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 A3 G-Tron offers big range, few emissions

Audi is exploring a variety of sustainable transportation technologies beyond the traditional diesel, hybrid, plug-in and electric options, including the compressed natural gas A3 Sportback G-Tron that debuted today at the Geneva Motor Show.
The most interesting thing about this rather innocuous-looking A3 Sportback is that when run on Audi e-gas, the car becomes completely carbon neutral, emitting no more CO2 than was chemically input in this special fuel's production. Audi has already broken ground on a new plant - powered by renewable energy, of course - that uses electrolysis to produce e-gas, which could then be made available through any natural gas distribution network.

Audi, Toyota land on MIT's list of 50 Most Disruptive Companies

MIT Technology Review, a magazine all about innovation, has announced its list of the 50 most disruptive companies in 2013, and both Audi and Toyota made the cut. While the term "most disruptive" may carry a negative connotation in most uses (especially in the classroom), the acknowledgement in this case is an accolade, signifying that the company is at the forefront of its industry. In a nutshell, a disruptive company is a business whose innovations force other businesses to alter their strategic direction.
Audi made the list for "pushing autonomous cars closer to fruition with a laser-scanning road detector that fits in a vehicle's front grille," and Toyota for "expanding its dominance of the hybrid-car market with its new plug-in version of the Prius."
