2021 Mercedes-Benz GLB vs 2022 Cadillac XT6

The 2021 Mercedes-Benz GLB, introduced in 2020, was a fresh addition to the Mercedes-Benz SUV lineup, fitting snugly between the smaller GLA and the larger GLC. Despite its unique dimensions, the GLB shared a strong family resemblance with its lineup mates, making it difficult to distinguish without checking the badge. Its design was characterized by a sporty and athletic stance, aided by a generous 20 centimetres of ground clearance, which was more forgiving on uneven roads compared to the lower-slung GLA and GLC. Inside, the GLB impressed with its modern and stylish cabin, featuring a striking repetition of round shapes across the dashboard and polished metal details that evoked an aerospace vibe. The single panel housing both the virtual instrument cluster and infotainment screen added to the elegance, while the fit and finish were of the high standard expected from Mercedes-Benz.

In contrast, the 2022 Cadillac XT6 presented a more conservative and tailored image, with its polished 20-inch alloy wheels and Stellar Black paint. The XT6's design was attractive yet blandly inoffensive, with towering front running lights that made it appear tall and narrow. The rear taillights bore a resemblance to those used by GMC, lacking distinctive flair. Inside, the XT6's cabin, while lined with rich materials, did not exude the luxury expected at its price point. The analog gauges and 8-inch touchscreen display felt outdated compared to its competitors, though the intuitive infotainment system and voice recognition technology were commendable. Despite its premium leather interior and advanced driving assistance technologies, the XT6's interior layout and controls felt more akin to those in lower-priced GM models.

The 2021 Mercedes-Benz GLB was powered by a turbocharged 2.0-litre inline-4 engine, delivering 221 horsepower and 258 lb-ft of torque. This engine was paired with an eight-speed dual-clutch automatic transmission, providing a smooth and predictable power delivery. The GLB's 4MATIC all-wheel-drive system was standard in Canada, enhancing handling in various weather conditions and offering better driving feel on dry roads. With a curb weight of 1,765 kilograms, the GLB managed a 0-100 km/h time of 6.9 seconds, with a top speed of 210 km/h. Its fuel consumption was estimated at 11.1 litres per 100 kilometres in the city and 8.9 on the highway.

The 2022 Cadillac XT6, on the other hand, offered two engine options. The base model featured a turbocharged 2.0-litre four-cylinder engine with 235 horsepower and 258 lb-ft of torque, paired with a nine-speed automatic transmission. The Premium Luxury and Sport trims came with a 3.6-litre V6 engine, producing 310 horsepower and 271 lb-ft of torque. While the V6 provided sufficient power, it lacked the turbocharged punch found in some competitors. The XT6's adaptive-damping performance suspension and 20-inch wheels contributed to its athletic handling, though the driving experience leaned more towards comfort and serenity. The XT6's fuel economy was rated at 11.5 litres per 100 kilometres in combined driving, with our test vehicle returning 12.0 L/100 km.

The 2021 Mercedes-Benz GLB offered a flexible interior layout, with the option to add a third-row seat. The second row featured a 40:20:40 split seatback and a 40:60 split seat bottom, allowing for individual adjustments and sliding capabilities. In the five-passenger configuration, the GLB provided 764 litres of cargo space behind the second row, expanding to 1,755 litres with the seats folded. The seven-passenger version offered 144 litres behind the third row, 679 litres behind the second, and 1,605 litres with all seats down. The third row was best suited for children or short trips due to limited legroom and headroom.

The 2022 Cadillac XT6, while expected to offer ample space, felt narrower inside. The front seats were comfortable and wrapped in premium leather, but lacked the range of adjustments found in some rivals. The second-row captain's chairs provided good legroom, but the third row was cramped and challenging to access. Cargo space behind the third row was 357 litres, with a maximum volume of 2,229 litres when the rear seats were folded. Storage compartments were limited, with small cubbies and bins.

The 2021 Mercedes-Benz GLB was equipped with the latest Mercedes-Benz User Experience (MBUX) infotainment system, featuring voice control and natural language understanding. Standard technology included a 7-inch digital instrument cluster and touchscreen display, with options to upgrade to 10.25 inches. The GLB offered smartphone integration, a power liftgate, and optional features like a Burmester Surround Sound System, augmented reality navigation, and adaptive suspension damping.

The 2022 Cadillac XT6 featured a mix of advanced and outdated technology. While it offered a digital rearview mirror, Night Vision, and Super Cruise hands-free driving assistance, it lacked digital gauges and had an 8-inch touchscreen display. The infotainment system was intuitive, with wireless Apple CarPlay and Android Auto, but some controls were counterintuitive. The available Bose Performance Series audio system and digital rear camera were highlights, though the head-up display was less impressive.

The 2021 Mercedes-Benz GLB came with a suite of standard safety features, including active brake assist, adaptive braking technology, and crosswind assist. Optional safety packages added features like adaptive cruise control, blind-spot monitoring, and active lane-keeping assist. The GLB also featured Pre-Safe technology, which activated safety measures in the event of an imminent collision. However, it had not been rated by the NHTSA or IIHS.

The 2022 Cadillac XT6 was equipped with a comprehensive list of safety features, including forward collision warning, automatic emergency braking, and blind-spot monitoring. The standout feature was the Super Cruise system, which allowed for hands-free highway driving. The XT6 received a Top Safety Pick+ rating from the IIHS and five-star ratings from the NHTSA, demonstrating its strong safety credentials.
