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.

More details on next Audi A4 mooted, including PHEV

With just under two more years until the next-gen Audi A4 hits the streets, it's not surprising that details are starting to leak out. The Brits from Autocar are reporting some information on the 2015 A4, although it isn't clear where any of it came from.
The most substantial news might be in regards to the plug-in hybrid version of the car. We've known for a couple years now that an A4 PHEV was being planned, but the report indicates that a trio of plug-in configurations are being planned, equipped with a 2.0-liter gas engine, a 2.0-liter diesel engine or a 3.0-liter supercharged V6. All engines will be paired with an eight-speed automatic transmission, and the A4 plug-in is said to have an all-electric range of up to 31 miles.
In terms of styling, the next A4 shouldn't stray too far away from Audi's current design language, but it will introduce a new version of the automaker's signature grille. Despite being about the same size as the existing A4, the fifth-generation model will drop some pounds thanks to various weight-saving techniques with the most obvious being aluminum body panels. Based on this info, we should see the A4 sedan and wagon in April 2015, an Allroad later in the year and a redesigned A5 lineup hitting the scene in 2016.

Audi Airomorph is a sleek shape-shifting senior thesis

Eric Kim just graduated from the from the Art Center College of Design in Pasadena, CA, at the end of the spring 2014 semester, and for his senior thesis project he came up with this futuristic Audi endurance racer called the Airomorph. He even got some input Audi designer Kris Vancoppenolle.
The Airomorph imagines a future Audi racer for Le Mans that features adjusting fabric panels to fine-tune the car's aerodynamics as it laps the course - a technology inspired by catamaran racing. "I started from scratch and had the freedom to deliver and execute a white space design for the future," said Kim to Autoblog via email. It's also somewhat similar to the idea behind BMW Gina concept, although Kim says that wasn't an inspiration for his design. The body here is made from a single piece of a silver, expansion-resistant material stretched over a frame underneath. The fabric anchors at the wheels, front and rear section with movable cables, and hydraulic actuators pull the wires to shift the aero as needed.
The actual shape echoes Audi endurance racers from the past and present. In profile, you can easily see the current R18 with its arcing cockpit and fin down the rear. Of course, that's interpreted through a little bit of Blade Runner with the covered wheels sticking out from the body. The front shows the rectangular shapes from the earlier R15. There doesn't appear to be any way to actually see out of the vehicle, though.
