The 2027 Mercedes-Benz GLE 450 4MATIC is worth the upgrade over the GLE 350 4MATIC for drivers who want effortless acceleration, heavy-duty towing capability, and smooth inline-six power. Upgrading to the GLE 450 increases output from 255 horsepower to 375 horsepower, cuts the 0–60 mph sprint from 6.8 seconds down to 5.0 seconds, and offers an available third row for extra passenger seating. For everyday luxury highway cruising and confident passing, the enhanced powertrain of the GLE 450 delivers a noticeably higher level of performance.
Both luxury mid-size SUVs share the same spacious two-row cabin architecture, sophisticated MBUX Superscreen digital display setup, and standard 4MATIC all-wheel drive. Choosing between them comes down to driving dynamics, muscle, and towing requirements. The 2027 GLE 350 4MATIC utilizes a refined 2.0-liter turbocharged four-cylinder engine paired with a 48-volt mild-hybrid system, offering plenty of power for daily errands, urban commutes, and family travel. However, if your routine includes trailering a boat, hauling heavy equipment, or tackling hilly highways around Tulsa with a fully loaded vehicle, the 3.0-liter turbocharged inline-six in the GLE 450 4MATIC provides the extra reserve torque you need.
To evaluate both models side by side, our team invites you to browse our new Mercedes-Benz inventory before visiting us in person. You can also stop by our Memorial Drive showroom or call our team directly at (918) 317-1514 to arrange back-to-back road tests.

What Are the Engine, Speed, and 4MATIC Differences Between the GLE 350 and GLE 450?
For the 2027 model year, 4MATIC all-wheel drive is standard on both the GLE 350 and GLE 450, as Mercedes-Benz has discontinued the previous entry-level rear-wheel drive configuration. The primary distinction between these two luxury SUVs lies under the hood, where differences in cylinder count, horsepower, torque output, and acceleration times define their character on the road.
The 2027 GLE 350 4MATIC features a 2.0-liter turbocharged four-cylinder engine integrated with an electric auxiliary compressor and a 48-volt integrated starter-generator. This setup generates 255 hp at 5,800 rpm and 295 lb-ft of torque between 1,800 and 4,000 rpm, with the mild-hybrid system providing a temporary boost of up to 23 hp and 151 lb-ft. Paired with a nine-speed automatic transmission, the GLE 350 4MATIC accelerates from 0 to 60 mph in 6.8 seconds. It delivers balanced power for around-town efficiency while maintaining standard all-weather traction.
Stepping up to the 2027 GLE 450 4MATIC unlocks a 3.0-liter turbocharged inline-six engine, also enhanced by the 48-volt mild-hybrid starter-generator. This powertrain produces 375 hp and 413 lb-ft of torque, enabling the SUV to sprint from 0 to 60 mph in 5.0 seconds—nearly two seconds faster than the four-cylinder model. Beyond straight-line speed, the inline-six design inherently operates with smoother balance, delivering linear power across the rev range.
Here is how the core mechanical specifications stack up:
| Performance Metric | 2027 Mercedes-Benz GLE 350 4MATIC | 2027 Mercedes-Benz GLE 450 4MATIC |
|---|---|---|
| Engine Architecture | 2.0-liter Turbo Inline-4 with Mild-Hybrid | 3.0-liter Turbo Inline-6 with Mild-Hybrid |
| Horsepower | 255 hp | 375 hp |
| Torque | 295 lb-ft | 413 lb-ft |
| 0–60 MPH Time | 6.8 seconds | 5.0 seconds |
| Drivetrain | 4MATIC All-Wheel Drive | 4MATIC All-Wheel Drive |
| Transmission | 9-Speed Automatic | 9-Speed Automatic |
| Maximum Towing Capacity | 7,700 lbs | 7,700 lbs |

How Spacious Is the Third Row in a Mercedes-Benz GLE for Adult Passengers?
The optional third-row seat in the Mercedes-Benz GLE is designed primarily for children or occasional short trips for smaller adults, making it an ideal flexible solution for growing families rather than a full-time adult seating row. While the full-size Mercedes-Benz GLS remains the recommendation for frequent seven-passenger adult travel, the optional 50/50-split folding third row available on the GLE 450 4MATIC offers valuable seating versatility when extra capacity is needed.
In standard two-row configuration, the 2027 GLE features a generous 118-inch wheelbase that delivers spacious legroom and headroom for five adult passengers. The standard 40/20/40-split second-row seats offer optional power adjustability, allowing second-row occupants to slide forward or recline for tailored comfort. Choosing the third-row package adds power-folding functionality to the second row to simplify step-in access to the back row.
When maximum utility is required, folding down both the second and third rows expands total cargo space to roughly 73 cubic feet, creating a broad, flat load floor for luggage, sporting gear, or supplies. Maintaining peak interior functionality and mechanical health requires routine attention; learning more about our Mercedes-Benz service commitment shows how dedicated care preserves your SUV's utility and luxury features over years of driving.

Questions Buyers Ask Before Test Driving the 2027 Mercedes-Benz GLE
Is 4MATIC all-wheel drive standard on both the GLE 350 and GLE 450?
Both the 2027 GLE 350 and GLE 450 models come equipped with standard 4MATIC all-wheel drive, ensuring optimal traction in diverse driving conditions. Mercedes-Benz discontinued the rear-wheel-drive base trim for 2027, ensuring every new GLE SUV delivers standard four-wheel traction, torque vectoring, and enhanced stability in all weather conditions.
How much faster is the GLE 450 compared to the GLE 350?
The GLE 450 4MATIC accelerates from 0 to 60 mph in 5.0 seconds, making it nearly two seconds quicker than the GLE 350 4MATIC, which completes the sprint in 6.8 seconds. The additional 120 horsepower and 118 lb-ft of torque from the 3.0-liter inline-six engine deliver noticeably faster throttle response and effortless highway passing power.
Does the GLE 450 get significantly worse fuel economy than the four-cylinder GLE 350?
Despite its larger engine and higher output, the GLE 450 4MATIC achieves fuel economy figures close to those of the GLE 350 4MATIC. Thanks to its 48-volt integrated starter-generator mild-hybrid technology, the inline-six engine shuts off during coasting and restarts seamlessly, keeping real-world fuel consumption remarkably balanced.
Should I schedule my GLE test drive online or walk into the showroom?
Scheduling your test drive online or calling ahead is recommended. Booking an appointment guarantees that both the GLE 350 and GLE 450 are prepped, fully charged, and waiting for you, allowing for an efficient side-by-side driving comparison without waiting for vehicle staging.
Can I order a third-row seat on both the GLE 350 and GLE 450?
The optional 50/50-split folding third row is available on six-cylinder GLE 450 and V8-powered GLE 580 models. It is not available on four-cylinder models or GLE Coupe variants, making powertrain selection an important factor if seven-passenger seating capability is required.
