BMW M4 spied in coupe and convertible form

From the sound of it, we'll have to wait until the Detroit Auto Show to see the production version of the BMW M4, but spy shots show the new hi-po BMW testing recently in both coupe and convertible form. Showing a lot more skin than recent spy shots, these M4 prototypes look very similar to the M4 Concept we saw at Pebble Beach.
Carryovers from the concept car include the funky mirrors, bulging hood and the slotted front fascia vents, but the rear fascia seems to be missing the added flair of the concept and, as expected, the carbon fiber front splitter and exhaust tips are also missing from these M4s. Like the current M3 Convertible, the drop-top version of the M4 will utilize a retractable hard top.

2015 BMW M3 and M4 configurator launched, no lunch hour safe

BMW has just made your lunch break a little more interesting by launching the configurators for the M3 and M4. Pricing and options for the new sports coupe and sedan was revealed just a few days ago, but it's always more fun to see the visual effect your personalizations have on the bottom line.
The M3 and M4 start at $62,000 and $64,200, respectively, without a $925 destination charge. However, as soon as the configurator is opened, both models default with metallic paint ($550) and the M Double-clutch Transmission ($2900), plus extended leather on the M3 ($950) and full leather on the M4 ($3,500). This is basically the way they were shown when displayed at auto shows. Of course, there's nothing preventing users from setting up these performance machines however they like.
So sit down at your desk with a cup of coffee or a sandwich and create your perfect German sport sedan or coupe. It's always fun to see how much money can be spent on a dream car.

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.
