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 apparently still undecided about future i project electric vehicles

Coaches like to say that there's no "i" in team. At least one BMW executive is saying the company's not sure if there are any more "i"s in its near future. BMW executive Harald Krueger indicated that the German automaker is holding back on any i-project plans besides the i3 city car and i8 plug-in hybrid sports car until the company gets a better idea of how those models are selling, Reuters says. Bimmer has spent about $2.7 billion on the plug-in sub-brand and says it's taken more than 11,000 orders for the i3 since the model was first shown off at German dealerships last fall. Additionally, BMW has no plans to make the i3 in China (BMW makes versions of its 3- and 5-series sedans there). As we all know, should the brand expand, BMW has already trademarked the "i" badge from i1 through i9. There are a lot of mixed messages on the BMW i project front. For example, early indications are that i3 demand has been higher expected. BMW North America chief Ludwig Willisch indicated earlier this month that US demand for the electric city car, at least for the near future, will likely to outstrip supply. Bimmer dealers in the US will start getting the $41,350 i3 in May. Additionally, fellow BMW executive Jacob Harb said the company was already starting to work on its next EV, to be larger than the i3, though he didn't give many details and was later somewhat refuted by another BMW spokesman.

BMW almost ready to roll out new 2 Series cabriolet

The 2 Series is a relatively new member of the BMW family, having been spun off of the 1 Series (itself one of the company's youngest lines) just last year. So far the range has been split between the Active Tourer and the 2 Series Coupe, but soon the latter will breed a new compact convertible to take the place of the outgoing 1 Series cabriolet, and here we have our best look at it yet.
Spied with the most minimal camouflage and its top down while undergoing its final rounds of development testing, this pre-production 2 Series cabrio looks about ready for show time. While the Active Tourer is based on a different front-drive platform, this convertible is, as you might have guessed, essentially a 2 Series Coupe with a folding fabric roof. That means rear-wheel drive (or potentially all-wheel drive if BMW extends its availability from the coupe to the convertible) win either 228i or M235i specification - both of them turbocharged, the former with a 240-horsepower, 2.0-liter four and the latter with the 320-hp, 3.0-liter inline-six.
Considering that BMW got an approximately $8k premium for the 1 Series convertible over the coupe, expect the 2 Series cabrio to start at a little over $40k for the 228i and top out at around $53k for the M235i xDrive convertible. That is, assuming BMW offers it in that top spec, because at that rate we're getting perilously close to the $54,900 base price of the 435i convertible.
