Audi tech counts down red lights today, reduces traffic tomorrow

Audi announced today that in Washington D.C. and Las Vegas, select Audi Q7 and A4 models will be able to take advantage of new vehicle-to-infrastructure technology. The technology was developed with Traffic Technology Services and will allow drivers to see how long it will take for a traffic light to change to green. Compatible traffic lights will send information through servers operated by Traffic Technology Services to properly equipped Audis. This may not sound like an earth-shattering feature at first, unless you're a stoplight drag racer – if Audi has its way, it may shut off the timer at about 10 seconds to prevent such a thing – but the technology opens up the door to much more useful features down the road. Audi's general manager for connected vehicles, Pom Malhotra, suggested that the information could be used with "vehicle navigation, engine start/stop functionality and can even be used to help improve traffic flow." More specifically, navigation could account for traffic light timing to divert drivers to a more efficient and faster route. It could even suggest acceleration and speed to hit signals when they're green, minimizing stops and starts. Then, for engine start and stop features, the car could selectively shut off at long stops but remain on when approaching a light that's about to turn green. Traffic lights could also start adjusting patterns based on how many cars are approaching a light or are stuck at a light, alleviating slow-moving traffic. Vehicle-to-infrastructure communication could lead to roads that waste less time and less energy. While Audi didn't elaborate on this topic, vehicle-to-infrastructure technology could also be useful for future autonomous car technology. For instance, the car wouldn't necessarily have to "see" the actual traffic light. Instead, it could rely on a separate signal from the smart traffic light to know it has to stop or go. Going a step further, the technology could be used to manage traffic so precisely that traffic signals are no longer needed, as some other groups have investigated. And, of course, the aforementioned benefits in navigation technology would help autonomous vehicles make smarter route decisions as well. The feature is currently only available on Audi Q7, A4 and A4 allroads built after June 1, 2016. It's also only available as part of Audi connect PRIME, a subscription-based service that provides various infotainment and streaming features for your Audi. While D.C.

Audi's Q8 Sport concept packs an electric supercharger

Audi's Q8 Sport concept doesn't wear S or RS badges, but it does have impressive performance that would qualify it for one of those monikers. Beneath the tangerine skin, Audi says there is a hybrid V6 displacing 3.0 liters, which isn't particularly interesting, but the forced induction system is. Rather than a conventional turbo or belt-driven supercharger, the V6 uses an electrically-powered supercharger. Audi doesn't provide any details on what kind of compressor it is, but it says the total output of the engine and motor combo is 476 horsepower and 516 lb-ft of torque. This is apparently good for a 4.7-second sprint to 62 mph. This also isn't the first time Audi has implemented an electric supercharger, having used it before on the SQ7 TDI. That orange shell also has updates to show that this Q8 Sport is the fast one. Most of the brushed aluminum trim of the normal Q8 concept has been swapped for gloss black versions. The regular Q8's grille with its chrome vertical bars is also gone in favor of a black honeycomb piece. The fenders have all been stretched by half an inch, and the exhaust tips are now large ovals that protrude from the rear bumper. Audi still hasn't said anything about when a production Q8 will reach the market. However, there's clearly one coming soon, as we've spotted prototypes running around that look similar to the concepts. Related Video:

2017 Audi A4: Allroad vs. sedan: We explain the differences

We're rotating 2017 Audi A4 models through our long-term fleet. First came the sedan, followed by the Allroad. They briefly overlapped in our garage. The Allroad is a slightly lifted 'estate' version of the sedan, but the differences go beyond that. We go into great depth in the video above. As you'll discover, there are small tweaks to the trim and styling, and larger changes involving the cargo space and pricing. Michael Austin and John Beltz Snyder explain it. Still need more info?
