As of 2015, plans for the Jeep Gladiator, which remains a concept vehicle, include a fold-down windshield, open-air canvas, removable doors, expandable truck bed and 18-inch wheels. The vehicle is expected to be based on Jeep's original World War II military vehicle SJ platform.
Jeep introduced the Gladiator concept in 2005, presenting it as a "lifestyle" pickup truck capable of converting from a comfortable conveyance to an off-road vehicle or work truck with a few minor adjustments. For example, its rear seat cushion is easily stored away, while its bed is variable in length, from 5 feet and 8 inches to 8 feet and 11 inches.
Those in the automotive industry expect the Gladiator to feature a 2.8-liter turbo diesel engine or a 3.6-liter V6 gasoline engine and a manual five-speed transmission or six-speed automatic. It is expected to reach 60 miles per hour within 7.7 seconds, which is considered fast for a sports utility vehicle or pickup truck.
Those who have reviewed prototypes of the Gladiator laud its comfortable interior and quality upholstery. However, some say the cab is noisy when used on the highway.
Jeep produced a Gladiator pickup truck, also built on the military SJ platform, from 1962 until 1971.
