2021 Mercedes-Benz GLS Reviews SummaryThe “S” in the 2021 Mercedes-Benz GLS 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 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 Lincoln Navigator Reviews SummaryFull-size SUVs like the Lincoln Navigator represent the smallest slice of the luxury SUV market. They're the heaviest, hugest, and fanciest people movers sold by mainstream automakers—and you can count them all on two hands. The Navigator, a popular nameplate since 1998, was redesigned in dramatic fashion for 2018. In its fourth model year, this Navigator still delights us as we test newer competitors costing at or above its $97,000 starting price. Foreign nameplates offer no equal to the Navigator, and it's not for sheer size or a desire to lift up Lincoln that we say this is one of the best American vehicles, among both trucks and cars, ever made. | |

The 2021 Mercedes-Benz GLS, a continuation of the third generation introduced in 2020, was a luxurious SUV that evolved from the original GL-Class. Initially intended to replace the G-Class, the GLS found its niche among affluent families seeking a spacious, comfortable ride. The GLS's design was more refined than its predecessors, with softened angles and a sleek appearance. Inside, the GLS boasted a futuristic cabin dominated by a massive digital screen, emphasizing its tech-forward approach. Available in three trims—GLS 450, GLS 580, and the high-performance AMG GLS 63—the GLS offered a range of standard features, including remote keyless entry, nine USB ports, and a 13-speaker Burmester sound system. Various option packages allowed for further customization, enhancing comfort and style.
In contrast, the 2021 Lincoln Navigator was a testament to elegance and understatement, despite its imposing size. Sharing its basic structure with the Ford Expedition, the Navigator distinguished itself with unique styling elements and a luxurious interior. The exterior featured simple rectilinear shapes, accented by chrome details, while the interior impressed with its attention to finer details, such as layered wood trim and a minimalist digital instrument panel. The Navigator's Perfect Position seats offered unparalleled comfort with 30-way adjustability. Despite its size, the Navigator's interior was refined, with high-quality materials and tight panel gaps, making it a worthy competitor in the luxury SUV market.















The 2021 Mercedes-Benz GLS offered a range of powerful engines, starting with the GLS 450's twin-turbocharged 3.0-litre inline-six, producing 362 horsepower and 369 lb-ft of torque. The GLS 580 stepped up with a twin-turbocharged 4.0-litre V8, delivering 483 hp and 516 lb-ft. Both models featured a nine-speed automatic transmission and Mercedes' 4MATIC AWD system. The AMG GLS 63, with its hand-crafted 4.0-litre twin-turbo V8, pushed performance to 603 hp and 627 lb-ft, achieving 0-100 km/h in just 4.2 seconds. The GLS's adaptive air suspension and multiple drive modes ensured a smooth, responsive ride, while the EQ Boost system added extra power when needed.
The 2021 Lincoln Navigator, powered by a twin-turbo 3.5-litre V6 from the Ford Raptor, delivered 450 horsepower and 510 lb-ft of torque. Paired with a 10-speed automatic transmission and standard 4WD in Canada, the Navigator offered impressive acceleration and a towing capacity of 3,765 kg. However, its fuel efficiency was less than stellar, averaging 13.8 L/100 km combined. While the Navigator's adaptive dampers provided a comfortable ride, its suspension and steering lacked the precision of competitors like the Cadillac Escalade. Despite this, the Navigator excelled in highway refinement, with a quiet cabin and powerful low-end thrust.
The 2021 Mercedes-Benz GLS provided ample space with its three rows of seating, accommodating up to seven passengers. The front and second rows offered generous headroom and legroom, while the third row was suitable for adults. Cargo space was competitive, with 355 litres behind the third row, expanding to 2,400 litres with all seats folded. The GLS featured numerous storage compartments, including spacious in-door bins and a centre console with butterfly doors.
The 2021 Lincoln Navigator, with its boxy design, offered a spacious interior for up to eight passengers. The third row's middle seat was best suited for children, but the overall space was generous. Cargo capacity was impressive, with 546 litres behind the third row, expanding to 2,925 litres with all seats folded. The Navigator's rear glass opened separately from the tailgate, adding convenience. The front seats were highly adjustable and comfortable, while the large windows and high driving position enhanced visibility.
The 2021 Mercedes-Benz GLS featured the MBUX infotainment system, with a large touch screen and voice-control capabilities. The system included Apple CarPlay and Android Auto, though a USB-C cable was required for connectivity. The digital dash extended to the instrument panel, controlled by touch-sensitive pads on the steering wheel. While there was a learning curve, the system offered a comprehensive tech experience.
The 2021 Lincoln Navigator's 10-inch touchscreen infotainment system felt dated compared to competitors. While it included Bluetooth and SiriusXM, it lacked wireless Apple CarPlay and Android Auto. The 20-speaker Revel Ultima audio system was good but not exceptional. Despite this, the software was intuitive, with fast voice recognition and wireless device charging. The rear entertainment system offered Roku streaming and various connectivity options.
The 2021 Mercedes-Benz GLS came equipped with numerous driver-assistance features, including Active Brake Assist, rain-sensing wipers, and automatic high beams. Additional safety tech included lane-change assist, adaptive cruise control, and blind-spot monitoring. The GLS also featured a full array of airbags, traction control, and a tire-pressure monitoring system.
The 2021 Lincoln Navigator received a five-star overall safety rating from the NHTSA, with four stars for rollover resistance. Standard safety features included automatic emergency braking, lane-keep assist, and blind-spot monitoring. Optional inflatable rear seat belts added an extra layer of safety, though adaptive cruise control was not as advanced as some competitors.
