you could drive it painfully and get 40-45 mpg from the zed on motorway driving, cruise on at around 50mph in 6th on a nice day but theres no fun in that, i average 29-32mpg between city and motorway, although ive seen it drop to 13mpg and had it at 58mpg (for a couple miles) just to see how economical it could be if i really tried, anything higher than 18mpg in a sports car and im happy,
