Mercedes-Benz GLE L: New Long Wheelbase SUV Debuts in China With Powerful Engines and Premium Features

Mercedes-Benz GLE L: Mercedes-Benz has expanded its popular GLE SUV lineup with a new long wheelbase version in China. The German luxury carmaker unveiled the Mercedes-Benz GLE L at the 2026 Chengdu Auto Show. Designed specifically with the Chinese luxury SUV market in mind, the new GLE L brings a 120mm longer wheelbase, a spacious cabin, powerful turbo petrol engines and a host of premium comfort and technology features.

The Mercedes-Benz GLE L is expected to be offered in two variants, namely the GLE 350 L 4Matic and GLE 450 L 4Matic. Both versions use turbocharged petrol engines with mild hybrid assistance, a 9 speed automatic transmission and all wheel drive.

The biggest highlight of the new SUV is its extended wheelbase. The additional length creates more room inside the cabin, particularly for rear seat passengers. Mercedes-Benz has also introduced a special Boss Mode that further enhances rear passenger comfort.

Mercedes-Benz GLE L Gets a 120mm Longer Wheelbase

The most important change on the Mercedes-Benz GLE L is its extended wheelbase. Compared with the standard wheelbase GLE, the new long wheelbase model gets an additional 120mm of wheelbase.

The longer wheelbase has been developed primarily to improve interior space. Rear passengers get additional legroom, making the SUV more comfortable for long journeys.

This approach is particularly important in China, where luxury car buyers often place strong emphasis on rear seat comfort and chauffeur driven travel. The GLE L has therefore been designed not just as a larger SUV but as a more premium rear passenger focused vehicle.

Apart from the extended wheelbase and newly designed alloy wheels, the overall exterior styling remains closely related to the standard Mercedes-Benz GLE.

Mercedes-Benz GLE L Introduces a Special Boss Mode

One of the most impressive features of the new Mercedes-Benz GLE L is its Boss Mode. This feature has been developed to provide additional comfort to passengers sitting in the rear.

When activated, the front passenger seat can be tilted forward by up to 10.91 degrees. This creates additional legroom for the rear passenger, allowing them to stretch their legs and enjoy a more relaxed seating position.

Mercedes-Benz says the feature has been inspired by the more expensive Mercedes-Maybach GLS. Bringing such a premium comfort feature to the GLE L gives the SUV a more luxurious and chauffeur friendly character.

For buyers who frequently travel with a driver, the Boss Mode could become one of the most attractive features of the GLE L.

Mercedes-Benz GLE L Engine Options

The new Mercedes-Benz GLE L will be offered with two turbocharged petrol engine options in China. Both engines receive mild hybrid assistance and are paired with a 9 speed automatic transmission.

Mercedes-Benz GLE 350 L 4Matic Engine

The Mercedes-Benz GLE 350 L 4Matic is powered by a 2.0 litre four cylinder turbo petrol engine. It produces 258hp of maximum power and 400Nm of peak torque.

The engine is supported by mild hybrid technology, which is designed to improve efficiency and provide smoother performance. Power is sent to all four wheels through a 9 speed automatic gearbox.

The GLE 350 L is positioned as the more accessible version of the two variants and should appeal to customers looking for a combination of performance, comfort and efficiency.

Mercedes-Benz GLE 450 L 4Matic Engine

The more powerful Mercedes-Benz GLE 450 L 4Matic gets a 3.0 litre turbocharged inline six cylinder petrol engine.

This engine develops an impressive 381hp and 560Nm of peak torque. It is also paired with mild hybrid assistance, a 9 speed automatic transmission and Mercedes-Benz 4Matic all wheel drive.

With significantly more power than the GLE 350 L, the GLE 450 L is expected to deliver stronger acceleration and a more engaging driving experience while retaining the premium comfort expected from a Mercedes-Benz SUV.

4Matic All Wheel Drive Comes as Standard

Both Mercedes-Benz GLE L variants come with the company’s 4Matic all wheel drive system.

The all wheel drive setup helps distribute engine power to the wheels depending on driving conditions. This can provide better traction on slippery surfaces and improve stability during high speed highway driving.

For a luxury SUV with substantial power, the 4Matic system also adds confidence when driving on challenging roads and in varying weather conditions.

Mercedes-Benz GLE L Gets a Premium Exterior Design

The exterior design of the Mercedes-Benz GLE L remains largely similar to the standard wheelbase GLE. However, the longer body gives the SUV a more stretched and imposing road presence.

At the front, the SUV features a glossy black grille surrounded by chrome elements. Multiple three pointed star inspired elements are incorporated into the grille, reinforcing the brand’s signature luxury identity.

Distinctive LED Headlamps

The front lighting setup features dual barrel style LED headlamps with distinctive three pointed star shaped daytime running light elements.

The lighting design gives the GLE L a modern appearance while maintaining its connection with the latest Mercedes-Benz design language.

New alloy wheel designs further differentiate the long wheelbase model. Combined with the extended wheelbase, these wheels give the SUV a substantial and sophisticated side profile.

Premium Rear Styling

The rear design of the Mercedes-Benz GLE L also follows the styling theme of the standard GLE.

It gets wraparound LED tail lamps featuring triangular lighting elements. A black trim element visually connects the rear lighting units, while dual exhaust tips add a sporty touch to the lower section.

Overall, the design remains elegant rather than radically different, allowing the GLE L to retain the recognizable identity of the GLE family.

Mercedes-Benz GLE L Interior Is Loaded With Technology

The interior of the China specification Mercedes-Benz GLE L largely follows the cabin design of the standard wheelbase GLE.

The dashboard features three 12.3 inch displays. One screen serves as the digital instrument cluster, another handles the infotainment system, while a dedicated display is positioned for the front passenger.

This three screen layout gives the cabin a modern and high tech appearance. The separate passenger display also provides additional entertainment and digital functionality for the front passenger.

The SUV also gets a three spoke steering wheel with touch sensitive controls along with physical rocker and roller type switches. This combination provides a blend of digital controls and traditional physical controls.

AI Assistant Adds a Smart Touch

The Mercedes-Benz GLE L also introduces an AI powered assistant for the Chinese market.

The AI assistant is designed to make interaction with the vehicle more convenient by allowing occupants to access various functions and services through intelligent commands.

The introduction of AI technology highlights Mercedes-Benz’s efforts to make its latest vehicles more connected and digitally advanced.

For the Chinese market, where smart vehicle technology has become an increasingly important buying factor, the AI assistant could play a major role in making the GLE L more competitive.

Rear Seat Entertainment Makes the Cabin More Luxurious

Rear passenger comfort is one of the strongest selling points of the Mercedes-Benz GLE L.

In addition to the increased legroom created by the 120mm longer wheelbase, the SUV features new rear seat entertainment screens.

These screens allow rear passengers to enjoy entertainment during long journeys. Combined with the Boss Mode and additional rear seat space, the GLE L offers a more premium rear cabin experience.

The longer wheelbase is therefore not simply a dimensional upgrade. It forms the foundation of Mercedes-Benz’s strategy to transform the GLE L into a more comfortable and luxurious vehicle for rear passengers.

Standard Mercedes-Benz GLE Offers More Powertrain Choices

The standard wheelbase Mercedes-Benz GLE is available with a wider range of powertrain options in some markets.

The lineup includes the GLE 580, which is powered by a 4.0 litre twin turbocharged V8 engine producing around 537hp.

There is also a GLE 450e plug in hybrid model, along with diesel powered versions in selected markets.

However, Mercedes-Benz has currently focused the China specification GLE L lineup on the GLE 350 L 4Matic and GLE 450 L 4Matic variants.

Mercedes-Benz GLE L Could Rival Other Long Wheelbase Luxury SUVs

The Mercedes-Benz GLE L has been developed specifically for a market where rear passenger comfort is a major consideration.

China has a strong demand for long wheelbase luxury vehicles, particularly among customers who value additional cabin space and chauffeur driven comfort.

The GLE L is expected to compete with other premium SUVs offering extended wheelbase versions, including long wheelbase luxury SUVs from BMW and other German manufacturers.

Its combination of a 120mm longer wheelbase, powerful petrol engines, premium cabin technology and rear seat focused features could give it a strong position in this competitive segment.

Will Mercedes-Benz GLE L Launch in India

Mercedes-Benz already sells the GLE SUV in India, making the possibility of a long wheelbase version particularly interesting for Indian luxury SUV buyers.

However, the company has not made any official announcement regarding the launch of the Mercedes-Benz GLE L in India.

If Mercedes-Benz eventually introduces the GLE L to the Indian market, its extended rear legroom and premium rear seat features could make it particularly appealing to chauffeur driven customers.

India has a growing market for luxury SUVs, and premium rear seat comfort is becoming increasingly important among high end buyers. The Boss Mode could also give the GLE L a distinctive advantage over the standard GLE.

Mercedes-Benz GLE L Key Highlights

The new Mercedes-Benz GLE L combines several important upgrades and luxury features.

Its 120mm longer wheelbase creates additional rear cabin space. The special Boss Mode improves rear passenger comfort by moving the front passenger seat forward. The SUV also offers rear entertainment screens, an AI assistant and a three screen dashboard layout.

Under the bonnet, customers can choose between a 2.0 litre turbo petrol engine producing 258hp and a 3.0 litre inline six turbo petrol engine producing 381hp.

Both versions receive mild hybrid assistance, a 9 speed automatic transmission and 4Matic all wheel drive.

Conclusion

The Mercedes-Benz GLE L represents a major evolution of the GLE for the Chinese luxury SUV market. Instead of simply increasing the exterior dimensions, Mercedes-Benz has used the additional 120mm wheelbase to create a more spacious and luxurious rear passenger environment.

The powerful 258hp GLE 350 L and 381hp GLE 450 L provide strong performance, while mild hybrid technology, a 9 speed automatic transmission and 4Matic all wheel drive add refinement and versatility.

The Boss Mode, rear entertainment screens, AI assistant and three 12.3 inch displays further strengthen the SUV’s premium appeal.

For now, the Mercedes-Benz GLE L has been introduced for the Chinese market, and there is no official confirmation regarding its launch in India. If Mercedes-Benz eventually brings this long wheelbase SUV to India, its combination of powerful engines, impressive technology and exceptional rear seat comfort could make it a highly desirable premium SUV.
