In 1999, Car and Driver tested the 2000 GMC Yukon SLT, finding it a significant leap forward in the full-size SUV segment. This wasn’t just an incremental upgrade; it was a refinement of a platform that had already proven successful in GM’s pickup trucks, the Chevrolet Silverado and GMC Sierra. The Yukon’s arrival marked a turning point for larger SUVs, blending power, comfort, and capability into a package that stood out from the competition.
Performance Gains
The new Yukon SLT, equipped with the 5.3-liter Vortec 5300 V-8 engine, delivered noticeable improvements over its predecessor. It accelerated from 0 to 60 mph in 8.6 seconds—a full second faster than the 1999 Chevrolet Tahoe with a 5.7-liter V-8. The quarter-mile time dropped from 17.7 seconds to 16.7 seconds, even with a slightly heavier vehicle weight (5467 lbs).
These performance gains were not just numbers on a test sheet. They translated to a more responsive driving experience, making the Yukon feel more agile than its size suggested. Braking also improved, stopping from 70 mph in 213 feet, compared to the previous Tahoe’s 248 feet.
Handling and Ride Quality
Beyond raw speed, the Yukon SLT offered improved handling and a smoother ride. Steering was precise, eliminating the need for constant corrections on highways. While the solid rear axle still caused some body roll on rough terrain, the overall driving experience was notably better than rivals like the Ford Excursion and Expedition.
The interior was well-designed with logical controls, comfortable seating, and a nine-speaker stereo system. Though the third-row seats were best suited for children, the spacious cabin and available sunroof made long journeys more pleasant.
Off-Road Capability
The Yukon SLT’s four-wheel-drive system, featuring AutoTrac, seamlessly transitioned between rear-wheel and four-wheel drive based on road conditions. With 8.4 inches of ground clearance and all-season tires, it could handle moderate off-road challenges without issue.
Verdict: A Best-in-Class SUV
The 2000 GMC Yukon SLT wasn’t just a good SUV—it was arguably the best full-size SUV on the road at the time. It combined a powerful engine, refined handling, and a practical interior into a package that impressed even the most skeptical automotive critics. This vehicle set a new standard for the segment, proving that GM’s truck platform could be successfully adapted into a premium SUV.
