Porsche 911 Turbo S 991
Flat-six thunder in a shape that has never needed to change.
The Porsche 911 Turbo S (991) is one of the most instantly recognizable super-sport coupes in the Forza Horizon series, a car that fans reach for when they want a blend of raw straight-line fury and everyday drivability wrapped in that unmistakable rear-engine silhouette. It slots into the S2 class in Forza Horizon 5, where it competes against hypercars and track-bred machines, yet it still feels like a 911—punchy, communicative, and endlessly fun to fling through corners at speed.
For many players, the 991 Turbo S represents the sweet spot of the Porsche lineup: more power than the Carrera S, more practicality than the GT3 RS, and a tuning ceiling that lets you push it into genuinely competitive territory without losing the character that makes it a 911 in the first place.

Lore & Background
The 991 generation of the 911 Turbo S arrived in 2013 as Porsche's statement that the rear-engine, air-cooled-era icon could still punch above its weight in a world of V8s and V10s. By dropping the old 3.6-litre unit for a 3.8-litre twin-turbo flat-six, Porsche gained a broad, linear torque curve that makes the car feel effortless from a standing start yet still revs with a vocal, raspy bark that no V8 can replicate. In the Forza Horizon open worlds, that character translates beautifully: the car wants to be driven, not just pointed, and its weight distribution rewards a driver who respects the tail.
Within the franchise's narrative, the 991 Turbo S is never a one-off trophy car. It shows up in the hands of everyday players grinding through the Horizon Festival, parked on a dirt overlook in the Australian outback or sliding through wet Scottish heather. It is the car you buy when you have saved up enough credits and you want something that feels like a Porsche should feel—precise, a little aloof, and absolutely relentless once the turbos spool.
Fans often pair it with a deep, metallic blue or the classic GT Silver, and the community has a soft spot for the subtle rear wing and the way the taillights glow in the Horizon 5 sunset. It is, in the collective imagination of the player base, the car you drive when the music is good and the road is empty.
Reader's Guide
Full model: Porsche 911 Turbo S (991), 2013–2015, S2 class (Forza Horizon 5). Stock, the car makes roughly 550 hp from its 3.8-litre twin-turbo flat-six, sits near 3,700 lb, and carries a handling rating that puts it firmly in the fast-but-not-hypercar bracket—quick to 60 in about 3.2 seconds, top speed just over 200 mph, and a cornering feel that is more communicative than raw grip.
Tuning levers are generous. You can swap the stock engine for higher-output units, bolt on a larger turbo or a supercharger, and move to a shorter-ratio or higher-ratio transmission depending on whether you want launch speed or top-end. Suspension, brakes, and tyre compounds are all upgradeable, and body kits shift the aero balance. The trade-off is weight: every bolt-on adds mass, and past a certain point the 911's rear-engine balance starts to fight you, especially in tight, technical sections.
Build philosophy: treat it as a driver's car first—modest turbo bump, stiffer suspension, sticky rubber—and let the flat-six do the talking rather than masking it under a mountain of horsepower.
Did You Know?
- The PDK dual-clutch transmission gives the Turbo S near-instant gear changes, which in the Horizon games translates to a very clean, snappy shift feel that many players prefer over a manual on a supercar.
- The 991 generation was the first 911 to use a fully digital instrument cluster as standard, a small detail that fans of the franchise notice when they look at the in-game cockpit.
