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.

2014 BMW 328d ready to burn oil in just four cylinders

Despite showing off the new 328d sedan in New Jersey yesterday, BMW though it only fair to bring the first four-cylinder diesel it will ever sell in the US to the New York Auto Show today as well. Unfortunately, the company remains vague about pertinent details like fuel economy and price, but we did hear again that the oil-burner will be capable of getting 45 miles per gallon on the highway. BMW's Oliver Ganser told AutoblogGreen, "We do not want to give out" the city or combined mpg ratings quite yet, but The New York Times got someone to estimate a fuel economy of mid-30s in the city.
The two-liter TwinPower turbocharged and direct injected engine and eight-speed automatic transmission (sorry, no manual will be available) put out 180 horsepower and 280 pound-feet of torque and should get the 328d up to 60 miles per hour in just over seven seconds. As we noted earlier, the 328d will be available with every option and trim level - like all-wheel drive - that other 3 Series models have in the US (transmission excepted) and should start at under $40,000 when it goes on sale this fall.
Officially, the 328b will be able to accept biodiesel blends up to B5 (or, just maybe B7), which is standard diesel with five (seven) percent biofuel. Read more about that and other aspects of the 328d here.

Vorsteiner BMW M4 GTRS4 shows how to do a widebody at SEMA

Part of the joy of the SEMA Show is that all of the best tuners in the world are competing to show off their wares, and the challenge often pushes the companies into some absolutely insane directions. Case in point: Vorsteiner and its ludicrous GTRS4 wide body kit with the BMW M4.
According to Auto Evolution, the kit reportedly adds 4 inches in the front to fit 10.5-inch-wide wheels and a massive 7-inches more in the rear to snug in 13.5-inch-wide wheels, but spinning around the BMW in these images makes the changes look even more extreme. Beyond just the extra room in the fenders, the lower air intakes are ready to suck in huge volumes of cool air, and there's a front splitter to keep things planted. The front and rear extensions are joined by side sills that grow the farther back they go. Finally, at the rear, the M4 gets a reworked diffuser with mesh inserts.
This is just the type of automotive craziness that makes SEMA interesting. Take a lot at it for yourself in the gallery.
