The Yukon's ride is supple and controlled. Interior quality and the seats are good, and it has impressive trailer-towing capability. The 5.3-liter engine does the job, but the Tahoe twin we tested delivered only 14 mpg overall. Denali models have a powerful 6.2-liter V8. A six-speed automatic is standard. The Yukon typically seats seven or eight but offers little cargo space behind its cramped and very low third-row seat. 4WD models have a selectable full-time system that can remain engaged at all times without worry. ESC is standard. A hybrid got a respectable 19 mpg overall in our tests.
