| Year | Body/Powertrain | Comment |
| 2011 | 4dr SUV 270-horsepower 4.0L V6 5-speed shiftable automatic 4WD, part-time w/low range |
Not wide enough for circumferentially challenged bodies. Bottom cushion too narrow, confined bolsters, not long enough under thighs. see full Toyota 4Runner review |
