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.

Next-gen Audi Q7 shows off its wares ahead of Detroit

Audi has put the Q7 on a massive diet, trimming over 700 pounds. Meet what is sure to be one of the bigger debuts at the upcoming 2015 Detroit Auto Show. The next-generation Audi Q7 has been the subject of spy shots and conjecture for quite some time. After all, it was easily the oldest vehicle in the Audi range, having hit the market way back in 2006. But with this new model, Audi has comprehensively updated its fullsizer, adding some cutting-edge tech, updating some classic engines, and taking a whole lot out. As is the theme nowadays, particularly among large crossovers and SUVs, Audi has put the Q7 on a massive diet with a mix of ultra-high-strength, hot-shaped steel and aluminum, trimming over 700 pounds of body fat and lowering the Q7's weight to just under 4,400 pounds. This was accomplished while maintaining virtually identical dimensions to the current model. While Audi USA hasn't released its info on the Q7, the Euro-spec model will continue to offer a pair of engines that should be very familiar to US consumers, with a 3.0-liter, supercharged V6 gas engine and a 3.0-liter TDI V6. The European engines, though, have had their CO2 emissions halved, while actually increasing performance (we should expect similar from the US engines). The 3.0-liter TDI has been bumped up from 240 horsepower to 272 ponies, while torque is up from 406 pound-feet to 443. The 3.0-liter TDI has been bumped up from 240 horsepower to 272 ponies, while torque is up from 406 pound-feet to 443. This extra grunt has trimmed the 0-60 time from a leisurely 7.3 seconds down to 6.3, while the fuel economy has jumped up to 41.3 US miles per gallon, converted from the European cycle (so expect the EPA numbers to be a bit lower). The supercharged 3.0-liter, meanwhile, has been amped up to match the output of its application in the S4 sport sedan, jumping from 280 hp and 295 lb-ft to 333 ponies and 325 lb-ft. Once again, the 0-60 time falls dramatically thanks to the power bump and weight loss, dropping from 7.7 seconds to a far more zippy 6.1. The most exciting news is the long-rumored arrival of the Q7 E-Tron, a plug-in hybrid that's mated to a six-cylinder diesel engine and Quattro all-wheel drive. Audi claims this world-first production powertrain will return 138.4 US miles per gallon, emit less than 50 grams of CO2 per kilometer and allow the Q7 E-Tron to travel up to 35 miles on electric power alone.

Audi RS6 Avant and Mercedes-AMG E63 S drag race for Top Gear

Sometimes the kids are late for school, and you need a wagon to get them there in a hurry. In its latest drag race, Top Gear finds out which is the quicker high-performance family hauler: the Audi RS6 Avant or the Mercedes-AMG E63 S. The specs suggest this race should be quite close at the finish line. The RS6 has a 4.0-liter twin-turbo V8 with 552 horsepower, but the E63 S is a little more powerful with 577 hp from a 5.5-liter twin-turbo V8. However, the Audi has a traction advantage from the all-wheel drive system, whereas the Mercedes only spins its rear wheels. Pick your favorite, and then watch the video to see if the similar numbers translate to a photo finish in the real world. Related Video:
