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.

Watch this Audi RS6 go 208 mph... on ice

In and effort to promote the high-speed grip of its new Hakkapeliitta 8 winter tire, Nokian threw a set of its new rubber on a race-prepped Audi RS6 and got moving - very, very quickly. In fact, on March 9 on top of the very frozen Gulf of Bothinia near Oulu, Finland, Nokian's test driver Janne Laitinen set a new world record for the fastest speed recorded driving on ice. If you'll recall, this isn't the first time that Audi and Nokian have played this game, either.
Using the guidelines set forth by the Guinness Book of World Records for such things, Laitinen averaged 208.602 miles per hour (335.713 kilometers per hour) over the course of two runs on natural, untreated ice. Another constraint is that the ice speed record must be done using commercial available tires, which is obviously great PR for the new Hakkapeliitas. The press release doesn't make any mention of how the RS6 was prepared to reach such high velocities, but the images of the car make it clear that this is no stock machine. Scroll on below to see the impressive video evidence of the Audi's record run.

Mercedes chief invites Audi, BMW to compete in F1

Mercedes-Benz didn't just win the Formula One World Championship in 2014 – it positively dominated it. The team won all but three of the grands prix this season, scoring a one-two finish at more than half of them and landing at least one car on the podium at every race without exception. It goes without saying, then, that the German automaker thrives on competition, but now it's welcoming even more. Speaking with Germany's Sport Bild at its homecoming celebration in Stuttgart, Daimler chief Dieter Zetsche welcomed Mercedes' biggest rivals Audi and BMW to join it on the F1 grid. Noting that the three German brands share some 80 percent of the market for luxury automobiles, Zetsche said that F1 would make a natural arena of competition for Mercedes, Audi and BMW to fight for top bragging rights. The three currently compete against each other in front of home audiences in the DTM touring car series – effectively Germany's equivalent to NASCAR – but of the ten races held this year, the majority were in Germany itself, and all of them took place in Europe. BMW last competed in F1 when it bought the Sauber team in 2006, but withdrew from the series in 2009. Despite its progenitor Auto Union having fielded the famous Silver Arrows in pre-war grand prix racing, Audi has never been a player in modern F1 racing, though recent rumors have linked it to a potential foray – spurred by the arrival of sister-company Porsche on its home turf at Le Mans, the departure of several of its key endurance drivers and the hiring of former Scuderia Ferrari chief Stefano Domenicali. Porsche had similarly considered an F1 program before getting the go-ahead to compete with Audi at Le Mans. As for the prospect of Mercedes competing in other international racing series, Zetsche added that year-long preparations for 24 hours of racing at Le Mans didn't present a good cost-benefit ratio in his estimation, but that Formula E (where Audi currently supports a quasi-works entry) would be worth a closer look.
