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.

Audi SQ7 coming, will have electric turbo

Formula 1 and endurance racing are already harvesting energy from turbos on the track, and now it's apparently time for a similar idea of boosting the efficiency of forced induction to hit the streets in a high-performance, diesel SUV.
In a recent interview with the UK's Autocar, Audi technical boss Dr. Ulrich Hackenberg let the big news slip. "The new Q7 will be available in the market next year but the electric turbo will come a bit later in the Audi SQ7 available in 2016," he said. The e-turbo system was already rumored for the premium SUV but for the standard model, not this just-announced performance version.
Audi has been experimenting with the e-turbo system for a little while, as an electrically driven supercharger. It showed up on the RS5 TDI concept that used a 3.0-liter, twin-turbocharged diesel V6 plus the electric system to diminish turbo lag. In that application, it provided an impressive 385 horsepower and 553 pound-feet of torque and an alleged sprint to 62 miles per hour in 4 seconds. Although, Dr. Hackenberg didn't make it clear if this was the exact layout for the SQ7.

Audi E-Tron Sportback Concept previews 2019 production model

Audi has revealed the E-Tron Sportback concept it has been teasing ahead of Auto Shanghai. The all-electric model, the automaker says, previews a production model slated for 2019. Audi will launch an electric SUV with a driving range of 311 miles in 2018. "Following close on its heels, in 2019," says Audi Chairman Rupert Stadler, "comes the production version of the Audi E-Tron Sportback – an emotional coupe version that is thrillingly identifiable as an electric car at the very first glance." The E-Tron Sportback is powered by three electric motors – one on the front axle, and two on the rear ­– providing a total 320 kW (429 horsepower), with a boost mode that ups that output to 370 kW (496 hp). It's capable of a 0-62 mile per hour sprint of 4.5 seconds. A liquid-cooled 95-kWh lithium-ion battery provides 311 miles of driving range (on the European cycle). The concept features Audi's singleframe grille, with an illuminated four-ring logo. The front of the car is shaped for optimal airflow, and the dip in the hood also gives it a uniquely sporty look. Its front fascia integrates lighting that not only illuminates the road, but can project animations or provide communicative signals to other drivers or pedestrians. Its 23-inch wheels are imposing, giving the car a muscular stance. Side mirrors are replaced by slender cameras, which improve airflow and provide a better view of the car's surroundings, helping to eliminate blind spots. By revealing the E-Tron Sportback concept in China, Audi is acknowledging the significance of the country's electric vehicle market. "There are already about 150,000 charging stations in the country, with another 100,000 due to come on stream by the end of 2017," notes Audi Board Member for Marketing and Sales, Dr. Dietmar Voggenreiter. "We are well equipped for this rapid growth. In the next five years we will be offering five E-Tron models in China, including purely battery-powered vehicles with ranges well in excess of 500 kilometers (310.7 miles) such as the Audi E-Tron Sportback."
