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.

As BMW i3 US launch nears, more details discovered

Think of the BMW i3's gas-powered range-extender as akin to driving around with a middle linebacker in the back seat. Except that football player will have a hard time pushing the car 60 miles or so once the battery runs out. Thankfully, he won't prevent you from getting a nifty tax credit either, according to BMWBlog, which isn't affiliated with the company. The i3's front storage compartment is not watertight. Here in the US, where the i3 will be available in short order, BMW will offer an optional i3 plug-in vehicle with a range extender that will have a 1.9-gallon capacity gas tank. That sounds a good deal smaller than the 2.4-gallon tank used in Europe, but the two are actually the same, the US tank is simply limited to the smaller size, Dave Buchko, from BMW's product and technology communications department, told AutoblogGreen. The complete range extender system – including the tank, the engine, and all related hardware – adds about 265 pounds to the 2,634-pound curb weight of the i3 EV and the extra weight in turn adds about a second to the EV's 0-to-60 time of seven seconds flat. Adding the range-extender won't make the US government take any longer to dole out a $7,500 tax credit for the i3, though. We also learned that the i3's front storage compartment is not watertight since it is only meant to hold the mobility kit and the 110-volt charging cord. BMW recently increased its production of the i3 at its German factory from around 70 units a day to about 100 due to better-than-expected demand.

2014 BMW 4 Series Convertible [w/video]

Here it is, the fifth generation of BMW's 3 Series Convertible - only this one begins with a "4," having been rechristened as a droptop version of the new 4 Series Coupe. With thirty years of work on this same recipe and having gotten it so right for much of that time, the Munich compact premium convertible has been a WYSIWYG affair for decades: once you saw its sedan paradigm, you knew what it was going to look like in roofless two-door form, and what you saw is exactly what you got.
It is ridiculous to think that BMW would choose this new model and its new nomenclature to muck things up. The new car has, though, gotten larger and roomier, and even though it's now part of the racier coupe division within the company's compact line, it has gotten more, shall we say, mature. Driving even further away from the days when handsomely tipped bartenders could work their way into one, The Ultimate Tanning Machine had shed even more elan, going instead for elegance and an attitude befitting its $49,675 starting price (including $925 for destination).
It strikes a few odd notes, but what it does best, it still does better than anything else out there in its price range.
