Doug DeMuro gave the 2026 Mastiff Armored Truck a positive 77/100 OctaneScore, praising its exceptional design and cabin technology—particularly the nearly 3-inch-thick armored glass that still rolls down and the thermal imaging camera with joystick-controlled LED searchlight. Performance and livability are strong as well, with the truck handling surprisingly well despite 5,000 pounds of armor and featuring hydraulic-assist doors plus an armored safe for valuables. The main drawbacks are the steep $400,000+ price tag for only 21 civilian units and poor 6 mpg fuel economy, though the massive 100+ gallon fuel capacity helps offset range concerns. The Mastiff is purpose-built for those who prioritize security and luxury amenities over affordability and efficiency.
