WHAT IS AUTOGRASS?
JUST A BRIEF OUTLINE OF MOTORSPORTS BEST KEPT SECRET.
There are 11 NASA Classes, differing by type of set up and engine sizes, from near standard 1000cc Minis through to specifically designed spaceframed single seaters with monster V8 or twin motorbike power!
Up to eight cars start on a straight line grid and race over 4 - 10 laps. This results in the major race meetings, most of which are staged over the course of two days, offering upwards of 200 races! All Classes normally race through qualifying heats and finals followed by, time and weather permitting, open races where all Classes have the opportunity to race each other.
The social aspect of the sport is a very large factor in what makes the atmosphere so enticing and allows friends from all over the United Kingdom to meet and catch up at the 'larger' events. The family nature is still, as has always been, an important factor - sometimes all members of the same family are seen to be sharing on car and racing at one meeting. Although having said this, Juniors (10 - 16 years) are restricted to two less powerful Classes for obvious reasons.
Only a small number of Autograss events require competitors to enter prior to the day of racing. With the exception of the National Autograss Championships, which requires qualification / registration, a NASA Licence holder can race at any NASA meeting just by turning up with a car that meets the National Construction Rules for it's Class.
Please Note: Some meetings throughout the Autograss calendar are restricted. If you are unsure, it is strongly advised that you contact the host Club / League to check whether restrictions are in place before travelling.
Racing Licences are available through a Club of your choice for Mens; Ladies and Juniors. Also available are Mechanics and Social Licences for those who do not wish to race but would still like to be a part of this very affordable motorsport. It is first and foremost an amateur motorsport, so there are always plenty of opportunities to join in and help to run your Club. As time goes by, there are also chances to become more involved with the sport on a high organisational level, or of course you can simply turn up and continue enjoying the racing!
If you would like to know more specific details, the best place to start is by visiting your local race meeting and witnessing the action first hand. To find your closest Club, please see the Venues page of this website. Once you know which Club you want to visit, you can then find out when they are next racing by visiting the Fixtures page. When you attend an Autograss event, you can speak with people who will always be more than happy to give you more information about the sport. Alternatively, on the Contact page, you can find contact details for the sports Board of Directors and Officials who are always happy to answer any questions you may have.
about the classes
This is one of the ideal classes for beginners to the sport; those who want close racing or are racing to a low budget. This is the only saloon class with which 10 - 16 year olds are able to race the same vehicle in their own category. It's also a class that people with previous racing experience are keen to join.
A complete family often participate in this class with the same car - Dad racing the mens category, mum in the ladies and their son/daughter racing in the junior category.
There are no special tuning/modifications allowed in this class. The engine/gearbox must remain basically standard within strictly enforced minimum and maximum tolerances. This helps to ensure that costs are kept within affordable limits and that there is close racing both at Club and National level.
To ensure that the field is kept as possible, there are a limited amount of vehicles that can be used. At the moment, this includes the classic Mini saloon; Citroen AX; Toyota Yaris or Nissan Micra. The engine and gearbox must be from the same car and using an engine no more than 1000cc capacity.
This class is another great one for beginners to the sport and for those starting their Autograss career; those racing on a low budget and those who wish to race either front or rear wheel drive vehicles, although the front wheel drive cars have become far more dominant over the years.
