Radical SR3 XXR (Radical SR3)

The Radical SR3 XXR is a lightweight, purpose-built sports prototype from Radical Motorsport, designed to deliver huge performance through low mass, slick aerodynamics, and a high-revving naturally aspirated engine. It’s one of the most accessible ways to experience true prototype-style speed without stepping into a full LMP machine.

Key Specs (BoP-dependent, typical sim values)

  • Powertrain: 1.5L 4-cylinder naturally aspirated engine, mid-mounted, longitudinal

  • Total Output: ~232 hp (173 kW)

  • Redline: ~10,800 rpm

  • Transmission: 6-speed sequential paddle-shift

  • Weight: ~620 kg

  • Dimensions: ~4,120 mm long × 1,850 mm wide × 1,090 mm tall | Wheelbase ~2,540 mm

  • Brakes: Ventilated racing discs with multi-piston calipers

  • Layout: Mid-engine, rear-wheel drive

In the Simulator Feel

The Radical SR3 XXR is an extremely agile, momentum-based race car that feels more like a tiny prototype than a traditional sports car. With so little weight to carry, it changes direction instantly, builds speed aggressively, and rewards commitment through corners. It’s not about raw horsepower — it’s about keeping momentum, maintaining aero load, and using every inch of track.

Engine & Sound: The little high-revving engine is eager, mechanical, and frantic, with a sharp intake note and a buzzing top-end that makes the car feel alive at every rpm. It doesn’t have the thunder of a GT car, but it has a pure race-car urgency that makes every upshift satisfying.

Handling Characteristics:

  • Cornering: Exceptionally quick turn-in and strong mid-corner grip. It thrives in flowing sections and rewards confidence.

  • Traction: Good mechanical grip for its size, but sudden throttle inputs can still upset the rear due to the light chassis.

  • Braking: Very short stopping distances and excellent brake feel thanks to the car’s low mass.

  • Top Speed: Modest compared to GT and prototype machinery, but it accelerates briskly thanks to the low weight.

Driving Style Tip: Drive it smoothly and decisively. The SR3 XXR shines when you commit early to inputs and keep the car balanced; overdriving it or sawing at the wheel usually costs more time than it gains. Tight, technical tracks and club-style circuits are where it really comes alive.

Livery & Aesthetics: The SR3 XXR has the classic Radical look: low, sharp, uncluttered, and unapologetically race-focused. Its compact cockpit, exposed prototype styling, and aggressive aero make it look fast even standing still, while the livery choices usually emphasize the car’s clean bodywork and motorsport credibility.

Whether you're chasing hot laps or racing door-to-door, the Radical SR3 XXR delivers a raw, lightweight, and deeply engaging sim driving experience that sits perfectly between club racing and full-on prototype speed.
