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.

2016 Audi A4 is larger, lighter [w/video]

The 2016 Audi A4 arrives with a bang, but no surprises. We say that because the formula for creating the new A4 is one we know all too well. Make it larger, add a bunch of content, reduce weight, and improve both power and efficiency. It's a recipe for success, and this fifth-generation A4 looks to be a solid contender against its chief rivals, the BMW 3 Series and Mercedes-Benz C-Class. The shape hasn't changed; it's immediately recognizable as an A4. Instead, this new model updates that familiar design with sharper lines, similar to what we've seen on the new Q7, or even the R8. The big story here is that the 2016 A4 is up to 264 pounds lighter than its predecessor, depending on trim and engine. Additionally, the A4 is the most aerodynamic car in its class, boasting a drag coefficient of just 0.23. A fresh, modern cabin lies within that lighter shell – one that looks decidedly more upscale than the last A4. Many elements are reminiscent of the Audi Prologue concept that we first saw (and drove) in Los Angeles last year – specifically, the steering wheel, and the new MMI controls. In fact, Audi has positioned its infotainment controls closer to the center console – in front of the gear selector. This reminds us of the current A8, where Audi specifically designed its shifter to act as a sort of wrist rest. You can rest your arm on the gear lever and still access all of the MMI functionality. Speaking of which, that's the latest generation of Audi's MMI interface, packing navigation, touch capability, LTE connectivity, and WiFi in the 8.3-inch color display. Audi isn't saying which engines will come to the United States right now, but when the new A4 launches, it'll be offered with three gasoline and four diesel engines in Europe. Our best guess is that the US-spec car will come with the latest 2.0-liter TSFI turbocharged inline-four with 272 horsepower, as well as Audi's tried-and-true 2.0-liter TDI diesel four. Front- and all-wheel drive will be available, and for the first time, two-wheel-drive models will get a proper dual-clutch transmission – no more CVT. There's a whole lot more to lean about the A4 in the press release, posted after the reveal video. You can also see the 2016 A4 in sedan and Avant forms in the galleries above and below – it's unclear if the wagon will make its way to the US. The A4 Avant has been sold here before, but currently, Audi only offers that more functional bodystyle in Allroad spec.

With increased range, Audi R8 E-Tron revving up for production. Maybe

As Tesla Motors proved mightily in 2013, an expensive EV with a long range can sell quite nicely, thank you very much. Perhaps Audi was taking notes, since its all-electric R8 E-Tron's on-again/off-again odyssey appears to be on again, according to UK's Autocar, citing Audi's Urlich Hackenburg. The model is near the approval stage for production, and the key to the green-light is the fact that its single-charge range has been almost doubled to 250 miles. The R8 E-Tron gained kudos in these parts last June by turning in a rather brisk 8:09 time around Germany's Nurburgring track, a record for a production electric vehicle (check out the really quiet video here). Still, plans for the 376-horsepower model, which has two electric motors and was first shown off at the Frankfurt Auto Show in 2009, had been put on the proverbial blocks largely because of a relatively short single-charge range of about 150 miles. Then word came out last spring that Audi would produce maybe 10 units before reports from Australia's Drive late last year indicated that plans for potentially broader production were being resuscitated.
