Holy Gas Gobbler. You know there are positions on the throttle between idle and WOT?
Why would you buy a car with a rear suspension designed solely for straight-line acceleration and a 420hp engine... and not savor that beautiful torque curve?
You have to pay (at the pump) to play.
Best I've gotten so far is 18.2mpg around town. On the highway I nearly hit 22mpg, averaging 80-85 on a trip to Nashville, with a lot of time spent at WOT coming back onto the highway's on-ramps, and rolling back up to speed after waiting behind a semi trailer struggling to pass.
The beauty of the Coyote motor is having to *decelerate* as you merge into freeway traffic at the end of that on-ramp, and not struggling up to speed in your 4 banger econobox. Just my humble opinion.
