Audi reveals new A3 Cabriolet with Quattro, S3 versions to follow

With the Frankfurt International Auto Show coming home to roost this week, German automakers aren't about to miss out on the opportunity to roll out their latest. Audi may be making the biggest splash with the new Sport Quattro concept, but will also use the occasion to introduce its latest compact convertible.
We just brought you the first leaked images of the new Audi A3 Cabriolet the other day, but now Ingolstadt has revealed the full thing. Slotting in below the A5 Cabriolet and replacing the previous A3 Cabriolet as the entry-level convertible in the Audi lineup, the new cabrio joins the A3 family as the fourth bodystyle in the range.
Based more closely on the sedan than the hatchback, the new A3 Cabriolet is a bit bigger than its predecessor in every dimension but height. Rather than go the folding hardtop route, Audi has stuck with its tried-and-tested hydraulic fabric roof mechanism that can open or close in just 18 seconds. But for the first time, Audi is offering the A3 Cabriolet with Quattro all-wheel drive, and - get this - will offer an S3 convertible version as well, complete with 300 horsepower and a 5.4-second 0-62 time.

Audi S3 pitted against BMW M135i in track battle

Audi and BMW have long been enemies on both the road and the track, with their respective M and S/RS lines duking it out to the delight of auto enthusiasts everywhere. In this video from Evo, two of the rivalry's newest combatants take to the track - the Audi S3 and the BMW M135i.
The new Audi S3, which is finally coming to America, throws down with a 2.0-liter, turbocharged four-cylinder. 290 horsepower and 280 pound-feet of torque are deployed to a Quattro all-wheel-drive system via a six-speed, S-Tronic dual-clutch transmission, allowing the five-door Audi to scamper to 60 in under five seconds.
The BMW, which Americans will know as a long-roof version of the new M235i Coupe, comes to the track with 320 ponies and 331 lb-ft of torque. That's a good bit more than the Audi, but the M135i has only two wheels to send its power to, an eight-speed single-clutch automatic (a six-speed manual is available) and a slightly higher curb weight.

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.
