The 4Runner is no car-based crossover station wagon. It's built on a rugged ladder frame with a solid rear axle. While some consider this design dated when compared to the latest SUVs or CUVs, which use unit body construction and independent rear suspensions, the 4Runner's more traditional design offers better recreational capability and long-term durability.

Yet the 4Runner does not ride like a buckboard wagon. Toyota engineers went to great pains to prove that this durable, adventurous configuration need not compromise everyday comfort and convenience. The 4Runner is quite comfortable around town and on the highway, with a nice ride quality, almost luxurious. An optional linked shock-absorber system called X-REAS further improves handling in sweeping, high-speed turns. Active safety features include ABS, EBD, Brake Assist, traction control, and electronic stability control, all standard.
