2021 Mercedes-Benz GLS Reviews SummaryThe “S” in the 2021 Mercedes-Benz GLS-Class name is meant to connect the SUV to the S-Class flagship sedan. In this sense, the GLS is the S-Class of SUVs, and it delivers on that positioning. The 2021 GLS-Class has three rows of spacious seating, and puts comfort above all else. The GLS can hold groceries, weekend bags, antique desks purchased from a roadside consignment shop—all things that would require a lot of negotiating in the S-Class sedan. The GLS-Class is one member of a growing fraternity of full-size, three-row, luxury SUVs. Their ranks include the Cadillac Escalade, Lincoln Navigator, Infiniti QX80, and the more recent BMW X7. The GLS sets itself apart with a higher standard of luxury, and impressive performance… if you’re willing to shell out the cash. | |
2021 Chevrolet Tahoe Reviews SummaryThe full-size SUV segment is a relatively small one, and Chevrolet dominates it. The Tahoe, and its extended-length twin, the Suburban, account for about half of all big SUV sales despite competitive shortcomings in terms of interior comfort, cargo space, and towing capability. With the all-new 2021 Chevy Tahoe (and Suburban), two of those three flaws are resolved. At the same time, the 2021 Tahoe gets a big upgrade in terms of driving dynamics, technology, and innovation. | |
