Long before the luxury SUV segment became popular in the 1990s, the vehicle in this segment was the 1966 Jeep Super Wagoneer,[48][49][50](p3) which was marketed at the time as a station wagon. It was the first off-road SUV to offer a V8 engine, automatic transmission, and luxury car trim and equipment.[51] Standard equipment included bucket seating, a center console, air conditioning, seven-position tilt steering wheel, a vinyl roof and gold colored trim panels on the body sides and tailgate.[50](p3) By the late 1970s, optional equipment included an electric sunroof,[50](p4) The 1978 Jeep Wagoneer Limited was the spiritual successor to the Super Wagoneer and was the first four-wheel drive car to use leather upholstery.[50](p5)
Another precursor to the luxury SUV is the Range Rover, which was released in 1970. It was the first road-going vehicle to have a permanent four-wheel drive system, split tailgate, clamshell bonnet and continuous waistline (in the same vehicle).[52] The Range Rover had long-travel coil spring suspension and an aluminium V8 engine.[53] Development of the Range Rover began in 1951.[54]
In the mid 1990s, the SUV market expanded with new entrants. By the mid-1990s, the entry-level Ford Explorer and upscale Jeep Grand Cherokee were the market leaders for SUVs.[55] The fastest growing sector of this market was for the so-called luxury SUVs, which included the Jeep Grand Cherokee … the Grand Cherokee’s allure: “This vehicle is proof you can have a true off-road vehicle without giving up luxuries and amenities” with the Jeep providing a crucial new intangible factor for buyers—image.[56]
The SUV models generated higher profit-margins than passenger cars, and car manufacturers began introducing new luxury SUVs during the late 1990s.[57] SUVs such as the 1995 Lexus LX, 1997 Mercedes-Benz M-Class and 1998 Lincoln Navigator were the first SUVs produced by these luxury car brands. Some of these early luxury SUV models used a unibody construction, becoming part of the trend moving away from the body-on-frame construction traditionally used by off-road vehicles
