Should You Buy a 2024 Mercedes-Benz GLE 450e?

The 2024 Mercedes-Benz GLE 450e is the plug-in hybrid version of the redesigned GLE lineup, offering a promised 77 km of electric range.

Strengths

• Impressive electric range
• Spacious interior and cargo space
• Same price as the gas-powered GLE 450

Weaknesses

• Average acceleration
• Visibility issues

The 2024 Mercedes-Benz GLE lineup saw considerable upgrades this year, and perhaps the biggest surprise was the addition of the GLE 450e plug-in hybrid (PHEV). Aimed at providing both performance and efficiency in the midsize luxury SUV segment, the GLE 450e combines a 23.3-kilowatt-hour battery with a two-liter inline four-cylinder turbo engine, delivering a total of 381 horsepower and 479 pound-feet of torque. On paper, it offers up to 77 kilometers of all-electric range, positioning it as an appealing option for daily commuters seeking to limit fuel use.

The GLE 450e isn’t just about fuel economy. Reaching 100 kilometers per hour in 6.1 seconds, it provides brisk, albeit tempered, acceleration. Mercedes has also enhanced its off-road capabilities with features like the transparent hood system, which helps drivers maneuver over rough terrain, while the new MBUX infotainment system brings user-friendly tech to the experience. With an enticing blend of luxury and eco-conscious driving, the GLE 450e makes a compelling case. But does it have enough to stand out among the competition? Here’s a closer look at reasons to buy and points to consider before committing.

Reasons to Buy the 2024 Mercedes-Benz GLE 450e

1. Ample Electric Range That’s Easy to Maximize

While its electric range may not lead the segment, the GLE 450e proves efficient and easy to manage in all-electric mode. During real-world testing, it was possible to complete daily commutes with a mix of city and highway driving without using any gasoline. This is a standout benefit for those looking to maximize electric power in a plug-in hybrid, and the GLE 450e’s seamless switch between power sources makes it user-friendly without sacrificing driving freedom.

2. Spacious and Refined Interior

Mercedes has provided the GLE 450e with a roomy and comfortable interior, making it a practical choice for families. With substantial second-row legroom and ample cargo space, it’s as functional as it is luxurious, providing the same practicality as other GLE models. This combination of space, high-end materials, and thoughtful design makes it one of the most welcoming interiors among luxury PHEVs, especially for families with young children.

3. Efficient Charging Options

The GLE 450e supports charging on Level 1, Level 2, and Level 3 outlets, giving owners flexibility. In our test, charging from 12% to 100% on a Level 2 home charger took about four hours, even in cold weather, while a Level 3 fast charger can reach 80% in approximately 20 minutes. For most owners, a Level 2 charger at home will keep the vehicle ready for regular commutes, ensuring that you rarely need to rely on the gas engine.

4. Practical and Adaptable Electric Capabilities

The GLE 450e offers multiple driving modes—electric, hybrid, and battery hold—through its Dynamic Select system, along with adjustable regenerative braking via shift paddles. This allows drivers to optimize energy usage and control how the vehicle behaves on electric power alone. With an EV top speed of 140 kilometers per hour, the GLE 450e performs well under all-electric acceleration, providing a seamless experience that makes electric driving feel natural.

5. Noticeable Efficiency Gains and Competitive Pricing

In terms of fuel savings, the GLE 450e has a clear advantage over the mild hybrid GLE 450. Over a week of combined driving, we achieved a fuel consumption average of 3.8 liters per 100 kilometers over 500 kilometers—a clear edge over comparable mild hybrids. And with the GLE 450e’s starting price of $90,100, nearly identical to that of the GLE 450, it offers real value for buyers seeking both luxury and efficiency.

6. Good Towing Capacity

For a PHEV, the GLE 450e offers a commendable towing capacity of up to 2,700 kilograms. While this is less than the GLE 450’s 3,500-kilogram capability, it’s an impressive figure for a hybrid model. It provides a useful towing option for those needing moderate capability without compromising the PHEV’s benefits.

7. Improved, User-Friendly MBUX Infotainment System

The new-generation MBUX system in the GLE 450e offers easy navigation and a responsive interface, with a layout that feels intuitive rather than overwhelming. While it doesn’t feel dramatically different from its predecessor, the simplicity and ease of access to key features are clear advantages. However, there are occasional issues with wireless Apple CarPlay connectivity, with occasional unexpected disconnections, which may be a minor frustration for some drivers.

Reasons You Might Not Buy the 2024 Mercedes-Benz GLE 450e

1. Underwhelming Performance Compared to Rivals

Despite having more horsepower than the GLE 450, the GLE 450e doesn’t quite match the performance of its non-hybrid sibling, and it feels noticeably slower than competitors like the BMW X5 PHEV, Range Rover Sport PHEV, and Cayenne E-Hybrid. With a heavy feel and subdued acceleration even in sport mode, it lacks the punch many expect from a GLE and feels closer to the base GLE 350 than the GLE 450. For those seeking an engaging drive, this could be a dealbreaker.

2. Limited Off-Road Clarity in Camera Systems

The GLE 450e’s off-road camera systems, including the transparent hood feature, aren’t as effective as expected. The screen resolution can make it difficult to identify obstacles, limiting the usefulness of these features in challenging terrain. For serious off-roaders, other models may offer better clarity and confidence.

3. Importance of Proper Winter Tires

While this isn’t an inherent fault of the GLE 450e, it’s essential to select the right winter tires. The Pirelli Scorpion tires that can be installed by dealers on the original wheels struggled for traction in snowy conditions, making for a challenging drive during a winter storm. For those planning to drive in winter weather, choosing a different set of tires or downsizing for improved grip is highly recommended.

Conclusion

The 2024 Mercedes-Benz GLE 450e presents a compelling choice in the luxury PHEV segment, offering substantial all-electric range, spacious comfort, and a suite of advanced features. Its practicality as a family vehicle, combined with reasonable fuel efficiency and a competitive price point, makes it an attractive option for buyers seeking a refined yet eco-friendly SUV.

However, the GLE 450e’s performance might not satisfy drivers looking for a dynamic experience, as it lacks the spirited handling and acceleration found in some of its rivals. While its off-road features and towing capacity add versatility, these aspects could be limited by the camera system’s clarity and the need for high-quality winter tires in harsher climates.

In the end, the GLE 450e offers solid value and practical features for those prioritizing luxury and efficiency. For drivers who are more focused on performance and dynamic handling, however, exploring other options within or outside of the Mercedes lineup may be worthwhile.
