Estimates suggest that emissions on the road could have been 40 times worse than in the testing environment.
A new notice posted this morning on the EPA's Web site and sent to Volkswagen includes vehicles using the larger 3-liter V-6 TDI engine. The notice lists those vehicles as the "VW Touareg," "Porsche Cayenne," "Audi A6 Quattro, A7 Quattro, A8, A8L, and Q5."
You need to partially blame the testers too because they work with a defined setup that can be easily detected. It's a simple rule to carry out your tests under real-life conditions, and in case of a car that means to drive it; but it is just too convenient not having to do that and create an exploitable scenario.
