Autograss racing is a strictly non-contact sport, where specially prepared saloon cars and purpose built specials (see the cars section) race around a laid out oval on a natural surface (initially grass,but more often dirt or even mud). Since both men and ladies may race any of the ten classes, and juniors (aged 12 to 16) may race class one, autograss is a truly family sport, where the whole family can share a car.

Autograss is the affordable motorsport. At club level there is no need to spend huge amounts of money to be competitive, although a top level modified car can cost upwards of £10,000, many cars can change hands for less than £300 (sometimes complete with trailer).Club membership and racing licence is ~£30-£40, entrance fees are generally ~£3.50,signing on is usually ~£1.00. Apart from travelling to meetings, wear and tear on the race car and a couple of gallons (at the most) of fuel, that is it. A local meeting need cost no more than £20, barring mishaps, including travelling.

There are nearly 60 NASA (National Autograss Sport Association) affiliated clubs,organised into 21 leagues, spread thoughout England, Wales and Ireland, with over 5000 members. So, several race meetings can be found, somewhere in the country, nearly every weekend between March and October. There are a lot of big 'open' meetings thoughout the racing season as well as several race series, the biggest and most prominent of which is the BAS (British Autograss Series).

The Mens National Autograss Championships, held in August, are for the top 400 drivers who have had to qualify through their leagues. The Ladies and Juniors National Championships are held in September, with entry by application.
