The 2023 Toyota 4Runner has big shoes to fill. The current 4Runner continues to sell incredibly well in spite of its thirsty 4.0-liter V6 and somewhat dated design. As such, we don’t expect Toyota to take too many risks on the new 4Runner, although a hybrid powertrain is a certainty, at least as an option. It could be based on a new modular architecture, shared with the next-generation Tundra (spied testing above), Tacoma, and Sequoia.
