2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.

2016 BMW X5 M is big and bold, not beautiful

Awesome as it is, the BMW X5 M has never really been an attractive machine. Big and bulgy are the themes here, and that's only more pronounced with the X5's most recent refresh. But no matter, the X5 M has never been about looks - for this machine, it's all about performance, and BMW's hi-po crossover absolutely delivers in this regard.
Under the hood is the familiar 4.4-liter, twin-turbo V8, though power has been boosted to 567 horsepower and 553 pound-feet of torque - healthy increases of 12 and 53, respectively, compared to the outgoing model. Hitting 60 miles per hour is said to take just four seconds, which is damn impressive considering this thing weighs well over 5,000 pounds.
But the X5 M has always been shockingly good to drive, with limits you'll never reach except in the most hardcore track scenarios (which we'd really like to see, by the way). It's not the prettiest thing ever, but that's okay. It's not exactly cheap, though, with prices starting at $99,650. Woof.

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.
