Audi launches traffic light timing system in Las Vegas

Audi announced today that its new Traffic Light Information (TLI) system will go online in Las Vegas this month, making it the first city to activate a vehicle-to-infrastructure (V2I) system on public roads. The system transmits information from traffic lights to servers operated by Audi partner Traffic Technology Services and onto compatible Audis over a 4G LTE connection. This will allow drivers to see how long it will take the red light ahead to change to green. The feature is available on Audi A4, A4 Allroad, and Q7 models built after June 1, 2016, and requires a subscription to Audi's streaming service. Audi points out that setting up a V2I infrastructure opens up the possibility to provide navigation directions that take traffic lights into account. Cars could even coach drivers how fast to go to hit more green lights. In addition, this information could allow engine start-stop systems to shut off sooner when approaching red lights and start up immediately when the light turns green. Information could also flow back to municipalities, giving them a more accurate picture of traffic flow. Washington will soon join Las Vegas in supporting Audi's V2I technology. They're the only two cities confirmed so far, though Audi says it's working to get more on board. Related Video:

Audi to show hydrogen Q6 in Detroit

Audi is allegedly bringing a hydrogen-powered concept to the Motor City next month. The report comes from Autocar, which cites German media in claiming the new concept, tipped to be called the Q6 H-Tron, will ride on the same MLB architecture as the E-Tron Quattro Concept, shown at Frankfurt earlier this year. In fact, it sounds like the Detroit concept will look more or less like the Frankfurt concept, just with low-mounted hydrogen fuel cells instead of battery packs. That said, Audi didn't come right out and tell Autocar that the Q6 H-Tron was coming to Detroit. Instead, a company spokesman told the website that "a concept car with new drive technology" will be shown at next month's show. But this seems like a safe bet. As Audi continues to cope with the fallout of its diesel emissions scandal, shifting focus to an even more alternative fuel source would be a sound strategy, even if it is just a PR move. Whatever Audi ends up showing in Detroit, we'll be live at the show to report on all of it. Look for more in mid January.

Audi spotted testing new S4 at the Nurburgring

Where there's smoke, there's fire. Only in this case, the smoke is the upcoming new Audi A4, and the fire is the S4 spotted undergoing testing in this latest batch of spy shots. Snapped in both sedan and Avant wagon forms while undergoing testing on and around the Nurburgring – where else? – the next-generation Audi S4 will of course be based on the new A4 that's anticipated to debut in Frankfurt this September. That means MLB Evo architecture and styling that takes a page out of the new TT's playbook. But in S4 trim, it'll be altogether more performance oriented. Expect an even more powerful version of the outgoing model's 3.0-liter supercharged V6, pumping out a good 340-350 horsepower to all four of its driven wheels. That power will help it keep pace with the new Mercedes C450 AMG Sport. It won't have to take on the new C63 AMG directly, though, as that'll be the job of the next RS4 that will slot above it. But since that model may never make it to US showrooms, this will stand as the flagship of the new A4 family as far as the American market is concerned. Related Video:
