Next Audi Q7 to debut with electric turbocharger?

For years, the concept of an electric turbocharger was essentially a joke sold on eBay to boost power in your slammed Civic, but in the last five years it has moved from an idea on a piece of paper to a feasible reality. Audi has already toyed with a showcase of the cutting-edge tech in road cars with the RS5 TDI concept. Now, reports suggest an electric turbo may make it to the streets as soon as next year in the next-gen Q7 (spy shot pictured above).
"I can confirm we are working on the development of the e-boost definitely," said Ulrich Weiss, Audi's diesel engine boss, to Australia-based Drive. He didn't give an exact timeframe but hinted at sometime next year, possibly in the Q7. He also suggested the chance of an RS-branded diesel model in the vein of the RS5 TDI concept on the horizon, as well.
This tech isn't entirely new for the folks in Ingolstadt. Audi's R18 endurance racer already uses such a system to capture waste heat from the engine, converting it to electric power to further power the hybrid car. The RS5 TDI concept employs a similar idea with a 3.0-liter, twin-turbocharged V6 with an electric supercharger to make up for the turbo lag. It's able to pump out 385 horsepower and 553 pound-feet of torque and allegedly sprint to 62 miles per hour in four seconds.

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 S8

You've gotta hand it to the Audi A8. Last year, Mercedes-Benz launched the truly stunning S-Class, putting the rest of the high-dollar luxury flagship class on notice. With the brand-new S-Class turning heads and garnering all sorts of praise from the automotive press, classmates like the BMW 7 Series, Jaguar XJ and Audi A8 started to look, well, old. But Audi didn't see fit to just let its big sedan carry on and let the Mercedes take the cake.
So when Audi refreshed its A8 line for the 2015 model year with only minor updates, I kind of shrugged it off as just a quick way to keep the big sedan fresh until an all-new, hopefully S-Class-trumping version arrives. But then I drove the S8 pictured above, and I'm no longer so sure the Merc's shadow is as big and imposing as it once was.
Spoiler alert: the Audi S8 is simply fantastic.
