2021 Mercedes-Benz GLS vs 2020 Lincoln Navigator

The 2020 Lincoln Navigator was a standout in the luxury SUV segment, thanks to its distinctive design elements that set it apart from its Ford Expedition roots. Designers went to great lengths to give the Navigator a unique identity, with exclusive front and rear styling, the Lincoln Embrace lighting system, and a lattice-type grille featuring an illuminated Lincoln star. The SUV's black roof pillars created a wraparound glass effect, enhancing its premium appearance. Inside, the Navigator offered a luxurious experience with its mid-century modern dashboard, digital instrumentation, and a 10-inch infotainment touchscreen. The interior was bathed in natural light from a panoramic glass roof, and high-quality materials were used throughout, making it a convincingly luxurious flagship SUV.

In contrast, the 2021 Mercedes-Benz GLS presented a more understated yet sophisticated exterior design, with softened angles and lines that belied its size. The GLS's interior was a marvel of modern design, featuring a futuristic cabin dominated by a massive digital screen that spanned nearly two-thirds of the dashboard. This screen highlighted the tech-reliant nature of the GLS, with controls integrated into the digital interface. The GLS was available in three trims, with the AMG GLS 63 offering aggressive styling cues and a performance-inspired interior. The GLS's design was both functional and luxurious, appealing to those seeking a blend of technology and elegance in a family-friendly package.

The 2020 Lincoln Navigator was powered by a robust twin-turbocharged 3.5-litre V6 engine, delivering an impressive 450 horsepower and 510 lb-ft of torque. This engine outperformed the Ford Expedition's most powerful version by 50 horsepower and 30 lb-ft of torque. The Navigator's power was managed by a 10-speed automatic transmission, with power distributed to all wheels via its four-wheel drive system. The SUV offered multiple drive modes, including Conserve, Normal, Excite, Slippery, and Deep Conditions, catering to various driving conditions and preferences. With a maximum towing capacity of 3,764 kilograms, the Navigator was well-suited for hauling, aided by the Pro Trailer Backup Assist system. Despite its size, the Navigator's acceleration was strong, though its fuel efficiency was less impressive, averaging 14.3 litres per 100 kilometres during testing.

The 2021 Mercedes-Benz GLS offered a range of powerful engine options. The entry-level GLS 450 featured a twin-turbocharged 3.0-litre inline-six engine, producing 362 horsepower and 369 lb-ft of torque. The GLS 580 4MATIC boasted a twin-turbocharged 4.0-litre V8, delivering 483 horsepower and 516 lb-ft of torque. The AMG GLS 63, however, was the pinnacle of performance, with a hand-crafted 4.0-litre twin-turbo V8 engine generating 603 horsepower and 627 lb-ft of torque. This engine, paired with a nine-speed AMG twin-clutch automatic transmission, propelled the GLS 63 from zero to 100 km/h in just 4.2 seconds. The GLS's adaptive air suspension and multiple drive modes, including Sport and Sport+, provided a dynamic driving experience, while the EQ Boost system enhanced performance and efficiency.

The 2020 Lincoln Navigator offered a spacious and comfortable interior, with ample room for passengers across all three rows. The optional Luxury Package included 30-way Perfect Position front seats, which, while requiring some time to adjust, provided exceptional comfort. The second row could be configured with either a bench or captain's chairs, and the third row offered class-leading legroom and thigh support. Cargo space was generous, with the standard-length model providing 592 litres behind the third row, expanding to 2,928 litres with all seats folded. The long-wheelbase Navigator L offered even more cargo capacity, making it a practical choice for families.

The 2021 Mercedes-Benz GLS also excelled in interior space, with three rows of seating and ample headroom and legroom for first- and second-row occupants. The standard seven-passenger configuration could be adjusted to six with optional captain's chairs. The third row, while not as spacious as the Navigator's, was still 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's interior featured numerous storage compartments, including spacious in-door bins and a centre console with butterfly doors, providing practicality alongside luxury.

The 2020 Lincoln Navigator's Sync 3 infotainment system was a point of contention, as it was slow to load content. However, it offered a range of features, including Bluetooth, Apple CarPlay, Android Auto, and a 4G LTE Wi-Fi hotspot. The "Phone As A Key" technology allowed drivers to use their smartphone as a key, adding convenience. The 20-speaker Revel Ultima audio system, part of the Luxury Package, delivered an impressive audio experience. Additional technologies included a surround-view camera system and a head-up display, enhancing the Navigator's tech offerings.

The 2021 Mercedes-Benz GLS featured the advanced MBUX infotainment system, with a massive touch screen and a trackpad for easy navigation. The system included Apple CarPlay and Android Auto connectivity, though it required a USB-C cable. The MBUX voice-control system was a standout feature, allowing for complex commands and easy interaction. The digital dash extended to the fully digital instrument panel, controlled by touch-sensitive pads on the steering wheel. This integration of technology made the GLS a leader in infotainment and user experience.

The 2020 Lincoln Navigator came equipped with the Lincoln Co-Pilot360 suite of advanced driver assistance systems, including forward-collision warning, automatic emergency braking, lane-departure warning, and adaptive cruise control. The adaptive cruise control operated smoothly, and the lane-keeping assistance was effective. The Navigator received a five-star overall safety rating from the NHTSA, though the IIHS had not tested the 2020 model.

The 2021 Mercedes-Benz GLS offered a comprehensive array of safety features, including Active Brake Assist, automatic parking assist, and crosswind assist. Additional available safety technologies included lane-change assist, adaptive cruise control, and blind spot monitoring. The GLS was equipped with a full array of airbags, traction control, and a tire-pressure monitoring system, ensuring a high level of safety for occupants.
