Radical SR3 RHD (Radical SR3)

The Radical SR3 RHD is a lightweight British track weapon built for pure driver engagement, combining motorcycle-derived power with a tubular spaceframe chassis and racecar aerodynamics. Purpose-built for circuit work, it’s one of the most iconic entry-level prototypes in the sim racing world.

Key Specs (BoP-dependent, typical sim values)

  • Powertrain: 1.5L 4-cylinder, naturally aspirated, mid-mounted, longitudinal SR3 race engine

  • Redline: ~10,500–11,000 rpm

  • Transmission: 6-speed sequential

  • Weight: ~570 kg

  • Dimensions: ~4,050 mm long × 1,770 mm wide × 1,080 mm tall | Wheelbase ~2,350 mm

  • Tires: Slick racing tires on lightweight motorsport wheels

  • Brakes: Ventilated disc brakes with race calipers

  • Layout: Mid-engine, rear-wheel drive

In the Simulator Feel

The SR3 RHD is a nimble, momentum-based lightweight racer that rewards commitment and precision. With so little mass to move, it changes direction almost instantly and feels alive over curbs, compressions, and fast transitions. It may not have huge horsepower, but the combination of low weight, aero grip, and short gearing makes it feel much faster than the numbers suggest.

Engine & Sound: The high-revving 4-cylinder engine has a hard-edged, mechanical note with a distinctive rasp as it climbs toward redline. It’s not about brute torque — the fun comes from keeping it in the power band and hearing the engine sing through the sequential shifts.

Handling Characteristics:

  • Cornering: Exceptionally sharp turn-in and excellent rotation. It’s easy to place, but it will punish abrupt steering or lifting mid-corner.

  • Traction: Strong mechanical grip for its class, though wheelspin can appear if you get greedy on exit or overdrive the rears on cold tires.

  • Braking: Very short stopping distances thanks to low mass, with great feel and easy trail-braking control.

  • Top Speed: Respectable on short straights, but it’s the cornering speed and acceleration out of bends that make the SR3 shine.

Driving Style Tip: Drive it smoothly and keep your momentum up. The Radical SR3 rewards late braking, tidy lines, and decisive throttle application — especially on technical circuits where lighter cars can carry speed through every section.

Livery & Aesthetics: The SR3 looks exactly like what it is: a tiny, aggressive prototype with exposed wheels, a low canopy, and a huge rear wing. The RHD cockpit gives it a more street-car-like driving position on the right side, but the overall vibe is pure race machinery.

Whether you’re chasing lap times or just want something brutally fun and responsive, the Radical SR3 RHD is one of the most rewarding lightweight cars you can drive in sim racing — simple, focused, and seriously quick.
