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.

2015 Audi RS7 Dynamic Edition strutting to NY

The Audi RS7 is already one of the most stylish sports sedans (hatch, wagon, whatever...) on the road today with flowing roof and hunkered down appearance. Now the German automaker is taking that formula even further with the introduction of the RS7 Dynamic Edition at the 2014 New York Auto Show, and the addition of a long list of unique options.
When it goes on sale early this summer, the Dynamic Edition won't come cheap. Prices start at $146,045, which is $41,145 over a base RS7. The extra money allows opulent additions like Black Valcona honeycomb-stitched leather sport seats, Crimson Red seatbelts and interior stitching, Tornado Red brake calipers with the RS7 logo, Audi's Dynamic Ride Control suspension and a sport exhaust. It rides on 21-inch, five-spoke wheels with Gloss Black accents. Also carbon fiber pieces replace the front splitter, rear diffuser and engine cover.
The DRC suspension is a late addition to the RS7's options list and comes standard on the Dynamic Edition. It uses three-stage adjustable dampers that are cross-linked and integrated into the driving mode selection and rear differential.

Mattias Ekstr?m unleashes bonkers 600-hp Audi S1 Supercar on World RX

Mattias Ekström doesn't need to prove anything. He's won the DTM title twice and before that the Swedish Touring Car Championship. But being a racing driver as he is, Ekström has been looking for new challenges. He's contested the Swedish Rally six times, the German Rally twice, he's driven in V8 Supercars and in NASCAR. He's even won the Race of Champions. Twice. Heck, we're surprised his long-time sponsor Red Bull hasn't let him try out one of its F1 cars. But this season it's on to a new challenge: the inaugural FIA World Rallycross Championship.
Ekström drove a Volkswagen Polo fielded by Marklund Motorsport in the Swedish rallycross round last season and came in second, but this year he's diving in head-first with his own team and his own car. His outfit EKS is hard at work preparing the new Audi S1 for competition in the World RX Championship, and will field two of them this season: one for Ekström and another for JWRC champion Pontus Tidemand.
Built to compete in the top category of the championship, the EKS Audi S1 Supercar will pack a 2.0-liter turbo four with 600 horsepower, all-wheel drive and a 0-60 time of 1.9 seconds. It's expected to make its debut late in May at the World RX of Great Britain where it will have to tangle with specially prepared versions of the Citroën DS3, Ford Fiesta ST and Peugeot 208 driven by the likes of Tanner Foust, Ken Block, Jacques Villeneuve and Petter Solberg. The sole North American round will be held in Trois-Rivières, Quebec, in early August, on the same circuit that once hosted Indy Lights, ALMS, Grand-Am, Can-Am and Trans-Am races.
