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.

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.

Nine-time Le Mans winner Tom Kristensen to retire

Le Mans icon Tom Kristensen is retiring. The Danish driver, who was an integral part of Audi's absolute dominance at the 24 Hours of Le Mans, captured a record-breaking nine wins at the legendary endurance race, along with six overall victories at the 12 Hours of Sebring in a career that spanned 26 years.
"Over the past couple of months, my thoughts of retiring have been stronger, and therefore, it feels right to inform you today that I am retiring from motor racing," Kristensen told Autosport. "I still feel I am in peak physical form and possess the necessary mental toughness both in and outside of the car: it has been important for me to stop while I am still strong and able to deliver top performances at Audi."
While the World Endurance Championship's season-ending race at Interlagos on November 30 will be Kristensen's last as a driver, it won't be the end of his long-running association with Audi. According to Autosport, TK will take on a new role as an ambassador for the German marque and will work with team's drivers in an unspecified role.
