Volkswagen 1-litre concept one step closer

News arrives via AutoBlogGreen that Volkswagen's 1-litre concept is still under development and nearing production reality.
The concept, now being named the L1, will be on display at the upcoming Frankfurt Motor Show and Volkswagen have released more details about the car and the engine that will be powering it in a press release that you can read in full on ABG's page.

The 1L has a 0.8 litre TDI developed from Volkswagen's new 1.6 TDI that makes its debut in the new Golf and Passat BlueMotion. Along with automatic stop-start, a 0.195 coefficient of drag and thanks to an all-in weight of only 380kg, the 1L is claimed to sip one US gallon of fuel every 170 miles, or 204mpg imperial (and only 36 grammes per kilometer of CO2). This works out at a little over the original 1l/100km that Volkswagen claimed, though I'm sure owners wouldn't complain as the eventual figure is still only 1.38 litres per 100km. Thanks to the light weight and slippery shape, the 1L also manages 100mph.
Volkswagen are now giving the car a tentative 2013 release date. Should give you time to save up...

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...

Renault's ZEs... driven by Autocar, confirmed for production

Renault will be the first major car manufacturer in the world to offer a range of zero-emissions all-electric vehicles for sale when the Twizy and Zoe go into production in 2011.

The French manufacturer is taking quite a risk given that this will leave many countries with only a short space of time in which to set up a reasonable electric charging infrastructure, though according to Autocar magazine who feature the three Renault ZE concepts this week, Israel and Denmark have both made commitments to importing 100,000 electric Fluence models by 2012. Renault will be establishing a network of "Quickdrop" centres (areas where ZE customers can take their car to have the entire battery unit changed for a fully-charged on in around three minutes) in these countries.

The Twizy

The Twizy microcar is the smallest of Renault's ZE (Zero-Emissions) concepts and has been confirmed for production in Spain in 2011. The car/scooter is a tandem two seater and is designed solely for city driving, with performance similar to that of a 125cc scooter (topping out at around 50mph). Range is short at roughly 60 miles, but realistically you don't need any more than that in a city commute and even in a city like London you should be able to get at least a couple of days' commuting out of it. As you can see in Autocar's video above, the Twizy is apparently quite fun to drive.

The Zoe

The Zoe is supermini-sized (only slightly larger than a Clio) though unlike the Twizy and the larger Fluence, the styling might well change significantly for production. Renault say the Zoe is more representative of what can be done in terms of size. Range is around 100 miles and the motor makes the equivalent of 95bhp giving a 90mph top speed.

The Fluence

Looking more production-ready than either the Twizy or the Zoe is the Fluence. Styling-wise it shares hints of Renault's 2005 Fluence concept as well as a hint of Tesla Model S. However, it's likely to look much more similar to the production petrol and diesel Fluence that appears to be replacing the old Megane saloon. The concept has the same powertrain as the Zoe and shares similar performance and range.

Renault are clearly taking a large risk putting four EVs on sale at the same time (the fourth is an EV version of the current Kangoo van) but this may well be the kick other manufacturers (and indeed customers) need to embrace electric car technology. We await 2011-12 eagerly to see if customers are ready to take the plunge...

Prius (Priuses? Prii?) breaking the 300k mile mark

I was going to use this post to mention the new eco-star from the LA Auto Show, Volkswagen's Up! Lite, with it's headline 70mpg/84mpg (US/UK). Though the regular Up! will go on sale in 2011 however, there is still no confirmation that the Lite, which looks very much like the L1 concept +2, will make the cut. Until we find out for sure, I'll leave the speculation to the bigger motoring blogs and simply furnish you with a few photographs of the Lite:

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 on the original battery set. This will no doubt upset those who believe that big off-roaders like Hummers and Jeeps are greener over their life-span than a Prius because they last longer (even though this was disproven, unsurprisingly, not long after).

It seems like hybrids can last for a while, which is reassuring news for those wishing to buy one second hand, now that used prices are quite tempting (in the UK, early Prius and Civic IMAs seem to be going for little over £3k now). Of course, you should always buy on condition, but it appears that a well-maintained hybrid can easily last as long as any other car - and it's worth bearing in mind that hybrid drivers aren't likely to work their cars too hard...
