Audi SQ7 coming, will have electric turbo

Formula 1 and endurance racing are already harvesting energy from turbos on the track, and now it's apparently time for a similar idea of boosting the efficiency of forced induction to hit the streets in a high-performance, diesel SUV.
In a recent interview with the UK's Autocar, Audi technical boss Dr. Ulrich Hackenberg let the big news slip. "The new Q7 will be available in the market next year but the electric turbo will come a bit later in the Audi SQ7 available in 2016," he said. The e-turbo system was already rumored for the premium SUV but for the standard model, not this just-announced performance version.
Audi has been experimenting with the e-turbo system for a little while, as an electrically driven supercharger. It showed up on the RS5 TDI concept that used a 3.0-liter, twin-turbocharged diesel V6 plus the electric system to diminish turbo lag. In that application, it provided an impressive 385 horsepower and 553 pound-feet of torque and an alleged sprint to 62 miles per hour in 4 seconds. Although, Dr. Hackenberg didn't make it clear if this was the exact layout for the SQ7.

AMS Alpha 10 Audi R8 First Drive [w/video]

Horsepower is a relative number. Compared to the 1,500 hp in the last AMS car we drove, the face-melting Alpha 12 GT-R, 900 seems pretty tame. But by any rational standard that's a crazy amount of power, the kind that's hard to grasp in practical terms. When AMS Performance called us and offered a test in the 921-hp Alpha 10 Audi R8, saying yes was easy. Figuring out how to demonstrate that much thrust was the tricky part. Our solution was to head to the drag strip. What better way to show off the wicked alterations wrought by AMS president Martin Musial and his team than a video showing the car do the Star Trek warp speed effect through the quarter mile? AMS has a history of building quick drag strip cars, like the aforementioned GT-R and a series of Mitsubishi Lancer Evolutions. Vice president Arne Toman even owns the world's fastest Hearse. We should have taken the broken scoreboard at Milan Dragway as an omen. Wiped out by a lightning strike, both displays have since been replaced. Before our test both Musial and Toman explained that the Alpha 10 R8 wasn't built with drag racing in mind. But, being good sports, both met us at the track in southeast Michigan, unloaded the R8 from its trailer, and let us run through the timing lights over and over. The best time that day was 11.0 seconds at 136 mph, uncorrected. One of the many amazing things about the Alpha 10 Audi R8 is that it's essentially a bolt-on system. That's fast, but not what you'd expect for 786 horsepower at the wheels. And, honestly, we're not disappointed. First, a 4,200-rpm rev limiter was set too low to launch on the sticky drag strip. Put another way, that drag strip time is almost a street start. For what it's worth, Musial and Toman didn't seem concerned about the numbers. Like we said, they present the Alpha 10 as an all-around performance car, and we believe them. Now, if you go to AMS with the drag strip in mind, Musial and his staff can program whatever launch rpm you desire. (You're on your own for clutch replacements.) A reflash of the engine controller is part of the Alpha 10 package. Drop off a stock R8 V10 at AMS (or any of its 70-plus dealers), and they'll pull out the suitcase-shaped muffler that sits behind the engine. A pair of turbochargers, small mufflers, and two heat exchangers attach to the stock exhaust system mounts, while a giant water-to-air intercooler sits on top of the engine.

Production 4.0: Audi plans for the smart factory

Automotive production is becoming more integrated and at the same time has to be more intelligent and more efficient. Flexible production of customized vehicles is one of the big challenges for the future, especially for a premium carmaker like Audi. How will the "Vorsprung durch Technik" brand meet its aim of offering premium quality with added custom flexibility? The company sees the "smart factory" as the key. Whether it's body-color moldings or light-alloy wheels in a special size, almost every car is ordered with some kind of customization, and the demands are increasing. This requires of course already a lot of flexibility. While the variety of models and quality demands are increasing, automotive manufacturers such as Audi are eager to make production sustainable. In an Audi interview, innovation management members Alois Brandt and Henning Loser talk about "production 4.0" and the upcoming "smart factory." How will Audi manage the production site with its very high standards of quality, efficiency, and environmental acceptability? Will the so-called "smart factory," which should be the intelligent factory of the future, only employ robots? Alois Brandt: "With a deep look into the production, I am convinced that our employees and not machines are the relevant working forces behind the Audi brand. Machines can be bought anywhere." Increasing digitalization is paving the way for the smart factory – the intelligent, digitally connected production facility. New high-tech solutions in manufacturing should further increase the high level of quality, while at the same time the assembly work should be easier and result in better ergonomics. Can you give us a clearer imagination of the "smart factory"? Alois Brandt: "There are a lot of ideas. But the big question at the moment is: Which one is really needed and leads into the right direction?" Can you tell us a little bit more about "production 4.0"? Alois Brandt: "The assembly line as we know it in the present will no longer play the same role. If it makes sense, it will be terminated and replaced by – let's call it – a virtual assembly line. The production will be more modular than before and the car will be directed to a production point – a so-called 'island of competence' – where it is needed." Henning Loser: "If the vehicle is to be assembled to the customer's wishes, it is obvious that efficient programming of robots and coordinating with the human workers is needed.
