The Gymkhana Brake Test

Right, so we’ve done all the introducty/explainy bits, lets get down to the results.

Just as a reminder, there were two criteria we were testing.. how well would our £2,500 sports cars do, some nearly 20 years old, against a brand new £25,000 sport car AND how well would we do against the Highway Code, from 60mph:

Well, the results may surprise you.

First of all there wasn’t much in it. With the exception of the Mercedes SLK. But then, as Neil pointed out, he should probably have taken all the camera equipment out of the boot.

All of our cars easily beat the 55 metres the Highway Code considers typical, so you’ve got to wonder what rust buckets they used to measure that.

What was surprising was that the GT86 didn’t win. Now, this test was in no way scientific, so we can’t say with absolute certainty that if we did it 100 times over this would be the result every time. But on the day, this is what happened. It got beat by 4 other cars.

The winning cars were in fact the oldest and newest in the Le Mons fleet. They are also, both, the only cars wearing very sticky -track day- rubber. Now, what does that tell you. Oh, and the FTO? No ABS, unlike all the other cars here.

 

Next time – the Slalom.

Challenge 11 – The Gymkhana

…and we’re back.

You may have noticed we’ve been a bit lax when it’s come to updates lately. That’s entirely due to the fact that in June we hosted the amazing Roundel Run, a 75 car & bike strong adventure through the counties of Surrey, Sussex and Kent, all in aid of the Biggin Hill Festival of Flight and our charities. More on that on the Roundel Run website, Facebook and Twitter feed.

Although the Roundel Run was a great success, raised a nice amount of money for charity and will be held again next year (hint hint) it did mean most of the team were flat out, so catching up on sleep and work were required.

That said, on to our gymkhana!

 

What’s a gymkhana?

Well, basically, and according to Wikipedia, it’s roughly:

“a place where skill-based contests were held”

From an automotive point of view you might know it best for a gentleman named Ken Block, who does things like this:

Obviously that’s slightly more adventurous (and skillful) than we might manage in our £2,500 cars, but we thought we’d take the name anyway and test our cars to their maximum too. Just slightly less insanely.

 

Where can you properly play with your cars?

Obviously, unlike Mr Block, we couldn’t have closed any roads, and with our limited budgets we couldn’t exactly rent a whole track or airfield. But, a couple of quick calls to our friends at Car Limits later and we had a small section of the North Weald airfield for our very own! A massive thanks to Andrew and his team for making that happen!

What’s this about a special guest?

Ah, you’ve seen our tweets!

 


One of the things we’ve been trying to achieve is to see if a £2,500 sports car is as much fun as a super car. For this event we thought we’d ratchet that down a notch and see how our cars compared to a modern day sports car.. and what better opposition than-the-already-future-classic Toyota GT86.

And thanks to the great folks at Hills Toyota of Bishop’s Stortford, we we’re able to borrow one, plus a driver, for the day. Adam was so excited about taking part he arrived before anyone else, in a gorgeous black ’15 plate ’86 auto, with the Aero pack. An absolutely stunning car. And fantastic to drive too.

We chose the ’86 as it matched many of our cars – RWD, reasonable power (200 bhp), coupe styling and, like 5 out of the 9 Lemons – Japanese. A few of us left that day, more impressed with it than we already were. It would be fair to say it’s on a few must-have lists now.

A massive thanks to everyone at Hills, they couldn’t have been more welcome, accommodating or sporting! In fact, they even joined us on the Roundel Run!

On the down side though, two of our drivers couldn’t make it on the day. Steff and his S2000 and Duncan and his MX5 were all sorely missed, as we believe they would have done very well in our activities. Still, more points for the rest of us!

 

 

So, what were the activities?

The idea behind the day was based on further testing our cars. We’d had them on the dyno, we’ve tested their acceleration, some of the cars have been put through their paces on track, but we’d never really tested braking and handling in a comparable way.

With limited space (just one long straight) and technical resources (i.e. no official timing gear, just stopwatches), we needed to keep things as simple as possible.

Braking

The braking test was based on the publish Highway Code for Typical Stopping Distances. We wanted to see how our cars might do against each other, the GT86 and the official numbers.

Highway Code Stopping Distances

Each car was driven up to 60 mph and then stopped as quickly as physically possible. We ignored the Thinking Distance element by setting out two cones through which the cars would pass, and at which point they were to start braking. Our target to beat – 55 metres.

Handling

What better way to test a car’s handling than putting it on a skidpad and seeing what G numbers it’ll achieve? Well yes, except we didn’t have a skidpad or something scientific to measure G forces with. So we settled on the next best thing – a cone course. A quick slalom down, followed by a big turn, slalom back and then a quick sprint to the finish. Our GT86 set the benchmark, and we all followed!

 

The results!

They were, surprising. But you’ll have to wait for the next post to find out!
