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.

Recharge Wrap-up: New and old Audis get greener, as does US electricity

Audi has made environmental improvements to the its TT while boosting performance. The new TT sees an 11-percent reduction in emissions, and up to 14 percent more power. Audi says that each TT will save around 5.5 metric tons of greenhouse gas emissions over its lifecycle. Additionally, the TT's manufacturing process has been cleaned up a bit, reducing emissions by about nine percent. Read more in the press release, below, or see Audi's lifecycle assessment here. Speaking of greening up Audis, Al Swackhammer of Washington converted his 1960 Audi DKW 1000S to run on electric power. Swackhammer first fell in love with the Audi Ur-Quattro, became an enthusiast of Audi and Volkswagen cars, and has owned nothing else ever since. With his DKW, he combined his passion for the classic car with his responsibility to the environment. "I am pleased that I did this project," says the happy owner, "and I enjoy driving it very dearly." Meet the man and his beloved electric Audi DKW in the video below. Toyota has chosen a sustainable design firm, Corgan, as the lead architect for its new North American headquarters. The new campus will be built in Plano, TX, and will be the workplace of about 4,000 Toyota employees. Corgan, who has already done 47 LEED certified projects, is already designing a temporary office for the site while it finishes the project. Toyota expects to begin working from the site in late 2016 or early 2017. Learn more in the press release below. In July, all new electrical generating capacity in the US came from renewable sources. The Federal Energy Regulatory Commission's Office of Energy Projects' newest "Energy Infrastructure Update" report says new electric generation put into service last month came from wind (379 megawatts), solar (21 megawatts) and hydro (5 megawatts). So far this year, 53 percent of new energy generation capacity has come from various renewable sources, and none from coal or nuclear. Currently, renewable energy accounts for 16.3 percent of the US electric generation capacity, providing about 14 percent of actual electricity.

Positive life cycle assessment for the new Audi TT Compact sports car scores high for dynamic performance and efficiency Emissions reduced by 11 percent compared with predecessor Customer benefits from the very first mile Ingolstadt, August 18, 2014 – Dynamic performance and efficiency: The new Audi TT* impressively combines both qualities.

Audi shows off the Prologue Avant Concept as a plug-in hybrid

The Audi Prologue Avant Concept goes in a different direction than the Prologue coupe, in more ways than just its five-door wagon body. The coupe was first shown at the LA Auto Show with a 4.0-liter, twin-turbo V8, then went redux at CES as a hybrid with a total of 677 horsepower and 701 pound-feet of torque. The only-slightly-larger Prologue Avant sticks with the hybrid but gets the system from the Q7 E-Tron quattro, meaning a 3.0-liter, twin-turbo V6 TDI with 353 hp and a 100-kW electric motor strapped to the eight-speed transmission. Total output is 455 hp and 553 lb-ft, pure electric range is 33 miles, and 0-62 miles per hour comes in 5.1 seconds. The forward section of cabin with its screen-based Tie Fighter displays and controls comes over from the coupe, as well as the four individual seats, but the Avant lavishes attention on rear passengers in ways not possible in the two-door. They also get a screen on the pass-through center console for convenience controls, and detachable OLED screens - a la the detachable tablets in the Q7 - with which they can send information to the front occupants. As a traditional Audi avant is to a coupe relative, the Prologue Avant is all about bringing the family along on the digital highway. We'll see it at the Geneva Motor Show next week, and Audi is again talking up how the design language will migrate to production cars. It also makes noises in the press release below about near-production many of the technologies are in the concept, so it looks like there could be all sorts of Easter Eggs on the way from the Ingolstadt brand.
