Based on real Formula 4 cars, this single-seat racing car. This makes it one of the most popular racing series in the world and is usually the second step on the road to Formula 1 after karting.
Equipped with a 180 hp Inline 4 engine and a dry weight of 580 kg, this bike is incredibly comfortable to drive even with the limited downforce it generates. This is the perfect car if you are looking for close racing and user-friendly controls for beginners.
Designed from the ground up to be as detailed as possible, it also features a fully accurate powertrain, detailed and animated mechanical parts, and fully adjustable aerodynamics.
Jbeam was also completely made from scratch with realism and close racing in mind. Everything has collisions, even the wheels and suspension. Say goodbye to the wheels sliding over the car and through each other.

Functions:
- Turbine limiter and on-the-fly braking force adjustment.
- 10 detailed skins, an unpainted version of raw carbon fiber and a monochrome version. UV scans of skins are included in the mod files for skinmakers.

In version 1.4 (12.11.26):
A small fix (hotfix) after the release of the BeamNG 0.40 update; new content has also been added.
List of changes:
- Added the driver's presence system (occupant system) from the BeamNG 0.40 version. If you are conducting competitions using the F4 mod, please note that this will significantly affect the lap time.
- A second page has been added to the dashboard screen (switched with the "U" key or the "R1+L3" button combination on the gamepad), which displays lap time and tire pressure.
- Updated trigger colors; the brake balance adjustment trigger is now represented as a mesh (three-dimensional model), rather than a sphere.
- Updated thumbnails; in the vehicle selection menu, configurations are now divided into subgroups.
