New VW Touareg sheds 200kg

Following in the Polo's footsteps, Volkswagen has revealed that the next version of their Touareg will shed as much as 208kg in the base model and offer up to 20% improvements in economy.

The weight saving amounts to as much as 10% removed from the kerb weight of the previous Touareg, and coupled with improved aerodynamics and updated engines, including a new hybrid motor, the new Touareg promises to be one of the most efficient large SUVs on the market.

According to Volkswagen's press release (available on ABG), the new Touareg also offers more space, more equipment (including stop/start technology) and more off-road biased options packages. Visually, the new car shares Volkswagen's family face first seen on the Scirocco, and it works well with the slightly more chiselled body, making the car look much smaller and more dynamic.

Of course, the weight savings on the Touareg will be reflected in the upcoming Audi Q7 and Porsche Cayenne, which share the same platform. Perhaps Volkswagen's step onto the treadmill will encourage other manufactures to do the same with their larger vehicles - the biggest gains can be found from improving the efficiency of the biggest vehicles.

Most frugal car in the real world? Autocar finds out with a race...

Manufacturers make big claims about their fuel economy figures. Occasionally, even these claims can be bettered, as Toyota's now closed blog for the iQ managed back in January, extracting 72mpg when Toyota themselves only claimed 65mpg. Often though, real-world driving prevents us from extracting the optimum economy from our cars.

Autocar's test then perhaps sheds a little more relevance on achieving high miles to the gallon. Armed with a Ford Fiesta Econetic, a Vauxhall Corsa Ecoflex, an Insight, a Prius, a BMW 116d and a Smart ForTwo CDi, they each hit the track at Bruntingthorpe with a single litre of fuel and a driver trying to achieve as many miles in the hour as possible. By working to distance rather than outright economy, it avoided the whole race becoming a slow eco-trundle.

The most efficient at the end of the hour? Ford's Fiesta Econetic. It achieved almost sixty miles at the hands of Matt Prior, equivalent - unsurprisingly - to roughly 60mpg. A little way short of Ford's 76mpg combined figure perhaps, but much more representative of what drivers can expect in their daily grind, and a long way from shabby.

The other cars in the test all managed to average around 55mpg, including the diminutive Smart despite being driven pedal-to-the-metal until it spluttered to a halt after 53 minutes.

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...

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."

The numbers have it: UK car CO2 emissions are falling fast

If ever there was a sign that times are tough and people are trading down to more efficient cars, it's the sharp reduction in the average CO₂ emissions of cars sold in the UK from 2007 to 2008.

Average emissions have dropped by over 5g/km in the past year, continuing a trend that's seen CO₂ plummet by over 30g/km in the last ten years. 2008's figures show a significant fall however, suggesting that the current economic climate, the spike in the price of fuel last year and purse-strings generally being tightened across the country are resulting in people buying much more economical cars than they may have in more favourable times. The figures have been outlined by the Society of Motor Manufacturers and Traders (SMMT) More of the results are illustrated below.

The trend can also be attributed to the huge efforts that manufacturers have made in recent years too. BMW recently launched their 116d, the most fuel efficient BMW currently available, capable of over 50mpg and with CO₂ emissions as low as 118g/km. Many companies now offer stop-start technology which significantly reduces fuel consumption in city traffic, and companies like Mazda with their 2 and Volkswagen with their upcoming new Polo have worked hard to reduce weight, allowing smaller and more efficient engines to be used without compromising on performance. Volkswagen recently unveiled the new Polo Bluemotion concept at the Geneva Motor Show, which sips a gallon of fuel as infrequently as every 85 miles. It also manages to look very handsome indeed.

With cars such as these, expect the current trend to continue.

Reasons to be happy in '09 - small, fun cars

In the midst of economic gloom and worries about the environment easing us into 2009, at least some car manufacturers still know how to have fun. First to take a bow is Fiat, who bring us news of something we've all secretly been hoping for since the demise of the Barchetta and the reinvention of the Abarth marque - a small sports car. This news comes via Auto Express, who give us pictures (albeit artists interpretations, as far as I can gather) of an agressive looking small coupe/roadster based on the Fiat 500.

This means the car will be front-wheel drive, but equipped with the 1.4 turbocharged motor from the 500 Abarth, exciting performance should be readily available, amplified by the lightweight body and low centre of gravity. Not only that, it's anticipated to deliver 45mpg, so whilst not a smart Roadster in terms of green fun, it's more than adequate. Unlike the Roadster it should also be inexpensive - Fiat are aiming for a £12,000 starting tag. Given that the Fiat 500 shares it's platform with the Ford Ka, could we be in for a possible StreetKa replacement in the future?

Also bringing us a small and economical sports car is Volkswagen. VW have tempted us with small roadsters before, but appear more serious this time, touting their BlueSport concept as a cut-price Porsche Boxter. Whilst not exactly svelte at 1200kg, this is still relatively light by Volkswagen standards and the 178bhp, 350Nm 2.0 TDI engine should have no problem propelling it along, especially through VW's DSG dual-clutch transmission feeding power to the rear wheels.

Unfortunately, though somewhat predictably, you pay VW prices for a VW roadster and it's expected to start at over £22,000, over ten grand more than the Abarth. That said, by Boxter standards it's a steal and you're unlikely to get 42mpg and 113g/km of CO2 from a Boxter.

Giving us open-air fun in a different form is Kia, who presented the Soul'ster at the North American International Auto Show in Detroit. The Soul'ster is based on the new Kia Soul so isn't a dedicated sports car like the others, instead presenting us with a kind of pickup/roadster hybrid. Being based on the normal hatchback, practicality is still a strong point with room for four plus luggage, according to Auto Express. With the 1.6 litre turbodiesel available in the UK-bound soul it should be capable of close to the 55mpg that Kia claim for the regular Soul. Alas, as yet the 'ster is only a concept, but it should raise interest in the production Soul.
