6th Gen 4Runner Fuel Economy Test: Turbo Engine Efficiency & Air Dam Impact

In this episode, The Fast Lane Car takes the new sixth-generation 4Runner for a spin to test its real-world fuel economy, focusing on the impact of the front air dam. With the new 2.4 L turbocharged engine replacing the old V6, efficiency and performance are under the microscope. The team employs the TFL 2-click method to fill up the tank and hits the highway for a cruise at 65-75 mph, using cruise control for consistency. They start without the air dam, achieving 22.3 MPG, and then reattach it to see a slight improvement to 23.47%, just shy of expectations.

As they delve into the engine's capabilities, the team discusses the benefits of the turbocharged setup with an 8-speed transmission, offering better low-end torque and passing power. The 4Runner's TRD Offroad Premium trim, equipped with off-road tires and suspension, adds a rugged touch to the test. Despite the hefty price tag of $58,000 for the model tested, the 4Runner impresses with its refined ride and advanced features, including adaptive cruise control and a premium audio system. The Fast Lane Car recommends checking out the 4Runner 6G Forum for insider insights and updates on modifications.

The comparison with the new Toyota Tundra's fuel economy sparks a debate on the 4Runner's performance, with viewers invited to share their thoughts in the comments section. The team wraps up the test at the pump, revealing the results and reflecting on the 4Runner's efficiency journey. With Gavin behind the camera, they sign off, leaving viewers eager for the next adventure.
