Up to 45 mpg hwy, 35 city. If you drive it like a maniac, you'll get poor mileage like any other car. If you drive more conservatively, you'll get better mileage like any other car, it's all relative. Overall, we're getting about 30 mpg, mostly city, but I can go more than 600 miles on a 17- gallon tank on pure hwy miles. In cold weather it does take a few miles for the electric motor to warm up. Very comfortable and reliable.
