Audi reveals S3 Cabriolet ahead of Geneva debut

It used to be if you wanted an Audi S3, your choices in bodystyle came down to hatchback or... hatchback. That is, in markets where the model was offered at all. But Audi has been expanding the A3 global family upon which the S3 is based, and it intends to offer the performance-minded derivative as a three-door hatch, five-door hatch, four-door sedan and - with the introduction of the version you see here - a two-door convertible.
Set to be presented in public for the first time at the Geneva Motor Show early next month, the new Audi S3 Cabriolet packs the same 2.0-liter turbo four as its fixed-roof counterparts - all 290 horsepower and 280 pound-feet of it - but ditches the extra doors and the tin top in favor of the two-door cabriolet bodystyle of the A3 Cabriolet.
The added weight of the folding fabric roof mechanism and the extra body reinforcement required means that the S3 cabrio takes half a second more to reach 62 miles per hour from a standstill than it would take the sedan version, clocking the run at 5.4 seconds instead of 4.9. This, despite more generous use of magnesium, aluminum and high-strength steel in its construction. Top speed, as is the German custom, remains pinned at 155 mph.

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.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models.
