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

Audi stealthily tests RS4 Avant

With S3s, R8s and RS7s aplenty, Audi offers no shortage of performance models in North America. But one of our favorites is always kept just out of arm's reach. That of course is the RS4 Avant, and here we see Audi Quattro GmbH testing the latest version. Though it may look like a plain old S4 – and even wear S4 badges – the wider fenders and bigger wheels suggest that this is in fact a prototype for the upcoming RS4 Avant. For those unfamiliar, that nameplate connotes the best of all worlds within the A4 range: maximum power, maximum traction, and maximum luggage space. All the ingredients, in short, to make us wonder why anyone would rather drive a crossover. After the first-gen RS4 employed a twin-turbo V6, the subsequent two generations went with a 4.2-liter V8. This model, however, could adopt an electric turbocharger setup to give it all the power it needs (and then some) with a new form of hybrid setup that will soon be spreading across the industry. The bigger question on our mind, of course, is whether the new performance wagon will make the transatlantic voyage to North American showrooms. We're holding out hope that Ingolstadt may make a real run down American roads at the likes of the Mercedes-AMG C63 and BMW M3. Whether it brings the wagon body-style along with it is another matter entirely, but we can always dream. Related Video:
