BMW dishes on 'lightweight' 2014 M4

BMW's M cars are not what we'd call featherweights. Sure, the big, bruising twin-turbocharged V8s deliver a lot of power, but the fact of the matter is that more weight often equates to less fun.
Which is why we're so excited over a recent sit-down the blokes at Top Gear had with BMW's product manager for small and medium cars, Matt Collins. The chat led to talk of the M3 Coupe replacing M4. Collins confirmed that, yes, the new M4 would be turbocharged. The new engine will also be a six-cylinder, which should make purists happy.
"What we'd like is more focus on lightweight engineering." -Matt Collins

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 2 Series specs leaked?

Thanks to spy shots from earlier in the year, we already know what the new BMW 2 Series will look like, but now we know a lot more about the coupe courtesy of an apparent BMW South Africa error and some quick-clicking enthusiasts. Though the information no longer appears to be posted on BMW's South African website, 2addicts.com managed to grab most of the details for the new coupe, including the model lineup, specs and most (if not all) of the options list for the upcoming replacement for the 1 Series.
Just like the latest 3 Series, the 2 Series model lineup starts at the 220i powered by a 2.0-liter inline four-cylinder, but the more exciting BMW figures to be the M235i with its 320-hp, 3.0-liter straight-six. With the automatic transmission, the info says that the M235i weights 3,240 pounds and will be able to accelerate from 0-62 miles per hour in 4.8 seconds - making it both lighter and quicker than the 135is currently offered in the US. The base 220i coupe should also be fun to drive with its 180 horsepower and sub-3,000 pound curb weight.
A quick side-by-side comparison of the dimensions for the base 220i with our current base 128i shows that the new coupe rides on a longer wheelbase (105.9 in. vs. 104.7 in.), is about two inches longer (174.4 in. vs. 172.2 in.) and is an inch wider (69.8 in. vs. 68.8 in.). 2addicts.com even shows available paint colors, interior trim options and lists pricing for South African-spec models. Head on over to the forum to check out all the info they have posted, but we expect the 2 Series to be unveiled at the Detroit Auto Show early next year.
