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.

Porsche, Audi team up for tech: autonomy, EVs, hybrids and more

Porsche and Audi have been working on a number of important technologies for future vehicles. The two luxury automakers, both part of the Volkswagen Group, have mostly appeared to guard the space between their brands despite some shared engines and a platform. While their goals may not always overlap – Porsche has shied away from fully autonomous driving, for instance ­– the two brands have decided they could move more quickly into their respective futures by putting their heads together. In that spirit, Audi and Porsche are partnering up for a "shared vehicle architecture strategy of the future." This collaboration will focus on future mobility, including the development electrification, digitization, and autonomous driving technology. And the teams have knowledge and resources to share with one another. Porsche is moving fast with electrification, adding more hybrid systems to its models and preparing to launch the ultra-fast-charging Mission E electric car. Audi has been pursuing autonomous driving, connected vehicle and V2X tech, and Shared Fleet programs. Combining the best and brightest of both companies should help accelerate R&D. Even if one or the other company doesn't put all of the co-developed technologies into its vehicles, they'll both be learning the lessons, and sharing resources should help keep costs in check. "We will cooperate wherever it makes sense," says Porsche Board of Management Chairman Oliver Blume. "But we will also be very careful to maintain the differentiation between our brands. A Porsche is always a Porsche, and that will remain so in the future." Detail are still scarce, but Audi and Porsche will pin down a more a more specific sharing strategy as they develop their plan through 2025. While the cars continue to look and drive differently, expect Porsche and Audi to share more components and digital capabilities moving forward. Related Video:

Audi will submit emissions fix for 3.0 TDI V6 to EPA and CARB

Audi will develop a software update for the emissions control system on Volkswagen Group's 3.0 TDI V6 and will submit the changes to the Environmental Protection Agency and California Air Resources Board for approval. If the government regulators accept it, the tweaks could end the emissions problems for an estimated 85,000 of these engines in the US in Audi, Porsche, and VW models. However, the stop-sale still covers these vehicles until further notice. Audi admits in its statement to failing to disclose three "auxiliary emission control devices" on the V6 to regulators, and US law considers one of these systems a defeat device. VW Group offered the engine in the US on the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year. The mill was also available on the VW Touareg and Porsche Cayenne. The EPA filed a violation against the 3.0 TDI on November 2 because the agency reported that the engine's software contained a defeat device to circumvent emissions tests. The regulator recently extended that notice to cover these powerplants in the US from the 2009 to 2016 model years. Audi's statement vaguely estimates the price of this problem to be in the "mid-double-digit millions of euros," and the automaker could face financial punishment by regulators. "Determinations regarding potential penalties and other remedies will be assessed as part of the investigation EPA has opened in conjunction with the US Department of Justice," an EPA spokesperson told Automotive News.

That is the result of the discussions held between a delegation from AUDI AG and the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). The updated software will be installed as soon as it is approved by the authorities. The three brands Audi, Porsche and Volkswagen are affected. Audi estimates that the related expense will be in the mid-double-digit millions of euros.
