The Machines
Two programs. Two very different ways to go fast.
Radical
Radical: Sports Prototypes
Radical cars are lightweight sports prototypes built purely for the track. Think low, light and grippy, with aerodynamic downforce, racing slicks and a driver-focused cockpit. They are known for being quick, rewarding and relatively accessible, which makes them a great platform for racing hard and learning fast.
What to expect:
- Prototype design: built for racing, not for the road
- Light weight and aero grip for big cornering speed
- Close, competitive racing
- A proper driver's car

GT4
GT4: Production-Based GT Racing
GT4 is a class of race cars developed from road-going sports cars. They keep the recognisable shape of the original but add race safety equipment, race suspension, brakes and tyres, and aero. Classes like this usually use performance balancing to keep different makes competitive, so it is as much about race craft and team work as outright speed.
What to expect:
- Cars based on production sports cars
- Longer races with pit stops and driver changes are common
- Competitive grids with many manufacturers
- Great for fans: you can spot the road car in the race car
