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 M235i in circuit scrap with legendary E46 M3 CSL

Earlier this month, we brought you news that BMW's one-year wonder, the 2011 1 Series M Coupe, is actually trading for more money today than it did when new. That sort of short-term appreciation is a major rarity with modern production cars, but apparently it's not the only BMW enthusiast coupe to enjoy far-above-average residual values. The not-for-North America 2004 M3 CSL, itself a single-year offering, apparently also fits that description, as we've just learned from Auto Express.
The M3 CSL ruled overseas BMW showrooms a decade ago, with just 1,400 examples built. Based on the well-regarded E46 M3, the rare two-door was relieved of extraneous bits for improved track work and driver fidelity, coming in at around 240 fewer pounds than a garden-variety M3. With carbon-fiber-reinforced plastic bodywork, thinner glass and a lot less sound insulation, the CSL was one of the more raucous cars of its day. Like the 1M Coupe, it was also one of the more connected cars of the era, with a retuned suspension, quicker steering, and a bit more power than its brethren.
As Auto Express points out, a good used one commands about the same money as a brand-new 2014 M235i - the closest thing BMW makes to a 1M Coupe today - which makes this video track battle an interesting new-versus-used showdown. According to AE, a well-sorted used M3 CSL will run UK consumers anywhere between £30,000 and £35,000 - roughly $50,000 to $59,000 US. That's a massive premium over the $10k-17k British buyers can expect to shell out for a comparable standard M3, similar to the story that plays out for the 1M versus lesser 1 Series variants.

BMW expounds on i8 design and performance in new videos

At this point, there isn't much we don't know about the 2015 BMW i8, so BMW is starting to focus its attention on reassuring consumers that the future of BMW won't abandon the past. In these two recently released videos, BMW answers questions prospective buyers might have about about the new model's design and performance.
In the design video, BMW explains how the i8's styling is intended to be practical, with aerodynamics and fuel efficiency in mind, yet still have a sporty and dynamic look. The performance video aims to show that the plug-in hybrid can be fuel efficient while still delivering plenty of performance, and it shows an animation about how the i8's drive systems work together. Scroll down to watch both videos on this bold green supercar.
