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.

Looking back at 84 years of BMW roadsters

Today BMW is a top player in the luxury vehicle market, but it wasn't always so. With origins as an airplane engine builder early in the 20th Century, it broke into the automotive industry when it bought Automobilwerk Eisenach in 1928. That German manufacturer was licensed to build the Austin Seven under the name Dixi DA-1, which could be had in a roadster body style. In 1929, BMW dropped the Dixi name, and by 1936, it was building a car it designed in-house, the 326 sedan. That was followed by the company's first roadster of its own design, the swoopy two-door 327 of 1937.
XCAR picks up there, and gives a history of BMW's iconic roadsters starting with the 327, ending with today's Z4, and covering everything in between - including the beautiful post-war 507 of 1957 and the funky, plastic-bodied 1989 Z1.
The video, which we've included below, is a good history lesson and a great chance to see a bunch of classic BMWs, spanning 84 years, all driven back to back within the safe confines of a racetrack. When you have a spare 20 minutes, go ahead and take some time to watch it.

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.
