Wagon or SUV? Exploring Two Mercedes-Benz Approaches to Versatility
January 20 2026,
Families seeking premium versatility face a choice: the raised ride height of a compact luxury SUV, or the refined practicality of a wagon designed for both pavement and light terrain. The 2026 Mercedes-Benz E 450 All-Terrain and the 2026 GLC 300 offer distinct approaches to everyday luxury and capability, each with unique advantages for drivers across Quebec.
Both vehicles feature standard 4MATIC all-wheel drive, advanced technology, and refined interiors. Their differences in design philosophy, cargo capacity, and driving character create a more nuanced decision than it might first appear.
Performance and Powertrain
The E 450 All-Terrain delivers notably more power through its 3.0L inline-6 turbo engine with 48-volt mild hybrid technology. The system produces 375 hp and 369 lb-ft from the combustion engine alone, with an additional 23 hp and 151 lb-ft available from the integrated starter-generator. This setup enables acceleration from 0 - 100 km/h in an estimated 4.7 seconds.
The GLC 300 takes a more efficient approach with its 2.0L inline-4 turbo engine paired with mild hybrid drive. Output reaches 255 hp and 295 lb-ft, delivering 0 - 100 km/h acceleration in 6.2 seconds. While less potent on paper, the GLC's lighter curb weight of 1,910 kg ensures responsive everyday performance.
Both vehicles feature 9-speed automatic transmissions and DYNAMIC SELECT drive modes, allowing drivers to tailor throttle response, transmission behaviour, and suspension settings to suit conditions. The E 450 All-Terrain includes a dedicated Off-Road mode and transparent hood display through its 360° camera system, enhancing capability on unpaved surfaces.
Dimensions and Practicality
Cargo capacity shows a key distinction. The E 450 All-Terrain offers 615 litres behind the second row, expanding to 1,830 litres with the 40:20:40-split rear seats folded. The GLC 300 provides 620 litres to 1,680 litres in the same configurations - competitive figures, but the wagon's lower load floor and wider opening make loading bulkier items easier.

The All-Terrain's longer wheelbase translates directly into second-row comfort. Rear passengers enjoy 1,519 mm of elbow room, while the extended wheelbase creates additional kneeroom and legroom compared to the more compact GLC.
Suspension and Handling
Standard AIRMATIC air suspension sets the E 450 All-Terrain apart. This system pairs air springs with adaptive ADS+ dampers that adjust compression and rebound characteristics at each wheel independently.
Level control maintains consistent ground clearance regardless of load, while automatically lowering the vehicle at highway speeds to reduce wind resistance and improve fuel efficiency.
The GLC 300 employs a 4-wheel independent suspension with selective damping - a capable setup that balances comfort and control, though without the adaptive height adjustment of the All-Terrain's air system. The GLC's turning circle of 11.8 metres (wall-to-wall) makes it more manoeuvrable in tight urban environments compared to the wagon's longer footprint.
Interior and Technology
Both vehicles feature Mercedes-Benz's third-generation MBUX infotainment system with a 12.3-inch digital instrument cluster and 11.9-inch central touchscreen. Voice Control with Natural Language Understanding, wireless Apple CarPlay and Android Auto, and over-the-air software updates come standard across both models.
The E 450 All-Terrain's cabin benefits from the E-Class platform's focus on long-distance comfort. Standard equipment includes:
- Power-folding rear seats operated by push buttons on each side of the backrest
- Retractable two-piece luggage cover
- EASY-PACK power tailgate with multiple activation methods
The GLC 300 counters with its own convenience features: power front seats with memory, heated front seats, KEYLESS-GO, and a versatile cargo area with retractable luggage cover. Optional packages like Exclusive Trim and Pinnacle Trim add Climate Comfort front seats, enhanced ambient lighting, and panoramic sunroof.
Capability and Towing
The E 450 All-Terrain's off-road focus includes standard 19-inch wheels (20-inch optional), unique bumpers with chrome underride guards, and dark grey wheel arch cladding. Ground clearance and approach angles favour light terrain navigation - gravel roads, cottage trails, and winter conditions where the air suspension can raise the vehicle for additional clearance.
The GLC 300 is rated to tow up to 1,588 kg (3,500 lbs), making it suitable for small trailers, lightweight boats, or utility trailers for weekend projects.
Fuel Economy
The GLC 300's smaller engine and lighter weight deliver efficiency advantages. Fuel consumption registers at 9.9 L/100 km city and 7.7 L/100 km highway.
The E 450 All-Terrain's larger inline-six returns 10.6 L/100 km city and 7.6 L/100 km highway - remarkably similar highway figures despite the power difference, thanks to the mild hybrid system's energy recuperation and the aerodynamic benefits of the wagon's lower roofline.
Both vehicles feature 48-volt mild hybrid systems that enable efficient engine start-stop functionality, energy recuperation during deceleration, and brief electric-only operation at low speeds.
Which Vehicle Fits Your Needs?
The E 450 All-Terrain excels for drivers prioritizing maximum cargo versatility, long-distance comfort, and light off-road capability. Its air suspension delivers refined ride quality, while the inline-six engine provides effortless power for highway passing and merging. The wagon's lower load height simplifies loading sports equipment, luggage, or home improvement materials.
The GLC 300 appeals to those seeking a more compact footprint without sacrificing capability. Its higher seating position provides better visibility in traffic, while the smaller dimensions make parking and urban navigation less stressful. The GLC's towing capacity and competitive cargo space make it a practical choice for active families.
Both vehicles deliver Mercedes-Benz's signature blend of luxury, technology, and all-weather confidence. For drivers who frequently load large items or prioritize highway comfort, the E 450 All-Terrain offers clear advantages. For those navigating tighter spaces or towing light trailers, the GLC 300 provides a more practical solution.
