Hi Peter,

Our HiHy receives a mix of city/highway driving and delivers mid-20s mpg using Shell 91 octane. The SUV has been lightly driven recently as most of our miles are logged on the two Prius.

I agree that the HiHy traction control is great on snowy and rainy roads; no complaints. I installed Bridgestone Dueler H/L Alenza tires after 6K miles as I did not like the Goodyear Integrity tires, which were ~40% worn at that point. The Bridgestone tires are on track to deliver about 50K miles of wear.
