First introduced as a pickup truck-based compact SUV in 1982, the Toyota 4Runner grew to become one of the world’s most popular rugged mid-size SUVs. 4Runners typically deliver highway gas mileage figures in the 20 mile per gallon (MPG) range. Some of the earliest four-cylinder trucks were the most fuel efficient of the bunch, with highway gas mileage ratings in the mid-twenties.
The 2008 4Runner is available with a 4.0 liter six or a 4.7 liter V-8. (The V-8 equipped 4WD version can be thirsty.) The 4Runner was last redesigned for the 2003 model year.
