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.

Alex Zanardi talks new challenge at 24 Hours of Spa with BMW

"I have overcome greater things in my life than driving at night." When considering Alex Zanardi's tumultuous life and racing career, the notion that he might be worried about racing for the first time at night seems patently absurd the moment I pose the question. But as I've discovered previously, ask Zanardi a question and his reply - even a brief one - will offer analysis. "I'm really looking forward to it," he says, before adding: "Also, it will be much cooler." Zanardi is talking about the latest installment in his racing career - the 24 Hours of Spa - where he will race a BMW Z4 GT3 alongside fellow ex-Formula 1 driver Timo Glock and DTM driver Bruno Spengler. For the second year, Zanardi is running with ROAL Motorsport, and the team has the full weight of BMW behind it as it prepares to go up against 57 other cars on the historic Belgian circuit this weekend. I first met Zanardi last year at Brands Hatch on a hot May afternoon after his one-hour Blancpain Sprint Series race. He was exhausted and downing can after can of cola but still happy to chat to fans as he cooled off. I ask why, if that was such a tough experience, he is prepared to do it for 24 hours. "It's a good question, why would I?" he ponders aloud before quickly adding: "I am confident I am as well-equipped as I can be to face such an enormous commitment." That confidence comes from three developments that have allowed him to be the first disabled driver to race the Spa 24H. Firstly, his athleticism; since Zanardi lost both his legs in the horrific CART accident at the Lausitzring in 2001, he has drawn admiration for his subsequent achievements as a racing driver and paracyclist; the Italian won two golds and a silver at the 2012 London Paralympics in handcycling. The man is seriously fit. The next major change is inside the Z4 cockpit, where he has worked with BMW engineers to adapt the braking system without hindering his able-bodied teammates; having two others sharing the car with him is a new challenge for both Zanardi and BMW. New controls, particularly the brake pedal, were designed with impressive results. "[The engineers] made my life easier quite dramatically via ergonomics, pushing the brake pedal and the footrest where I put my prosthetic feet to the side of the space that was available. "This makes everything better for me. The ratio of the brake pedal is changed.

2015 BMW X4 xDrive28i

When BMW unveiled the X6 back in 2008, critical reviews were mixed, to say the least. By all accounts, the heavyweight crossover actually drove quite well, but the idea of a BMW X5 that traded a lot of functionality for polarizing looks and a higher price tag seemed like a tough sell. Then it went on sale and quickly proved to be a cash cow. Today, the German brand has moved over a quarter million of the things worldwide. Unsurprisingly, this success has moved BMW to double down on its so-called Sport Activity Coupe by adding a smaller variant. The all-new X4, while not a bad steer in and of itself, makes even less sense than its big brother, particularly when viewed alongside BMW's other offerings. Like the X6 and X5, the X4 borrows heavily from another of the brand's utility vehicles, in this case, the less-costly X3. Also like the X6, this new crossover-coupe's styling is sure to cause a schism among critics and consumers alike. You can probably guess where the majority of the Autoblog camp falls. To be totally frank, the exterior of the X4 is simply ghastly to this writer, particularly in this tester's eye-catching paint. Admittedly – and much like the X6 – there's not much objectionable from the A-pillar forward, where the X4 has a lot in common with the X3. It's only once moving towards the rear that things well and truly go wrong. There's just so much visual mass, and it's been made worse by the way BMW designers wussed out. Bear with me. Compare the profile of the X6 with the X4, and pay particular attention to the roofline on the bigger vehicle. The angle of the roofline is noticeably more dramatic on the X6, which comes at the expense of second-row headroom (an oft-criticized area for the big boy). For the X4, designers tried to have their cake and eat it too, maintaining second-row headroom but with a coupe-like profile. The result is an X4 that is bulbous and uncouth from the B-pillar back, more hunchbacked Gran Turismo than svelte Gran Coupe. BMW might have been better served if its exterior work had followed the stylings of the cabin, which is more or less a clone of what's on offer in the X3. Material quality is still great, with soft-touch plastics and available cool-to-the-touch brushed aluminum throughout. I really dug the Ivory White Nevada leather and contrast red stitching on this test vehicle, as it provided an eye-pleasing departure from the sea of blacks, grays and tans so typical of the luxury crossover market.
