2024 Toyota Tacoma X-Runner concept unveils 421-hp Tundra twin-turbo 3.4L V-6 power

Toyota revived the iconic X-Runner label for their latest creation, the 2024 Tacoma sport-truck concept, infusing it with a boosted suspension and increased power, alongside other enhancements. This iteration of the Tacoma X-Runner concept boasts a robust twin-turbocharged 3.4-liter V-6 engine, a close relative of the Tundra’s.

Generating a staggering 421 horsepower and 479 pound-feet of torque, this engine surpasses the potency of the 2024 Tacoma’s primary configuration—a 326-hp four-cylinder hybrid. Torque distribution to the rear wheels is handled by a robust Tundra-inspired solid axle equipped with a 4.30:1 final drive and an electronic locking differential.

In terms of design, the exhaust pipe has been redirected to sit just below the truck’s rocker panel. Beneath the revamped exterior, the Tundra’s air suspension has been seamlessly integrated, allowing the Tacoma to maintain a lower profile while still accommodating heavy loads.

The engineering team’s dedication was evident in their adjustments to the length of the control arms, ensuring they aligned perfectly with the Tacoma’s lowered stance. In addition, Toyota enhanced the car’s stability by reinforcing the frame and expanding its track width by approximately three inches.

To further refine the driving experience, the suspension has been fortified with stiffer springs and each corner is outfitted with 2.5-inch Bilstein shocks. Complementing the ensemble are Lacks Enterprises’ 21-inch carbon-fiber wheels, featuring forged aluminum centers, all outfitted with Michelin 285/45R21 Sport Tires.
