Audi R8 LMS ultra (GT3)
The Audi R8 LMS ultra is Audi’s upgraded GT3 evolution of the mid-engine R8 platform, built to FIA GT3 regulations and used across sprint and endurance racing worldwide. It sharpens the original R8 LMS with improved aero, revised cooling, reduced weight, and a more refined race setup while keeping the naturally aspirated V10 character that made it such a popular customer car.

In the Simulator Feel
The R8 LMS ultra is a stable, approachable GT3 car that rewards smooth driving and confidence under braking. It feels planted at speed, with predictable weight transfer and a chassis that gives the driver plenty of feedback before the limit. Compared with newer GT3 machinery, it has a more mechanical, old-school personality — still fast, but with a bit less of the electronic polish and aero grip found in later cars.
Engine & Sound: The naturally aspirated V10 is the star of the show, producing a hard-edged, high-revving scream that is instantly recognizable. Throttle response is crisp, and the engine pulls cleanly toward the top of the rev range with a racing soundtrack that feels urgent and visceral. It lacks turbo torque, so momentum and revs matter, but that also makes the car especially satisfying when you get it right.
Handling Characteristics:
Cornering: Neutral and confidence-inspiring, with mild understeer if you enter too hot.
Traction: Good rear grip, though aggressive throttle can still unstick the rear on corner exit.
Braking: Strong and predictable, with excellent stability for trail braking.
Top Speed: Competitive in its era, though usually not the fastest GT3 on the straight without favorable BoP.
Driving Style Tip: Keep the car in a smooth rhythm. It rewards clean braking, early rotation, and disciplined throttle application more than big, aggressive inputs. It shines on technical circuits where mechanical grip and balance matter as much as outright aero.
Livery & Aesthetics: The R8 LMS ultra has the classic Audi GT look — low, wide, and muscular, with sharp body lines and a purposeful front end. The proportions of the R8 road car translate beautifully into a race car, and the large rear wing, vents, and diffuser give it a proper endurance-racer presence.
Whether you're running sprint races or longer stints, the Audi R8 LMS ultra remains one of the most enjoyable and iconic GT3 cars in sim racing — a high-revving V10 machine with balance, character, and unmistakable Audi style.
