2016 Audi A4 is larger, lighter [w/video]

The 2016 Audi A4 arrives with a bang, but no surprises. We say that because the formula for creating the new A4 is one we know all too well. Make it larger, add a bunch of content, reduce weight, and improve both power and efficiency. It's a recipe for success, and this fifth-generation A4 looks to be a solid contender against its chief rivals, the BMW 3 Series and Mercedes-Benz C-Class. The shape hasn't changed; it's immediately recognizable as an A4. Instead, this new model updates that familiar design with sharper lines, similar to what we've seen on the new Q7, or even the R8. The big story here is that the 2016 A4 is up to 264 pounds lighter than its predecessor, depending on trim and engine. Additionally, the A4 is the most aerodynamic car in its class, boasting a drag coefficient of just 0.23. A fresh, modern cabin lies within that lighter shell – one that looks decidedly more upscale than the last A4. Many elements are reminiscent of the Audi Prologue concept that we first saw (and drove) in Los Angeles last year – specifically, the steering wheel, and the new MMI controls. In fact, Audi has positioned its infotainment controls closer to the center console – in front of the gear selector. This reminds us of the current A8, where Audi specifically designed its shifter to act as a sort of wrist rest. You can rest your arm on the gear lever and still access all of the MMI functionality. Speaking of which, that's the latest generation of Audi's MMI interface, packing navigation, touch capability, LTE connectivity, and WiFi in the 8.3-inch color display. Audi isn't saying which engines will come to the United States right now, but when the new A4 launches, it'll be offered with three gasoline and four diesel engines in Europe. Our best guess is that the US-spec car will come with the latest 2.0-liter TSFI turbocharged inline-four with 272 horsepower, as well as Audi's tried-and-true 2.0-liter TDI diesel four. Front- and all-wheel drive will be available, and for the first time, two-wheel-drive models will get a proper dual-clutch transmission – no more CVT. There's a whole lot more to lean about the A4 in the press release, posted after the reveal video. You can also see the 2016 A4 in sedan and Avant forms in the galleries above and below – it's unclear if the wagon will make its way to the US. The A4 Avant has been sold here before, but currently, Audi only offers that more functional bodystyle in Allroad spec.

Audi hints at A9 flagship ahead of LA Auto Show

If you've been thinking that Audi is in need of a new design direction, you're not alone. Clean though its designs may be, they tend to be more evolutionary rather than revolutionary. But it seems Ingolstadt is on the verge of launching a new design language with a new A9 concept.
The teaser image above was obtained by Germany's Auto & Design magazine, giving us our first glimpse at the concept Audi is expected to unveil at the upcoming LA Auto Show. The concept is tipped to be based on the same MLB platform that will underpin the next-generation A8.
The concept itself could lead to a new production flagship model as well, slotting in above the A8 sedan and A7 five-door. Details remain scarce at the moment, but we'll be watching to see how this development progresses.

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.
