Cadillac Escalade I (GMT400) gallery (1998–2000)
First generation of the full-size luxury body-on-frame SUV Cadillac Escalade, introduced in 1998 to compete against the Lincoln Navigator featuring advanced engineering solutions.
The first generation Cadillac Escalade debuted in late 1998 as General Motors' swift strategic answer to the rapidly emerging popularity of the Lincoln Navigator. Constructed on GM's rugged GMT400 body-on-frame truck architecture under the GMT435 internal designation, the Escalade shared its underlying structure with the GMC Yukon Denali. Exterior styling set the vehicle apart through a custom chrome grille design bearing the Cadillac crest, unique front and rear bumpers, protective body-side cladding, and model-specific aluminum wheels. Offered exclusively as a five-door full-size luxury SUV, the vehicle projected a commanding road presence with integrated running boards. Inside, the cabin offered plush leather upholstery, genuine Zebrano wood trim accents, enhanced acoustic insulation, and eight-way power-adjustable heated front bucket seats with position memory settings.
Powertrain responsibilities were handled by a 5.7-liter Vortec 5700 V8 gasoline engine producing 255 horsepower and 330 lb-ft of torque. The V8 was mated to a heavy-duty four-speed 4L60-E automatic transmission paired with an AutoTrac selectable all-wheel-drive system capable of automatically engaging front-axle traction under wheel slip conditions. Standard factory luxury features included a custom-tuned Bose seven-speaker sound system, tri-zone climate controls, the OnStar safety communications system, and keyless entry. Production ran through the 2000 model year, successfully laying the foundation for Cadillac's long-term dominance in the full-size luxury SUV segment.
