Never before though has there been such pressure for our favourite method of transportation to become less polluting and less energy consuming. The effects can already be seen in many race series where economical diesel race cars have been competing and indeed winning for years now, and where many motorsports are aiming to cut costs and cut their carbon emissions as they travel around the globe. Even in the high octane world of motor racing, every little helps.
But what if we look further into the future? One man, Moritz Martin, has done just that with his concept for the futuristic 1 Liter Racing League. The concept is Mr Martin's degree project and is apparently inspired by "the insanity of Swamp Buggy, Land Speed Record races and the Eco Marathon". The idea is to use tactics and skill to finish the race on just a single litre of fuel. The driver's cause is aided by being able to skim the car across thin layers of water and other varied surfaces to use as little energy in movement as possible. The car can be aided in sliding by rear-wheel mounted air nozzles for "frictionless steering".

Your options are clearly a little limited - after all, motor racing is hardly the most eco-friendly sport in the world. That isn't to say though that it isn't possible - if you look hard enough.
Kei Car Racing
(Image: Speedhunters.com)If you live in Japan, you've probably come across this already. Kei-Jidosha are Japan's answer to overcrowding on the roads, and thanks to their minimal proportions and even more miniscule engines (660cc and 63bhp is the current maximum limit), they're the perfect choice for low-consumption racing. There are series for Keis both old and newer, and of course you could always take one to an autocross event like this Daihatsu Copen on YouTube, where small proportions and low inertia do wonders for cornering ability.
Eco Marathons
(Image: Thinkorthwim.com)Events like the Shell Eco Marathon are growing in popularity all the time and the records for miserly fuel consumption tumble quicker than the times at a 100m race with Usain Bolt. The current World Record is a mind-boggling average of 10,705mpg, achieved by team Microjoule in 2003. Of course - these aren't really "cars" so much as tiny engines in composite cigars with a driver filling the rest of the available space - but it's still a race of sorts and like the 1 Liter Racing League aims to use as little fuel as possible over a set distance. And you can certainly do the race on a small budget too, even if the top teams spend a little more to achieve the figures they do. You could turn up with a lawnmower-powered soapbox racer if you wanted.
Citroën 2CV racing
(Image: Maria Cooke @ 2cvracing.co.uk)Perhaps a bit of a wild card, but even so, people do race the tree-hugger's wheels of choice and there are thriving race series for the little cars all over Europe - the UK Classic 2CV Racing Club has been around for over 20 years! The cars are cheap to buy, prepare and run, and with the weight of a feather in a helium updraught even the modest power from a tiny 600cc engine is able to provide plenty of fun without using a lot of fuel in the process. It's probably one of the cheapest and most economical circuit racing series in the World.
Okay - so none of the above are quite as high-tech as Mr Martin's concept, but they prove that even today you can take part in motor racing that doesn't break the bank, and doesn't pray too heavily on your environmental conscience...
Of more current interest is the discovery that, contrary to popular belief, some people are attaining stratospherically high mileages from petrol-electric Hybrids like the Prius. One owner managed to get 349,531 miles out of his first-gen Prius before it was unfortunately written off. The mileage isn't the most surprising aspect though - this is reserved for finding out that the mileage was achieved
