300-HP 2013 Audi S3 Sportback unwrapped

Not content to let Volkswagen have all of the fun with its GTI and Golf R, Audi is rebooting its five-door S3 Sportback with rather monstrous power. Headed for an official unveil at this year's Geneva Motor Show, the new S3 rolls out with a 300-horsepower, 280-pound-feet of torque turbocharged 2.0-liter TFSI engine under the hood. The four-cylinder powerplant is strong enough to shove the Sportback to 62 miles per hour in just 5.0 seconds when connected to the optional S-Tronic gearbox, or 5.5 seconds with the traditional manual transmission. Top speed is said to be an electronically governed 155 mph. Almost as impressive as those performance figures are the fuel economy ratings: the S- S3 is said to average 34 miles per gallon.
All S3 Sportback models offer Quattro all-wheel drive, ride on a sport-tuned suspension tuned to a lower ride height (about one inch) versus the standard Audi A3. 18-inch wheels with 225-section tires are standard equipment, and 13.39-inch front brakes should offer serious stopping ability.
Audi has done a lot of work shedding pounds from this latest MQB-architecture S3, as well. The car has a curb weight of roughly 3,186 pounds, or some 154 pounds less than the outgoing model. 11 of those pounds were cut via weight-saving measures in the 2.0-liter engine.

Audi RS7 prototype is world's sportiest self-driving car [w/video]

Audi may not be the only automaker out there toying with self-driving automobile technology, but it is arguably the fastest of them. A few years back, it raced unleashed a driverless TTS on the Bonneville Salt Flats, then sent it up Pikes Peak and around Thunderhill. But now it's taking things a step further with the vehicle you see here.
This RS7 Sportback has been fitted with steering, brakes, throttle and transmission hooked up to a computer system that combines GPS, high-frequency radio signals and 3D imaging camera to drive the vehicle autonomously not just in slow-paced, stop-and-go traffic, but around the track at the same pace a professional racing driver would push it: full throttle on the straights, full braking before the corner and 1.1-g of cornering force.
As promised, Audi plans to unleash the self-driving RS7 - which it calls "the sportiest piloted driving car in the world" - at Hockenheim next weekend prior to the DTM season finale, where it is anticipated to pull a 2:10 lap time. The next stage will be to set it lose on the Nürburgring Nordschleife, all 154 turns and 13 miles of it, which ought to pose a heck of a challenge to the engineers from Ingolstadt. In the meantime you can scope it out in the high-res image gallery above and the second teaser video 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.
