2014 Audi RS7 is a 189-mph terror

If you have a burning desire to take yourself and four friends to 189 miles per hour, the 2014 Audi RS7 Sportback can help you out. The luxury hatchback bowed at the 2013 Detroit Auto Show today, complete with a 560-horsepower twin-turbocharged 4.0-liter V8 engine thrashing under the hood. Getting to 62 mph takes a shave under 3.9 seconds thanks in part to the 553 pound-feet of torque on hand from just 1,750 rpm. While the base car comes with an electronically limited top speed of 155 mph, customers can request the governor be removed by purchasing the dynamic package plus, upping the V-max to 189 mph.
Ludicrous? Sure, but Audi says the RS7 can also yield up to 25 mpg on the US scale. With a cylinder-on-demand system, the V8 can deactivate up to four cylinders by closing their valves. Once the driver gets frisky with the throttle, the engine automatically kicks from four-cylinder to eight-cylinder mode in a few hundredths of a second. The engine is bolted to an eight-speed automatic transmission, which pushes power to all four wheels. You can read the full press release below for more information, but we think you'll have a better time viewing our live shots from the show floor..

Audi to lap Hockenheim in driverless RS7

An automaker like Audi will always have a number of different research and development projects going at the same time, and some of them might take on very different approaches. At one end, you'll have its racing programs, and at what you'd assume would be the other, self-driving prototypes. But Ingolstadt is preparing to bridge that gap by running an autonomous prototype at racing speed around the famed Hockenheimring.
Set to take place on Sunday, October 19, during the DTM season finale at Hockenheim, the driverless RS7 will motor at speeds up to 150 miles per hour, right up "to its physical limits with millimeter precision."
Audi anticipates that "the world's sportiest piloted driving car" will run a lap time of just over two minutes, at which the RS7 would stand not only to be the fastest driverless car ever to lap the circuit, but also potentially the fastest four-door - if it can beat the 2:02.71 lap time set by a BMW M3 sedan in 2007.

VW Group exploring F1 options, would likely wait until Ecclestone is out

The real hurdle is that Volkswagen overlord Ferdinand Piech doesn't like Bernie Ecclestone on a personal or professional level. Superbugs. They are antiobiotic-resistant bacteria and viruses, fiends that defy eradication no matter how much counteracting agent you throw at them. Reports that Audi is going to join Formula One? They are the superbugs of rumors; for five years they've been coursing through the blood of motorsport, and no amount of denials or Audi's continued non-presence in F1 has been able to make them go away. Not even a month ago we contracted another bout of it, courtesy of Auto Express, citing sources who said Audi would leave endurance racing and DTM - handing Le Mans over to Porsche, instead of the other way around - and buy either Red Bull or Toro Rosso for an entry in 2016 with an in-house powerplant. Within 24 hours of that story, Audi Sport sent the tweet, "Audi in F1? There rumors keep appearing with regularity since years. It's pure speculation again this time and without any foundation." Now, few things are impossible in F1, but lining up on the grid in 2016 is not far away from needing to be ready tomorrow, in F1 terms, which is why these announcements come long in advance. Honda, you'll recall, gave us almost two years' notice of its F1 reunion and Porsche gave us three years notice about Le Mans. A brand-new report in the BBC says that Audi is using new hire and ex-Ferrari technical director Stefano Domenicali to lead a feasibility study into an F1 program. According to that story, the real hurdle to the foray, however, is that Volkswagen Group overlord Ferdinand Piech doesn't like F1 boss Bernie Ecclestone on a personal or professional level, so one of them would need to leave his position before Audi could say yes, feasibility be damned. Since we're talking about two men who define professional longevity, that day might not come soon. The BBC story goes on to say that Martin Winterkorn, head of the VW Group management board, would like to see the group in F1, and that if it happened it would be with a "car designed and made in Germany." Ladies and gentlemen, you know where to file this one...
