2014 BMW 4 Series Convertible is easy, breezy, beautiful

BMW debuted its 2014 4 Series Convertible today at the LA Auto Show, and the sporting two-door will feature a folding hardtop - like the convertible 3 Series before it - and be offered in 428i and 435i guises.
The 428i Convertible is equipped with BMW's 2.0-liter turbocharged inline four-cylinder engine, which pumps out 240 horsepower and 255 pound-feet of torque - good for sprinting from 0-60 miles per hour in 6.2 seconds. The 435i Convertible gets the 3.0-liter turbocharged inline six-cylinder engine, which steps up output to 300 hp and 300 lb-ft of torque. The topless 435i drops the 0-60-mph time to 5.5 seconds. Both cars come standard with an eight-speed automatic transmission, and BMW says that a manual transmission will not be offered on 4 Series Convertibles in the US market.
The 4 Series Convertible will be offered in Sport Line, Luxury Line and M Sport trims. Pricing starts at $48,750 for the 428i Convertible and $54,900 for the 435i. Head on below to peruse the (long) press release for details.

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.

2014 BMW Z4 sDrive35is

The BMW Z3/Z4 roadster has never really had a widespread following because it has either been too humble and small a roadster (albeit with some fun and very low-volume M editions) or it has been - in this E89 generation - too casual an image leader with no racier aspirations. The current 480-hp Z4 GTEs don't count, since they are as stock a Z4 as today's Pamela Anderson is the same blonde actress we knew as Heidi on Home Improvement. You know, sort of like those ever-so-slightly modified Toyota Camry coupes competing in NASCAR.
The ultimate highpoint for the BMW Z roadster franchise was at the very start of its life in the mid-90s, in the James Bond film GoldenEye with Pierce Brosnan. The Stinger missiles that Q's team installed behind the Z3's headlights were never fired, and BMW never even offered this self-defense package as an option. Yet another case of the ol' bait and switch.
And in all these subsequent years of Z3s and Z4s strutting their long-hooded stuff, the little sporting Bimmer could really have used a live Stinger missile or two to spice things up. The current Z4 exists, it is pretty dang sexy, and BMW seems content to let it linger there. We just drove the new midlife version of the roadster near BMW headquarters in Munich, and it served to reinforce our feelings.
