It'll come as a surprise to no one here that lower cruising speeds increase mileage, and this car is no exception. Lowering my speed on the 80MPH limit stretches from 80 to 70-75 took my average from 35 to 39MPG (according to the MFD) for the trip to Idaho.
I'm brainstorming aeromods to try and get a little closer to the Prius' mileage. Rear wheel skirts are first on the list. I'm going to try using 3D printed mounts inspired by the metal ones MetroMPG made
here and coroplast. The current clip design takes about 10 minutes a piece to print and holds onto the car pretty good. My goal is to not make any permanent modifications, like drilling holes.
