    Drivers shopping for a comfortable and capable full-size SUV cannot go wrong comparing the 2020 GMC Yukon vs 2020 Chevy Tahoe. Either of these two iconic vehicles can not only handle any adventure, but they can do so while carrying the whole family. However, deciding between the GMC Yukon and Chevy Tahoe can be difficult given the many similarities between these two SUVs. Because GMC and Chevy are both divisions of GM, they share many of their technologies and designs, and the GMC Yukon and Chevy Tahoe are both based on the same basic platform. But while the fundamentals of these SUVs may be similar, that does not mean that they are the same, and the GMC model offers a more premium experience inside and out. Although the 2020 Chevy Tahoe shares almost all of the features of the 2020 GMC Yukon, for the Chevy, many of those features are only options or are locked away on higher trims. Another advantage of the GMC Yukon is its extended length variant, the GMC Yukon XL, which provides far more cargo space as well as a more usable third row of seats. Altogether, the 2020 Chevy Tahoe is an excellent vehicle, but the 2020 GMC Yukon is even better.

    Interior Cargo and Passenger Space

    Drivers considering either the 2020 GMC Yukon or 2020 Chevy Tahoe are probably going to be interested in how much they can haul. And while these two SUVs share the same platform and both offer up to nine seats, when it comes to both passenger and cargo capacity, the GMC Yukon is the clear winner. This is because the GMC Yukon comes in two versions. The standard version shares the same dimensions as the Chevy Tahoe, but there is also an extended length GMC Yukon XL that offers even more cargo space as well as more passenger legroom. 

    The standard GMC Yukon and the Chevy Tahoe both offer up to 94.7 cubic feet of cargo space when all of their seats are folded, providing more than enough room for nearly any cargo. However, that cargo area shrinks to just 15.3 cubic feet when their seats are upright, which can make it difficult to fit everything that might be desired while carrying more than five passengers. 

    Further, the third row in the Chevy Tahoe and standard length GMC Yukon is quite cramped. With just 24.8 inches of legroom fitting full-size adults back there is nearly impossible, and even smaller people will likely be uncomfortable during longer trips.

    Improved Cargo and Passenger Space With the Yukon XL

    These limitations are where the larger 2020 GMC Yukon XL comes in. Nearly two feet longer than either the Chevy Tahoe or the smaller GMC Yukon, the GMC Yukon XL offers a more usable third row and plentiful cargo space no matter how its seats are configured. With all of its seats upright, the extended length SUV offers 39.3 cubic feet of cargo space, giving all seven passengers space for their bags. And if large items such as furniture or hardware need to be moved, then the 2020 GMC Yukon XL has a cavernous 121.7 cubic feet of cargo space when all of its seats are folded. Perhaps more importantly, the third row of seats in the larger vehicle is now fully usable by passengers of all sizes with a comfortable 34.5 inches of legroom. And while it may not be as noticeable, second-row passengers in the Yukon XL can also stretch out a bit more since their legroom is also increased by almost an inch. 

    So while either the 2020 Chevy Tahoe or 2020 GMC Yukon will make a fine vehicle for drivers who do not need more than five seats, the GMC Yukon XL is the only answer for drivers who require a true three-row SUV or who need to move lots of cargo.

    Comfort and Entertainment Features

    Although the 2020 GMC Yukon and 2020 Chevy Tahoe share a platform as well as many features and technologies, that does not mean that the two vehicles are identically equipped. Overall, the GMC Yukon is a more comfortable and feature-rich vehicle than its Chevy counterpart, offering more equipment and luxury items on lower trim levels. For instance, when it comes to seating the 2020 GMC Yukon has eight-way power adjustable front seats with power lumbar support standard on all trims, while even the top trim of the 2020 Chevy Tahoe has simpler six-way adjustable front seats. 

    While all but the base trim of the GMC Yukon come standard with a heated steering wheel, heated seats for both the front row and the second row, and power folding rear seats, these luxuries are only standard on the top trim of the Chevy Tahoe. And for drivers who appreciate good sound quality, every GMC Yukon comes with a premium Bose sound system with nine or ten speakers, including a separate subwoofer. In contrast, the base sound system in the Chevy Tahoe is a simple six speaker setup.

    Infotainment Systems and Other Similar Features

    Still, while the GMC Yukon has the undeniable advantage, many features of these two vehicles are similar. Both SUVs come with standard infotainment systems that include 8” color touch screens and are compatible with both Apple CarPlay and Android Auto for easy integration of all popular smartphones. Navigation is standard on the top trims of both vehicles and is optional on their middle trims. When it comes to physical features, the GMC Yukon and Chevy Tahoe can both be equipped with major items such as sunroofs and hands free power liftgates, as well as more minor but still valuable features. These include power adjustable pedals to better fit the vehicle to the driver and power running boards that make it more convenient to enter and exit these large vehicles.

    What sets the 2020 GMC Yukon and the 2020 Chevy Tahoe apart from most other SUVs on the market is their rugged body on frame construction, rear-wheel drive powertrains, and powerful V8 engines. Although their shared platform means that there are few significant mechanical differences between these two full size SUVs, there are some minor differences in equipment depending on the trim levels compared. 

    Standard Engine Option

    Both the GMC Yukon and the Chevy Tahoe come standard with a 5.3L V8 engine producing 355 horsepower and 383 lb-ft of torque. Although the fuel economy of this engine is not particularly good at 18 MPG combined, it has more than enough power to move these large SUVs along at a comfortable pace.

    Available Engine Option

    However, there is also a larger 6.2L engine that comes standard on the GMC Yukon Denali but is only an option on the Chevy Tahoe Premier. Generating 420 horsepower and 460 lb-ft of torque, the extra power of this larger engine is a valuable addition for everything from pulling a trailer, to traveling off-road, to simply passing slower cars on the highway. The larger engine also comes standard with a superior ten-speed automatic transmission instead of the six-speed automatic that is paired with the base engine, resulting in a smoother ride and improved fuel economy. But while the 6.2L V8 is theoretically available for the 2020 Chevy Tahoe, actually finding a vehicle with that engine may take some searching since the vast majority of them come with the base 5.3L engine.

    Other Performance Features

    A similar pattern holds for other engineering features on these two SUVs. Although the 2020 GMC Yukon has few pieces of equipment that are not available for the 2020 Chevy Tahoe, many standard items on the GMC Yukon are only high trim options on the Chevy Tahoe. For instance, every trim of the 2020 GMC Yukon comes standard with fog lights to aid visibility in bad weather, but this feature is only standard on the top trim of the 2020 Chevy Tahoe and is not available at all on the bottom trim of the Chevy SUV. Trim for trim, the GMC Yukon will always live up to the promise of its more upscale appearance and will be a better equipped vehicle than the Chevy Tahoe. These extra items also tend to make the GMC Yukon the better value as well, as the options needed to bring the Chevy Tahoe up to a comparable configuration will quickly close the price gap between these two SUVs.
