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.

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.

American motorcycle brands most satisfying, Japanese most reliable, says Consumer Reports

Consumer Reports started tracking motorcycle reliability last year through its regular reader survey, just like the magazine's well-known auto guide. For the 2015 edition, CR now has data on over 12,300 bikes, compared to 4,680 in 2014, and the extra info means it can include more brands, like Suzuki, Triumph and Can-Am, to the list. However, the final results remain largely the same. As with last year, Japanese bikes are the best choice for buyers who prioritize reliability. Yamaha comes out on top yet again and is followed by Suzuki, Kawasaki and Honda. Victory and Harley-Davidson hold the middle of the list, and the European cycles from Triumph, Ducati and BMW sit at the bottom. The major outlier in this regional distinction is the Can-Am Spyder from Canada's Bombardier Recreational Products that comes in dead last in the dependability survey. Still, even the most dependable model is occasionally going to break, and the average repair bill across all brands is $342, according to CR's readers. Kawasakis are the cheapest to keep on the road at a median of $269 for fixes, versus BMW as the most expensive at $455. Through all of the companies, electrical gremlins are the most common issue, causing 24 percent of problems, but faults with the cooling system, pistons or transmission are the smallest concerns at 4 percent each. While Japanese cycles might be the easiest to keep on the road, they aren't the most beloved by riders. In CR's gauge of satisfaction, the Americans reign supreme. Victory owners love their bikes the most with 80 percent reporting that they would buy another. Harley riders are known for having a close bond to the company's models, and the brand comes in second with 72 percent. Finally, Honda rounds out the top three at 70 percent.
