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 recaps the glory days of M3 performance

Next in the BMW series chronicling the M3 come the second-generation E36 and third-generation E46 models. The E36 ran from 1992 to 2000, upping the game over its predecessor with a 3.0-liter inline-six that started out with 286 horsepower in Europe, or 240 hp when it came to the US in 1994. By the time it ended its run in 1999, it had vastly expanded the lineup and ushered in some key BMW firsts. Going beyond the coupe-only E30, the E36 added sedan and convertible bodystyles, and gave us BMW's Vanos variable cam timing system and the six-speed SMG sequential gearbox. The E46 that launched in 2000 would pare down the bodystyles to coupe and convertible yet go further with design and technical changes. The 3.2-liter inline-six shared only three minor components with the previous motor and put out 333 horsepower at 7,900 rpm. It introduced the power dome, fender vent, and inset exhaust tips as design trademarks. The special editions included the Euro-only M3 CSL, and the second-generation homologation special M3 GTR with a 493-hp, 4.0-liter V8, of which just ten were made. Having made the complete transition from racer for the street to comfortable, perfectly balanced sports car, BMW sold even more of the E46 with just two bodystyles than the E36 with three. Check out the video on the E36 above, then enjoy the look back at the E46 below. If you want to catch up on the latest BMW M3 and its M4 siblings, take a look at the video at the very bottom.

BMW i3 qualifies for both green and white HOV stickers in California

BMW buyers tend to have enough cash on hand to be buffered from the concept of "sticker shock," but the term may take on a different meaning when it comes to the German automaker's i3 plug-in vehicle and its classification by California clean-air regulators. The first i3 EVs are set to be sold in May, and some are questioning if the new car will be eligible for the state's white stickers or green High-Occupancy Vehicle lane stickers, both of which allow for solo-occupancy in HOV lanes. California gives out white stickers to some types of battery-electric vehicles, compressed natural gas (CNG) vehicles and hydrogen fuel-cell vehicles, and there's currently no limit on the number that can be given out. The green stickers, which are applied to other battery electrics as well as some plug-in hybrids, are limited (there are currently about 15,000 left) and will likely run out within the next year or two. The i3's status is uncertain because of it has an optional gas-powered range-extender. Jacob Harb, head of electric vehicle operations and strategy for BMW, told AutoblogGreen that it's not all that complicated. The pure electric version of the i3 will get the white sticker, the REx version will get the green sticker. He also said that both will qualify for the $2,500 state incentive in California and the $7,500 federal tax credit available in all 50 states (For what it's worth, Green Car Reports says the REx version will only get $1,500 from California).
