This crossover vehicle is at once an SUV and a pickup truck. It is a very strong, powerful, and useful vehicle that does not cut corners when it comes to passenger comfort. The Ford Explorer Sport Trac is rather fuel inefficient, whichever engine used. The 210 horsepower V6 engine is penalized by its five-speed automatic transmission, while the 292 horsepower V8 and its six-speed automatic transmission is barely thirstier. It is available with rear-wheel drive or with 4x4 configuration.
