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 celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?

Audi A3 E-Tron launching at $51,500 in Germany

Audi has put a price tag on the A3 Sportback E-Tron plug-in hybrid, for which presales begin this month in Germany. To get your hands on one of these little guys, Audi is asking for ˆ37,900, or about $51,537 according to current exchange rates. Of course, the base MSRP doesn't include any incentives, but in Germany, those savings would come from certain annual tax exemptions that apply to PHEVs. Buyers in other countries might have more luck in getting into an A3 E-Tron for less. Audi lists its most important markets for the A3 E-Tron as Germany, Sweden, Norway, Holland, the UK and, despite no firm date for the car's arrival here, the United States. These countries, according to Audi, are where buyers are willing to spend their green (or the more colorful banknotes of Europe) on green cars. These places also enjoy nice things, or in Audi's words, "They appreciate the classic strengths of the Audi brand: high-end technology, uncompromising workmanship, sportiness and elegant design." In Germany, Audi will sell the A3 Sportback E-Tron at select dealerships. The service departments of those 100 or so dealers will get special training to work with the high-voltage technology used by the plug-in hybrid. These locations will also feature free-to-use charging stations for customers. The Audi A3 Sportback E-Tron's lithium-ion battery stores 8.8 kWh of juice, and is supplemented by a four-cylinder, 1.4-liter TFSI engine which works parallel to the electric motor. Total output is 204 horsepower and 258 pound-feet of torque, directed to the front wheels via a six-speed S Tronic transmission. The car can reach 60 miles per hour in 7.6 seconds and has a top speed of 138 mph. It can travel of to 31 miles on battery power alone. Deliveries for the 2015 Audi A3 Sportback E-Tron will begin in Germany and Central Europe this winter.
