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.

BMW says SUVs killed the sports car market

In many ways, we're living in a golden age of automotive performance. After all, it's possible to show up at a Dodge dealer, hand over about $60,000 and storm away with a 707-horsepower Challenger Hellcat. Or for those who prefer a touch more luxury, the BMW M4, Mercedes-AMG C63 and latest Cadillac ATS-V offer between 425 and 503 horsepower, depending on your pick, with a bit more poshness. However, none of these powerful vehicles fit the classic definition of a two-place, droptop sports car, and according BMW head of sales Ian Robertson, that's because the segment is very much in the doldrums.
According to Robertson, two factors seriously wounded the classic sports car market. First, the global economic crisis of a few years ago put a serious hurt on sales, according to Bloomberg. Further worsening the situation, the boom in popularity of luxury SUVs and crossovers in the past few years hasn't allowed for much recovery. Even car-hungry China hasn't helped much because of the smog in many cities and preference among some of the very rich there to be chauffeured.
Combined, Audi TT, BMW Z4 and Mercedes-Benz SLK sales peaked around 114,000 units a year in 2007, but they are only expected to reach 72,000 annually by the end of the decade. Robertson is pretty pessimistic about the market's comeback too. "Post-2008, it just collapsed. I'm not so sure it'll ever fully recover," he said to Bloomberg.

2014 BMW 4 Series drops its top, priced from $48,750*

BMW will debut its new 2014 4 Series Convertible at the Los Angeles Auto Show in November, and after seeing plenty of spy shots and, most recently, some leaked images, we now have all the official details. To no one's surprise, the 4 Series convertible is, essentially, a topless version of BMW's new-for-2014 4 Series coupe, and will be offered in the United States in the same 428i and 435i guises.
On the base end, that means the 428i Convertible arrives with the company's 2.0-liter turbocharged inline four-cylinder engine, good for 240 horsepower and 255 pound-feet of torque, and available with either rear- or all-wheel drive. BMW says the 428i will sprint to 60 miles per hour in a respectable 6.2 seconds. For folks in need of more thrust, BMW will happily sell you a 435i Convertible, available only with rear-wheel drive, powered by a 3.0-liter, twin-turbocharged inline-six that produces 300 hp and 300 lb-ft of twist. Hitting 60 mph in the 435i will take roughly five and a half seconds with the standard eight-speed auto. Curiously, BMW did not mention anything about a six-speed manual transmission for either model, so looks like this droptop might be an auto-only affair. We've contacted BMW for confirmation, so we'll keep you posted.
Like the 3 Series Convertible it replaces, the 4 Series uses a three-piece folding hardtop configuration, and BMW says that added sound deadening reduces audible wind noise by about two decibels. Folding the automatic roof takes just 20 seconds, and can be done at speeds up to roughly 11 mph. For chilly, top-down driving (something we're big fans of), there are now three-temperature neck warmers for the front seats - just like what Mercedes-Benz offers with its AirScarf system.
