A great car to take part in an off-road trial.
The DW UltraBump is a powerful 2016 Ultra4 4400 class rock racer that will take you anywhere. Roads are not needed!

In version 5.0:
- Fixed: "Dead bull configuration is colored lighter than in older versions, is this on purpose? or I do not know, it just looks strange"
- Fixed a strange jump in downforce from the front, which caused her to twitch very much at speed.
- Some configurations have been reconfigured.
- Redesigned performance testing.
- The thumbnails of the images have been redone, yes, they are still too much enlarged, I don't care.
- Lockable differentials are now locked when appearing.
- Other minor fixes.
