a little slower

A few years ago, one of the magazines hyper-miled a Porsche 911 GT3.
It was rated EPA 19 mpg highway. They periodically saw over 32-mpg, and predicted that with the optional touring fuel tank that, they'd be able to do 650- miles on a tank.
Driving 50-mph was part of their strategy.
