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.

The 2017 Alpina B7 xDrive isn't as cool as the BMW M760i

Steve Ewing is good people, but when it comes to big BMWs, he talks nonsense. He argues, incorrectly, that the new Alpina B7 is somehow cooler than the new M760i. Here's why he's wrong. No surprise, but the bulk of the pro-M760i argument comes from under the hood. Yes, both cars produce 600 horsepower and 590 pound-feet of torque, but it's where the power comes from that really matters. The M760i's power is just much more accessible, with peak torque coming in at just 1,500 rpm, while the Alpina makes owners wait until 3,000 rpm for max twist (a fact Ewing glosses over). The V12 also offers up all 600 horsepower at 5,500 rpm, 250 rpm earlier. Sure, the Alpina is 0.3 seconds faster to 60 miles per hour – it does the deed in 3.6 seconds to the M760's 3.9 seconds – but it relies on a tweaked transmission setup to do it. Not only that, but big automakers like BMW are usually quite conservative about performance figures, so it's still a bit early to hand a medal to the aftermarket. Here's the other thing about the engines – Nigel Tufnel would prefer the M760i. See, the Alpina has a 4.4-liter, twin-turbo V8, but the M760i has a 6.6-liter, twin-turbo V12. To paraphrase Tufnel, "This one has a V12." We rest our case. Other changes between the two cars are largely in the eye of the beholder – we can talk about the transmission, suspension, and xDrive changes until we're blue in the face, but we simply don't have enough information about the two setups to make substantive arguments – some people might prefer the subtler styling of the M760i. We're not going to blame anyone for liking the more aggressive look of the Alpina, with its big, quad-tipped exhaust, meaty front splitter, or aggressive side sills. And those 21-inch Alpina wheels? Easily the coolest styling detail. You can get a closer look at them, and the Alpina's other changes, in our live gallery from the floor of the Geneva Motor Show.

Acura TLX Type S vs. BMW M340i xDrive | Sport sedan comparison test

Luxury sport sedans are still turning up on the market, and the Acura TLX Type S is one of the freshest cuts of meat in the window. It’s AcuraÂ’s big return to Type S performance models. Benchmarked against the proverbial best performance sedans of the segment, Acura is aiming to not just to compete, but to win dogfights like these. To see if the return of Type S is all itÂ’s cracked up to be, we decided to pin it up against the historical king of sport sedan shootouts: a BMW 3 Series. Specifically, the Type S is taking on the M340i xDrive, which is this AcuraÂ’s most natural competitor from Munich. Should the diehard BMW driver make the switch to Japanese performance? Does Type S do enough to lift this Acura up to best GermanyÂ’s finest? There are a lot of variables at play here, and they all make it complicated to choose a winner. The similarities between these two begin from the top of the spec sheet and go down. Both have 3.0-liter turbocharged six-cylinder engines — BMW arranges its cylinders inline, while Acura chooses a V configuration. Quick-shifting automatic transmissions are standard. BMW uses an eight-speed unit, while Acura uses a 10-speed. Both get electronically-controlled dampers, big brakes and sticky summer rubber. They each offer up usable backseat space and reasonably-sized trunks. WeÂ’d feel just as confident showing up to an important business meeting in either one as we would at a track day. ThatÂ’s the beauty of this mid-tier performance segment. After looking at their specs, it shouldn't be surprising that the M340i is the quicker of the two here. Its 382 horsepower and 368 pound-feet of torque hit noticeably harder from any speed than AcuraÂ’s 355 horses and 354 pound-feet of torque. The Acura is also carrying an extra 232 pounds of curb weight over the Bimmer, which makes the M340iÂ’s 1-second advantage in the 0-60 mph sprint make perfect sense. For the record, BMW quotes a 4.1-second time, and Acura only offers an approximate time of 5 seconds. Both estimates feel accurate. Beyond sheer acceleration, both engines offer up their own version of tingly feel-goods. BMWÂ’s inline-six is as smooth as ever as it plays its sonorous note all the way to the 7,000 rpm redline. There are few sounds in the automotive universe that surpass the glee we feel when listening to a BMW inline-six at full-chat, and that rule still applies to the M340i.
