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 gets the video retrospective treatment

With BMW on the cusp of pulling back the sheets on its next-generation M3 (or should we say, M4?), the crew from Electric Federal has taken it upon themselves to give us a generation-by-generation look at the evolution of the most renowned of BMW's sports coupes. The video below features plenty of beautiful shots of each generation of M3, starting with the ever lust-worthy E30 before finishing up with the current iteration. BWS Motorsport's Mark Norris provides the narration, complete with a brief synopsis of what makes each generation so special.
As usual, the clip is fit for big-screen viewing. You can watch the action below for yourself. Meanwhile, we'll be busy figuring out which vital organs we can sell to get our hands on our own E30 M3.

2015 BMW X4 is a budget X6

We won't argue that crossovers are hugely successful vehicles, with automakers working to provide functional CUVs in a wide range of sizes. But over at BMW, things are just getting out of hand, as evidenced by this new X4 "Sports Activity Coupe" that debuts here at the 2014 New York Auto Show.
BMW is seeing fit to offer vehicles in even the most niche of niches, and the X4 is no exception. Want proof? Have a look at the X4, and the compare it to the X3, the 3 Series Gran Turismo, the 3 Series Sport Wagon, and the 4 Series Gran Coupe. Aside from marginal differences in things like ground clearance and the exact slope of the hatchback, what, exactly, is the difference?
Like the other models we just mentioned, the X4 is powered by either a 2.0-liter turbo-four with 240 horsepower or a more powerful, 3.0-liter turbo-six with 300 horsepower, and unsurprisingly, power is sent to the ground exclusively via the company's xDrive all-wheel-drive system. An eight-speed automatic transmission is the sole gearbox available with either engine. All sounds very familiar, right?
