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 M4 Convertible poised for Goodwood unveil

It shouldn't be a shock that BMW is working on a convertible version of the M4. Not only have we caught it testing twice, but this is an automaker that seems willing to build a vehicle for nearly every buyer's needs. Evo claims that the high-performance droptop is going to debut at this year's Goodwood Festival of Speed in England from June 26-29.
Judging from the spy shots we've seen, the M4 Convertible will consist of a retractable hard top like the 4 Series cabrio. Other than the roof, there aren't expected to be many changes from the coupe. The engine will be the same turbocharged, 3.0-liter inline six-cylinder engine, but the added weight of the roof and its mechanism may take a small bite out of performance.
We spoke to BMW USA about the rumor and were told that it has no comment at this time. After the M4 Convertible, Evo claims that BMW is working on a M4 Gran Coupe. How that would be all that different from an M3, isn't exactly clear.

BMW X5 gets full battery of performance visuals

If you think BMW toned down its third-generation X5 CUV a little too much with its latest redesign, the new M Performance Parts line of optional parts may give you a chance to inject in a new sense of style.
The aesthetic parts include new carbon fiber pieces for the mirror caps, front splitter, rear diffuser and rear aero flaps. There's also a rear spoiler, high-gloss black kidney grilles, M Performance rocker panel decals and double-spoke 21-inch wheels with performance tires. The interior upgrades are similar with an available Alcantara steering wheel with carbon fiber trim, stainless steel pedals and carbon fiber gearshift trim.
Not all of the M Performance Parts are about style. The M Performance Power Kit sharpens throttle response and boosts power of the X5 xDrive35i to 320 horsepower and 332 pound-feet of torque, an improvement of 20 hp and 32 lb-ft, and an optional exhaust with chrome tips improves its sound. For buyers looking for improved stopping power, the M Performance Brake Kit adds six-piston calipers with 19-inch steel rotors.
