VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.

Upcoming Audi Q8 coupe-like crossover spied in the snow

At the 2017 Detroit Auto Show, Audi debuted the Q8 concept, a thinly veiled version of its upcoming coupe-like crossover that's set to compete with the BMW X6 and Mercedes-Benz GLE-Class Coupe. We now have spy photos that give us our first look at the Q7-based production version, and through the camouflage we can see how telling Audi's Q8 concept really is. All of the major traits from the concept are present on the production model, including that massive, oversized grille and aggressive roofline. In fact, the entire front end appears to carry over from the Q8 concept, just toned down a few notches. The stainless steel accents on the air intakes are gone, and the headlights, though similar in shape, look more traditional than those on the concept. The small cutouts between the grille and the hood look to be gone as well. Around the side, we can see that the concept's sharply angled rear window and sloping roof have are present, mostly unmodified. The Q8's beltline doesn't appear quite as high as the concept's, but the windows look to be the same relative shape. The big creases above the wheel arches have been reduced slightly. Also, although the Q7 and Q8 will share a platform and therefore a wheelbase, the Q8 is slightly shorter overall. The smaller front and rear overhangs, combined with the tight roofline, give it a high-riding hatchback profile, similar to the Porsche Macan. The changes between the concept and production model are most evident around back. The bumper mounted exhaust pipes have been dropped, at least on this version. The upright vents on the outside of the tail lights have also been dropped. The camouflage around the rear is heavy, so it's difficult to to say how much of the body-width tail light carries over, though the light itself seems to shine through in the same shape. No word on when we'll see a production version, but expect to see the Q8 concept around for a few more shows. Look for more details on the engine, including whether or not the plug-in hybrid powertrain carries over from the concept, closer to the full reveal. Related Video:

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.
