2021 Mercedes-Benz GLB vs 2021 Toyota Sienna

The 2021 Mercedes-Benz GLB, introduced in 2020, was a fresh addition to the Mercedes-Benz SUV lineup, fitting between the smaller GLA and the larger GLC. With a length of 4.63 metres and a wheelbase of 2.83 metres, it was slightly larger than the GLA but just shy of the GLC. Despite its distinct dimensions, the GLB shared the signature Mercedes-Benz styling, making it difficult to distinguish from its siblings without checking the badge. Its athletic stance was enhanced by a 20-centimetre ground clearance, offering a more forgiving ride over soft roads and speed humps. Inside, the GLB boasted a modern and striking design, with round shapes across the dash and polished metal HVAC vents that evoked an aerospace vibe. The cabin's fit and finish were of the high standard expected from Mercedes-Benz, with a single panel housing both the virtual instrument cluster and infotainment screen.

The 2021 Toyota Sienna Hybrid aimed to redefine minivan aesthetics with its SUV-like styling. A wide grille and sleek LED headlamp arrays gave it a modern look, while the redesigned sliding side doors added an assertive stance. The Sienna's exterior was marked by superb Toyota quality, with alloy wheels ranging from 17 to 20 inches, depending on the grade. Inside, the Sienna emphasized width with horizontal lines, offering a higher seating position than a sedan for a comfortable ride. The dashboard was simple and uncluttered, with controls conveniently clustered below the infotainment screen. The centre console featured a gear selector lever, cupholders, and a large storage compartment, while the second and third-row seats provided ample comfort and flexibility for passengers.

The 2021 Mercedes-Benz GLB was powered by a turbocharged 2.0-litre inline-4 gasoline engine, delivering 221 horsepower and 258 lb-ft of torque. Paired with an eight-speed dual-clutch automatic transmission, the GLB offered a 0-100 km/h time of 6.9 seconds and a top speed of 210 km/h. Its 4MATIC all-wheel drive system provided better handling in various conditions, with features like hill-start assist and downhill speed regulation. The GLB's fuel consumption was estimated at 11.1 litres per 100 kilometres in the city, 8.9 on the highway, and 10.1 combined.

The 2021 Toyota Sienna Hybrid featured a 2.5-litre four-cylinder engine combined with two electric motors, producing a total of 243 horsepower. It offered front-wheel drive as standard, with an all-wheel drive option available. The Sienna's electronically controlled continuously variable automatic transmission (CVT) provided smooth power delivery, though it lacked the punch of a conventional transmission. The Sienna's fuel efficiency was impressive, with FWD models rated at 6.6 litres per 100 kilometres in the city, 6.5 on the highway, and 6.5 combined, while AWD models were slightly higher. The Sienna's handling was improved with new suspension systems, offering a comfortable and stable ride.

The 2021 Mercedes-Benz GLB offered the option of a third-row seat, which affected the second row and cargo compartments.

In the seven-passenger GLB, the third row was retractable, providing flexibility for passengers or cargo. Cargo space varied from 764 litres in the five-passenger model to 1,605 litres in the seven-passenger model. The front seats were highly adjustable and supportive, with available heated and ventilated options.

The 2021 Toyota Sienna excelled in convenience functions, with a standard third-row 60/40-split bench that stored away easily.

The Sienna's cargo capacity was impressive, with 949 litres behind the third row, 2,129 litres behind the second row, and 2,860 litres behind the first row. The Sienna could also tow up to 1,587 kilograms, and its hybrid battery was cleverly tucked under the front seats, preserving cargo space.
