BMW 4 Series production coupe caught on commercial shoot

Despite filming at 2:00 AM and at an undisclosed location, BMW minders filming a commercial for the fast-approaching 4 Series coupe were unable to ward off the long lenses of spy photographers. The result, as you can see here, is our first-ever look at the production version of BMW's new coupe, completely uncovered.
The night shots may be a little bit grainy, but the fast-moving 4 Series still looks pretty good with its camo closeted, matching the svelte lines of the concept car we saw in Detroit this winter. Expect that the 4 coupe will come to market with a turbocharged 2.0-liter four-cylinder in 428i trim, and a turbocharged 3.0-liter six-cylinder in 435i spec.
Take your time looking through our gallery of movie-star 4 Series photographs, and tell us what you think about the uncovered Bimmer, in comments.

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 CS reinterpretation proves retro can be sexy [w/video]

Designer David Obendorfer doesn't work for BMW, but perhaps the German automaker should give him a call. His CS Vintage Concept shows a singular ability to understand the brand's classic style and reinterpret it for today. He isn't some amateur, either. Obendorfer has an industrial design degree and has been penning the interiors and exteriors of yachts from the Officina Italiana Design for five years, which counts luxury shipbuilders like Riva and Sanlorenzo among its clients. His website shows a real passion and knack for modernizing '60s and '70s European cars, too.
Obendorfer prefers to reimagine classic automotive styles. "Retro cars are not copies of their predecessors or renovated specimens, rather they are carefully studied reconsiderations, strongly rooted in contemporary style," he tells Autoblog. For the CS Vintage Concept, he worked to update the looks of the seminal BMW 2000CS and its E9 chassis while placing them on a modern platform. Obendorfer's inspiration comes from his belief that the later CS models' design is partially responsible for defining BMW styling, with its shark-nose front and four round headlights.
The CS Vintage Concept's shape starts with a jutting hood and a quartet of LED headlights, but the whole design really comes together in profile. The Hofmeister Kink at the rear pillar with the BMW Roundel is a nice nod to the originals, yet the proportions still find the perfect fusion of classic and modern. The interior is minimalist, with a vast expanse of wood for the dashboard at first glance, but the latter opens to expose the car's infotainment system.
