For the all-wheel drive variant of the IS 250, the EPA estimates 20 mpg in the city, 28 mpg on the highway, and 23 mpg combined. The slight decrease in fuel efficiency is due to the added weight and drivetrain components of the all-wheel drive system.

  • Driving Style: Smooth, moderate acceleration and maintaining a consistent speed can improve the vehicle's miles per gallon.
