Toyota 4Runner
History of the Toyota 4Runner
The Toyota 4Runner started in 1984 as a rugged SUV based on the Toyota pickup, featuring a removable top. Over six generations, it evolved from a basic off-road truck to a versatile mid-size SUV. The 6th generation, introduced in 2025, continues the 4Runner’s legacy with updated features and modern technology while maintaining its strong off-road capability.

Expanding the Toyota Family: The 2025 4Runner release marks our first foray into the current Toyota trucks lineup—but not the last.
