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.

Mercedes chief invites Audi, BMW to compete in F1

Mercedes-Benz didn't just win the Formula One World Championship in 2014 – it positively dominated it. The team won all but three of the grands prix this season, scoring a one-two finish at more than half of them and landing at least one car on the podium at every race without exception. It goes without saying, then, that the German automaker thrives on competition, but now it's welcoming even more. Speaking with Germany's Sport Bild at its homecoming celebration in Stuttgart, Daimler chief Dieter Zetsche welcomed Mercedes' biggest rivals Audi and BMW to join it on the F1 grid. Noting that the three German brands share some 80 percent of the market for luxury automobiles, Zetsche said that F1 would make a natural arena of competition for Mercedes, Audi and BMW to fight for top bragging rights. The three currently compete against each other in front of home audiences in the DTM touring car series – effectively Germany's equivalent to NASCAR – but of the ten races held this year, the majority were in Germany itself, and all of them took place in Europe. BMW last competed in F1 when it bought the Sauber team in 2006, but withdrew from the series in 2009. Despite its progenitor Auto Union having fielded the famous Silver Arrows in pre-war grand prix racing, Audi has never been a player in modern F1 racing, though recent rumors have linked it to a potential foray – spurred by the arrival of sister-company Porsche on its home turf at Le Mans, the departure of several of its key endurance drivers and the hiring of former Scuderia Ferrari chief Stefano Domenicali. Porsche had similarly considered an F1 program before getting the go-ahead to compete with Audi at Le Mans. As for the prospect of Mercedes competing in other international racing series, Zetsche added that year-long preparations for 24 hours of racing at Le Mans didn't present a good cost-benefit ratio in his estimation, but that Formula E (where Audi currently supports a quasi-works entry) would be worth a closer look.

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.
