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.

Tesla says Model 3 is best-selling midsize premium sedan in America

Auto sales figures are sort of fuzzy numbers, no matter how you slice them and no matter which manufacturer you're talking about. Unless you're specifically tracking vehicle registrations, automakers generally self-report the figures. So, you have to trust that they aren't doing anything too tricky. Plus, not every sale is equal, as some are logged as dealership loaners or demo models, some go to fleets (like to a rental car agency), and still others are, of course, bought by traditional customers looking for a new daily driver. With that preamble out of the way, when we saw a tweet from Tesla claiming that the all-electric Model 3 is the best-selling midsize premium sedan in America, our interest was piqued. According to Tesla, market share of the Model 3 has just surpassed the Mercedes-Benz C-Class, which had up until now led the Audi A4, BMW 3 Series, and Lexus IS as the best-selling sedan in its class. Note that the graph from Tesla below is, we think, specific to four-door models. So, is it true? Judging by the numbers we can find, including some from Bloomberg, which has a running chart to track Model 3 registrations, the answer is... probably. We don't know exactly how many Model 3 sedans Tesla is currently cranking out, but Bloomberg estimates production at about 2,560 units per week, and total sales for 2018 at 34,414. We know the number is increasing regularly, though, and Elon Musk has said most recently production sits around 500 units per day, which, on a seven-day cycle, would be 3,500 per week. We looked up Mercedes' sales figures for the month of May, 2018, and found that the German brand sold 5,419 C-Class models last month, for a total of 23,917 for the year (incidentally, that's down more than 30 percent from the year prior). While the bulk of those sales would surely be made up of sedans, it would also include a small percentage of coupes. Either way, it's likely that Tesla is currently producing and selling more Model 3s than Mercedes is C-Classes. Now, it's also worth considering if the C-Class is the only vehicle from Mercedes that directly competes with the Model 3. We'd guess customers may also cross-shop the CLA sedan with the Tesla, and if that's the case, you might decide it's worth adding in Mercedes' 2,527 CLA-Class sales last month and 9,622 so far for the year. The same argument could be made for certain versions of the BMW 2 and 4 Series.

Audi, Porsche ensnared in new Volkswagen cheating allegations

The scope of the Volkswagen emissions cheating scandal that has enveloped the global automaker for the past six weeks widened Monday. Now, some of the automaker's premium brands are further ensnared in the mess. Officials with the Environmental Protection Agency issued a second notice of violations Monday, accusing Volkswagen of violating the Clean Air Act by using defeat devices that circumvent emissions testing on diesel versions of certain vehicles equipped with 3.0-liter engines. Roughly 10,000 vehicles in the United States contain the illegal software, the EPA alleges. That's a far smaller number than the 482,000 vehicles affected by the first instances of cheating, which Volkswagen confessed to in September. But this latest violation alleges the cheating occurred broadly through the Volkswagen empire and includes vehicles from the Porsche and Audi brands. Audi had one model, the A3, involved in the first round of announced violations. But the brand, which has enjoyed skyrocketing sales in the US in recent years, is more extensively involved in violations announced Monday. The 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5 are among the cars which contain the illegal software, which permits the cars to emit nitrogen oxide at up to nine times the allowable thresholds set in the Clean Air Act, according to the EPA. The 2015 Porsche Cayenne and '14 Volkswagen Toureg SUV are also affected. "There is clear evidence of additional violations and it's important to put Volkswagen on notice and to inform the public." - Janet McCabe. "Audi, which has been on a roll in terms of sales, reputation and image of late, now is being drawn deeper into the quagmire," said Michelle Krebs, senior analyst for Autotrader. "Previously, only the low-volume A3 was under scrutiny, but now Audi's core models are under fire." Audi officials did not respond to a request for comment Monday. In a written statement issued late Monday afternoon, a Porsche spokesperson said, "We are surprised to learn this information. Until this notice, all our information was that the Porsche Cayenne Diesel is fully compliant." Porsche said it would cooperate with authorities.
