The Toyota 4Runner, the fifth generation of this rugged, full-capability SUV and a key model in the Toyota SUV lineup for 28 years, continues as one of the few fully capability SUVs available in its segment. The 4Runner combines rugged body-on-frame construction with suspension technology that yields ride comfort more often associated with car-based platforms. The 2013 4Runner is available in a variety of configurations and in three models: a well-equipped SR5, top-of-the-line Limited, plus a Trail grade for maximum off-road capability. Optional third-row seats allow for up to seven-person capacity. Drivetrain configurations include rear wheel 4x2, part-time 4x4 and full-time multi-mode 4x4 with a locking center differential. All models are equipped with a 4.0-liter, 270-horsepower V6 teamed to a five-speed ECT-i automatic transmission. For 2013, the SR5 grade gets a switch-type control for the transfer case, replacing the lever.
