And the Award for Worst Gas Mileage Ever Goes to This Manual Jeep Cherokee Chief with a Viper V10

Meet the most unapologetically thirsty machine on four wheels: a 1979 Jeep Cherokee Chief restomod packing a 9-liter, 825-horsepower Prefix Viper Gen-V V10 under its Frosted Glass Blue hood.

This isn’t just any swap job—it’s a full-on muscle-truck rebellion, complete with a Tremec TR-6060 six-speed manual, a denim interior, and tribal sidestripes that scream ‘Merica louder than a drag strip at noon.

Built by Vigilante 4×4, this rolling emissions disaster rides on a custom Roadster Shop chassis with Fox dampers, Baer six-piston brakes, and Dana 44/60 axles, all ready to tame the Viper’s 750 lb-ft of torque.

Modern touches like Vintage Air climate control, power windows, Bluetooth audio, and Borgeson power steering keep it civilized—if you can call a V10 this loud civilized. The odometer reads 3,200 miles, but a 2024 engine seizure repair note might give pause.

If you’re chasing the worst gas mileage in history (and the bragging rights that come with it), the auction on Bring A Trailer ends soon—don’t blink.
