On the topic of fuel consumption, I was disappointed in the new Toyota Corolla I had as a rental for a day. It had all the on-board computer functions of a BMW (!) including instant fuel consumption. It's surprisingly thirsty even with my delicate throttle inputs. I only averaged 31,4mpg (7,5l /100km) on mostly highway drives and no excessive speeds. I think the over-sensitive throttle calibration has something to do with this.
