The full-size formula, refreshed
The Yukon's 2025 refresh — carried into 2026 — brought a redesigned cabin around a 16.8-inch portrait touchscreen, new trim architecture (Elevation, AT4, AT4 Ultimate, Denali, Denali Ultimate) and a price ladder that now starts at $72,395 and crests around $103,000 for the Denali Ultimate. Standard and long XL bodies continue; Super Cruise hands-free driving is available.
Three engines cover the range: the 355-hp 5.3-liter V8, the 420-hp 6.2-liter V8, and the quietly excellent 3.0-liter Duramax diesel (~305 hp) — all through a ten-speed automatic, in rear- or four-wheel drive.
The diesel is the connoisseur's pick
Full-size SUV economics rarely reward restraint, but the Duramax does: about 23 mpg combined in rear-drive form against the V8s' 14–17, with locomotive torque that makes its ~8,100-lb tow rating feel effortless. Max towing across the range reaches 8,400 lb. Unless you need the 6.2's soundtrack, the diesel is the range's best engineering.
Space remains the franchise: the independent rear suspension yields a usable third row and enormous cargo, and the XL body turns cargo into a freight category. The Denali Ultimate's cabin — open-pore wood, 18-way massaging thrones — is genuinely luxurious, not merely optioned.
The honest assessment
Two eyes-open items. First, the price walk: today's base Yukon costs what a Denali did not long ago, and a Chevrolet Tahoe delivers the same hardware for meaningfully less — the GMC premium buys badge and trim theater. Second, the known issue: GM's 6.2-liter L87 V8 lifter/bearing failure recall spans roughly 600,000 2021–2024 trucks and SUVs including Yukons. Any used 6.2 needs its recall status and repair documentation verified before purchase.
Size itself is the daily tax — parking garages and school pickup lanes weren't drawn for 210+ inches of truck.
The questions buyers actually ask
Yukon or Tahoe? Mechanically siblings. If the Denali cabin doesn't seduce you, the Chevy is the value answer.
Which engine? Diesel for towing and economy; 6.2 for the experience (with recall diligence on used); 5.3 if the price gap funds better options.
Standard or XL? XL only if you routinely carry seven and their luggage — it's the difference between big and barge.
