Audi confirms autonomous tech for next-gen A8

Like so many of its rivals, Audi is hard at work getting its autonomous driving technology up to speed and ready to reach the market. And now it's revealed when we can expect that time to come – or at least in what form it will arrive. In announcing the achievements of its latest RS7 Piloted Driving prototype, Audi has confirmed that the system will be offered for the first time on the next A8, the upcoming iteration of the German automaker's flagship sedan. Just as we heard this past January, the next-gen A8 will be able to drive itself around town at speeds of up to 37 miles per hour. Ingolstadt still isn't saying when we can expect the new A8 to arrive, but considering that the current model has been around since 2009 (albeit with periodic updates along the way) and that its key rivals – the Mercedes S-Class and BMW 7 Series – are both much newer models, Audi shouldn't be waiting much longer to launch its new flagship. The announcement was made as part of the reveal for "Robby," the latest version of the company's self-driving RS7 concept. The previous version, dubbed "Bobby," was based on the same model, and gave our man Jonathon Buckley over at Translogic a run for his money around Ascari a few months ago. (We'll let you watch the video below to see who fared better). But the new version is a good 882 pounds lighter, lapping the Sonoma Raceway (previously known as Infineon or Sears Point) in 2:01.01. That's in what is ostensibly still a road car, just one that's operated by a computer. The fastest lap ever recorded on the full 2.5-mile circuit, in case you were wondering, was also achieved in an Audi, but that was the R8 Le Mans Prototype that Allan McNish hustled around in a 1:20.68 qualifying lap.

On one of the world's most challenging race tracks, the Sonoma Raceway in California, the latest generation of the Audi RS 7 piloted driving concept has surpassed previous top performances once again. Audi will be offering piloted driving for the first time in the upcoming generation of the Audi A8.

Audi A7 Sportback H-Tron Quattro packs plug-in hydrogen powertrain

If you think a plug-in diesel hybrid is an expensive proposition, just wait until you hear details about the just-revealed Audi A7 Sportback H-Tron Quattro. The "H" in H-Tron, as you might guess, stands for hydrogen, so say hello to a new concept that combines a plug-in battery system with a hydrogen fuel cell. Yeah, exactly. Let's start with the numbers. On the plug-in side, the new H-Tron has an 8.8-kWh lithium-ion battery that can power the car for up to 31 miles on battery power. With electric motors on both axles – it's a Quattro, after all, but a through-the-road hybrid with electronic torque distribution management – the A7 H-Tron uses a hydrogen fuel cell and four (!) H2 tanks to offer about 62 miles per gallon equivalent. Audi says the overall fuel cell stack efficiency is "as high as 60 percent" while the electric motors operate at 95 percent efficiency. Efficiently turning all of that electricity into movement means the A7 Sportback H-Tron Quattro has a total power output of 398.3 pound-feet of torque. The 4,299-pound concept can allegedly go from 0-62 miles per hour in 7.9 seconds and has a top speed of 112 mph. The car's total range is 311 miles. The A7 H-Tron is not the first plug-in hydrogen vehicle concept. That title goes to the Ford HySeries Edge. Mazda also considered putting a hydrogen range extender in the Mazda5 plug-in van. The Audi A7 Sportback h-tron quattro It sprints from 0 to 100 km/h (62.1 mi) in 7.9 seconds and on to a top speed of 180 km/h (111.8 mph). It covers over 500 kilometers (310.7 mi) on one tank of fuel – and its exhaust emits nothing more than a few drops of water: The A7 Sportback h-tron quattro, which Audi is unveiling at the Los Angeles Auto Show 2014, uses a powerful, sporty electric drive with a fuel cell as its energy source that operates in combination with a hybrid battery and an additional electric motor in the rear. The overall electrical system power of 170 kW is transferred to both the front and the rear wheels. This drive configuration makes the emission-free Audi A7 Sportback* a quattro through and through – a new departure in fuel cell cars. "The A7 Sportback h-tron quattro is a genuine Audi – at once sporty and efficient. Conceived as an e-quattro, its two electric motors drive all four wheels," explained Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "The h-tron concept car shows that we have mastered fuel cell technology.

VW stock plummets as Euro markets open

The fallout from Volkswagen's installation of an emissions "defeat device" on nearly 500,000 diesel-fueled models in the US is already hitting the automaker hard on the German stock exchange. At one point, the share price plummeted 23 percent to erase the equivalent of $17.6 billion in value. Things eventually bounced back slightly to a still severe 19.23 percent loss, according to Bloomberg as of this writing. The scandal couldn't come at a worse time for chairman Martin Winterkorn. The VW supervisory board takes up the issue of renewing his contract on September 25, Bloomberg reports. If things get bad enough, the door could be open for a new boss to step in. Dealers in the US might start feeling the pain from this, as well. Affected 2015 VWs that are still at showrooms are now under a stop sale. Until the issue is straightened out, the Environmental Protection Agency isn't certifying the company's 2016 diesel models with the 2.0 TDI, either. The diesel emissions problem was first discovered by research from West Virginia University and the International Council on Clean Transportation. In some cases, the engines can produce 40 times more nitrogen oxides than allowed. The automaker could be on the hook for $18 billion in fines for the breach, but the actual figure is expected to be lower. In response, Winterkorn has issued a public apology and ordered an independent investigation into what happened. The EPA and California Air Resources Board have also been looking into the situation. This could become an international problem, though. According to The Detroit News, European authorities might begin similar inquires to check the automaker's diesel emissions there.
