Introducing the 2017 Audi A4 Allroad, round 3 of our long-term test

It has been all Audi, all the time for the past few months here at Autoblog. The folks at Audi offered us a unique long-term test of the whole A4 line, a chance to see what it's like to live with the car in all its iterations. We first spent time with a Glacier White Premium Plus sedan. Then we stepped up to a Prestige sedan in Moonlight Blue. Now we're driving a Premium Plus A4 Allroad wagon in Gotland Green. We're saving what we presume will be the best for last when we take delivery of an S4. What we got The A4 Allroad shares the same powerplant as the sedans: a 2.0-liter turbocharged inline-four making 252 horsepower and 273 pound-feet of torque, with a seven-speed S-tronic dual clutch automatic. The setup briskly moves the wagon from 0-60 miles per hour in under six seconds. An Allroad starts at $44,000 MSRP for basic Premium trim. This Premium Plus tester starts at $47,000. Add $575 for the metallic Gotland Green paint - a dignified color that drew back-to-back compliments from a carwash guy and a passing postal carrier, and pairs nicely with the Nougat Brown leather interior. The car is equipped with the $3,000 Premium Plus option package, which includes a sweet Bang & Olufsen 3D sound system; heated, auto-dimming, power-folding side mirrors; an alarm system; heated eight-way power front seats with driver memory; LED headlights; and parking assist . The car also carries the Technology package, in which $3,250 gets you navigation, side and rear sensors, and Audi's elegant Virtual Cockpit instrument display. Those two equipment groups include trials of Audi Connect. The Care, Prime, and Plus packages of Connect offer services such as Google Earth mapping and Google voice search, SOS and roadside-assistance calling, dynamic route guidance, and a lot more. The blind-spot monitoring system packaged with this car is particularly nice, as it employs extra-large amber lights and an audible warning. They greatly augment the rather small, teardrop-shaped side mirrors. Finally, the wagon has the $500 Cold Weather package with heated rear seats and heated, multifunction steering wheel with shift paddles. Its high-gloss burl walnut wood inlays cost $350. Throw in the $950 destination charge and you're looking at MSRP of $52,625. What we skipped We didn't go for the $1,450 Warm Weather Package, which would have provided ventilated front sport seats with four-way lumbar support. The car also came without the rear side airbags, a $350 option.

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.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.
