The future of motor racing?... Or are we already there?

Since man invented the motor car, his primal instinct for excitement and speed has always compelled him to race it against the next man's motor car.

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".

It's a facinating concept, and one that looks a lot of fun. However... what if you want to take part in some eco-friendly racing here, and now? 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

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

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.

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...

My thanks to Mr Martin himself for his permission to use the 1 liter pictures. Tarmac wishes him the best of luck in his degree!

Guerilla marketing for Alfa MiTo; New Multiair MiTo

Take a walk through Jesmond in Newcastle-upon-Tyne at the moment and your eyes might be drawn towards the pavement. Normally, it's nothing particularly special, but recently some rather unorthodox adverts for Alfa's MINI rival, the MiTo, have appeared on some of the paving slabs.

With Alfa's baby being aimed at the younger and more fashion-conscious types, these adverts in the affluent and student-heavy area of Jesmond are a great example of guerilla marketing. The images are created using a technique that involves cleaning an sandblasting the ground through a template. There are apparently 1300 similar adverts across the UK.
The pavement adverts also coincide with a first look, via What Car?, at the new MiTo Multiair, an ultra-clean and efficient MiTo using advanced 1.4 petrol engines. Instead of a conventional camshaft, the MultiAir engine uses a series of oil-fed solenoids which can precisely meter out fuel in any given situation. As well as improving economy by 10% and reducing NOx emissions by 60%, the system apparently improves throttle response and increases power and torque, especially at lower revs.

80mpg from diesel-powered first-gen Insight

Yes, you read that correctly. AutoBlogGreen has released news that a company called Red Light Racing has installed Volkswagen's 1.2 litre, 3-cylinder Pumpe Düse TDI in a first-generation Honda Insight and the net result is 80mpg in US gallons - a staggering 96mpg imperial.

The engine has been taken from Volkswagen's Lupo 3L, a model that was only available in mainland Europe and itself made 94mpg imperial, equivalent to 3 litres/100km. The Lupo however was solely diesel-powered - and Red Light Racing state that they haven't even hooked up the Insight's hybrid motor to the diesel unit yet and once they do there could be another 15-20% improvement.

The Lupo 3L was highly modified from the standard Lupo TDI - like the Insight, it used aluminium in much of its construction, and also in common with the Insight it used low rolling-resistance tyres and a stop-start function to save fuel when stopped in traffic. The engine produces 61bhp and makes 140Nm of torque, which is 9bhp less than the Insight's 1.0 litre petrol IMA unit but a useful 27Nm more torque. Coincidentally, both Lupo 3L and Insight weigh in the region of 850kg, so the engine seems ideal for use in the Insight, though according to Red Light Racing the installation naturally wasn't too straightforward.

Diesel clatter aside, the new engine should provide very pleasant driving characteristics too. The final quote goes to Red Light Racing, clearly a company after Tarmac's heart: "The main idea was to take existing hardware, hack it, and make a vehicle that could be produced by major manufacturers or individuals that would deliver tremendous fuel economy without a tremendous leap in technology. I believe we succeeded."

More T25 news - Gordon Murray's microcar driven

The new issue of Autocar magazine, and for that matter their website, brings us more information of Gordon Murray's fascinating T25 project, a city car designed to have a construction to destruction carbon footprint 40% smaller than that of the average city car.

The biggest bit of news is that the car will seat three and not two as previously suspected, in a McLaren F1-style centrally-seated driver, flanked by two passengers - despite the car being significantly smaller than even a Smart ForTwo.

More interesting is that Autocar have managed to drive a body-less prototype powered by a 660cc three-cylinder engine with a Smart-style semi-auto gearbox. The full test can only be read in Autocar's magazine, but Autocar columnist and feature writer Steve Cropley seemed mighty impressed by the mule's capabilities - including flat cornering, great steering, a good ride and fantastic feel to the controls. Not only this, but the car can apparently turn in only six metres.

Of course, the mule isn't exactly much to behold, but that it can impress in such a basic state is very important - the driving characteristics of the Smart and rival Toyota iQ haven't exactly come in for much praise, and nor have their prices. To this end, Murray is still touting £6,000 as an entry-level figure.

In other T25-related news, another teaser-shot of the car has been released, showing what the front of the car is shaping up to look like. It's probably not going to be much of a looker, but there's still a lot to come from the T25 project so we're holding our breath.

Smart Roadster to return?

This is the news Tarmac has been waiting for - Autocar has released details that Mercedes-Benz has applied for several patents for a new three-seater Smart, touted to be known as the ForThree, in keeping with the names of other Smart models.

As you can see from the images, the new car will have a seating layout similar to that of the McLaren F1 supercar, with the driver sitting centrally and passengers behind and to either side of the cockpit.

According to the drawings and Autocar, the central seat is designed to swivel and slide towards the door to ease access. The car could potentially use both petrol and diesel units that Smart currently produce, and it may even be available with an EV option by the proposed 2014 release date. Mercedes are also developing a dual-clutch seven-speed transmission for use in the next A-Class, and this may even find it's way into future Smarts such as the ForThree.

The first generation roadster was nowhere near as popular as it was expected to be, selling just over 43,000 units in its two year production run. If Mercedes and Smart can find the right price for the ForThree, they may well overcome the main hurdle the first model faced - it's expense compared to more powerful and practical rivals.

Tarmac will be keeping a keen eye on the progress of this story and will bring you further developments as they happen.

Letter to Auto Express

I don't often feel compelled to write in to motoring magazines. Actually, I tell a lie. I often feel compelled, but rarely follow through with the desire.

However, Auto Express columnist Mike Rutherford (who also writes for The Times and The Telegraph) has finally irritated me enough to put digit to keyboard in his column for the 17-23 June issue of Auto Express. I shan't replicate his column in full - Mr Rutherdford aside the magazine is still one of the better motoring titles out there and this issue has an interesting comparison test between old and new Mazda MX-5s. But I digress.

Mr Rutherford writes: "If we're to believe those in authority and their ecomental pals, global warming is the greatest threat to mankind. The allegation is that the phenomenon will kill untold millions of people and places. What's more, some mentalist 'experts' deviously give the impression that CO2 emissions from 'murderous' motor cars are largely or entirely to blame for scorching the earth and allowing the planet and its inhabitants to crash and burn.

"I hear what they're saying, and I acknowledge their right to express their own opinions and predictions. But can we have less of the crystal ball gazing and scaremongering, and more of the hard facts, please? Where is the unbiased, incontrovertible, compelling evidence which proves beyond doubt that global warming will, on its own, destroy earth and mankind?"

He goes on to say: "When was the last time you actually heard any of the leading political parties even mention the T word [transport], let alone say what, if elected, they intend to do with the roads, rails, waterways and sky routes?"

The rest of his column devolved into a rather dull bash at politicians who've done far worse things than to not mention transport policy in their manifestos. Anyway, after adding weeks, months and years worth of straw with Mr Rutherford's smug columns, the camel's back finally succummed:

"Perhaps if Mike Rutherford is to get the unbiased evidence of man-made global warming he desires, he should first avoid biasing his column too far in the other direction. Labelling those who consider motor vehicles to be a large component of global warming "mentalists" is ignorant and arrogant. Regardless of whether Mr Rutherford likes their findings or not, these are still the findings of scientists which still hold more weight than the smug rantings of a mouthy motoring journalist. Indeed, Mr Rutherford is not even being forced to believe these findings and there are many, many other theories out there which he conveniently ignores in order to propogate an opinion that has already been done to death in the motoring media.

"Oh, and last time I checked, Mayor of London Boris Johnson was a Conservative MP, and he mentions "the T word" [transport] quite frequently, and I seem to remember his transport policy was instrumental in his election as Mayor. Perhaps Mr Rutherford is looking in the wrong places for his own research.

"Global warming probably didn't kill the dinosaurs, but perhaps Mr Rutherford is worried that environmental issues will wipe out the dinosaur journalists?"

It remains to be seen whether my letter will merit inclusion in the comments section of the magazine, but if it does I'll update the blog with the response, if any. Who knows, I may even receive an email from Mr Rutherford himself.
