Question

What mpg should I get with toyota Prius driving 69 mph on hilly freeway?

Answer 1

About 45 mpg if you are on cruise control.

Keep it at 55-60 mph and you should get close to 50 mpg (as long as you are not going into a strong headwind).  

Answer 2

I drive my prius up north all the time on I-75 and it will use gas/electric up hills and it switches between gas and gas/electric on flat highway. And it get 49 mpg. The average on my prius is 62 mpg.

Answer 3

probably in low 40mpg. Highway and hill make Prius use gas instead of electric motor.
