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 Q7 E-Tron Quattro TDI Quick Spin

The operating word is quiet. This refers both to the sound inside the cabin of the upcoming Audi Q7 E-Tron Quattro TDI – even with the diesel engine running – and the company's public statements about its plan for this powertrain in the United States. Basically, while Europe is getting the diesel plug-in sometime next spring (a bit of a delay), all we know for sure right now is that the US will be getting the Q7 E-Tron, probably in 2018, and it will have either a 3.0-liter turbodiesel or 2.0-liter turbocharged gas engine. You may now place your bets as to which one you think the public (or, more likely, CARB) will go for. We're guessing 2.0T. Despite not knowing if we'll ever see this E-Tron TDI on our side of the Atlantic, we recently spent an enjoyable morning tooling around the hills outside Madrid, Spain. As we said, this beast is seriously quiet, and impressively so. Driving Notes The Q7 is a big vehicle, but with powertrain that combines electric motors and diesel thrust, there's a ton of low-end torque. The official 0-62 time is 6.0 seconds, which is basically the same as the 6.1 seconds of the non-PHEV Q7. The Q7 E-Tron is about 500 pounds heavier than the already-4,700-pound Q7, but because of its trick powertrain, never felt sluggish in the hills of Spain. This Q7 E-Tron is a parallel hybrid, with the 3.0-liter TDI diesel engine and the 94-kW disc motor both able to drive the wheels. Overall, they provide 373 horsepower and 516 pound-feet of torque. Despite the parallel system, the not-quite-powerful-enough electric motor doesn't provide the complete electric drive experience that EV fans might be looking for. For example, the Q7 E-Tron has a top speed of 139.8 mph, but that's only in hybrid mode. In EV mode, its top speed is just 78 mph. Audi's Virtual Cockpit display, first seen in the TT, remains an ideal way to give you a wealth of information in an easy-to-see format. It's just as slick in the Q7, where you can toggle the size of the gauges and then pick what you want the screen to focus on, whether that's speed limits, infotainment information, powertrain usage, speed, or navigation.

VW Group recalls 27k Touaregs, Audis and Porsches for fuel leak

The Volkswagen Group is one of the most expansive in the entire industry, and shares parts across more product lines than we could wrap our heads around. So when the German megalith finds a fault in one of its components, it has the capacity to spread like wildfire. The latest set of recall notices from the National Highway Traffic Safety Administration covers vehicles from the Volkswagen, Audi and Porsche divisions. The problem revolves around the fuel injection system, which could potentially leak and cause a fire. The recall affects – deep breath now – the 2012 VW Touareg Hybrid, the 2011-12 Porsche Cayenne S Hybrid and Panamera S Hybrid, 2011-12 Audi S4, S5 and Q7 and the 2012-13 Audi A7. All told, that amounts to 27,376 units, the owners of which can expect to hear from the manufacturer to have the fuel rails replaced, along with their corresponding seals (having nothing to do with marine mammals writing letters).
