Shell Eco-Marathon, the world's slowest and most fuel-efficient 'race', is more fun than it sounds

Come join the party, as students drive at 20mph in a bid to beat the current record of 9,000 miles per gallon

Part of Shell's Make the Future Live festival in London's Olympic Park, Stratford, the Eco-Marathon sees 170 university teams battle to be the stingiest driver IN THE WORLD.

Technically this means seeing how far they can go on one litre of petrol (or its energy equivalent, in the case of electric, LPG and hydrogen cars). 

However, as that could take rather a long time – the current record holder for this event did the equivalent of 2,380 miles ('the distance between Paris and Moscow', it says here), and they never get much above 20mph – what they actually do is 10 laps of a one-mile course, using as tiny an amount of fuel as possible.

Cars come in two classes: Completely Terrifying and Less Worrying But Amazingly Loud. 

The Terrifying ones are built entirely for aerodynamic efficiency and so are about an inch off the ground, with looks that vary from "Knocked up in a garage by a drunk" to "highly polished, but there's still no way I'm getting in it"

The "Urban" class look pretty much like Smart cars. The one I tried employed a one-wheel drive system, running off of a scooter transmission, with a fuel tank about the size of a quarter bottle of Scotch. 

As a result, it was the loudest thing I have ever been in, apart from the Batmobile. (opens in new tab)

I wasn't sure the sheer loudness would come over in the video we shot. But as you can hear, it really did.

Shell is also showing off an autonomous eco-car, built by Oxford Robotics Institute. I got to have a go in that too, and I've got to say, sitting as a car drives its damn self around a track, up hills and over speed bumps just never gets old. The sooner all cars are like this, the better..

To that end, next year will see a self-driving category added to the Eco-Marathon, so be sure to come down and see that – but maybe don't go too near the track.

Make the Future Live kicks off on Friday night with Lates, 'a special after-hours event for over 18s'.

Among other things, this features a slightly bizarre dream team of The IT Crowd’s Richard Ayoade, Gadget Show’s Jason Bradbury and the Intelligence Squared Podcast crew. They and a further panel of experts will be 'debating how London could become the world’s first carbon neutral city by 2050.'

Over the course of the Bank Holiday weekend you can then watch 170 teams compete in the Eco-Marathon, check out all manner of energy-saving stuff, eat food, drink booze, see celebs, enjoy 'weird science' demos, and listen to the musical stylings of popular songstress Alesha Dixon. Mmm-mm.

Further information? Yes indeed. (opens in new tab)

Duncan has been writing about tech for almost 15 years, during which time he has attended every event going, apart from Apple ones, as he mysteriously doesn't get invited to them. He has covered everything from smartphones to headphones, TV to AC and air fryers to the movies of James Bond and obscure anime. 

Duncan's current brief is everything to do with the home and kitchen, which is good because he is an excellent cook, if he says so himself. He also covers cycling and ebikes – like over-using italics, this is another passion of his. Duncan also edits T3's golf section because fuck it, someone has to. Dave Usher does all the real work on that bit, though. In his long and varied lifestyle-tech career he is one of the few people to have been a fitness editor despite being unfit and a cars editor for not one but two websites, despite being unable to drive. He also has about 400 vacuum cleaners, and is possibly the UK's leading expert on cordless vacuum cleaners, despite being decidedly messy. A cricket fan for over 30 years, he also recently become T3's cricket editor, writing about how to stream obscure T20 tournaments, and turning out some typically no-nonsense opinions on the world's top teams and players.

Before T3, Duncan was a music and film reviewer, worked for a magazine about gambling that employed a surprisingly large number of convicted criminals, and then a magazine called Bizarre that was essentially like a cross between Reddit and DeviantArt, before the invention of the internet. There was also a lengthy period where he essentially wrote all of T3 magazine every month for about 3 years. 

A broadcaster, raconteur and public speaker, Duncan used to be on telly loads, but an unfortunate incident put a stop to that, so he now largely contents himself with telling people, "I used to be on the TV, you know."
