FXR, XRR & FZR: These racecars are similar to the Japanese Super GT (formerly JGTC) GT500 class. They have approx. 450bhp/ton.

FXO GTR

Short: FXR

Front engined, all wheel drive
Moteur: 2.0 litre turbocharged flat 4

Puissance: 365 kW (490 ch) @ 6278 tours/min
Couple: 627 Nm (462 lbft) @ 4782 tours/min
Poids: 1120 kg (2470 lbs)
Rapport poids/puissance: 323 W/kg (445 bhp/ton)
Distribution du poids: 57.5 F 42.5 R
Capacité du réservoir: 100 ltr

The FXO GTR is the easiest of the GTR cars to drive, thanks to its stable handling and four-wheel drive. Unfortunately it's also the slowest over a single lap. In the hands of a skilled driver it can usually beat most comers, but even the best FXO GTR driver can't catch a well-driven FZ50 GTR or XR GTR in a sprint race. In endurance races the playing field is leveled somewhat, as the FXO GTR is easier on its tires than the other two GTR cars and has superior fuel economy. Ultimately the FXO GTR is a great car for somebody just getting used to the extra power offered by the GTR cars or for somebody who just wants to have some fun in the GTR class, but if you want wins and don't like long races you have to move to one of the rear-wheel drive GTR cars.

Conseils: Need a little oversteer for this car, and send plenty of the torque rearward to keep tyre temperatures equal front and rear. Best keep the differential locking fairly light on the coast side to help turn in, which is this cars main strength.

XR GTR

Short: XRR

Front engined, rear wheel drive
Moteur: 2.0 litre turbocharged inline 4

Puissance: 365 kW (490 ch) @ 6278 tours/min
Couple: 627 Nm (462 lbft) @ 4782 tours/min
Poids: 1100 kg (2424 lbs)
Rapport poids/puissance: 332 W/kg (453 bhp/ton)
Distribution du poids: 55.4 F 44.6 R
Capacité du réservoir: 100 ltr

Is the XR GT Turbo not man enough for you? Slicks, wings, silly power and an angry face, this car has had the works done to it. Nobody knows what the LFS tuning division did to the turbocharger to get double the power out of the engine, but it works, and we are forever thankful. It likes to eat FXO GTRs for breakfast, so watch out.

Conseils: Not much understeer needed for these cars, again just use downforce for high speed stability. Need to keep the differential fairly tight so you can put down all that power. Highish tyre pressures at the rear, less at the front.

FZ50 GTR

Short: FZR

Rear engined, rear wheel drive
Moteur: 3.6 litre flat 6

Puissance: 365 kW (490 ch) @ 8106 tours/min
Couple: 503 Nm (371 lbft) @ 5267 tours/min
Poids: 1100 kg (2425 lbs)
Rapport poids/puissance: 332 W/kg (452 bhp/ton)
Distribution du poids: 35.3 F 64.7 R
Capacité du réservoir: 100 ltr

This is what happens when a not-so-sane person looks at the FZ50 and says "Mmm, nice, but could do with a bit more power." 130bhp more to be exact. Like the XR GTR, it was given slicks, downforce, gorgeous looks and lightened, but just ended up better. Not for the faint hearted, since it will do it's best to rip it out the first time you drive it.

Conseils: See tip for the XR GTR.
