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.

Porsche Panamera gets new diesel in time for Frankfurt

Diesel may not be the first thing that comes to mind when you think of Porsche, but in the European market - that vital one which Porsche calls home - diesels are indispensable. Particularly when you're trying to extend beyond niche sports cars and into the mainstream luxury sedan market as Zuffenhausen has with the Panamera. In fact, diesels account for 15 percent of Panamera sales worldwide (even though they're not offered Stateside), so to keep oil-burning customers happy, Porsche has announced a series of upgrades.
Set to be unveiled in the flesh at the fast-approaching Frankfurt Motor Show, the new Panamera Diesel packs 300 horsepower. That's 50 hp (or 20 percent) more than the model it replaces, significantly dropping the 0-62 sprint from 6.8 seconds to 6 flat, and raising top speed from 152 miles per Autobahn-crunching hour to 161. While they were at it, Porsche's engineers also fitted the rear differential with torque vectoring (previously reserved for gasoline-burning models) and retuned the transmission and suspension.
You can delve into the press release below for all the details - including the new model's improved towing capacity! - but the reality, for better or worse, is that the Panamera Diesel isn't offered here. So if you've been celebrating Labor Day (or even Labour Day, for our friends to the north) like we have, don't go looking for it at your local dealer, who will have only a Cayenne Diesel to show you instead.

Porsche reveals new 911 Turbo Cabriolets, starting from $160,700*

Porsche has come a long way from the days when its entire model line revolved essentially around the 911, but its prototypical rear-engined sports car is still what it's known for best, and still keeps the German automaker pretty busy. With a seemingly endless array of variations on the theme, the 911s just keep on coming until a new generation arrives and then it starts all over again. And what we have here is the new king of the hill (for now, anyway).
Set to debut at the Los Angeles Auto Show a little less than two months from now are the new Porsche 911 Turbo Cabriolets. And no, that's not a typo: that's cabriolets, plural, because what you're looking at are two new models. First up is the 911 Turbo Cabriolet, whose 3.8-liter twin-turbo flat-six develops 520 horsepower, driving the droptop to 60 miles per hour in 3.3 seconds. That's Porsche's claim, and we have a feeling it's a bit conservative. But if that's still not enough, the 911 Turbo S Cabriolet adds an extra 40 hp for a total of 560 to drop the benchmark acceleration run down to 3.1 seconds.
That makes the new topless Turbos 30 horses stronger and 0.2 seconds quicker than the respective models they replace, but the weight penalty involved with replacing a fixed roof with a folding one (and the necessary structural reinforcement) does make the new 911 Turbo Cabs a smidgen more lethargic than their contemporary coupe counterparts, which run the gauntlet in 3.2 and 2.9 seconds in standard Turbo and upgraded Turbo S specs, respectively. They only lose a single tick on the top speed, though, which clocks in at a follicle-tickling 195 mph in either spec. Otherwise the specifications are as identical as you might expect.
