely.
Real-world generations: 996 → 997 → 991 → 992
Every road-going GT3 RS keeps the naturally aspirated flat-six. Power has climbed by 145 PS across four generations, but the weight has only crept up by 90 kg.
| Generation | Year | Engine | Power | Torque | Weight | 0-100 km/h | Top speed |
|---|---|---|---|---|---|---|---|
| 996.2 GT3 RS | 2003–2004 | 3.6L Mezger NA | 381 PS (280 kW) | 385 N·m | 1,360 kg | 4.4 s | 306 km/h |
| 997.1 GT3 RS | 2007–2009 | 3.6L Mezger NA | 415 PS (305 kW) | 405 N·m | 1,375 kg | 4.2 s | 310 km/h |
| 997.2 GT3 RS | 2010–2011 | 3.8L Mezger NA | 450 PS (331 kW) | 430 N·m | 1,370 kg | 4.0 s | 310 km/h |
| 997 GT3 RS 4.0 | 2011 | 4.0L Mezger NA | 500 PS (368 kW) | 460 N·m | 1,360 kg | 3.5 s | 311 km/h |
| 991.1 GT3 RS | 2015–2017 | 4.0L NA | 500 PS (368 kW) | 460 N·m | 1,420 kg | 3.3 s | 310 km/h |
| 991.2 GT3 RS | 2018–2019 | 4.0L NA | 520 PS (382 kW) | 470 N·m | 1,430 kg | 3.2 s | 312 km/h |
| 992 GT3 RS | 2022–2024 | 4.0L NA | 525 PS (386 kW) | 465 N·m | 1,450 kg | 3.2 s | 296 km/h |
The 992’s lower top speed is intentional: Porsche shortened the PDK ratios and increased drag to deliver 860 kg of downforce at 285 km/h — twice as much as its 991.2-generation predecessor. It is a track car first.

Key takeaways:
- The 992 GT3 RS outscores the 991.2 in handling (8.1 vs 7.6) and braking (10.0 vs 8.2) despite sitting one class lower (S1 vs S2), mirroring its real-world downforce advantage.
- The 991.2 has a higher stock top speed (319.9 vs 309.5 kph) because its real-world gearing is taller.
- The Forza Edition is an outlier: AWD-converted, wide rally body, classified in Rally Monsters.
What to expect in Forza Horizon 6
FH6 launches 2026-05-19. The confirmed FH6 Porsche line-up so far includes the 911 Turbo S, 911 GT3, 911 GT3 R, 911 Carrera S and 911 GT1 road car. A 911 GT3 RS is unconfirmed as of May 2026.
Three reasons to still expect at least one GT3 RS at or near launch:
- Every FH game since FH2 (2014) has shipped a GT3 RS. Skipping a generation would be a deliberate departure.
- Playground has confirmed 392 of “more than 550 cars” so far. Roughly 150+ slots remain unannounced.
- The Time Attack Car Pack already includes the 911 GT3 R race car — the GT3 RS is its natural road-legal sibling.
If a GT3 RS lands in FH6, the 2023 992 variant is the most likely candidate — it’s the current showroom car, already modelled for FH5, and the FH5 992 sits at S1 867, leaving roughly 130 PI of headroom to S2 998.
FAQ
Is the Porsche 911 GT3 RS in Forza Horizon 5? Yes — four variants: the 2016 (991.1) and 2019 (991.2) from Autoshow/Wheelspin, the 2019 Forza Edition from Car Collection, and the 2023 (992) from the Series 40 Backstage Pass.
Will the Porsche 911 GT3 RS be in Forza Horizon 6? As of 2026-05-14, it is unconfirmed as of May 2026 on the confirmed FH6 car list. However, the confirmed roster already includes the 911 GT3 and 911 GT3 R, and every Forza Horizon since FH2 has shipped a GT3 RS, so a launch or post-launch addition is highly likely.
Which GT3 RS is the fastest in Forza Horizon 5? Stock, the 2019 Forza Edition has the highest top speed at 328.0 kph thanks to its AWD conversion and lighter 1,290 kg weight. Among standard variants, the 2019 991.2 (319.9 kph) edges the 2023 992 (309.5 kph), but the 992 has higher cornering grip (1.31 G) and a perfect 10.0 braking rating.
Is the 992 GT3 RS naturally aspirated? Yes. Every 911 GT3 RS from the 996 through the 992.1 uses a naturally aspirated flat-six. The 992 uses a 4.0L NA flat-six producing 525 PS at 8,500 rpm with a 9,000 rpm redline.
Why is the 992 GT3 RS slower in top speed than the 991.2? Porsche shortened the 992’s PDK gearing for track performance and increased drag to deliver 860 kg of downforce at 285 km/h. The result is a 296 km/h top speed (vs 312 for the 991.2) but a faster Nürburgring lap of 6:44.848.
How much does the 2023 Porsche 911 GT3 RS cost in Forza Horizon 5? 250,000 Credits in-game. The 2019 991.2 GT3 RS costs 255,000 Cr.
What PI class is the GT3 RS in FH5? The 2019 991.2 is S2 (976 PI), the 2023 992 is S1 (867 PI), and the 2019 Forza Edition sits exactly on the S1/S2 boundary at PI 900.
