Performance on the street and at the work site undergoes a major improvement with the 1999 Ford line-up. The 1999 Ford Mustang has undergone an extensive exterior and equipment upgrade for 1999. Squarer headlamps, sharpened taillight design of the toughened 1999 Mustang is accompanied with greater power from V6 and V8 engines. A Mustang Cobra and 35th Anniversary Limited Edition version of the pony car are also offered. Ford's minivan, the Windstar, is restyled and includes new features such as dual rear sliding doors. Seeking high-performance from a pickup truck, 1999 introduces the Ford F-150 SVT Lightning propelled by a 360-horsepower, supercharged V-8 engine. The Ford truck landscape changes in 1999 with the F-Series Super Duty line. Applying to large pickups three-quarters of a ton in capacity or greater, the 1999 Ford F-Series Super Duty is almost completely distinct compared to the F-150 highlighted by unique styling and mechanical equipment. The F-Series Super Duty also serves as the basis for the new Ford Excursion sport utility vehicle that is larger and heavier than the Expedition.
