The 4Runner is not at all like the Highlander - Toyota's other mass-market SUV. While the Highlander is basically a butched-up Camry family sedan, the 4Runner's a real truck. Which means under that expensive dress, it's wearing loggers' boots. It'll go up-and-down and over-and-through virtually any road or non-road. It may not be quite as adept in a mudhole or a dry creek bed as, say, a Humvee but 4Runner occupants will be whole lot more comfortable.
The new 4Runner is larger than the old one in most key dimensions. It's 5.7 inches (145 mm) longer and 3.0 inches (75 mm) wider with both a 4.5 inches (115 mm) longer wheelbase and a 2.8 inch (70 mm) wider track. At around 4400 lbs (2000 kg), the 4Runner is 600 lbs (270 kg) heavier than the Highlander but about 1500 lbs (650 kg) lighter than its principal North American-based competitors, the GM Envoy/Chevy Trailblazer and the Dodge Durango. Where you'll really notice the weight difference is at the gas pump.
Compared with the last model 4Runner, there's more front and rear legroom, more headroom, and 2 inches (51 mm) more shoulder room and hip room. Five fullsize passengers are easily accommodated.
