You might misunderstand what VW did. Apparently it is common for cars to have a "test mode" bit, because they run on a dyno (only one set of wheels spin), and the car may disable certain traction control systems, etc. VW changed the way other systems (the engine itself) function in this mode. So even if everything is exactly the same on the road (e.g. 30mph in a straight line for hours), the car will perform differently and have different emissions. You don't drive around on a dyno. Optimizing for the test may go up to the line, but VW crossed it. |
