Solo is the Sports Car Club of America (SCCA) brand name for autocross competition. Autocross events are low to medium speed auto events run on parking lots or other flat paved surfaces. The course is marked with traffic cones and designed to avoid the possibility of contact with obstacles. One driver at a time competes against the clock and time penalties are assigned for hitting cones. Drivers take several runs through the course and the driver with the best time wins.
You can compete in virtually any car although certain top-heavy vehicles like SUV's and mini-vans are not allowed. To equalize competition, cars are separated into classes based on the performance of the car and the modifications made to it. If you're driving a Honda Civic you'll be competing against Toyota Celicas, VW New Beetles and Nissan Sentras. Subaru WRX's are classed with Acura Type Rs, BMW 330s and Dodge SRT-4s. There are also separate classes for cars that have been modified with suspension or engine performance modifications.
Autocross emphasizes skill and precision rather than outright speed. The courses are tight and twisty. Speeds are low, most cars do not get out of second gear.
To enter all you need is a valid driver's license, your entry fee and a mechanically sound, safe car. Two drivers can share the same car.
If you've always wanted to race but thought it would be too expensive or require a dedicated race car, then autocross is for you. You can compete and have fun in the same car you drive to work every day. Autocross is a fun and inexpensive way to get involved in motorsports. You could be competing, not just spectating!
