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.

Evo pits BMW M3 against Porsche Macan in drag battle

If you want to move five passengers in very rapid fashion and you've got a $75,000 budget, two newly introduced four-door models immediately come to mind - both are the highest performing vehicles in their respective segments. But which is faster off the line, to the 60-mile-per-hour benchmark or flat-out over an even longer run? Evo took both to paved aircraft runway to find out.
In lane one we've got the all-new Porsche Macan Turbo, which boasts a twin-turbocharged, 3.6-liter V6 rated at 400 horsepower and 406 pound-feet of torque. The Porsche is fitted with a seven-speed, dual-clutch gearbox, and the 4,244-pound crossover has the traction advantage of standard all-wheel drive. In lane two is the all-new BMW M3, powered by a twin-turbo 3.0-liter inline-six rated at 425 horsepower and 406 pound-feet of torque. It is also equipped with a seven-speed, dual-clutch gearbox, but only the rear wheels of the 3,595-pound sedan are driven. Both the BMW and Porsche arrive with launch control, which helps to remove driver error off the line.
Which automaker's launch control system is better off the line? Does all-wheel-drive grip give the crossover the advantage it needs to overcome its adversary's power-to-weight advantage? Will aerodynamics factor into the results? Which would you put in your garage, and why? The video may surprise you.

BMW M3, M4 let loose on the 'Ring

We just posted our first drive of the 2014 BMW 435i yesterday, but for those wanting even more power from this stylish coupe, help is on the way. From the sounds of it, BMW will be showing off a production-ready concept previewing the M4 next month at the Pebble Beach Concours d'Elegance, but until then, we have some new spy shots of the performance coupe being tested at the Nürburgring, along with its four-door counterpart, the M3.
Despite all the camouflage, it doesn't take much imagination to picture what both cars will look like, since we can clearly see the more aggressive front fascia and beefier brake setup. One interesting element we see on both cars is a double bubble roof that is almost certainly made from carbon fiber. Based on our report earlier, both the M4 Coupe and M3 Sedan are expected to debut at the 2014 Detroit Auto Show.
