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.

Delphi thrilled with results from autonomous car's cross-country trip

In the first trip across the United States ever made by an autonomous car, engineers from Delphi Automotive were surprised to learn that, in some cases, their vehicle behaved a lot like a human driver. "The car was scared of tractor trailers," said Jeff Owens, the company's chief technology officer. "The car edged to the left just a little bit when it would pass trucks, and that was an interesting observation." Engineers made hundreds of notes throughout the drive, as the autonomous car covered 3,400 miles through 15 states en route to a showcase near the New York Auto Show. Overall, company officials said the car performed better than anticipated in a variety of road and weather conditions. In the course of the cross-country drive, drivers actually controlled the car only for about 50 miles, and those cases were limited to on-and-off ramps and the occasional construction zone where lanes were not marked or only sporadically marked. The purpose of the trip was to glean information on how the autonomous car worked in a real-world environment. Google and others have tested autonomous cars and autonomous features in select real-world environments before, but Delphi's adventure was the first to trek into a test with such varied challenges over a nine-day trip that began near the Golden Gate Bridge on March 22. There are some things the engineers have already learned, like the fact the camera systems had the occasional blip when the sun-angle was low. And there are some things to still be learned, as they pour over three terrabytes worth of data from cameras, radar and lidar sensors in the weeks ahead. "It's going to take us a couple weeks to digest all this," Owens said. "But we had all the data from tests. It was time to put this on the road." Built into an Audi SQ5, the vehicle was striking, if only for the fact it looked like a normal car. Many other autonomous vehicles have quirky sensors atop the roof or other features that make them stand out as experiments. Delphi arranged this one to look as much like a normal car as possible, right down to stowing an army of computers under cargo mats, so the rear contained as much trunk space as the production model. If a fellow motorist didn't know where to look -- or take the time to notice the person in the driver's seat didn't have their hands on the wheel -- there was no reason to suspect this was anything other than a regular car.

Believing in evolution | 2018 Audi S4 and S5 Second Drive

Sales figures for cars in America have plummeted. In a robust overall market, where vehicle purchases have reached record-setting levels, car sales fell by an incredible 9 percent last year alone. SUVs and crossovers are drinking their milkshake, now accounting for nearly two in every three purchases, a profound shift from cars' majority dominance as recently as 2012. Audi's all-new A4 sedan was a bright spot in the brand's car portfolio in 2016, increasing by 16 percent, but A6 and A8 sales fell 18 and 17 percent respectively, and the A5 coupe's sales tanked by a shocking 35 percent. Mitsubishi sold more than three times as many Outlanders last year as Audi did A5s. Were you even aware that Mitsubishi still sold vehicles in America? This trend is expected to continue, perhaps even escalate. But Audi refuses to give up on sedans and coupes. Credit the Teutonic monomania that requires a tit-for-tat escalation and diversification into every existing and invented market segment in which its rivals from BMW and Mercedes compete or don't. (An eminently sales-resistant five-door hatchback, the A5 Sportback, joins Audi's US car lineup in a couple months.) Whatever the instigation, we appreciate it. Cars are an intrinsically more efficient, and more fun, way to move people and goods around compared to SUVs. And Audi's new S4 sedan and S5 coupe prove that we live in a golden age of cars, especially enthusiast cars. At first glance, you might not notice much of a difference between the outgoing cars and these all-new models. Part of this is because the design is extremely evolutionary – though when you start with a pair of models that so elegantly nailed their respective categories, it makes sense not to smash the mold. Closer examination will reveal additional facets, creases, and muscularity in the revised designs. It will also reveal greater differentiation between the related pair, especially around the headlamps, grille, and hood, all of which are meant to be more sporting and exclusive on the two-door, a play to fit with its more sporting and exclusive nature. You might place your faith in other more magical ideas, but we're believers in evolution. The interiors of the cars are similarly evolutionary, and also far more similar. This is not a bad thing. Audi continues to excel in cockpit innovation. We credit it with reinventing the dashboard with the amorphously shaped LCD-screened Virtual Cockpit.
