What is the Gas mileage of a go kart?

Answer 1

I would like an answer to this as well. I've estimated based on scooters using a 150cc 4 stroke engine as the baseline for comparison. An average scooter will get about 80 mpg. The weight of their frame tends to be about half or less of that of a go-kart (265 lb. vs 550 lb.). Presuming that 2 times the weight equals half the efficiency; then I'm guess-timating a go-kart is at 30 to 40 mpg.

With this engine the scooter can go about 65 mph. The go-kart can go about 45 mph. As I understand it a smaller engine would be slower, but fuel efficiency would increase. It would be good to find a light weight but resilient frame for the body as well.

Anyone else have some ideas or information on this?
