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 pits S3 against Ur-Quattro on gravel

If you had to pick a winner between the latest Audi S3 and the original Audi Sport Quattro, which would it be? Both hot hatches pack around 300 horsepower and all-wheel drive, but they're separated by a good thirty years of development.
To find out, Audi took both to the old rally circuit in San Remo. Behind the wheel of the Ur-Quattro they put none other than The Stig himself - no, not the Top Gear test bot, but Stig Blomqvist, the Swedish former rally driver who drove the Quattro to the World Rally Championship in the mid-80s. In the S3 they put someone named Hermann Müller, who as best we can tell was one of Auto Union's original Silver Arrow drivers - but he died in 1975, so it's probably the guy who writes for the Audi magazine. Regardless, the contest was pretty close, so it's worth checking out in the 2:26 video clip below.

Audi recalls A6, A7, and A3 in two airbag-related campaigns

Audi will recall a total of 21,978 vehicles in the US across two campaigns. The Basics: Audi's larger recall covers 21,074 examples of 2012-2013 A6 sedans with manufacturing dates between March 28, 2011, and March 25, 2013, and the 2012-2013 A7 models built between January 25, 2011, and March 19, 2013. The Problem: In examples of the sedans with heated and cooled seats, the Passenger Occupant Detection System can malfunction and prevent the passenger's side airbag from deploying in a crash. Injuries/Deaths: None reported. The Fix: Dealers will repair the Passenger Occupant Detection System. If You Own One: Audi will begin the recall in February 2016. The Basics: In the smaller safety campaign, Audi will recall 904 examples of the 2015 A3 Cabriolet built between June 5, 2014, and April 1, 2015. The Problem: The driver or front passenger seat covers might not have the correct stitching, and this could prevent the side airbag from properly deploying in a crash. Injuries/Deaths: None reported. The Fix: Dealers will replace the seatback covers on affected seats. If You Own One: Audi will begin the recall in February 2016.

REMEDY: Volkswagen will notify owners, and Audi dealers will install a PODS system repair kit, free of charge. The recall is expected to begin in February 2016. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 74D1.
