What engine comes in a Toyota 4Runner?

The current Toyota 4Runner in the U.S. market is powered by a 4.0-liter V6 gasoline engine. There are no turbocharged four-cylinder options in the latest models; Toyota continues to offer the same V6 across the lineup, paired with a traditional off-road-ready drivetrain.


In depth, the 4.0-liter V6 (engine code 1GR-FE) delivers solid low- and mid-range torque for off-road and highway driving. It uses dual overhead cams, 24 valves, and VVT-i to optimize performance across revs. The engine is paired with a 5-speed automatic transmission and a part-time four-wheel-drive system with a two-speed transfer case on most trims, supporting low-range crawling and off-road modes.
