Back in June, Toyota first showed the world this wild-child Sienna, which it dubbed Ultimate Utility Vehicle. Since then, the former minivan turned beastly off-roader has been touring the country as part of the company’s Ever-Better Expedition, sort of a team-building exercise. Now it’s pulling in to SEMA—its natural home, one might argue—and we’re finally learning more about its build.
We already knew that this sinister Sienna sits atop the chassis of a Toyota Tacoma pickup. Obviously, the nerdy sliding doors are replaced by motorized side doors. The fronts have been converted to suicide doors. The matte-black body is nearly all custom, including the front fenders and all four doors. The unique front bumper is by the folks at N-FAB, who also fitted the front winch mount and side step. The custom roof rack features an LED light bar.
The Engaged suspension components raise the former Sienna more than four inches from stock and allow for more than 15 inches of wheel travel. Those wheels are 22-by-12-inch Monster Energy 539B Off-Road units, wrapped with 33-by-22 Nitto Mud Grappler tires. The vehicle also includes a TRD supercharger and a Wilwood brake kit.
Inside the fully customized interior, a 2500-watt JBL audio system rocks the house, while a night-vision camera system lets occupants keep tabs on the world outside.
Despite Toyota’s impending move to Texas, don’t expect to see the company turning out Sienna minivans like this one any time soon. Toyota describes it as “a one-of-a-kind vehicle, not intended for sale.” Which means the pick-up line at school is safe—for now.
