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 5 Series wagon makes incognito grocery run by way of the 'Ring

With a debut in 2009, it's high time that BMW delivered the world with the standard mid-cycle refresh of its popular 5 Series. While we aren't expecting to see it here in the United States, that freshening will include the vehicle shown above, the 5 Series wagon.
This is only the second time we've spotted the camo'd, long-roof 5er in the past year, and while it was chained to a flat-bed in those snaps, today, we can see it lapping the Nürburgring. In addition to the images from the track, we also have our first look at the cabin of the freshened 5 Series, although even it is covered in camouflage, making it quite difficult to spot anything of substance.
As for the exterior, expect modest changes for the second-half of the F10 5er's life, with typical tweaks like new headlights and taillights, and perhaps a freshened front fascia. Considering we last saw the upcoming 5 Series just over a year ago, we'd expect an auto show debut for this smoothed-over model in the not-so-distant future, with Paris a leading candidate.

BMW E9 3.0L CSL Batmobile is an awesome retro racer

When BMW released pictures of its 3.0 CSL Hommage earlier this year and then brought a period-livery racing example to Pebble Beach, this is the car it was looking at. The BMW E9 New Six CS came before BMW Motorsport and BMW M cars existed, and well before the tagline "The ultimate driving machine," but it paved the way for all of them. Built as a road-going coupe from 1968 to 1975, 1,265 units out of a total production run of 30,546 units were homologated for the European Touring Car Championship. Fitted with the final specification aero package in 1973 and powered by a 3.003-liter inline six-cylinder with a base rating of 200 horsepower, it proved such an able racer that it won the overall ETCC trophy six times - four of those after its road car donor had ceased production, and a bunch of other races like a class win at Le Mans. Clean samples go for huge money. That aero kit earned it the nickname "Batmobile," and Car Throttle drove a left-hand-drive version in the UK (BMW did build 500 right-hand-drive models, though). This is less a car review and more a dream drive, the host letting us know right off that the 3.0 CSL is the one car he's wanted to drive more than any other. He also finds that the Coupe Sport Leicht had a stop/start system... of the temperamental kind. Check it out in the video above. Related Video:
