The main goal of Quattro Ultra is to reduce fuel consumption, something Audi claims it has proven — and not just in a controlled environment. According to the automaker, internal testing in live traffic scenarios in Germany found an average fuel consumption improvement of a little less than one mpg (0.3 L/100 km) compared to the same vehicle without Quattro Ultra. That may not seem like much, and probably benefits Audi’s emissions targets more than the average consumer, but every little bit helps. Crunching the numbers using the U.S. EPA’s fuel economy rating model, driving 15,000 miles annually would result in about two tanks worth of gas saved over the course of a year.
