Solo® is the SCCA brand name for autocross competition. Solo events are driving skill contests that emphasize the driver’s ability and the car’s handling characteristics. This is accomplished by driving a course that is designated by traffic cones on a low hazard location, such as a parking lot or inactive airstrip. While speeds are no greater than those normally encountered in legal highway driving, the combination of concentration and car feedback creates an adrenaline pumping experience. It is like being in a movie chase scene, only you are holding onto the steering wheel instead of a box of popcorn!
Rally Cross is when one vehicle at a time is timed over a clearly defined course, with elapsed time and appropriate penalties (i.e. cones or off course) being the determining factor for awards. This shall not preclude the running of more than one vehicle at a time, provided they are separated on course by adequate time and distance to eliminate any possibility of a passing situation. Events are usually held on an unpaved, flat surfaces, where the course generally consists of short straight sections and connecting turns or corners. These courses generally emphasize vehicle handling and agility rather than speed or power.
