Porsche 911 GT3 RS in Forza Horizon: Cross-Game Profile (996, 997, 991, 992)

The 911 GT3 RS is Porsche’s road-legal track weapon, and across four generations — 996, 997, 991, and 992 — it has stayed true to one formula: a naturally aspirated flat-six revving to 8,500–9,000 rpm, mounted in a stripped, aero-heavy chassis built for the Nürburgring. In Forza Horizon 5, four GT3 RS variants exist spanning three of those generations, each placed in a distinct PI bracket. With Forza Horizon 6 launching on 2026-05-19, this page profiles every GT3 RS generation against its Forza numbers: verified FH5 stats, real-world specs, and what to expect from the Forza Horizon 6 Porsche brand page when the game goes live. FH6 in-game stats remain (unconfirmed) until launch; 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 purpose-built for the Nürburgring. In Forza Horizon 5 alone, four GT3 RS entries cover nearly a decade of Porsche production: the 2016 Porsche 911 GT3 RS (991.1) in Track Toys from the Autoshow or Wheelspin; the 2019 Porsche 911 GT3 RS (991.2) in Track Toys at S2 PI 976; the 2019 Porsche 911 GT3 RS Forza Edition as a Car Collection reward in Rally Monsters at S1 PI 900 with an AWD conversion; and the 2023 Porsche 911 GT3 RS (992) unlocked via the Series 40 Backstage Pass in Track Toys at S1 PI 867.

For Forza Horizon 6, the confirmed Porsche line-up published by Playground Games includes the 911 Turbo S (Welcome Pack), the 911 GT3 R (Time Attack Car Pack), the 911 GT3, the 911 Carrera S, and the 911 GT1 road car — see the Forza Horizon 6 full car list for the full picture. As of 2026-05-14, five days before launch, the 911 GT3 RS itself is (unconfirmed) on the official FH6 roster. That said, every Forza Horizon since FH2 has shipped at least one GT3 RS variant, and with over 150 cars still unannounced, a 991 or 992 return at launch or in the first content update is overwhelmingly likely.

Real-world generations: 996 → 997 → 991 → 992

Every road-going GT3 RS keeps the naturally aspirated flat-six as its centrepiece. Power has climbed by 144 PS across four generations, but weight has crept up by only 90 kg — the RS gospel is more downforce, more revs, and just enough extra power to exploit both.

Generation	Year	Engine	Power	Torque	Weight	0–100 km/h	Top speed
996.2 GT3 RS	2003–2004	3.6L Mezger NA flat-six	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 flat-six	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 flat-six	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 flat-six	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 flat-six	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 flat-six	520 PS (382 kW)	470 N·m	1,430 kg	3.2 s	312 km/h
992 GT3 RS	2022–2024	4.0L NA flat-six	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 gear ratios and increased aerodynamic drag to deliver 860 kg of downforce at 285 km/h — “twice as much downforce as its 991.2-generation predecessor,” as Porsche’s own newsroom states. The 992 is a track car first, autobahn missile a distant second, which is why Jörg Bergmeister could post a 6:44.848 Nürburgring lap on 5 October 2022.

The Mezger engine era ended with the 997.2. From the 991.1 onward, Porsche switched to a new naturally aspirated flat-six derived from the 918 Spyder programme, gaining PDK-only transmission at the same time. The result is a measurably faster car — 3.3 s to 100 km/h vs 4.4 s in the original 996.2 — but one that divides opinion among Porsche purists who miss the sonorous Mezger revline.

Forza Horizon 5 in-game stats (verified)

Stock in-game numbers for the three headline GT3 RS variants currently in FH5. These are the game’s own physics-model readouts from Kudosprime, not Porsche’s press figures.

Stat	2019 GT3 RS (991.2)	2023 GT3 RS (992)	2019 GT3 RS FE
PI / Class	976 / S2	867 / S1	900 / S1
Power	383 kW (~520 hp)	386 kW (~518 hp)	448 kW (~601 hp)
Weight	1,430 kg	1,450 kg	1,290 kg
Drivetrain	RWD	RWD	AWD (FE swap)
Top speed	319.9 kph	309.5 kph	328.0 kph
0–97 kph	3.000 s	3.136 s	3.000 s
0–161 kph	6.900 s	7.061 s	(unconfirmed)
Lateral G	1.28	1.31	1.29
Speed rating	7.2	7.0	—

Braking	8.2	10.0	—
Offroad	5.1	5.3	—
Price	255,000 Cr	250,000 Cr	255,000 Cr

Three things stand out from these numbers. First, the 992 GT3 RS outscores the 991.2 in both handling (8.1 vs 7.6) and braking (10.0 vs 8.2) despite sitting one class lower — S1 867 versus S2 976 — which directly mirrors the real car’s aerodynamic advantage. Second, the 991.2 has the higher stock top speed (319.9 vs 309.5 kph) because Porsche gave the 991.2 taller PDK gearing; the 992 trades straight-line speed for downforce, exactly as it does in real life. Third, the Forza Edition is an outlier: converted to AWD and fitted with a rally body, it lives in Rally Monsters and is functionally a different car from the stock 991.2. The 992 GT3 RS sits exactly where you want it for the best S1-class cars in Forza Horizon bracket, while the 991.2 pushes near the fastest cars in Forza Horizon 5 conversation at stock S2.

Real-world vs in-game comparison table

	Real-world (Porsche)	FH5 in-game
2019 GT3 RS power	520 PS (382 kW)	383 kW (~520 hp)
2019 GT3 RS weight	1,430 kg	1,430 kg
2019 GT3 RS 0–100 km/h	3.2 s	3.0 s (0–97 kph)
2019 GT3 RS top speed	312 km/h	319.9 kph
2023 GT3 RS power	525 PS (386 kW)	386 kW (~518 hp)
2023 GT3 RS weight	1,450 kg	1,450 kg
2023 GT3 RS top speed	296 km/h	309.5 kph
Drivetrain	RWD	RWD (FE variant: AWD)

The 2019 and 2023 power and weight figures are essentially 1:1. The top-speed discrepancy on the 992 (296 real vs 309.5 in-game) is the most notable divergence: Forza’s physics model does not fully replicate the real car’s drag-biased setup, so the game gives the 992 back about 13 kph of top end that the real car sacrifices for downforce.

What to expect in Forza Horizon 6

FH6 launches 2026-05-19 — five days from today (2026-05-14). The confirmed Porsche line-up includes the 911 Turbo S, 911 GT3, 911 GT3 R (Time Attack Car Pack), 911 Carrera S, and 911 GT1 road car. A 911 GT3 RS is not yet on the confirmed list, so its inclusion remains (unconfirmed). 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 from an established roster pattern.
Playground has confirmed 392 of “more than 550 cars” so far. Roughly 150+ slots remain unannounced — ample room for a GT3 RS in multiple variants.
The Time Attack Car Pack already includes the 911 GT3 R race car. The GT3 RS is its natural road-legal sibling, and pairing the two is exactly how Playground has structured Porsche content in previous titles.

If a GT3 RS lands in FH6, the 2023 992 variant is the most likely candidate — it is the current showroom car, already modelled for FH5, and aligns with FH6’s focus on modern halo cars. The 991.2 is also likely given Playground’s pattern of porting popular S2-class entries. Tuning expectation based on FH5 precedent: the 992 starts at S1 867, leaving roughly 130 PI of headroom before hitting S2 998; community tunes routinely push the 991.2 past 700 hp and 350 kph in FH5, and the 992 should behave similarly given equivalent in-game power and weight. This page will update with verified FH6 figures once the game is live.

Frequently Asked Questions

Is the Porsche 911 GT3 RS in Forza Horizon 5?

Yes — four variants: the 2016 (991.1) and 2019 (991.2) from the Autoshow or Wheelspin, the 2019 Forza Edition from Car Collection rewards, 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 not on the confirmed FH6 car list, so its inclusion is (unconfirmed). 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 vs 1.28 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 aerodynamic drag to deliver 860 kg of downforce at 285 km/h. The result is a 296 km/h top speed (versus 312 km/h 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 (PI 976), the 2023 992 is S1 (PI 867), and the 2019 Forza Edition sits exactly on the S1/S2 boundary at PI 900.
