+@item Input support for a driving wheel, joystick, keyboard or mouse
+@item More than 30 car models
+@item 30 tracks
+@item 50 opponents to race against
+@item Lighting, smoke, skidmarks and glowing brake disks graphics
+@item Simple damage model and collisions
+@item Tire and wheel properties (springs, dampers, stiffness, etc.)
+@item Aerodynamics (ground effect, spoilers, etc.)
+@end itemize
+The difficulty level can be configured, impacting how much damage is caused by
+collisions and the level of traction the car has on the track, which makes the
+game fun for both novice and experts.")
