Audi A3 E-Tron plug-in hybrid set to whiz into Geneva

The Audi A3 E-tron, which we drove in prototype form last year, is headed to the 2013 Geneva Motor Show next month. The plug-in hybrid will feature a total of 204 horsepower and 258 pound-feet of torque from the combination of a turbocharged 1.4-liter engine and a 75-kW electric motor. That motor itself is positioned between the internal combustion engine and the machine's six-speed dual-clutch transmission. The setup is good enough to scoot the A3 E-tron to 62 miles per hour in 7.6 seconds and crank out a top speed of 138 mph. Perhaps more impressively, the hatch can whir its way to 80 mph on all-electric power with an EV range of 31 miles.
Audi claims the A3 E-tron gives the world a "realistic glimpse into the future of mobility," so it's a bit unclear if the model will see production. We're encouraged by the specificity of Audi's press release (which is full of stats) and the fact that they don't label this vehicle a concept. You can check out the full press release below and judge for yourself.

The 2013 Rolex 24-hour race at Daytona comes down to the last hour [spoilers, w/video]

It took 24 hours to run the race, but it was the last one was stuffed with the high action as four cars were still trying to figure out how to gain victory on the track and in the pits. Along with the obligatory crashes, spins, mechanical issues and retirements had come numerous penalties, a double-digit number of full-course yellows and two hours of fog that turned early Sunday morning into a stretch of parade laps.
The final hour would make up for the morning - drivers who might have been happy just to get on the podium had a shot at victory as the end of the race approached, and that turned into a few gambles that paid off, and at least one that didn't...

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.
