Test Driver Ratings & Comments

Acceleration commentsAll testing conducted in 2WD High. A little reluctant to get away from the line, but once under way, the 4Runner's V6 engine is obviously powerful. Best results were with zero wheelspin in Sport mode with automatic upshifts. This performance is impressive considering the vehicle's obvious off-road engineering and considerable weight.
Braking ratingAverage
Braking commentsConsidering the true off-road tuning of the 4Runner plus the tall-sidewall off-road tires and compliant, long-travel suspension, a consistent ability to come to a halt in 140 feet is remarkable. Consider the comparison with the Hummer H3!
Handling ratingAverage
Handling commentsSkid pad: Isolated steering feel, pronounced body roll and off-road tires -- evidence of off-road tuning -- yet consistent 0.71g. Pretty good. Very little intrusion from stability control when engaged, hence very similar performance. Slalom: The stability control is calibrated to intrude exactly at the limit of grip, so near identical results with system engaged or disengaged. As you'd expect from tall tire sidewalls and soft suspension, the 4Runner is loath to change direction quickly, so it takes an eternity to respond to steering input.
