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 Q7 E-Tron Quattro TDI Quick Spin

The operating word is quiet. This refers both to the sound inside the cabin of the upcoming Audi Q7 E-Tron Quattro TDI – even with the diesel engine running – and the company's public statements about its plan for this powertrain in the United States. Basically, while Europe is getting the diesel plug-in sometime next spring (a bit of a delay), all we know for sure right now is that the US will be getting the Q7 E-Tron, probably in 2018, and it will have either a 3.0-liter turbodiesel or 2.0-liter turbocharged gas engine. You may now place your bets as to which one you think the public (or, more likely, CARB) will go for. We're guessing 2.0T. Despite not knowing if we'll ever see this E-Tron TDI on our side of the Atlantic, we recently spent an enjoyable morning tooling around the hills outside Madrid, Spain. As we said, this beast is seriously quiet, and impressively so. Driving Notes The Q7 is a big vehicle, but with powertrain that combines electric motors and diesel thrust, there's a ton of low-end torque. The official 0-62 time is 6.0 seconds, which is basically the same as the 6.1 seconds of the non-PHEV Q7. The Q7 E-Tron is about 500 pounds heavier than the already-4,700-pound Q7, but because of its trick powertrain, never felt sluggish in the hills of Spain. This Q7 E-Tron is a parallel hybrid, with the 3.0-liter TDI diesel engine and the 94-kW disc motor both able to drive the wheels. Overall, they provide 373 horsepower and 516 pound-feet of torque. Despite the parallel system, the not-quite-powerful-enough electric motor doesn't provide the complete electric drive experience that EV fans might be looking for. For example, the Q7 E-Tron has a top speed of 139.8 mph, but that's only in hybrid mode. In EV mode, its top speed is just 78 mph. Audi's Virtual Cockpit display, first seen in the TT, remains an ideal way to give you a wealth of information in an easy-to-see format. It's just as slick in the Q7, where you can toggle the size of the gauges and then pick what you want the screen to focus on, whether that's speed limits, infotainment information, powertrain usage, speed, or navigation.

Audi's Project Artemis woes could delay range of VW Group EVs

Two years ago, Audi's then new CEO Markus Duesmann announced his first big initiative called Project Artemis. The plan's marquee component is "to implement a new lighthouse project for Audi in record time," being "a highly efficient electric car scheduled to be on the road as early as 2024" on a brand new platform that would be shared with Porsche and Bentley. An ex-VW and -Porsche man named Alex Hitzinger, who'd also spent time at Apple working on the tech company's electric car, was brought on board to lead Project Artemis and come up with new ideas. Parent Volkswagen Group said it wanted to become "as agile as in a racing team," removing the bureaucratic molasses and bottlenecks interfering with getting the best product on the road in the best time. However, in any grand venture, failure comes before success. Automobilwoche reports that Artemis is struggling through issues large enough to push the product plans back by years. The issue, as it was with the ID.3 lineup on the eve of that car's launch, is software. Well, that's the latest, largest problem; Artemis has already been through copious struggles before getting to the software bit. Two months after Hitzinger came on, in December 2020, VW raised its EV volume target from 50% to 70% by 2030. That necessitated a rethink of the VW Group's entire platform strategy considering the far greater production scale. Hitzinger only lasted six months in the job, ousted in May 2021, supposedly because Audi believed his ideas were "not suitable for profitable series production" among other reasons. By that time, the pace of software development was already said to be six months behind schedule, with the Car.Software division working on VW.OS 2.0 "not yet running at the speed hoped for." Internal frictions were noteworthy and costly as well. VW's commercial division plant in Hanover was meant to build Artemis vehicles for Audi, Porsche and Bentley, but Automobilwoche reported in January of this year that Porsche paid a ""small three-digit million amount" — like $100 million or so — to get out of the deal mandating its vehicles come from the Hanover facility.    So Audi effectively brought Artemis in-house to lead vehicle development, and Car.Software turned into Cariad to get VW.OS and VW.AC, which stands for Automotive Cloud, to market.  The first Audi vehicle under Project Artemis was planned to arrive by the end of 2024, a production version of the Grandsphere concept.
