Audi traffic light recognition could save 240 million gallons of fuel [UPDATE]

Any hypermiler will tell you that the way you drive your car has a huge impact on how much energy it uses. But these greenfoot drivers haven't had a car that's smart enough to tell them about the inner lives of traffic lights. That's what a prototype system in an Audi A6 Saloon that the German automaker recently tested in Las Vegas can do. Since the car can communicate with local traffic signals and is able to predict when lights will change, the car can help reduce CO2 emissions by up to 15 percent. Further, Audi says that the system could save some 238 million gallons of fuel (900 million liters), if deployed across Germany. We can only imagine what hypermilers could do with this. We got to drive the Audi Online traffic light information system prototype in January, but we focused more on how the system worked rather than the green aspect. Now that Audi has had a bit more time to crunch the numbers, it has released fuel economy information for the connected car. The key points for the eco-side of things are that the driver is told in the dashboard how fast/slow to go to hit the next green light. This can help prevent unnecessary speeding and or encourage drivers to go a bit faster in order to hit the green, thus preventing idling and wasted time. The system is too smart to let you idle for long. Except that Audi Online is too smart to let you idle for long. The Audi connect system can calculate how much longer the light will be red and can access the car's start-stop capabilities and will fire up the engine "five seconds before the green phase." That seems like an awful long time in a world where competitors have figured out ways to restart an engine in 0.35 seconds. We've asked Audi for an explanation on why this buffer is so lengthy, and will let you know what the reasoning is when we hear back. Despite the trials in the A6, Audi says the Audi Online traffic system could be integrated into any Audi model, "subject to the necessary government legislation." Aside from the Sin City tests, Audi is running trials of the connected car in Verona, Italy and Berlin, Germany. If you'd like to test it out yourself some day, take heart from this line in the press release, available below: "A market launch is currently the subject of intense analysis in the United States." *UPDATE: Audi's Mark Dahncke told AutoblogGreen that the five second window is meant, "To alert the driver that the light is about to turn green.

Audi starts new e-gas partnership with Global Bioenergies

Audi continues to try to build its green-car cred with one more partnership to produce synthetic fuels made from renewable resources. The German automaker is hooking up with France-based Global Bioenergies to make a synthetic biofuel called e-gasoline. Audi says making this e-gas "does not create competition with food production and farmland," nipping that argument in the bud. Last summer, Audi opened a power-to-gas facility in Werlte, Germany. That factory produces hydrogen and synthetic methane, which are made from renewable energy sources such as water and excess carbon dioxide. The E-gas plant uses electrolysis to split water molecules into oxygen and hydrogen; those elements will later be set aside to power fuel-cell vehicles but in the near term, the plant will make synthetic natural gas. Audi started delivering e-gas in Germany in the fall of 2013 and estimated that it would make enough of the stuff each year to power 1,500 Audi A3 Sportback G-tron vehicles for more than 9,000 miles. Audi also operates a research facility in Hobbs, New Mexico, with renewable fuel company Joule. That plant produces e-ethanol and e-diesel. Check out Audi's press release about its new Global Bioenergies partnership below. Audi launches strategic partnership with Global Bioenergies Premium carmaker and biotechnology company developing the drop-in biofuel Audi e-gasoline Reiner Mangold, Head of Sustainable Product Development: "Another step closer to carbon-neutral mobility with Global Bioenergies" e-gasoline part of the big Audi e-fuels strategy Audi is launching a strategic partnership with Global Bioenergies. The carmaker will work with the French biotechnology company to promote the development of non-fossil fuels. In addition to the Audi e-gas and e-diesel projects, the research into e-gasoline is part of Audi's persistent efforts to find alternative fuels. Reiner Mangold, Head of Sustainable Product Development at AUDI AG: "We're taking another step closer to carbon-neutral mobility with our partners at Global Bioenergies. We are supporting an innovative technology here which can be used to produce renewable fuel. This process does not create competition with food production and farmland." e-gasoline is part of the overall Audi e-fuels strategy. Audi is already operating a research facility for the production of e-ethanol and e-diesel with its partner Joule in Hobbs, New Mexico. The Audi e-gas plant in Werlte began feeding into the grid a few months ago.

Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.
