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.

Despite premium carmakers going downmarket, luxury auto sales stick at 10-11%

According to research conducted by global information company IHS Automotive, the leporine birthing of new models by luxury manufacturers over the past six years hasn't increased their market share in the US. Even as car sales reached 15.6 million units, IHS says what's happened instead is that luxury buyers are merely moving from one brand to another, moving from larger luxury vehicles into hot segments like compact luxury crossovers or leaving the market at the same rate as other buyers enter.
Whether broken out by makes or by segment, market share has rollercoastered inside a narrow band from 10.5 to 11.5 percent since "at least" 2008. Closer investigation reveals the shifting boundaries in the aspirational pond, with brands like Mercedes-Benz and Audi gaining territory as Lexus and Lincoln lost it, and Saab and Hummer were buried, dead, under it. One neat note is that Tesla has gone from a share of zip to .12 percent.
The subcompact and compact crossover segments show growth, with those little high-riders jumping from .3 percent to 1.16 percent of overall industry sales. Their rise, though, is concomitant with the decline of four other segments: compact and midsize cars and fullsize cars and SUVs. We think the next few years that will tell if the small-car expansion can overcome the large-car retraction, with a phalanx of smaller offerings like the CLA only recently hitting the market and others like the GLA, Macan and Q1 doing so in the near future.

300-HP 2013 Audi S3 Sportback unwrapped

Not content to let Volkswagen have all of the fun with its GTI and Golf R, Audi is rebooting its five-door S3 Sportback with rather monstrous power. Headed for an official unveil at this year's Geneva Motor Show, the new S3 rolls out with a 300-horsepower, 280-pound-feet of torque turbocharged 2.0-liter TFSI engine under the hood. The four-cylinder powerplant is strong enough to shove the Sportback to 62 miles per hour in just 5.0 seconds when connected to the optional S-Tronic gearbox, or 5.5 seconds with the traditional manual transmission. Top speed is said to be an electronically governed 155 mph. Almost as impressive as those performance figures are the fuel economy ratings: the S- S3 is said to average 34 miles per gallon.
All S3 Sportback models offer Quattro all-wheel drive, ride on a sport-tuned suspension tuned to a lower ride height (about one inch) versus the standard Audi A3. 18-inch wheels with 225-section tires are standard equipment, and 13.39-inch front brakes should offer serious stopping ability.
Audi has done a lot of work shedding pounds from this latest MQB-architecture S3, as well. The car has a curb weight of roughly 3,186 pounds, or some 154 pounds less than the outgoing model. 11 of those pounds were cut via weight-saving measures in the 2.0-liter engine.
