The whole uproar about VW's test-tricking program falls into that category. By allowing excess nitrous oxide, VW was able to raise combustion temperature, and save a lot of CO2 emissions and improve mileage. Their numbers were always a big red flag, considering that the system had no scrubber. I think that it was a good trade-off, but we never hear about the benefits they obtained.
However, good mileage is no charm. A weed eater puts out more smog than a car.
