The redesigned 2021 Yukon XL enters the modern era with an independent rear suspension that improved ride comfort, handling and third-row room. This is a massive vehicle that’s very functional, comfortable and high-tech. The standard 5.3-liter V8 is mated to a 10-speed automatic transmission and together the powertrain supplies plenty of predictable uninterrupted power. The ride is comfortable. Handling is rather ponderous but safe. The enormous cabin is eerily quiet. Cargo capacity is enormous. Controls are very easy to use except for the tricky gear selector. It’s a big step to get into the Yukon XL and the tall hood cuts forward visibility. Forward collision warning and automatic emergency braking with pedestrian detection are standard, but blind spot warning, lane departure and lane keeping assistance are optional. Freshened for 2025, the Yukon XL received new exterior styling and an updated interior featuring a vertically-oriented 16.8-inch infotainment screen. The optional diesel engine got a power bump up to 305-hp. GM's Super Cruise active driver assistance system became available as did optional features that make towing easier. The tricky to operate by feel push-button gear selector was replaced by a column stalk selector.
