How the VW diesels perform in cheat mode

Are you tired of the Volkswagen diesel emissions scandal? Yeah? We are, too. But here's a story that, at the very least, gives us something resembling answers about one of the most important questions surrounding the firestorm – how will the affected cars perform when they're in their emissions-cheating test mode? Consumer Reports was able to find out, tapping into what it believes is the cheat mode. By turning the car to accessory mode, flipping on the hazards, and tapping the gas pedal five times, CR was able to defeat the auto-engaged traction and stability controls, which it believes activates cheat mode. The safeties will reengage if it detects the rear wheels spinning, so the next step was what CR called "a hack." The team unplugged the rear wheel sensors, so the car's computers couldn't tell whether the wheels were spinning. By the way, don't try this at home. With that done, CR hit the road, testing both a 2011 Jetta Sportwagen TDI and a 2015 Jetta TDI sedan in their normal and cheat modes. Why both cars? Well, the 2011 uses the EA188 diesel, which represents the bulk of the affected cars, while the newer Jetta uses the latest EA288, which just arrived for model year 2015. The results are, in a word, interesting. The EA188 engine lost 0.6 seconds on the way to 60 miles per hour while in emissions-compliant cheat mode, and fuel economy fell from 50 miles per gallon to 46. For the newer EA288, the 0-60 difference was negligible – just a tenth of a second – while the fuel economy dipped from 53 to 50 mpg. There are a few takeaways here. First of all, and as suspected, running in cheat mode did hurt both performance and fuel economy. But perhaps more importantly, even in emissions-compliant mode, both vehicles easily beat their EPA fuel economy estimates. According to FuelEconomy.gov, the highest rated 2011 TDI Sportwagen, the manual-trans model, was rated at 30 mpg city and 42 mpg highway, with a combined rating of 34 (the auto drops the city and combined ratings by one mpg, while the highway falls by three). The best a 2015 Jetta TDI sedan can do according to Uncle Sam, meanwhile, is 31 city, 46 highway, and 36 combined with the manual (again, the auto is worse, but only by a single highway mpg).

VW CEO under fire after emissions scandal, stock slide

Pressure piled on the head of Volkswagen on Monday in the wake of an emissions-testing scandal that's seen around 15 billion euros ($16.9 billion) wiped off the company's market value. Following revelations that the German carmaker had rigged US emissions tests for about 500,000 diesel cars, VW CEO Martin Winterkorn apologized Sunday for the fact that his company had "broken the trust of our customers and the public." But saying sorry wasn't enough for investors as they digested the financial and reputational implications of the scandal on the world's biggest carmaker by sales – in mid-afternoon trading in Frankfurt, Volkswagen's share price was down a stunning 17.8 percent at a near three-year low of 132.15 euros. Earlier it had tumbled by more than 20 percent. In the wake of Friday's revelations from the US's Environmental Protection Agency, VW has already halted sales of some vehicles in the US and pledged to cooperate with regulators in an investigation that could, in theory, see the company fined up to $18 billion. Industry analysts said the VW CEO faces difficult questions in the coming days, particularly when the company's board is scheduled to meet Friday. "At the moment, I'd be surprised if Winterkorn can ride this out." - Christian Stadler "At the moment, I'd be surprised if Winterkorn can ride this out, but in Germany there's often a slightly slower process in these matters," said Christian Stadler, a professor of strategic management at Warwick Business School who researches the car industry. Stadler said that if VW were a US company, then the CEO would have gone more or less immediately. In essence, Volkswagen stands accused of skirting the US's clean air rules. The EPA said VW used a device programmed to detect when the cars are undergoing official emissions testing. The software device then turns off the emissions controls during normal driving situations, allowing the cars to emit more than the legal limit of pollutants. Guido Reinking, a German auto expert, said that for a company to engage in such blatant trickery the company's top executives would have to be informed. Winterkorn, an engineer by training, led research and development across the VW group from 2007. He became chairman of the management board the same year. "It's almost impossible to imagine that he didn't know about this special way of programming the engine," Reinking told German television station n-tv.
