Audi A1 now testing after S1 Geneva debut

Audi showed of its new S1 hot hatch to the public at the Geneva Motor Show last week, but the Four Ringed brand isn't done tweaking the smallest member of its lineup. Here are spy shots of an upcoming refresh of the standard A1.
The camouflaged model on display here appears to be the three-door model. From what we can discern, it seems the A1 is going to look a lot more like the S1 after the revisions. The headlights and taillights are more like the new performance model than the current standard car. Unlike the S model, the facelifted version has a different front bumper with reshaped foglights and a slightly altered design.
A release date for the refresh hasn't been announced yet, but regardless it probably won't be coming here. Audi is already aiming the A3 at young, American buyers. The little A1 just doesn't fit with that strategy.

Audi A3 Cabriolet leaked ahead of Frankfurt

Leaked images of the new Audi A3 Cabriolet have emerged ahead of the compact droptop's debut at next week's Frankfurt Motor Show. Audi has sold a convertible A3 in Europe since 2008, although that car has never made it to the US market. Still, with Audi already bringing an A3 and S3 sedan across the pond, there's hope for this small convertible to arrive here.
The looks of the A3 Cabrio aren't a huge departure from the A3 sedan, besides the obvious deletion of rear doors. We can't tell from the images shown, but considering Audi still hasn't brought a folding hardtop to market, we don't imagine it'll start with an entry level model like the A3. Expect a fast-folding canvas roof, much like the A5 Cabriolet.
From the leaked images, we can see TFSI and Quattro badges on this A3. It seems natural that the Cabrio will sport the same range of four-cylinder engines as the sedan - a 2.0-liter TDI, a 1.4-liter turbo and a 2.0-liter turbo. Of course, we'll have much more on the new A3 Cabrio when it makes its debut in Frankfurt.

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.
