Audi A8 facelift on the way

The coming Audi A8 has already been spotted in camouflage on public roads at earthly elevations, and now our snappers have caught it at elevation in the Alps. The evolution will entail modified head- and taillights, different sculpting for the grille and a new bumper profile said to be more in line with the A6 S Line.
Inside, there might also be adjustments made to input controls like the gesture touchpad and the MMI infotainment system that include behind-the-scenes improvements like new Nvidia Tegra chips, but such revisions are expected to be minor. With the S8 and the TDI just having been launched, don't be surprised if engine outputs also remain the same. The prevailing sneaking suspicion is that we'll see the car unveiled at this year's Frankfurt Motor Show.

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.

VW orders external probe into diesel emission scandal

There are well over 480,000 Volkswagen-made, diesel-powered vehicles currently traveling roads in the United States that do not meet the Environmental Protection Agency's emissions requirements. This, as you can probably imagine, is a very big deal, and has led VW CEO Professor Doctor Martin Winterkorn to release an official statement on the matter. "I personally am deeply sorry that we have broken the trust of our customers and the public," he said. It's important to note that these vehicles run software with a so-called "defeat device" that kicks in when the on-board computer senses that it is being tested for emissions. When the car is operating normally – in other words, when its exhaust isn't being sniffed – the cars do not meet US emissions standards. According to the EPA and the California Air Resources Board, affected cars emit as much as 40 times the allowable level of certain pollutants. "We will cooperate fully with the responsible agencies, with transparency and urgency, to clearly, openly, and completely establish all of the facts of this case," according to Winterkorn, who added, "Volkswagen has ordered an external investigation of this matter." It's not yet known who will carry out this investigation. At present, there are still a number of 2015 Volkswagen models on dealer lots that do not meet emissions requirements. VW has issued a stop sale on vehicles equipped with the 2.0-liter TDI diesel engine. What's more, the German automaker has been barred from selling 2016 model-year vehicles that use this engine, according to The Detroit News. Last year, diesel vehicles made up about 22 percent of all VW sales, which means these restrictions will have a big impact on the brand's sales performance until a remedy is found and the vehicles are approved for sale. Interestingly, the EPA has started a campaign of sorts to test vehicles from other automakers that sell diesel-powered vehicles in the United States to make sure they comply with emissions requirements under all operating circumstances. The EPA says it "will be reviewing [its] compliance protocols and introducing ways in which [it] can effectively test not only for emissions performance but also for the potential presence of defeat devices," according to a statement provided to The Detroit News.
