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 A3 E-Tron goes carbon neutral with German green electricity deal

Audi is proving that the fresh water flowing through the European Alps isn't just for bottling and drinking anymore. The German automaker struck a deal with Hamburg-based LichtBlick to offer buyers of the Audi A3 Sportback E-Tron a chance to get their electrical juice from all renewable-energy sources. That means all the power going into charging stations can come from hydroelectric power from Germany, Austria and Switzerland. The nuts and bolts part of it is that users pay the equivalent of about $12.30 a month plus 37 cents per kilowatt hour for the service. And LichtBlick is indeed legit, as it has been certified by TUV Nord for having at least one third of its power come from hydroelectric plants that are were built less than six years ago. Audi is looking to boost sales from a model it unveiled at last year's Geneva Motor Show. The car pairs a turbocharged 1.4-liter four-cylinder engine with an electric motor that combines for 250 horsepower. Most importantly, the A3 E-Tron gets a combined fuel economy rating of 157 miles per gallon. And while that figure comes from the more generous European driving cycle, it's impressive nevertheless. Check out Audi's press release below and read the Autoblog Quick Spin here. Audi and LichtBlick offer green electricity CO2-neutral mobility with Audi energy TUV-certified green electricity from the energy provider LichtBlick As an accompaniment to the market launch of the A3 e tron*, Audi is offering customers in Germany green electricity – Audi energy. The cooperating partner is the Hamburg energy provider LichtBlick SE. With Audi energy, the A3 e tron is totally emission-free when operated electrically. The power all comes from renewable energy sources and is generated exclusively at hydro-electric power stations in Germany, Austria and Switzerland. The Audi A3 e-tron can be recharged when parked at your home with Audi energy. At the same time, the entire household is supplied with eco-friendly electric power. Audi energy is currently available for a basic monthly fee of EUR 8.95 and 26.76 cents per kilowatt-hour. The origin and quality of the green electricity are certified by TUV Nord. The "OK power" seal of quality also confirms the expansion of power generation from renewable sources: at least one-third of the electricity comes from hydro-electric power plants less than six years old. Providers of this green electricity do not make use of federal subsidies pursuant to the German Renewable Energy Act (EEG).

300-HP 2013 Audi S3 Sportback unwrapped

Not content to let Volkswagen have all of the fun with its GTI and Golf R, Audi is rebooting its five-door S3 Sportback with rather monstrous power. Headed for an official unveil at this year's Geneva Motor Show, the new S3 rolls out with a 300-horsepower, 280-pound-feet of torque turbocharged 2.0-liter TFSI engine under the hood. The four-cylinder powerplant is strong enough to shove the Sportback to 62 miles per hour in just 5.0 seconds when connected to the optional S-Tronic gearbox, or 5.5 seconds with the traditional manual transmission. Top speed is said to be an electronically governed 155 mph. Almost as impressive as those performance figures are the fuel economy ratings: the S- S3 is said to average 34 miles per gallon.
All S3 Sportback models offer Quattro all-wheel drive, ride on a sport-tuned suspension tuned to a lower ride height (about one inch) versus the standard Audi A3. 18-inch wheels with 225-section tires are standard equipment, and 13.39-inch front brakes should offer serious stopping ability.
Audi has done a lot of work shedding pounds from this latest MQB-architecture S3, as well. The car has a curb weight of roughly 3,186 pounds, or some 154 pounds less than the outgoing model. 11 of those pounds were cut via weight-saving measures in the 2.0-liter engine.
