The Toyota 4Runner enters the 2010 model year with a variety of fuel economy choices based on the driver's needs. The base engine on the 4Runner is a 2.7 liter four cylinder that produces one hundred fifty-nine horsepower and one hundred eighty pound feet of torque. The powerplant's fuel injection system is an electronic fuel induction design, and the powerplant also features a dual overhead cam valvetrain and four valves per cylinder. The four cylinder engine can only be ordered with a two wheel drive system. The four cylinder returns twenty miles per gallon in the city, and twenty-six miles per gallon on the highway. The optional engine in the 4Runner is a 4.0 liter six cylinder dual overhead cam unit. The engine can be ordered with either a two wheel or four wheel drive system, and an automatic five speed transmission is the only transmission available
. The 2.7 liter six cylinder has an output of two hundred seventy horsepower at five thousand six hundred revolutions per minute; the torque rating for the 4Runner is two hundred seventy-eight pound feet at four thousand four hundred revolutions per minute. Fuel economy ratings for the six cylinder 4Runner with the two wheel drive system are seventeen miles per gallon in city driving and twenty-three miles per gallon in highway driving. With the four wheel drive system, the fuel economy rating is the same for city driving but drops to twenty-two miles per gallon on the highway. The six cylinder-equipped 4Runner can tow up to five thousand pounds when properly equipped, but towing anything with the 4Runner will lessen its fuel economy ratings.
