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, MIT, GE start cab ridesharing study in New York City

Audi, Massachusetts Institute of Technology's (MIT) and General Electric are getting together to study something that won't likely be thrilling for New York City cab drivers. But there are bigger fish to fry and keeping cabbies happy. The German automaker is working with MIT's Senseable City Lab and GE on a study designed to get a better handle on how ridesharing in the city's cabs could work and how such a practice could cut both emissions and traffic in the largest US city. The program, dubbed HubCab, will track more than 150 million taxi trips in a year. The broader idea is to figure out how ridesharing could cut trips by 40 percent. That's not likely to please the holders of those coveted NYC taxicab medallions but would certainly benefit the city in other ways. "The aim of HubCab is to spark thinking about ways of utilizing publicly available data as we explore new concepts for mobility, especially in crowded urban contexts," said Audi spokesman Brad Stertz. Stertz allowed that there remained many legal and "customer acceptance" issues to address with ridesharing and that there was no timeframe for concluding the study or when the findings would be put into effect via an actual ridesharing system. At least it's a start. Check out Audi's press release below. MIT, Audi launch HubCab project in New York City • HubCab will track more than 150 million taxi trips in NYC to gain insight on ride share scenarios • Insights will inform researchers on how car sharing systems can lower vehicle emissions, reduce congestion, and save money and time • Scientific study conducted at Massachusetts Institute of Technology's Senseable City Lab with support of VW Group's ERL, Audi and GE MIT, in partnership with Audi and GE, launches HubCab – a transportation tracking tool aimed at reducing commuting congestion, decreasing vehicle emissions and dramatically lowering the cost of mobility infrastructure. HubCab tracks more than 150 million taxi rides in New York City over the course of a year. With this information, researchers can identify commuter travel patterns and work to develop a more efficient car share system. MIT researchers say HubCab technology could not only save people money and time, but allow users to better plan their taxi rides around the city, potentially reducing the number of trips by 40%.

Autoblog's ultimate holiday rides

Over the hills and through the woods, it's the time of year when many of us visit family and friends for the holidays. But getting there can be a chore. It's cold and snowy across much of the United States, and even if the climate is favorable, the drive to grandmother's house often is not. Think back to holiday road trips of yore: They probably included crying babies, antsy children, hungover adults and frequent bathrooms stops all around. Now, we're all at different life stages here at Autoblog, and the perfect car for one staffer might be as useful as a team of Budweiser Clydesdales to another. Some of us bounce from family event to family event with children and a labrador in tow, while others prefer a quieter, simpler holiday. But whatever the endeavor, we all need wheels. With that in mind, here is the unofficial Autoblog list of the ultimate cars in which to tackle the holiday season. 2015 Ferrari FF To borrow a chestnut from Top Gear presenter James May, "As you'd expect, I've done this properly." That oddly voluptuous ruby bolide in the photo above? It's a 2015 Ferrari FF – all 652 all-wheel-driven horsepower of it. What makes a Ferrari the ideal for holiday time in PaukertLand? My Midwestern winter breaks are wonderful, but they're typically frenetic and slushy, involving a lot of schlepping from house to house and even city to city, not to mention inevitable last-minute runs for forgotten presents and dinner ingredients. Needless to say, a powerful V12 is a welcome ally for such duties. And this one isn't just a friend when the road is clear. The FF has been gifted Ferrari's novel 4RM AWD system, and despite sitting lower to the ground than, say, an SUV, it's a pretty effective tool for real winter driving, especially when outfitted with a set of snow tires. Unlike other Ferraris, it's also a rather practical thing, with legitimate seating for four adults and 15.9 cubic feet of cargo space – that's precisely as much room as a Mercedes E-Class – and you can fold the rear chairs and cram 28.2 cubes-worth of holiday cheer in the back. Okay, so it's far from cheap and fuel economy isn't that great, but who cares? Just drop a paddle-shifted gear or two, bury the throttle and Repeat The Sounding Joy.
