So what is "Solo" aka "Autocross"?
Solo, or more specifically, Solo II is a motorsport generally conducted on a large parking lot or airstrip, made of either asphalt or cement. Though some events are held at "real" race tracks around the country. "Pylons" (construction/traffic cones) are laid out to make up a course full of turns varying in degree, slaloms and many other elements. This course is then navigated by one car at a time and the driver with the quickest time wins. Cars are split into classes based on performance. Generally courses are different at each event, which adds a unique challenge having to memorize the course each time. For each pylon hit, the driver gets a penalty. This is generally 2 seconds added to your time. At the event prior to the start of the race, the course is open for walking. This is your chance to "learn" the course. Generally a novice walk is conducted by an experienced driver for people new to the sport. Event speeds are held to an average of 60mph. Though this may sound slow, especially compared to other motorsports, this can be deceiving because of the elements that the driver has to navigate through. At times, Solo requires more input from the driver then even Formula One racing, making for a fast and challenging experience at safe speeds.
