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 Concept Roadster has two fewer wheels than we were expecting

The annual Concorso d'Eleganza Villa d'Este on the shores of Lake Como is an opportunity for some of the most beautiful vehicles in the world to descend on one of the poshest places on earth each year. Unsurprisingly, the event is also increasingly the chance for automakers to debut exclusive concepts to some of the wealthiest auto enthusiasts in the world. In the last few years, BMW has become the masters of this annual unveiling with automotive concepts like the Gran Lusso Coupé, BMW Zagato Coupe and motorcycles like the the gorgeous Concept 90, not to mention the just-revealed Mini Superleggera Vision. But this year the Bavarian automaker has been somewhat tricky.
What would you first think when you heard of the BMW Concept Roadster? A lithe, two-seat convertible? Nope. This roadster is a cut-down, minimalist motorcycle with an ultra-modern design. As opposed to the retro looks of the Concept 90, this naked bike looks like it could fit in a BMW showroom tomorrow and not seem out of place.
The Concept Roadster packs the brand's classic two-cylinder boxer engine displacing 1,170 cubic centimeters and producing 123 horsepower and 92 pound-feet of torque. That power is routed to the rear wheel via a cardan drive, essentially a driveshaft, with a single-sided swing arm rear suspension. It's all nestled in a tubular spaceframe.

Recharge Wrap-up: Grimsel electric car breaks acceleration world record, electric Ford Raptor ATV debuts

An all-electric version of the Ford F-150 SVT Raptor is now available... as an ATV. Made by Caddyshack Golf Cars, it features officially licensed Ford badging borrowed from the super-macho pickup. It has a lifted chassis with leaf springs in the front and rear, hydraulic shocks and off-road tires. Powered by a 48-volt motor, it can do 0-25 mph in 2.9 seconds. Range is an estimated 30 miles - plenty to get you through 18 of the most rugged holes of golf you've ever played. Caddyshack also offers other miniature electric Fords, including a Shelby GT500, Shelby Cobra and 50th Anniversary Mustang. Read more at Green Car Reports. Lexus takes a crack at the BMW i3 in a new video from Funny or Die. In the decidedly anti-EV film, a group of guys drives to Las Vegas for a "dad-chelor party" in a Lexus CT 200h and a BMW i3. The Lexus hybrid makes it to Sin City without any problems, while the BMW's occupants need to make several lengthy stops to charge along the way, missing much of the fun. The video lampoons the inherent range limitations of the EV (the BMW group ends up driving slowly through the desert with no AC or radio to save energy), all in a well produced, if somewhat misguided, short comedy film. Perhaps they should have considered the i3 with a range extender? See the video below, or read more at Green Car Reports. Students from ETH Zurich and Lucerne University have set a new EV acceleration world record. Their "Grimsel" racing car was able to zoom from 0-100 kph (0-62.137 mph) in just 1.785 seconds in less than 30 meters (98.425 feet), crushing the previous record of 2.134 seconds. Even more impressive is that the Grimsel was built by the students themselves, as part of the Formula Student team at the Academic Motorsports Club Zurich. The car weighs just 370 pounds and provides 200 horsepower and 1,202 pound feet of torque from the four hub motors. The Grimsel uses traction control to manage torque for maximum acceleration. See the record acceleration run in the videos below or read more at Gizmag, at Electric Autosport or in the press release from ETH Zurich below. 'grimsel' breaks world record The 'grimsel' electric racing car today broke the previous world record for acceleration in electric cars. The vehicle accelerated from 0 to 100 km/h in 1.785 seconds in under 30 metres. The new record was set by students from ETH Zurich and Lucerne University of Applied Sciences and Arts, who also designed and built the vehicle.
