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.

Audi R8 lines up as safety car for Rolex 24 at Daytona

This weekend a new era begins in American sports car racing with the Rolex 24 at Daytona to kick off the new United SportsCar Championship, the freshly inked union between the Grand Am and American Le Mans Series. There'll be a wide variety of machinery lining up on the grid at the Florida speedway, including race-ready versions of the sports cars you can drive on the road, plus Daytona Prototypes, Le Mans Prototypes and even the DeltaWing. But at the front of the pack will be the Audi R8 5.2 FSI.
That's because Ingolstadt's flagship has been named as the official safety car for this, the 52nd annual Rolex 24 at Daytona. And so the R8 becomes the first pace car pressed into service for the United SportsCar Championship, although the model also paced last year's race (pictured above) when it was under the auspices of the Grand Am series.
The car in question appears to bear little in the way of modifications over the showroom version, save for some requisite graphics and maybe some emergency lighting to make it more visible - because while you wouldn't miss an R8 slicing its way through ordinary traffic on the road, it's another story entirely in a field full of competition machinery. Audi points out that the road-going R8 shares a good 50 percent of its components with the R8 LMS competing in the race, including its 5.2-liter V10 engine that's available this year with a new seven-speed dual-clutch transmission.

Refreshed 2015 Audi A8 starts at $77,400*

Audi definitely made the US wait for the refreshed 2015 A8 and S8. The updated models were first unveiled last summer, but it has taken until June for the revised flagship sedan to reach dealers here.
The refreshed A8 line doesn't come cheap, though. Prices are up $2,000 or more over the 2014 model year. The basic 3.0T model goes for $77,400 or $81,400 for the long wheelbase version. The long wheelbase TDI is $85,100. The standard 4.0T model asks $86,400 or $90,400 for the longer one. An S8 sets back buyers $114,900, and the full bore A8L W12 is $137,900. All of these prices exclude destination (which was $895 last year and now stands at $925, according to Audi representative Mark Dahncke).
To make the wait worth it, Audi is packing the sedan with new technology and given it the slightest restyle. All models of the luxurious vehicle now come standard with full LED headlights. The 2015 model also benefits from electromechanical steering, available variable ratio steering and active lane assist. The night vision system is also updated to detect animals and alert the driver. Mechanically, there are some tiny tweaks as well. The 4.0T V8 is boosted to 435 horsepower, compared to 420 hp previously, and the 6.3-liter W12 now has cylinder deactivation.
