VW confirms Audi's emissions test transmission anomalies

Just a week after reports that the California Air Resources Board (CARB) found an emissions cheat in some Audi automatic transmission software programs, parent company Volkswagen has come clean. As reported by Reuters, VW's response to an article by Munich's Sueddeutsche Zeitung stated that the adaptive shift functionality can "lead to incorrect and non-reproducible results." Adaptive shift programs alter the characteristics of a vehicle's transmission to suit different driving styles. Gentle driving will result in earlier shifts and lower engine revs, while hard-charging on the pedals and steering will make the transmission more responsive and hold gears longer. That adaptation can change over time or even on a short-term basis. And it can save fuel. The difference in this case is that is seems that the Audi transmissions were specifically programmed to detect emissions test conditions. As we explained in a previous article, one of those test conditions is keeping the wheel straight. Turning more than 15 degrees shuts the test mode off. According to Reuters, the US government is trying to determine whether this classifies as an emissions cheat device, although VW, Audi, and the EPA have not commented on the record. This latest accusation is separate from the larger VW diesel emissions scandal. Related Video: Image Credit: Getty Editorial Government/Legal Green Audi Volkswagen Emissions vw diesel scandal

Stanford goes from Pikes Peak to Thunderhill with autonomous Audi TTS

In the years since Stanford University engineers successfully programmed an Audi TTS to autonomously ascend Pikes Peak, the technology behind driverless cars has progressed leaps and bounds. Back then the Audi needed 27 minutes to make it up the 12.42-mile course – about 10 minutes slower than a human driver. These days, further improvements allow the vehicle to lap a track faster than a human. The researchers recently took their autonomous TTS named Shelley to the undulating Thunderhill Raceway Park, and let it go on track without anyone inside. The Audi reportedly hit over 120 miles per hour, and according to The Telegraph, the circuit's CEO, who's also an amateur racing driver, took some laps as well and was 0.4 seconds slower than the computer. To make these massive technological advancements, the Stanford engineers have been studying how racers handle a car. They also hooked up drivers' brains to electrodes and found the mind wasn't doing as much cognitively as expected. It instead operated largely on muscle memory. "So by looking at race car drivers we are actually looking at the same mathematical problem that we use for safety on the highways. We've got the point of being fairly comparable to an expert driver in terms of our ability to drive around the track," Professor Chris Gerdes, director of Stanford's Revs Program, said to The Telegraph. With progress coming so rapidly, it seems possible for autonomous racecars to best even elite drivers at some point in the near future. Related Video:

2017 Audi A5 First Drive

It might not look it, but behind the 2017 Audi A5's evolutionary styling update there's a new platform and a host of mechanical and technological upgrades that make it the most advanced offering in its class. We got to sample the new A5 on the windy roads outside of Porto, Portugal, which gave us an in-depth look at the car underneath the unremarkable exterior. The A5 may no longer be the haute couture choice in this segment Í­– that title goes to the Mercedes-Benz C-Class Coupe – but there isn't a bad line on the new car, and it's more creased and toned than before. Given the bulging hood and chunky C-pillar, we'd say its gym membership is paying off. This might look more like a mid-cycle update, but what's underneath is new: a scalable architecture known internally at VW Group as MLB Evo, an optional seven-speed dual-clutch gearbox, and the third-generation EA888 2.0-liter, four-cylinder turbocharged gasoline engine. This engine debuted in the A6 and is rated at 252 horsepower and 273 pound-feet of torque. That's a healthy 32 hp and 15 lb-ft more than the 2016 A5's 2.0-liter offered, and it showed on our spirited drive through Portugal's grape-growing region. A handful of A5s will leave the factory with six-speed manuals, but most buyers will find a new seven-speed dual-clutch transmission in place of last year's eight-speed conventional automatic. Audi worked hard to improve initial throttle response to eliminate the clunkiness endemic to torque-converter-free transmissions. In urban slogging, the gearbox does a very convincing impression of a traditional automatic. In sport mode, the transmission livens up and delivers the rapid-fire shifts we expect from this type of gearbox. We did not have the opportunity to sample the stick. Our test car had Audi's Euro-spec version of this engine, which utilizes both direct and port fuel injection. American models will forgo the latter. Brisk acceleration is matched by a subtle growl piped in from under the hood at higher rpm – about the only noise you'll hear. The A5 is astonishingly quiet. In fact, it was that quietness that encouraged us to leave the coupe in the Drive Select's comfort setting for much of our drive. Drive Select tweaks the car's steering, throttle response, and, on cars so equipped, the optional adaptive suspension. Truth be told, Comfort rides a little too plush and Dynamic a little too firm.
