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.

Audi RS4 Avant Nogaro Selection puts a fresh face on old memories

I've been fortunate enough to drive plenty of memorable cars over the years, and one of my all-time favorites is the Audi RS4 sedan. It was only sold in the United States for a short time, but during that quick run, it made a huge impression on me. I remember everything about that car - the smell, the sound, the exact feeling of the manual shifter as it clicked between the six gears, and the texture of the steering wheel that I so happily tossed about. In fact, whenever I'm feeling nostalgic, I go back and watch this video of the late David E. Davis, Jr., running the California Mille roads in a Sprint Blue RS4 - a video we shot for Winding Road many years ago during my tenure as an editor there.
So even though the Audi RS4 Avant Nogaro that debuts here in Geneva isn't super important, especially for our American-centric audience, I feel compelled to write about it. No, we don't get the lovely RS4 in the States anymore, but the package offered in Europe is just as sweet as ever - perhaps even more so, what with that stylish longroof shape. Under the hood is Audi's excellent, naturally aspirated 4.2-liter V8 engine, tuned to deliver 450 horsepower and 317 pound-feet of torque, allowing for a 0-62 sprint of 4.7 seconds.
The Nogaro name refers to the special blue paint - a throwback to the original Audi RS2 Avant that kicked off the company's super sweet luxury offerings. Other unique features for the Nogaro car include gloss black exhaust outlets, window frames and grille surround, as well as matte black roof rails. Special 20-inch wheels round off the exterior enhancements, and inside, Nogaro Blue Alcantara accents can be had on the door panels and seat inners.

2015 Audi A3 TDI Challenge

I officially gave up after 758 miles. The 15 or so miles leading up to this decision were spent in the right lane of Southern California's I-8 freeway, hazard lights blinking, climbing uphill at just over 40 miles per hour. After two days of sweating to the oldies (okay, a mix of SiriusXM Classic Rewind and First Wave), I had covered those 758 miles in a 2015 Audi A3 TDI on one tank of diesel fuel. And when I say sweating, I mean it quite literally. In order to maximize fuel efficiency, my co-driver and I kept the air conditioning off, even when the direct sunlight in the California desert had outside temperatures hovering around 90 degrees. I had been doing this hypermiling exercise for two days, the car was getting stinky, and I was ready to hear the sweet "thhhhhhhwack" of satisfaction that would finally come from peeling my sweat-soaked self off the A3's leather seat. Sexy, I know.
Audi had challenged me to drive 834 miles from Albuquerque, NM to San Diego, CA, on just one 13.2-gallon tank of diesel fuel. If you believe the EPA's highway fuel economy rating of 43 miles per gallon, this means I should have sputtered to a stop after 568 miles. But I went a grand total of 758 - that's 59.4 mpg - and I could have kept going. In fact, two teams made it the full 834 miles on their one allotted tank of fuel. That's over 63 mpg. That's twenty miles per gallon better than EPA estimates.
The TDI Challenge took me through three states over the course of two days, and the 834-mile journey wasn't just a simple highway cruise. I negotiated uphill climbs, long series of involving switchbacks through the mountains and elevations that ranged from 220 feet below sea level to nearly 8,000 feet above. I learned that super-crazy-efficient driving like this an incredibly challenging game that takes serious skill. But I also learned that if you're going to attempt to stomp all over the EPA's numbers, the Audi A3 TDI is one heck of a car for the journey.
