The Suburban and Yukon XL are essentially twins, although not quite identical, and the same is true of the Tahoe and Yukon. There are differences between the Chevy and GMC versions, such as the differences in appearance (their grilles are distinctly different) and overall dimensions (the Suburban is slightly longer and wider than the Yukon XL; the Tahoe is slightly longer and not quite as tall as the Yukon). But the standard and optional engines (including a turbodiesel and a 420 hp 6.2L V8), transmissions, and other factors (dependent on trim levels, available infotainment, connectivity, navigation, safety, and driver assist technology) are the same for all. And all are available with RWD or 4WD.Â
The Suburban and Yukon XL are identical in EPA fuel economy, fuel capacity, driving range, cargo volume, payload, GVWR, towing capacity, and front head, leg, and shoulder room; the Tahoe and Yukon are also identical to each other in these factors. Â
GMC vs. Chevy Base Price and Trim Levels
The GMC versions' base price is about $2,000 more than their Chevy counterparts because the GMC versions are considered more luxurious. But that can be evened out when selecting trim levels. The Suburban and Tahoe each offer six trim levels. Even the lowest, the LS, is well-equipped with standard convenience, safety, and technology features; the highest level is the High Country. Both the Yukon XL and Yukon offer four trim levels; the base SLE is by no means a stripped-down model, while the AT4 has features recommended for off-roading, and the Denali trim level provides a level of luxury surpassed only by the Cadillac Escalade.
