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.

2014 BMW Z4 offers minor refinements with a majorly orange wrapper

The redesigned BMW Z4 was rolled out onto the show floor at the Detroit Auto Show, with the example in question being an sDrive35is variant, with the just-less-than-screaming Hyper Orange Package. The exclusive colorway includes the metallic orange paintjob, as well as trim-specific seats, stitching and accents for the interior. More importantly, the 35is driveline means that you'll find a high-output version of the turbocharged 3.0-liter N54 engine, here outputting 335 horsepower and 332 pound-feet of torque, and a 7-speed DCT gearbox.
Two slightly less ferociously powered versions of the Z4 will be available for the new model year, too (both familiar). The Z4 sDrive35i is good for 300 hp and 300 lb-ft, while the still-potent sDrive28i features a 2.0-liter turbo four-cylinder making 240 hp and 260 lb-ft.

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.
