RB4 GT on LFS.net

RB4 GT is an all-wheel drive, front engined road car.

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.


The RB4 was first teased on May 10, 2023, in a news piece about the S1 release plan (a screenshot of the RB4 in South City). The community first got their hands on the car in test patch 0.2E1, on June 1, 2003. It was released on July 17, 2003 as a part of the initial S1 release (0.3A). A revamped version of the RB4 was released in the 0.7A patch on Dec 16, 2021, along with vehicle mods.

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.
