Radical SR3 LHD (Radical SR3)
The Radical SR3 LHD is a featherweight British track weapon from Radical's famous lineup of purpose-built sports prototypes. Built around a lightweight tube-frame chassis and powered by a high-revving inline-four, it delivers huge performance with very little mass — the kind of car that makes every input feel immediate.

In the Simulator Feel
The SR3 LHD is a nimble, highly responsive track car that rewards smoothness, commitment, and precision. With so little weight to manage, it changes direction instantly and builds speed with surprising urgency, even though the horsepower figure looks modest on paper. Its simplicity is part of the appeal: no wings-and-hybrid drama, just a brutally effective momentum car that teaches clean lines and confident inputs.
Engine & Sound: The naturally aspirated four-cylinder sings all the way to the top of the rev range with a metallic, hard-edged racing note. It doesn't have the brute-force roar of a big GT car, but it makes up for that with a crisp intake snarl and an eager, busy soundtrack that fits the car's lightweight personality.
Handling Characteristics:
Cornering: Extremely sharp turn-in with very quick rotation. It feels playful at the limit, but also forgiving enough for drivers who stay smooth.
Traction: Good mechanical grip for the class, though the low weight means throttle application still matters on corner exit.
Braking: Very strong braking performance thanks to the low mass, allowing later braking points than heavier rivals.
Top Speed: Not built for outright straight-line speed, but it carries pace well through technical sections and shorter circuits.
Driving Style Tip: Drive it like a momentum machine. Keep inputs clean, maintain corner speed, and focus on exit quality rather than overdriving the brakes or throttle. It shines on tight, technical tracks where agility matters more than power.
Livery & Aesthetics: The SR3 LHD has that classic Radical look: low, purposeful, and all business, with an exposed race-car shape that emphasizes function over flash. The left-hand-drive cockpit makes it especially approachable for sim racers used to road-car ergonomics, while still feeling every bit like a serious club racing machine.
Whether you're learning car control or chasing lap time, the Radical SR3 LHD is one of sim racing's purest lightweight performance cars — simple, fast, and extremely rewarding to drive.
