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.

2015 BMW Alpina B6 xDrive Gran Coupe priced from $118,225* [w/poll]

If you're in the market for a high-performance BMW and you live in Europe, you've typically had two range of options at your disposal: you could go for one of BMW's own M models, or turn to Alpina. Though technically independent of BMW, Alpina is about as close to the manufacturer as a tuner can get, and many of its models are offered through BMW's own dealer network.
That's overseas, but in the North American market, BMW has typically taken a different approach, offering just one Alpina model - the B7 - to fill in for a lack of M7 performance sedan. That all changes, however, with the debut of the BMW Alpina B6 xDrive Gran Coupe.
Slotting in alongside the M6 Gran Coupe, the Alpina B6 xDrive Gran Coupe is marginally more expensive and slightly less powerful, but makes up for those relative (and negligible) shortcomings in spades. Both are based on the 6 Series Gran Coupe and both pack a 4.4-liter twin-turbo V8, but with key differences. Where the M6 produces 560 horsepower, the Alpina offers 'only' 540. But where the M6 channels 500 pound-feet of torque to the rear wheels through a seven-speed dual-clutch transmission, the Alpina drives 540 lb-ft to all four wheels through an eight-speed automatic.
