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.

2017 Audi Q7 Second Drive

One morning, I'm driving down the Malibu coast, top-down in a two-seat sports car. Twelve hours later, I'm on a straight road, in traffic, and piloting a seven-seat SUV. I think this is how new parents feel. There's no other word but "parental" to describe how three-row crossovers, like this 2017 Audi Q7, make me feel. Whether it was the Honda Pilot that was actually kind of tossable, or the plush Kia Sorento, one glance in the rear-view mirror at five headrests makes you wonder if someone isn't waiting for you outside an elementary school. The Q7, however, has always been a luxury car first. And this second-generation model is crammed with technology and convenience features to make life more effortless, as if it was designed for a person who lives in Bel Air but also must take the kids to horse-riding lessons on the one weekend it rains in Southern California. Autoblog already tested a European example, but I'm now getting the chance to finally drive it Stateside. When it comes to the Q7's appearance, I always seem to have a minority opinion. The old one looked like a bus when plenty of people said it looked beautiful. This new one has been widely criticized for looking like a wagon, but I don't see a lot wrong here. At some angles, it's reminiscent of the old 5000 Avants from the '80s – probably not a coincidence, since the Q7 is Audi's most prestigious wagon right now. Even Audi admits it pulled from the '80s with styling cues along the rear quarter panels and the ever-larger "Quattro" badges. While the shape grows on you, it isn't going to stop people seeing it and thinking it's a Q5. The new Audi Q7 has an incredible sense of elegance about it. The most ambitious design touches are the arrows in the LED lights, front and rear, but they're ultimately dwarfed by the size of the car. What's more, the string of white, silver, and gray cars on hand at our test aren't exactly striking, and the optional 20-inch wheels are boring in design. You could also call this "quiet luxury." Or perhaps stately. The new Audi Q7 has an incredible sense of elegance about it, never feeling ponderous like a truck and always feeling secure like a large luxury sedan. As the first application of the Volkswagen Group's MLB Evo platform, it really is a large luxury wagon. Which is the exact image the company seems to be running from.

Next Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.
