Audi bringing new TT Roadster to Paris

The TT may be first and foremost a coupe, but in presenting the third-generation model, Audi has toyed with all sorts of body-styles. There's been the prototypical coupe, of course, but also shooting brake and crossover concepts. The one thing it hasn't shown us is the convertible model, but that ends today as Audi takes the wraps off the new TT Roadster and TTS Roadster.
Set to be unveiled at the Paris Motor Show next month, the new TT Roadster naturally follows its fixed-roof counterpart's lead closely, but with the addition of a folding fabric roof mechanism. Made of magnesium, aluminum, steel and plastic, the mechanism weighs 6.6 pounds less than its predecessor's, helping keep the center of gravity lower. It also folds flatter to allow for more luggage space, and can deploy or retract in ten seconds at speeds up to 31 miles per hour. With the roof up it's also quieter, and with a drag coefficient of 0.30, Audi claims it's the slipperiest in the segment.
Of course, Audi's also worked to keep the weight down and rigidity up. As a result, the 0-62 sprint only takes an extra 0.2 seconds, quoted in the TTS Roadster at 4.9 seconds instead of 4.7 in the TTS coupe. Top speed remains pegged at 155 miles per hour. That, of course, is with the top-spec, 310-horsepower 2.0-liter turbo four, but Audi will also offer the less potent 184-hp version as well as a 2.0-liter TDI, mated to either a six-speed manual or six-speed DCT, though specific performance figures for each version were not disclosed in the press release below.

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.

2014 Audi S1 Quattro [w/video]

Audi may only now be fully committing to the US compact car market with a range of A3 models, but it's got far more small car expertise than most Americans realize, and its offerings get even tinier, too. Back in 2010, Audi leapt into the subcompact premium fray - in all markets but the United States, Canada and China - with its A1. The A1 family has sold all right, but not quite as well as was expected, likely due to its price when optioned up. (It also doesn't help that the Volkswagen Polo is a great car on the same architecture and costs much less.)
But Audi seems compelled to make high-buck S trims of everything nowadays, so right on schedule, I've scored seat time in its new S1 Quattro. Under its gumdrop-colored hood is the very popular 2.0-liter TFSI motor. In this trim, it's good for 228 horsepower and 273 pound-feet of torque between 1,600 and 3,000 rpm. That's quite a lot of gumption for this little blaster - enough power for 0-60 in just 5.7 seconds.
My drive was originally supposed happen on a sub-zero frozen lake in Sweden, only Audi forgot to call Mother Nature and ask her to hold off on springtime. It would have turned into a slush drive and then a submarine test had I been told to stick to the original plan, so it was dusty, soggy and gravel-y pavement instead, which turned out to be a better real-world test anyhow. Plus, the car got even cuter when it was filthy.
