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.

2015 BMW M3 Sedan

BMW's all-new M3 Sedan is dynamically nearly identical to its two-door M4 Coupe sibling: a stopwatch reveals that both are sub-four-second cars to 60 miles per hour, a racetrack proves that the mechanical twins are equally as adept on a road course and a full afternoon of driving on public roads demonstrates that each possesses talented everyday adaptability.
Yet after driving both BMW models back-to-back over two full days in Portugal, it's clear there are a few noticeable differences, both objective and subjective, that don't require instrument testing to reveal. All it takes is a few hours behind the wheel of both cars to conclude that one is slightly more agile, and the other a bit more twitchy. One has better outward visibility, while its counterpart is unquestionably more convenient.
It is the little things - subtleties attained through seat-of-the-pants observations - that eventually allow me to choose a favorite.

2015 BMW i8 sets everyone's tongues wagging in Northern Michigan

Like few other cars we can remember, people want to talk about the 2015 BMW i8. Drive one, and you'll soon find out what we mean. They stop you at gas stations. They accost you in Walgreen's parking lots. They stream out of neighborhood bars, beers in hand.
At least, that was our experience this week during Autoblog's Technology of the Year testing. We had the pleasure of driving the plug-in hybrid BMW sports car up to and around Petoskey, MI, a resort town where seeing such exotics is rare enough, let alone in the off season. It made for some interesting conversations - so we began writing down some of the comments the butterfly-doored coupe inspired. Here's a sampling:
"Wanna race for pinks? I'll go easy on you." - Acne-covered teenage pizza delivery driver in a sad-looking Ford Taurus parked at a Valero gas station near Grayling (which incidentally didn't actually have gas).
