The Audi R8 doesn't need turbos to visit Jay Leno's Garage

When Audi launched the original R8 in 2006, it caused a sensation. For its second go at the model, Audi skipped the V8 and went straight for ten-cylinder power in two states of tune: the V10 and the V10 Plus. Of course Jay Leno had the more potent of the two visit his garage. In V10 Plus trim, the Audi makes over 600 horsepower – all from a naturally-aspirated V10 in a segment increasingly dominated by turbocharging. Rivals like the Mercedes-AMG GT, Porsche 911 Turbo, McLaren 570S, and Ferrari 488 have all adopted turbochargers, which makes the R8 something of a modern-day Shelby Cobra, as Leno puts it. See what else he has to say in the video above – and don't forget to watch to the end to see how the launch control works.

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.
