2026 Mercedes-Benz GLS vs 2026 Volkswagen Atlas

The 2026 Mercedes-Benz GLS lineup, including the GLS 450, GLS 580, AMG GLS 63, and Maybach GLS 600, was a testament to luxury and performance. With Canadian prices ranging from $125,395 to $247,795, this SUV was built in Alabama and subject to tariffs, excluding the federal luxury tax on amounts over $100,000. Our test vehicle, the GLS 450, featured 21-inch AMG wheels, the AMG Line Exterior Package, premium leather upholstery, and a black headliner. The AMG styling details added a sporty flair, resolving the awkward fake front skid plate standard on the GLS 450. Inside, the GLS shared similarities with the smaller GLE, boasting high-quality materials and detailing. However, body creaks were noticeable on chilly mornings. The interior offered leather as standard, with Nappa leather and various trim options available. The dual 12.3-inch displays were well-integrated, providing a seamless dashboard experience.

The 2026 Volkswagen Atlas, particularly in the Execline trim, exuded an upscale appearance, bordering on luxury crossover territory. Starting at $64,492, the Atlas looked more expensive than it was, with the base Comfortline trim beginning at $54,492. The Atlas featured full-LED lighting, power-adjustable heated side mirrors, and a sculpted silhouette. The Peak Edition added rugged elements, while the Execline boasted 21-inch two-tone alloy wheels and R-Line design elements. Our test vehicle's Pure Grey paint resisted dirt, and the Titan Black upholstery with a silver underlay added a touch of light. Inside, quilted diamond-pattern leather seats and metallic accents created a warm environment. However, the MIB3 infotainment system was frustrating to use, with touch-sensitive controls that were invisible at night. Despite this, the Atlas offered competitive space and cargo capacity, making it a practical choice for families.

The 2026 Mercedes-Benz GLS 450 was powered by a turbocharged 3.0-litre inline-six-cylinder engine with mild-hybrid assist, delivering 375 horsepower and 369 pound-feet of torque. Coupled with a nine-speed automatic transmission and standard 4Matic AWD, it accelerated from 0-100 km/h in 6.1 seconds. The GLS 450 offered a balance of power and fuel economy, rated at 11.3 L/100 km combined by Natural Resources Canada, though our test observed 12.1 L/100 km. The Dynamic Select system provided multiple driving modes, and the Airmatic adaptive suspension enhanced ride quality. With a towing capacity of 3,500 kilograms, the GLS was versatile, offering a tailored driving experience with a quiet cabin and composed ride.

The 2026 Volkswagen Atlas retained its turbocharged 2.0-litre inline four-cylinder engine, producing 269 horsepower and 273 pound-feet of torque. Paired with an eight-speed automatic transmission and standard AWD in Canada, it offered a 0-100 km/h time of roughly eight seconds. The engine's wide torque band provided flexibility, though initial acceleration felt adequate rather than eager. The Drive Mode Select system included Eco, Comfort, Sport, Custom, and Snow options, with Sport mode enhancing throttle response. Our test recorded 10.7 L/100 km, slightly better than the estimated 11 L/100 km combined for the Execline trim. The 4Motion AWD system performed well in varied conditions, though the Atlas's ride quality suffered due to its large wheels, transmitting vibrations on imperfect surfaces.

The 2026 Mercedes-Benz GLS offered standard seven-passenger seating, with a six-passenger option featuring second-row captain’s chairs. The GLS was exceptionally comfortable, accommodating up to seven adults. Standard features included a four-zone climate control system, heated, ventilated, and massaging front seats, and heated second-row seats. Comfort upgrades included ventilated and massaging second-row seats and a five-zone climate control system. The six-passenger configuration provided power-operated and heated captain’s chairs. Cargo space was 355 litres behind the third row, expanding to 2,400 litres with seats folded. However, storage locations were limited, and the cargo cover was cumbersome during loading.

The 2026 Volkswagen Atlas excelled in accommodating passengers and cargo. The Execline’s front seats were heated, ventilated, and equipped with massage, with supportive seating for long drives. The second row featured captain’s chairs, allowing easy access to the third row. The third-row seats provided decent leg support, and cargo capacity was a strong point. With 583 litres behind the third row, expanding to 2,735 litres with seats folded, the Atlas offered competitive space, making it ideal for families and long trips.

The 2026 Mercedes-Benz GLS featured dual 12.3-inch displays with the MBUX infotainment system, offering wireless Apple CarPlay and Android Auto, a navigation system with augmented reality, and a Burmester surround-sound system. The system was user-friendly, with a digital assistant activated by “Hey Mercedes.” Additional options included a head-up display and rear infotainment screens. The GLS’s technology was straightforward, focusing on simplicity and functionality.

The 2026 Volkswagen Atlas came with a 12-inch touchscreen running the MIB3 system, a 10.25-inch Digital Cockpit Pro, wireless Apple CarPlay and Android Auto, and a Harman Kardon audio system on higher trims. However, the MIB3 system was frustrating, with touch-sensitive controls invisible at night. The voice control system was unreliable, making Apple CarPlay or Android Auto preferable. Despite attractive graphics, the Atlas’s tech prioritized form over function, complicating basic tasks.

The 2026 Mercedes-Benz GLS included nearly 40 safety and driver assistance systems, such as Pre-Safe and Crosswind Assist. It featured a Car-to-X Communication system and parking aids. However, it lacked hands-free highway driver assistance, requiring active driver participation. The GLS’s safety systems were reliable, though some features, like curve speed reduction, were overly cautious.

The 2026 Volkswagen Atlas earned a five-star safety rating from NHTSA and was a Top Safety Pick+ by IIHS. The IQ.Drive suite was standard, offering features like forward-collision warning, blind-spot monitors, and adaptive cruise control. The systems performed well in varied conditions, providing reliable assistance without being intrusive. The Execline added Park Assist, though the Atlas was easy to maneuver without it.
