Bedales Greenpower team compete at Dunsfold

By Alex McNaughton, Head of Faculty: Art & Design

After competing in their first race at the Goodwood Motor Circuit in May, the Bedales Greenpower team took to the Top Gear test track at Dunsfold on 18 September for their second outing. Here, students Elliot Cundy and Lolo Gaio reflect on the experience, which has earned the team a wild card entry to the International Finals at Goodwood on Sunday 9 October. The team are now furiously tweaking and improving the car ready for the season finale and we are looking forward to another full and enjoyable day at Goodwood.

The Bedales Greenpower team attended their second race of the year at the iconic Top Gear test track at Dunsfold. Since the last race, the team had upgraded the car with a brand new cooling system and reworked steering. Due to a recent wave of illness as well as a clash of commitments, we only had two people available to drive – me and Lolo – between whom we divided three hours of racing time.

After our car had passed the all-important scrutineering, we were allowed out on the track for the first time to practice. Unfortunately, shortly into the session, another team’s car had rolled at the first corner, causing the deployment of an ambulance and halting the practice session for 20 minutes. Once all was clear, we started to learn the line of the track, putting down consistent, gradually improving lap times whilst learning the limits of our car. The first race was fast approaching, so after a swift battery change, we lined up on the grid for the first real test of our skill and car.

With 57 cars on the track, it was certainly a fight for space. I was driving the first stint, and was quickly learning that dealing with other people intruding onto my line would be a problem. Proceeding around the final corner, I was pushed into a cone by another car on my outside, forcing me to pit early to check for damage before letting Lolo hop in and take over. By the end of the first race, our battery was beginning to drain, leading us to place 23rd overall and achieving a top speed of 25mph.

Before the second race, my Dad realised that the nuts holding the wheel to the car were loose on both sides, which was causing the wheels to scrape against the car and make an unpleasant sound when turning. After fixing that, we changed the back wheels for the front wheels; the front wheels were larger than the back, which meant when swapped, the front wheels wouldn’t scrape against the car. Having a larger wheel on the motor also resulted in a longer gear ratio and therefore a slightly higher top speed of 26mph. 

We started the race in 24th place, and finished in 11th, having overtaken 13 cars in the first lap! Our car was running well, and it felt super fast. At the end of my first stint, we were in 8th position and after the pit stop, we were in 11th. Elliot had a longer, 40-minute stint to save on a pit stop against the rest, which got us up to fifth position!

Nothing eventful happened during the race until the lap that Elliot was due to come into the pits, when there was a red flag. Two cars crashed one corner behind him and the race stopped, with Elliot right behind the person holding the red flag. One car managed to get into the pits just before the red flag, so he got a free pit stop. As we were speaking to the race director Vaughan Clarke, he told us an impressive fact – there had only been one broken bone in all 22 years of racing. With the ambulance out, we were relieved to hear that neither driver was injured and the race could resume after 30 minutes. Elliot immediately drove into the pits, and then I was out… with a dying battery. The car was going much slower than when I started and we lost the lead we had gained.

In the end, we finished 17th (10th in our class), which was not too bad overall. The race was an incredible experience, and I’m so glad we did it. Next time, we’ll add wheel covers and make the car more aerodynamic, and hopefully we’ll be able to make it a full race without the battery dying on us. 

Bedales launches Greenpower team

By Alex McNaughton, Head of Product Design

Thanks to the generosity of the Bedales Parents’ Association (BPA), this year the Design department has brought the Greenpower Competition – a significant and highly competitive design and engineering competition for secondary schools – to Bedales.
 
The Greenpower Education Trust is a UK based charity which gets young people enthusiastic about science and engineering by challenging them to design, build and race an electric car. Established in 1999, Greenpower now work with 300 schools, with around 500 teams participating in the competition’s classes: Formula Goblin (for children aged 9-11); Formula 24 (for children aged 11-16); and Formula 24+ (for young people aged 16-25). 
 
As a number of Bedales students from Block 3 to 6.2 have a keen interest, aptitude and sympathy for design, technology and engineering, many of whom have previously expressed a desire to take part in the competition, we saw an opportunity to launch a Greenpower team – initially in the Formula 24 category – for a group of students to work throughout the year to build and improve a vehicle to race at nationally organised events, which are hosted at top race circuits such as Goodwood, Dunsfold, Castle Combe and Rockingham.
 
Our Greenpower team is open to anyone in school who wishes to participate – students and staff alike. As well as offering a practical outlet for students who have either not chosen or been able to choose to study Design, it gives students who are going on to study an engineering discipline at university a fantastic way to bolster their UCAS application and CV. The project also promotes cross-curricular collaboration, with the Physics department contributing time and expertise.


 
To get the team up and running, the BPA kindly funded cost of a complete kit to build a functioning vehicle, bodywork and battery charger for the vehicle, specialist tools and safety clothing for drivers and pit crew. This year we are learning many valuable lessons by rebuilding and improving a second hand kit car. Our long-term plan is to build a car from scratch to compete annually, continually improve our vehicles to make them more efficient and highly competitive. 
 
We currently have a team of 12 eager and motivated students from every year group who meet each week to build and develop our car for the 2022 season. The first race is in April which we are on course to compete in. 
 
The Greenpower Competition is fundamentally about producing an energy efficient electric car. It is ideally placed to promote and practically demonstrate the increasingly important and prominent issues of sustainability and the vital role of technology within this field.
