Toyota Prius 2011 News

The new hybrid hero is not technically part of the Prius family, but Toyota is using its TS 030 as a 320km/h labratory-on-wheels and a way to break down barriers against future cars. Toyota is not planning to win in France this year but does intend to lay the foundations for future success at Le Mans with a two-car coupe entry in full factory colours. But it will not be the only hybrid contender in June, as Audi has just confirmed plans to race a pair of diesel-electric versions of its latest R18 in a four-car effort at Le Mans. It is believed to use a flywheel, similar to the Williams F1 system already used by Porsche in a racing 911, for energy storage. The new Toyota 030 is also a full hybrid that combines a 3.4-litre V8 racing engine with a hybrid energy storage system to boost power to electric motors at the wheels. The biggest difference between the road and race cars is the storage system - a Prius uses a battery pack and the Toyota racer uses a high-tech capacitor that has greater storage potential and the ability to release energy in a more concerted burst. "The first year is a testing year, but at the same time, the whole team, including myself, has massive motivation. Even if it is the first year, we are there to win the race," says Kazuki Nakajima, a former Williams F1 driver who heads the driver lineup for Le Mans. Toyota has fielded cars many times at Le Mans, firstly with the TS 010 and 020 that made the podium in the 1990s, then the GT-One built in Germany by the team that would eventually take Toyota - unsuccessfully - into Formula One. The 030 hybrid has already been tested extensively ahead of Le Mans but Toyota says it is still assessing the potential drive system. Race rules mean a maximum of 500 kiloJoules of energy can be recovered under braking - although the capacity of the Toyota system is double that amount - and it can be fed to either the front or rear wheels. rand Prix cars use their kinetic energy recovery systems to boost drive to the rear wheels but Porsche has turned its 911 into an all-wheel drive racer with electric power to the front wheels, something also being trialled by Toyota. The Toyota 030 hybrid races for the first time at Spa in Belgium in May and, apart from Nakajima, the six-driver lineup also includes former F1 racer Alex Wurz.

Cheap and green is the name of the game, with the Yaris aiming to deliver the least expensive hybrid in the market, with the best fuel economy and emissions figures in the light car segment. Rather than relying on the 1.8-litre engine from the Prius, Toyota has downsized to a 1.5-litre and a smaller electric motor, inverter and battery pack, saving about 20 per cent in weight and avoiding having to cannibalise the Yaris cabin and 286-litre luggage space. The new system is tipped to deliver a maximum of 74kW with fuel economy nearing 3L/100km and emissions as low as 80g/km. This brings it under the Prius’ 3.4L/100km and 89g/km, and also makes it a contender against new ultra-light city cars such as the Volkswagen Up. Initially slated for Europe, the Yaris will make its international debut at Geneva Motor Show in March and hit the showrooms over there by May. And it will eventually hit our shores, but don’t expect to see it here for some years, Toyota Australia says. “For the Australian market we have the Prius C arriving towards the end of first quarter this year – within a couple of months -- and that will take the spot of the Yaris Hybrid here,” a Toyota spokesman says. “That’s for the interim. (TMC boss) Akio Toyoda’s vision is that every Toyota model will have a hybrid variant by 2020, so by then we will have one.” As the first full hybrid model in the B segment in Europe, Toyota’s newcomer will hope to build on the strength of Yaris being their top seller there – and snare younger buyers that can move up the model line as they mature.

M.I.G. Security relies on its nine-strong Toyota Prius fleet for security patrols around Mandurah and surrounding areas, about 75km south of Perth. Operations manager Paul Hiron said the longest-serving Prius, which has been used for patrols since 2005, is still going strong after 788,411km. Hiron says reliability is vital to their business as clients depended on the company to give them peace of mind. "Prius is ideal for our work, being quiet, economical and comfortable," he says. "It's ideal in stop-start traffic for fuel-efficiency and it performs on the open roads as well."

The US state has authorised the development of rules and regulations governing the use of driverless cars - such as Google's concept car - on its roads.And while these auto-pilot automotives may be still some way down the track the move by the legislators has been welcomed in some circles as an important step toward the future of motoring.Nevada - home to other great gambles such as Las Vegas and Reno - also has a lot of open space and deserts so the driverless cars can be tested with room to move.Internet giant Google has tested auto autos in California over 220,000km but these have carried two people - someone monitoring the gear and another behind the steering wheel in case of trouble.It's claimed cars without drivers would reduce fuel consumption and accidents. Some see the machines used for goods deliveries or taxis.But could you be pulled over after a long night at the local honky-tonk?

Feedback from show patrons will help determine whether the production version of the Prius c Concept is headed to Australia. The Prius c Concept is the inspiration for a future small hybrid with an entry price point and superior fuel economy. If approved for Australia, the city car will join the iconic hybrid Prius brand, broadening its appeal. Toyota Australia senior executive director sales and marketing David Buttner said the urban appeal of cars such as the Prius c would further increase the acceptance of hybrid cars in the market. "This car has the core Prius values based on Toyota's proven Hybrid Synergy Drive technology  strong performance, great fuel economy and ultra-low emissions," Mr Buttner said. "We are bringing it to the Australian motor show to test its appeal among buyers who we expect will come from a different group to those attracted to the current Prius. They are compact-car buyers, including young singles and couples, who want a mainstream city car that provides outstanding fuel economy while being fun to drive." The Prius c Concept, unveiled at this year's Detroit auto show, provides a surprisingly spacious interior in a compact package. It will include many advanced technology features, including some offered on the current Prius. The production car is due to be launched in the US during the first half of 2012. No timing has been announced for a possible Australian introduction.

And each week it seems the fuel price sign goes up faster than a politician's pay packet. Australians use a vast amount of fuel in going about their daily business, be it getting the kids to school, travelling to and from work, or conducting the nation's business.Each year we import an ocean of petrol, diesel and LPG that's equivalent to 63,000 Olympic swimming pools. And we're not alone, as the vast populations of newly mobile countries such as India and China take to the roads in their Tatas, Great Walls and Cherys, the world's thirst for oil seems ever more insatiable.Overlay this with war and unrest in the Middle East, the source of 56 per cent of the world's oil, and the inevitable push-pull dynamics of supply and demand can lean to only one thing: higher fuel prices.Here in Australia motorists have been feeling the pinch of higher fuel prices since January when the latest spike in oil prices first began appearing on service station leader boards.The spiralling petrol prices mean fuelling a family car like a Commodore or Falcon now accounts for 2.6 per cent of average weekly earnings. But you don't have to sit back and take it in the hip pocket. There are ways to drive down your weekly fuel bills. Here are a few of them.DOWNSIZING According to VFACTS industry statistics, this seems the most popular choice. Large cars have gone from the top-selling passenger segment in 2000 with 198,766 to the smallest passenger segment last year with 98,583 and falling at 3.1 per cent.Meanwhile, sales of smaller cars are skyrocketing. In the past 10 years small car sales have almost doubled to 239,191 while light cars have increased about 44 per cent to 137,916. You can buy a small car from as little as $11,990 (plus on-road costs) for the Chinese-made Chery, right up $35,990 for a Citroen DS3.And you won't go without. Some of the cheapest little cars these days come with a swag of safety and creature features from multiple airbags to Bluetooth connectivity.PROS: Save on fuel; do the environment a favour; easier to park; nippier in traffic; little hatches can be cavernous if you fold down the rear seats.CONS: You get cramped on long journeys; they are noisier on the highway; they're bumpier over potholes; you could feel a little silly driving a Smurf car.Our Pick: Hyundai i20 (from $15,490) is set to take over from Getz as the segment leader with Euro styling and a high level of features and safety.Others to Consider: Suzuki Swift (from $15,990), Mazda2 (from $15,790) and Toyota Yaris (from $14,990).DIESEL Like smaller car categories, the growth in diesel-powered vehicles is exponential. Since the Federal Chamber of Automotive Industries began collating separate figures for various fuel types in 2005, diesel cars and SUVs have more than doubled to 125,555 last year, which is almost one in every five new passenger cars or SUVs bought today.The reason is that modern diesel engines are not only up to twice as frugal as a petrol vehicle, but they often have lower emissions because they burn less fuel per kilometre and usually have an exhaust system that traps small carbon materials.Modern diesels are also quieter and smoother running. However, diesel engines have higher internal pressures and a complex fuel system so they are more expensive to build than a petrol engine. Some car companies charge up to $10,000 more for a diesel variant, although most charge around an extra $2000.Expensive diesels are often the result of low production volumes and highly technological designs and machining costs. To reap the economic benefits you have to drive big kilometres each year and hold on to the vehicle longer.An extreme example is the Holden CD Cruze auto diesel that costs $4000 more than the petrol model. Based on RACQ's fuel running costs of 9.36c/km for the petrol and 8.41c/km for the diesel, you would have to drive 25,000km for 16 years to recoup the extra cost.PROS: Fuel economy is anywhere between 10-50 per cent better than a petrol equivalent; more torque means quicker acceleration and easier driving around town; better towing capacity; marginally better resale value; lower CO2 emissions per kilometre; diesel engines often last longer because of the more robust engineering.CONS: Fewer diesel pumps on servo forecourts means queuing at the servo; oily bowser pumps leave your hands smelly and dirty; the engines still clatter at idle and sound raucous at full revs; it takes a long time to reap the economic benefits; servicing charges can also be more expensive because of the more expensive oils required and the complicated fuel systems.Our Pick: Fiesta ECOnetic (from $24,990) is a hybrid beater even in stop-start commuting, yet it's a delight to drive.Others to Consider: Hyundai i30 (from $23,090), VW Golf (from $29,990), Subaru Forester (from $35,990).LPG It's almost worth it to convert your petrol or diesel vehicle to LPG just to get the $1500 Federal government subsidy. But you better be quick because the conversion rebate drops to $1250 from July 1 and decreases $250 annually. All rebates and subsidies are only for private vehicles.Conversions cost an average of $2800 for pre-2006 vehicles, but about $4000 for newer vehicles because of emissions regulations. If you buy a vehicle factory fitted for LPG before its first registration, you get a $2000 rebate from the Feds.However, choices of new vehicles with factory fitted LPG systems are limited. Ford has a new LPG Falcon coming in July and has factory-fitted systems for some of its utes. Holden has an Autogas dual-fuel injection system for its Commodore and will have a mono-fuel LPG Commodore later this year.Toyota has a direct injection LPG system for its 2.7-litre HiAce vans and Mitsubishi has an aftermarket sequential multi-port direct-injection system for its Challenger, Express Van, Pajero, Triton and the now defunct 380.PROS: Much cheaper fuel (about 60c compared with $140+ for ULP); government subsidies make conversion attractive; LPG prices are fairly static so you don't have to fill up on a Tuesday morning when servo prices are cheapest; lower emissions.CONS: Limited choice of new dual-fuel vehicles; only suitable for large vehicles; you lose boot space; even though they are safe they can develop minor smelly leaks; they add about 75kg (about the weight of two large suitcases) to the rear of the car effecting handling; it can be difficult finding servos with LPG in rural areas.HYBRID These are vehicles with petrol or diesel internal combustion engines paired with an electric motor or motors. The drivetrain and associated battery pack for the electric motor is more complex so therefore more costly. Like diesels, you need to do big kays before the savings at the bowser recoup the extra purchase price.For example, a Toyota Prius costs about $2500 more than a Corolla Ultima. Using RACQ's running costs, the fuel savings will take 4 years at 15,000km a year (or 2.5 years at 25,000km/year) to recoup the extra purchase price.Most hybrids switch off totally every time you stop and run on electric power only when you are driving slowly, so they are most economical in heavy traffic. The benefits are marginal on country roads and highways, although when both drive units are operating under heavy acceleration such as when overtaking, they do offer a tangible boost to acceleration.Despite the fact the technology has been around for 10 years, Hybrids are still relatively new. Today, there are 10 hybrid models on the market, but only the Toyota Prius, Camry, Honda Insight and Civic are affordable.Hybrids tend to be bought mainly by governments and big business to emphasise their green credentials. Taxi companies also like hybrids because of their fuel efficiency in urban environments. If you're open to the idea of a used vehicle, then a second-hand Prius or similar is a reasonable option.PROS: Cheaper to run in traffic; feel and be seen to be environmentally conscious; extra power under heavy acceleration; almost silent running when on electric only power.CONS: Higher purchase price; the number of models is limited but you can choose from a small Prius to a large Porsche Cayenne SUV; some look odd like the Prius and Insight.Our Pick: Toyota Prius (from $39,900) and the Honda Insight (from $29,990) at least look like futuristic hybrids, so your neighbours will know you are trying to be green.Others to consider: Honda Civic (from $34,490), Toyota Camry (from $36,990)ELECTRIC CARSThe only production electric cars in Australia are the Tesla Roadster at $241,938 and the Mitsubishi i-MiEV which is available only on a lease of $1740 a month for three years for a total of $62,640. Then the car goes back to Mitsubishi. When it arrives it is expected to cost $70,000.However, prices will come crashing down in the next few years as more and more EVs become available in Australia. The first of these will be the Nissan Leaf and Holden Volt next year.The Volt is expected to cost less than $40,000 and Nissan is saying the Leaf will cost about the same to run as a Tiida, even though initial outlay will probably be close to the Volt. While tailpipe emissions are zero, most electricity in Australia comes from burning dirty coal, so the environmental advantage is reduced.Some critics say there is no advantage. Current limitations of battery technology mean range is also limited to about 160km according to the car companies, but in real life it's less, especially if you have a lead foot.PROS: Very cheap to run; no tailpipe emissions; almost silent running; aerodynamic body shapes.CONS: Expensive to buy - that's if you can find one to buy; silent running can be dangerous for pedestrians; battery disposal is an environmental issue; range is limited; long re-charging time (up to eight hours); most EVs are designed to look futuristic but just end up looking like golf carts.DRIVE ECONOMICALLYOf all the things you can do to drive down your fuel bill, this is the most pragmatic as it's the simplest and most affordable. It can be expensive to swap your trusted and much-loved family car or SUV for something smaller or with an alternative powertrain.Trade-in prices on family cars are down according to the Motor Trades Association and if you buy a new car, you are up for dealer delivery charges, stamp duty and registration. It may be cheaper to hang on to your vehicle, but modify your driving behaviour for more economical running.There are many simple things you can do: Plan trips better and make fewer trips; jettison excess weight from the car; correctly inflate your tyres and get your car serviced more frequently.Most importantly you can vary your driving behaviour by slowing down, changing up the gears sooner, avoiding heavy breaking and staying away from peak-hour traffic. You may have heard these all before, but here are five radical ideas to reducing your fuel expense burden that you may not have heard.1. Cool idea: Turning off the airconditioning will provide a slight increase in fuel economy. However, when travelling on the highway, it is more fuel efficient to have the windows up and aircon switched on than having the windows down creating aerodynamic drag. Don't leave the aircon off for long periods as bacteria will build up in the system.2. Light is right: So throw out not only the unnecessary baggage such as your golf clubs, but maybe also the spare tyre. It can weigh 15-20kg in the average car. The US Department of Energy quotes fuel use as 1-2 per cent for every 45.5kg, so that's at least 0.5 per cent saved. Conversely, NRMA tests show that loading a vehicle to its rated maximum increases fuel consumption 24 per cent. While you might be able to get away without a spare tyre around town, we recommend you always carry it on long trips, especially in the country.3. Turned off: Switch off the engine at long traffic light stops. Modern fuel-injected cars start quickly without the need for any throttle. Car makers with stop-start technology that automatically switches off the engine every time the car is stopped quote fuel savings in traffic of 4-5 per cent.4. Just cruising: Use cruise control more frequently. Most cruise control systems actually put the car's engine into an economy mode and will run more efficiently than most drivers can drive as it accelerates more evenly. It is best used on the open road and not hilly terrain or stop-start conditions. While we could not find any official figures, some sources claim fuel savings up to 14 per cent.5. Re-tyre: the next time you buy tyres, choose from the new range of "eco" tyres with low rolling resistance. A California Energy Commission study estimated low-rolling resistance tyres could save 1.5-4.5 per cent on fuel consumption.

The spiralling petrol prices mean fuelling a family car like a Commodore or Falcon now accounts for 2.6 per cent of average weekly earnings. But you don't have to sit back and take it in the hip pocket. These families have all taken different approaches to reducing their fuel bills.DOWNSIZINGTheir 2000 Falcon was costing the Andrew family of Brisbane a small fortune to keep running, so they decided to downsize.However, instead of buying one vehicle, they went for two Suzukis, the cutesy Swift and the three-cylinder ultra-frugal Alto.Warren, 47, says the Falcon had a 65-litre tank while the combined tanks of the Swift and Alto are 77 litres. "We now get twice as many kilometres from the same expenditure on fuel," he says. Though it has to be noted that the additional cost of registering and maintaining a second car would probably offset any real cost advantage.His wife, Karen, 43, says having two small cars is more versatile for transporting their children Jess, 12, and Emily, 10, to and from primary and secondary schools. We don't miss the Falcon in the least; maybe we will when we go on holidays," she says."It's been great. Having the two cars means we can take a child separately - one to primary and one at high school. The Swift is really cool. The Alto is a good little runabout but I enjoy driving the Swift. We drive whoever's car is at the back. Warren tends to take the Swift. I think he deliberately leaves it at the back."We fill them with petrol every couple of weeks and we can squeeze into smaller parking places. "Jess and Emily love the cars more than the Falcon. They say it's my car'."LPG Retirees John and Lesley Braggs planned to become grey nomads so they bought a 2003 BMW X5 V8 petrol a few years ago. "You wouldn't get much change out of $120 when you filled it up," he says.About eight months ago they converted it to a dual-fuel petrol/LPG system. "We were travelling around a lot going down to Melbourne and back and have plans to travel to Adelaide and Alice Springs," he says."We only put about 20 bucks a month of petrol into it because it starts up on petrol and then a few seconds later the gas kicks in. "The petrol also kicks in if you run low onLPG but we never run low and need to use it. I only ever have about a quarter of a tank of petrol, otherwise it's excess weight we don't need."He says he hasn't noticed any change in performance. "It seems to have the same amount of power as when it's running on petrol I reckon," he says. They had a 70-litre LPG tank installed where the spare tyre was located under the cargo floor so they didn't lose any luggage space. "I carry around a pressure pack in case we have a puncture," he says.The LPG installation cost about $4500 with the government rebate. "I'm really wrapped with it. There is nothing different with the performance and it's cheap," he says."LPG is currently about 70c a litre. When we first got it, it was about 40c a litre, but it's still cheap."HYBRID The Knights have discovered another benefit of their fuel-efficient Toyota Prius with the recent birth of their son, Thomas."Now that we have the baby we don't have the radio on and we can tell how quiet it is," Tanya says. "It's a bit disconcerting sometimes when it kicks into electric." Tanya and husband Stephen bought the Prius two years ago."We were in the market for a new car and wanted to be as fuel efficient and environmentally conscious as possible," she says. "We came from a Falcon with LPG so I didn't want to go to a petrol car and pay X number of hundred dollars to fill it."We found the LPG wasn't particularly fuel efficient. It guzzled the fuel, but it was half the price. "Now I fill up maybe once every three to four weeks on a 60km daily round trip to school and home. "With highway driving, I can get over 1000km on one 40-litre tank of fuel which is amazing. We're really happy with it and wouldn't go to a petrol-only car ever."Mrs Knight says the Prius is a bit quirky in design and function. "But once you get used to it, it's interesting," she says. "People are astonished. They say the car has turned off."She also defends the Prius as a family car. "It's actually a reasonable size car. We get the baby capsule in and there is plenty of space for other people, she says. "My dad used to run taxis and many in the industry are going to hybrid cars."DIESEL The Webbs were a bit skeptical about diesels when they went to test the Hyundai i30cw CRDi wagon. But Adam and Katie Webb of Brisbane were pleasantly surprised. "My only experience of a diesel was my mate's old diesel HiLux which chugs and smokes," says Adam. "I had done some research and knew a bit about the new turbo diesels but my wife was especially concerned about the noise and smoke of them."However, when I took it for a test drive I was surprised. For a 1.6 (litre engine) when you put your foot down it really takes off. "It's really quiet. Especially on the highway you hardly notice you are driving a diesel. "There's still a bit of noise when you start it up. You know it's a diesel, but it's a lot smoother and quieter than we thought."The Webbs traded in their 1996 Magna wagon three months ago. "We pretty much downgraded in size, but there is still plenty of space," he says. "Me, my wife and the two kids all fit in quite well and when you have a couple of kids their stuff takes up a lot of boot space."The burning question is fuel economy. "We bought it just for the fuel efficiency," he says. "I'm not too sure on the actual economy figures but we drove about 600km to Rainbow Beach and back last weekend and there's still about a quarter of a tank left."He rejected concerns about limited and dirty diesel bowsers. "My wife drives it more than I do and she hasn't had any problems finding a boswer," he says. "Hyundai supply 10 disposable gloves with the car to use when filling up, but we've never used them."

Toyota's eco-friendly but buyer-cool Prius hybrid was the first to slash its price, down between $5000 and $7500 depending on the model.  Effective immediately, Prius is $34,990 and the upmarket i-Tech version is $45,990.Toyota Australia says the substantial drop is in answer to its hybrid technology becoming more popular. Indeed, global Prius sales have exceeded a pleasing two-million units but in Australia, sales have totalled a relatively minor 16,000 since inception.It has recorded a 63.7 per cent year-to-date plunge for 2011 compared with the same period in 2010 despite total hybrid private buyer passenger car sales almost doubling. It is believed the Toyota Camry Hybrid has taken a large slice of the Prius market.Toyota Australia doesn't believe Prius buyers are disadvantaged by the price cuts.  Its sales and marketing director, Dave Buttner, says Toyota Australia has offered "substantial cost-of-ownership benefits for a considerable period through low-interest finance, in anticipation of official approval for the price repositioning"."Customers who have taken advantage of these offers to buy a Prius from our dealers over many months have made substantial savings and are certainly not disadvantaged."National passenger car sales slipped 4.1 per cent in March on a year-to-date basis and down 6.5 per cent on March 2010. Some big losers included the Ford Falcon, Volvo V70 and S40, VW Passat Mazda RX-8 and BMW 3-Series, the latter down 31 per cent on the same three-month period in 2010.Coincidentally, BMW has taken a knife to the prices of its 3-Series models with cuts of up to 11 per cent.  It says the "sharpened pricing" is "a celebration of what has been the world's most successful premium model series".Price changes affect the 3-Series sedan, wagon, coupe and convertible models. The 325i gets the biggest discount, falling $9100 (11 per cent) to $71,900 from $81,000 previously and at the same time, picking up the "Exclusive Innovations" pack with an upgraded sat-nav, voice control and bi-xenon headlights.The M Sport version of the 325i sedan is also down 11 per cent, now $76,700 with a similar $9100 saving.  The 3-Series 325i Convertible with the "Innovations" pack is $9500 cheaper at $94,600.Toyota's price cut aims to create greater acceptance of hybrids. The company is licensing its technology to other car makers.  Toyota's Dave Buttner says new hybrid models "will revitalise the market and help to make eco-cars in general more popular"."A key factor in lowering the cost of any advanced technology is market acceptance, leading to strong sales," he says.  "The more popular hybrid cars become, the more affordable their prices and, therefore, the greater the impact on the environment."

The latest generation of grand prix cars are petrol-electric hybrids that also use a range of high-tech systems and technologies, right down to long-life oils, that will eventually find their way into everyday road cars.An F1 hybrid is very different from a Toyota Prius, since braking energy is stored and released for a burst of speed and not for low-speed electric driving, but the work done on high-tech batteries and computer control systems is easily transferred to production line heroes.It's typical of grand prix technology transfer, which has been a reality in racing for decades. Still, it's ironic that some of the most advanced safety features in road cars - ABS brakes and ESP stability control - are banned from Formula One and there is no way yet to adapt airbags to the violent and unpredictable crashes in grand prix races.Tracing the F1 roots of today's road cars is relatively easy, starting with engine and gearbox technology from the 1990s. Honda developed and refined the V-Tech adjustable camshaft timing that combines power and economy in racing and Ferrari led the world into the era of robotised manu-matic gearboxes."V-Tech technology came directly from Formula One. At the time it was new to the Honda V10 engine used by McLaren, but now it's on every road going Honda car, right down to our economy cars and hybrids," says Mark Higgins of Honda Australia.Current F1 cars used gearboxes which have a 'seamless shift' system that's similar to the double-clutch gearboxes fitted to growing number of cars, including the Volkswagen Golf. Aerodynamics and high-tech materials are two other important areas.Carbon fibre is starting to find its way into top-end sports cars, including the Lexus LF-A supercar, after being adapted from aerospace to racing. McLaren was the first to do the job and now the ultra- strong composite is universally used in F1 and being adapted to lightweight city cars of the future.A range of other 'on the aero' front, this year's grand prix cars have a driver-adjustable rear wing - a long way ahead of the 1950s 'air brake' used by Mercedes-Benz at Le Mans - and that technology is coming fast for road cars.Ferrari has aerofoils in the nose of its latest 458 Italia that change shape at various speeds to assist cooling and downforce. In future, 'active' aero systems will blank the front ends of road cars at speeds to cut drag and improve fuel economy - then open again for cooling when the car is stopped in traffic. This sort of work is also made easier by the complex artificial wind tunnels contained in F1 computers - the programs are called Computational Fluid Dynamics - used to test and develop new body parts.Ford recently credited CFD work on the upcoming Ranger pickup and almost every major maker uses CFD for early design and development work. Even F1 fuels and oils are used for road car work, with Shell trumpeting the V-Power development it did with Ferrari before introducing its current flagship fuel. And it has used grand prix engines for decades to test the oils which now allow road cars to run for more than 10,000 kilometres between changes.

Then we head north in a Holden Cruze and Mitsubishi ASX, looking to see how far this pair can go on a single take of fuel.  Ed Ordynski is in the ASX and I have the Cruze, holding  the trip computer just over 6 litres/100km as Ordynski - expert driver - is below 5 litres/100km.The first stop is just outside Port Pirie after 250 kilometres and the figures are 5.3 and 4.2, as we battle wind and rain.  A lunch stop in Waikerie - about 530km into the journey - and then a turn south to follow the Murray both cars maintain sub-6 readings - the ASX in the region of 4.5 and the Cruze 5.5 litres per 100km as we pass the 700km mark near Murray Bridge.The weather worsens as we follow the river south through 730km at Wellington."The ASX was more adversely affected by that, it was 0.3 litres/100km worse off - we did what you need to do into a headwind and that was reduce the speed a little," Ordynski says.Running down through the southern foothills to complete our 1000km journey we return the tanks to full. There are still 15 litres in the Mitsubishi's 60-litre tank, but my Cruze is almost on fumes.  But after thirteen hours of "real-world" driving we have hit our 1000-kilometre target."I would drive like that with people on board and not be embarrassed," Ordynski says.  "You win on fuel use and emissions as well, with 2kg of CO2 for every litre of fuel, you win on maintenance and longevity of the vehicle by driving it kindly as well, it's hard to see a downside."Ed Ordynski’s Fuel TipsLevel 1. Overall factors1. Plan when you need to use your car to avoid unnecessary journeys.2. Plan your journey to avoid peak hour and congested roads.3. Measure your fuel consumption and take pride in reducing it.4. Choose an energy efficient vehicle.Level 2. Anyone can try1. Concentrate on driving smoothly and anticipate traffic flow to conserve momentum.2. Keep tyre pressures at maximum recommended.3. Avoid any excess weight in the vehicle and remove accessories which affect the aerodynamics (e.g. roof racks).4. Choose a manual transmission and learn to drive it properly for optimum fuel efficiency.Level 3. Hard-core methods1. Avoid use of airconditioning and keep windows closed.2.
