This is the closest you're going to get to a hybrid, without an electric or diesel motor. Right now I'm averaging about 36 mpg with aggressive 60/40 city/hwy driving. And get over 40 mpg hwy. It's an amazing car, with the room and comfort of some mid-sized vehicles. I also drive a Tacoma, and have found the Yaris more comfortable. Contrary to other posts, I have found my Yaris auto to be quite peppy. It won't set speed records, but it's very practical. I got a feeling that this will be a keeper for a long time to come.
Gas mileage; deceptive roominess; and maneuverability in the city.
I would like to see it in a diesel. Getting 40 mpg now, could you imagine what a diesel would give you?
