TBO class cars include the XRT, FXO & RB4. They are turbo-aspirated sportcoupés with approximately 205bhp/ton. One is FWD, one RWD, and one AWD.

XR GT Turbo

XR GT Turbo
Short name XRT
Drive Front engined, rear wheel drive
Engine 2.0 litre turbocharged inline 4
Power 184 kW (247 bhp) @ 6035 rpm
Torque 345 Nm (255 lbft) @ 3896 rpm
Total-Mass 1223 kg (2696 lbs)
Power-weight 151 W/kg (205 bhp/ton)
Weight dist 51.0 F 49.0 R
Fuel tank capacity 75 ltr
Suspension Front: MacPherson Strut
Rear: MacPherson Strut

Information

Take the XR GT, enlarge the engine to a nice round 2 litres, chuck a turbocharger under the bonnet for good measure and give it some meaner bodywork, and the XR GT Turbo is born. Although infamous for it's turbo lag, it does actually drive very nicely once you have become used to its handling and rather unique power delivery. Old timers still call it the GTT.

Setup tip

Just a touch of understeer is all that's need to control this car, once you've learnt to anticipate the turbo lag it's really just a more powerful XR GT.

RB4 GT

RB4 GT
Short name RB4
Drive Front engined, all wheel drive
Engine 2.0 litre turbocharged inline 4
Power 181 kW (243 bhp) @ 6035 rpm
Torque 340 Nm (251 lbft) @ 3896 rpm
Total-Mass 1210 kg (2667 lbs)
Power-weight 150 W/kg (204 bhp/ton)
Weight dist 56.0 F 44.0 R
Fuel tank capacity 75 ltr
Suspension Front: MacPherson Strut
Rear: MacPherson Strut

Information

The only road car to sport an AWD drivetrain, this makes it the ideal car for all the rallycross courses. The RB4 is also fun to drive on the road tracks, but is slightly slower than the GT Turbo and FXO due to the mechanical loss inherited from the AWD layout. It is the easiest to drive out of the trio, however.

Setup tip

Understeer is your enemy here. Only add as much as you feel you need into the suspension and push the torque split back until you can push the rear out slightly with the throttle. This will also help even out tyre heating & wear.

FXO Turbo

FXO Turbo
Short name FXO
Drive Front engined, front wheel drive
Engine 1.9 litre turbocharged flat 4
Power 175 kW (234 bhp) @ 6357 rpm
Torque 305 Nm (224 lbft) @ 4336 rpm
Total-Mass 1136 kg (2504 lbs)
Power-weight 154 W/kg (210 bhp/ton)
Weight dist 57.0 F 43.0 R
Fuel tank capacity 75 ltr
Suspension Front: MacPherson Strut
Rear: Trailing Arm

Information

The favorite car in S1 (initially), it is very accessible and fun, being a fast front wheel driven car. It's meaty tyres and light weight ensures it corners well. The XRT catches back up on long straights though.
