Porsche accused of using steering inputs to cheat on emissions tests

Last week, the German transport authority KBA announced it was investigating Porsche and Audi for cheating on emissions tests. Wirtschaftswoche, a German economic publication, says the KBA's investigation focuses on a system that uses steering inputs to determine whether or not the car is being tested. While Audi has recalled 24,000 models, Automotive News reports that currently Porsche denies any wrongdoing. According to KBA, if the affected cars measured a steering input of 15 degrees or more, they would emit excess nitrogen oxide emissions. It's important to note that this is different than Volkswagen diesel CO2 emissions. The cars broke European strict emissions standards, so it's unclear what impact this has on cars in the US. Audi has recalled the A7 and A8, though it's unclear which Porsche models the KBA is investigating. Fifteen degrees is a small amount of steering input. The wheel can move that much just to move around a pothole or bump in the road. Essentially, if you're driving, you're moving the wheel at least 15 degrees in one direction or the other. If these allegations turn out to be true, it's going to be another blow to Volkswagen, Audi, and Porsche. While public trust in Volkswagen is supremely low, for the most part, Porsche's image has remained fairly clean. NOx emissions don't have as big of a long-term effect as CO2, though they're still bad for humans.

Audi Q7 plug-in hybrid spied, Porsche powertrain possible

It's no secret that a new Audi Q7 is on the way. The replacement for the aging, three-row luxury CUV has already been spotted once, in December of 2013. Now, though, we have images of the second-generation model lapping Germany's Nürburgring Nordschleife, and it just happens to be showing a feature we reported on at the end of July - a plug-in-hybrid powertrain.
Given away by its high-voltage stickers on the window and a spare door to hide the charger - note how both the driver and passenger sides sport an access point - our spies snapped a series of photos, and put forth the compelling idea that the new Q7 would use the PHV system from the Porsche Cayenne S E-Hybrid.
If that's the case, that should mean at least 320 horsepower from a 3.0-liter, supercharged V6, while an electric motor chips in a further 95 ponies for a total system output of 416 hp.

Audi Quattro concept production hopes still alive, could be more radical

Remember the gestation period of the Lexus LFA, the one that, in automotive time, took so long that its origins could have been carbon dated? We feel like it's deja vu all over again, as Yogi Berra would have said, this time featuring the Audi Quattro and Audi Sport Quattro. It was 2010 when our cameras first glimpsed the Audi Quattro Concept (pictured right) at the Paris Motor Show, and we tasted its turbocharged 2.5-liter, five-cylinder powerplant not long after. Last year we met the hybrid, 700-horsepower Audi Sport Quattro concept at the Frankfurt Motor Show, but we got no closer to finding out if there'd ever be a version we could buy. A report in Autocar keeps the flame of hope burning, quoting Audi design chief Marc Lichte at the LA Auto Show saying, "We are working on Quattro, it is still alive." Lichte went on to say, however, that the next imagining is "more extreme" than those we've seen, and, "There will be surprises." Those words alone are a surprise. The last we heard about the Quattro revival was Audi boss Ulrich Hackenberg saying he wanted a more accessible homage to the original, and we don't know how "more extreme" jives with that. Seeing that Audi is serious about the idea, at least, we shouldn't have to wait long to find out. Just don't get your hopes up about its affordability yet.
