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.

Next Audi A7 redesign will include more traditional rear end

A report in Automobile says that Audi is rethinking the design of the next A7. Audi told Car and Driver that owners "have trouble with the radical tail of the A7," so its model-defining rear end will give way to something more traditional. Automobile is light on specifics of the redesign, but the general direction is "a lower, wider, and more expressive shape." The philosophy behind the dimensions and styling is a "C/D shift," meaning Audi wants to give its C-segment hatchback the bearing, gravitas, and visual delight of a D-segment vehicle. That would help the A7 stand out from its in-house competition, and could make for higher transaction prices. Having heard about different design directions from Audi for years without much in the showroom to back it up, we could define what we'd love to see in two words: more Prologue. This is Audi, so you know the next A7 will be packed with tech. We expect an emphasis on touchscreen interfaces, a digital dash cluster a la the TT that moves with the steering column, a HUD with night vision, and an MMI system a few more steps down the evolutionary trail. Engines will see some upgrades like the addition of a plug-in hybrid, the excellent 2.0-liter, turbocharged four-cylinder getting a 74-horsepower e-boost assist to 326 horsepower, the 3.0-liter V6 slated for the S7 rising to 500 hp, and the 4.0-liter V8 in the RS7 pumping out 575 hp.

Meet the first of four Audi A4s coming to our long-term fleet

Yes, you read that right, this is the first of a quartet of A4s we'll be looking at over the course of the year. We're kicking things off with an Audi A4 Premium Plus sedan, and we'll be looking at other iterations of the A4 line later on: the A4 Prestige, Allroad, and S4. What we hope to do is provide you with a thorough examination of each variation, and hopefully give you some guidance on what's worthwhile and what isn't. But first, let's introduce you to the A4 Premium Plus. What we got The A4 Premium Plus is the middle child of the standard A4 line, fitting between the entry-level Premium and the top level Prestige. Stepping up to the Premium Plus adds 18-inch alloy wheels, LED headlights, an S Line body kit, Bang & Olufsen sound system, parking sensors, aluminum window trim, and heated power seats with memory. The model we received from Audi has a number of upgrades that bring it quite close to the Prestige trim level. Most notable is the Technology package, which adds the Audi Virtual Cockpit instrument panel, which replaces the physical gauges with a big LCD screen. It also comes with rear cross traffic alert. A First Edition package was added, too, which adds cooled sport seats, a three-spoke steering wheel, and unique wheels and aluminum interior trim. Our favorite part, is the sport package, which adds sportier suspension, a black headliner, and the aforementioned sport seats. What we skipped Really, we didn't skip much here – this particular A4 Premium Plus is pretty loaded. The only packages not included were the Cold Weather package, which includes heated rear seats and steering wheel, and wheel and tire options. The heated steering wheel isn't necessary since winter is almost over (at least we hope). The cost of these packages added up fast, too. Moving up to the Premium Plus trim over the standard Premium added $3,800. The Technology package was $3,250, the First Edition package was $1,100, and the Sport package tacked on $750. Along with the white paint at $575, our Audi has over $9,000 in options. That brought our tester up to $49,825 from a base MSRP of $40,350. We like everything that's been added. If we were to pick packages we could live without, though, we'd probably pick the Technology and the First Edition packages. As slick as the LCD instrument panel is, there's nothing wrong with physical needles and dials.
