The only thing that matters is the score. Passing between the pairs of poles the car must be driven with considerable awareness and judgement in order to maintain progress. Touching a pole, sliding backwards, reversing, or coming to a stop ends the run and the score will be the number on the pole ahead of the front axle line.
Spinning the wheels without forward movement is limited to 3 seconds at most events. Because the sections often have parts that are deep in mud, on wet grass, or on very loose surfaces, it is probable that in some cases only a few of the entrants will get right through to the end. Many will eventually find that at some point traction is irretrievably lost and that they must finish their turn on the section.
This in itself can sometimes be tricky, especially if stopped on a steep and slippery slope. For safety reasons passengers may be required to get out of the car and walk off the section while the driver brings the car out. If the car has to be reversed and the slope is very steep a technique for keeping control is to have the engine off and the car in reverse gear.
Usually there will be at least three runs on each section — often two in the morning and another after lunch. To make things interesting, after the first runs, the Clerk of the Course will have had a look at the scores for each section and if it is clear that most cars are getting through with relative ease some re-arrangement of the gates will be made. Conversely if it looks as if too many entrants are getting caught out in a particular spot the gates may be altered to make it slightly easier.
When the runs have been completed the scorecards are handed in and soon after the winners are announced. After that it is time to head for home, and for many that simply marks the start of looking forward to the next A7 Trial.
We are always looking for willing volunteers to help run the Austin Seven Trials on the day and will give instruction and guidance to those without experience. We particularly welcome those who would like to be marshals, help with the paperwork, or those who can assist the Clerk of Course in setting up and taking down the sections. Contact Mike Stone details below if you are able to lend a hand. The following is an example of part of the regulations from a Motor Club trial and details general requirements:.
Class 5 Related guest cars or demonstration cars - i. Well-based tyres with a tread pattern such that the blocks are not more than 10mm deep, nor more than 10mm apart laterally or circumferentially may run on a minimum of 5psi. Special grip, knobbly or hand-cut tread tyres must run at 15psi minimum pressure. Austin Seven productions cars. To meet the required design optimization, functional testing, engineering verification, and quality certification.
Accelerating your project from prototype to production. Trial runs before moving to manufacture, helping troubleshoot possible manchining issues in full production, and creates opportunities to save materials and production costs. The components used for show cars are typically a mix between prototype models, trial production parts, and production car versions. Interact with consumers at the tradeshows for the most direct assessment. As a professional manufacturer in CNC machining, we provide support for your upcoming pre-production schedule by CNC parts manufacturing high-quality, precision-machined.
Whether you need production-grade plastic, various metals, or custom aluminum machined parts, we have the ability to manage any machining project from prototype to low-volume for you.
This is a highly skilled team with professional knowledge and experience to help you reduce design risks and save production time and costs, and carry this through to full fabricating support.

Basically a route is layed out on a slope, usually grass, the aim is to get as far along the route as possible.
The route is marked with stakes that must not be touched by the vehicle. How far along the course you get determines your score, i. Therefore the lower scorer is the winner. Ballast can be added over the driving wheels but the silhouette of the car must not be changed in any way.
