Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

Audi mulling producing version of Quattro showcar, just not sure which one [w/poll]

Head of design for Audi, Wolfgang Egger, has told Auto Express that a reborn Quattro could enter production, but bosses for the company haven't yet decided whether to base it on the Sport Quattro concept that just debuted at this week's Frankfurt Motor Show or the smaller Quattro concept that was revealed at the 2010 Paris Motor Show.
While both draw their inspiration from the original Ur-Quattro of the 1980s, they vary wildly in both size and choice of powertrain. The 2010 Quattro concept was based on Volkswagen's MQB platform, shared with such vehicles as the Golf and Audi A3. The Sport Quattro, meanwhile, was built atop the company's larger MLB platform that's used almost exclusively for Audi models, including the A5, which is also a coupe.
Under their hoods, the 2010 Quattro concept simply employs a version of the same 2.5-liter engine used in the TT RS, tuned to deliver 408 horsepower, while the Sport Quattro goes nuclear with a twin-turbo V8 hybrid powertrain that develops 700 hp and 590 pound-feet of torque. Both, of course, employ quattro all-wheel drive just like their forebearer.

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.
