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.

Updated Audi R8 GT caught testing

When Audi introduced the refreshed 2014 R8, one of the first things we noticed was that the new R8 V10 Plus offers identical output to the outgoing R8 GT, suggesting that this limited-production model was either due to be cancelled or poised for a serious power increase. Fortunately, these spy shots have us suspecting that the latter is more likely.
Like the previous R8 GT, this new model will likely hit the gym, dropping some weight and packing more punch, but while that's all speculative, we do see that better handling is definitely in the cards. Aside from the aero-improving chin spoiler, fascia winglets and fixed rear wing, this R8 also has upgraded brakes with bigger calipers and what appear to be cross-drilled ceramic rotors. We hear output could be increased from the current 560 horsepower up closer to the 600-hp range, and laid to the pavement via Audi's Quattro all-wheel-drive system. It also very likely that Audi will keep production numbers for a 2014 R8 GT rather low, with the outgoing model limited to just 333 units globally.

Five reasons to love, or hate, the culture of German cars

A few months back, we took a 500-foot view of the culture of American cars, dissecting prides and prejudices on our way to the conclusion that automotive allegiances can be simultaneously embraced and derided. We had so much fun with the narrative that we decided to do it again, this time taking a look at Germany and its world-renowned lineup of automakers, including the likes of Audi, BMW, Mercedes-Benz, Porsche and Volkswagen, among others. Join us below as we discuss the points and counterpoints that make or have made the German auto industry what it is today. And remember, Germany did pretty much invent the automobile, after all... The V12 Engine If America is known for the proliferation of the V8 engine, an argument could be made that Germany owns the V12. Yes, of course, other companies have created V12 engines – Ferrari, Jaguar and Lamborghini immediately come to mind – but the big 12-cylinder powerplants from BMW and Mercedes-Benz, in particular, have proven to be some of the most effortless, luxurious and downright over-built engines the world has ever seen. These days, having 12 cylinders is more a case of wretched excess than ever before, and yet, you can still stroll into your local BMW or Mercedes dealership and get a brand-new 760i, S600 or even an over-the-top G65 AMG, efficiency be damned. Best of all, since the majority of these German powerhouses depreciate as fast as an anchor sinks, nearly any auto enthusiast who dreams of a dozen cylinders can satisfy their carnal desires.

If your compression-ignition fantasies err more on the side of fuel savings, that's no problem, either. Audi, BMW, Mercedes and Volkswagen have got you covered, with engines starting as small as 800 cubic centimeters (Smart Fortwo). If you want something a little more practical, it's hard to argue with a VW Golf TDI, which will provide plenty of space for you and three of your best friends, plus a fair bit of luggage, all while returning 50-ish miles per gallon. For the purposes of this discussion, we'd rather focus on the asinine levels of torque provided by Germany's high-end diesel engines than the lower-end fuel sippers.
