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 M3 and M4 will rock 430 hp from twin-turbo six with standard manual [w/video]

We're not sure which spec we're most intrigued by for the new BMW M3 and M4: the twin-turbo six-cylinder with 430 horsepower and "far beyond" 369 pound-feet of torque, the 3,300-pound curb weight or the standard six-speed manual transmission with automatic throttle blipping on downshifts. That engine is fitted with both Valvetronic and Double-Vanos, twin-wire arc-spray coating in the cylinders instead of liners to save weight, a track-ready cooling system with additional radiators, a forged crankshaft, dry-sump lubrication and a magnesium oil sump. BMW says its "high revving concept" has a redline beyond 7,500 rpm.
In the M4, it will be pulling a coupe with "a weight of just under 1,500 kilograms," which is 3,300 pounds to you and me. That number is said to include no driver and 90 percent fuel, but we're still waiting on the exact number and specs. BMW says it's "around 80 kilograms lighter than a comparably equipped predecessor model," putting the power-to-weight ratio at something like 7.68 pounds per horsepower at the same time as it helps reduce fuel consumption by 25 percent. The use of carbon fiber reinforced plastics (CFRP) for the roof, drive shaft (with no center bearing), trunk and front strut brace, and forged aluminum for suspension components, have aided in the weight loss. This time around, the sedan - the M3 - will also get a CFRP roof.
The default option will be a six-speed manual.

Cafe racer motorbikes storm Japan

Japan may be best known, at least among motorcycle enthusiasts, for its sport bikes. But as we found at the Tokyo Motor Show this year, Japanese motorcycle manufacturers are capable of producing all kinds of motorbikes. And to our delight, that includes cafe racers.
Along with the myriad electric bikes, dirt bikes, crotch rockets and scooters, the halls of Tokyo's Big Site convention center this year were full of the retro-infused rides we love. Chief among them was the Bolt (shown above) which Yamaha exhibited alongside their various electric two-wheelers, sporting a delicious metallic blue paintjob, inverted handlebars and hanging mirrors, machined metal bits, blacked-out trim and saddle brown leatherwork.
Honda was also on hand with a new EX version of its '70s-style CB1100 retro roadster in sinister and low-key matte black. And this was our first chance to check out BMW Motorrad's new birthday present to its 90-year-old self, the R NineT, a model recently unveiled at the EICMA motorcycle show in Milan. But one of the most amusing retro rides we came across was the Honda Monkey Limited, a mini bike that makes the new 125cc Grom (which was displayed alongside it) look positively gigantic.
