2014 Audi RS7 [w/video]

The subject of what makes up a true "supercar" is a difficult one, fraught with personal connotations and the rare ability to bring close colleagues into heated confrontation with one another in the blink of an eye. I say this because, while the 2014 Audi RS7 most certainly does not make the supercar cut on a few levels to my way of thinking - not rare enough, expensive enough or wearing an appropriately evocative body - it is unquestionably an "everyday supercar" of remarkable ability. And, pertinently, it is one that proved willing to ply its trade in every version of winter that Michigan had to offer it.
I had winter four ways during my week-long loan with the RS7. A period of crisp temperatures and dry roads, presided over by light blue skies as wide as the horizon, soon gave way to spitting, freezing rain blanketed in slightly misleading warmer air. Then there was snow. Not the massive blanket we saw in the first week of the New Year, but more than enough to see my neighbors stocking up on Ice Melt and replacing their shovels for the season. Finally, temperatures dropped to the mid teens, cottony snow compressed into a hard pack and all residual moisture on the mostly cleared roads morphed into the very slickest of ice. Timeless curses were uttered by cranky commuters in smoking breaths. Pure Michigan.

2015 Audi A3

The five-door Audi A3 hatchback, on sale in the States since the 2006 model year, never earned the respect it deserved. Despite possessing the automaker's well-regarded build quality and a range of strong powerplants (including an excellent diesel option), the entry-level model always played second fiddle to the rest of the Audi lineup, suffering from less innovative technologies and fewer premium options on its list. Many buyers considered it inferior to the rest of the models in the company's showroom. But those misconceptions could be about to change, as Audi is in the midst of introducing its third-generation A3 family to the States with expectations that the range will finally align with the rest of its portfolio.
First to arrive is this new sedan, notable as it is the first time the A3 has been offered as a compact four door. The new bodystyle is positioned as a premium C-segment offering, with its most obvious competitor being the new Mercedes-Benz CLA-Class (BMW has not officially announced a 2 Series Gran Coupe, which would be the third entrant in the segment). The automaker says its "A3/S3 models will be among the most technically advanced Audi products around" and there will be "no sacrificing Audi craftsmanship and premium appointments." To put the automaker's claims to the test, we spent a week with this new sedan in Southern California.

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.
