First Drive: 2023 Mercedes GLE – Evolution Over Revolution

The updated Mercedes GLE for 2023, available in both SUV and coupé configurations, subtly refines its predecessor’s formula rather than reinventing it. This approach aligns with Mercedes’ strategy, as the fourth-generation GLE continues to enjoy robust sales five years after its debut.

Exterior Tweaks for a Fresh Look

At first glance, the differences between the facelifted GLE and its predecessor may seem minimal – and that’s intentional. The exterior updates include a redesigned front bumper, a tweaked grille, and refreshed LED graphics for the headlights and tail-lights. Additionally, new wheel designs are offered, ranging up to an impressive 22 inches in size.

Buyers can choose from three trim levels for the SUV: AMG Line, AMG Line Premium, and AMG Premium Plus. The coupé version, however, is only available in the top-tier AMG Premium Plus trim.

Enhanced Interior and Advanced Tech

Inside, the GLE benefits from several modern updates, including Mercedes’ latest multi-function steering wheel and an upgraded MBUX operating system. The system boasts enhanced software and more intuitive menus. For models equipped with the optional Off-Road Package, new graphics complement the standard 360-degree camera.

The cabin maintains its reputation for spaciousness and premium materials, offering ample room for passengers in both the front and rear seats. However, the plug-in hybrid model sacrifices some boot capacity due to the battery placement, reducing storage from 630 litres in standard versions to 490 litres.

A Versatile Engine Line-Up

The GLE offers a wide range of seven drivetrain options, starting with the 266bhp 3.0-litre inline-six diesel engine in the GLE 300d 4Matic and culminating in the high-performance 603bhp 4.0-litre V8 petrol engine in the GLE 63 4Matic+.

All internal combustion engine (ICE) models now incorporate a 48V electrical architecture with an integrated starter motor, delivering a boost in power and torque during acceleration while also enhancing fuel efficiency with a coasting function.

The GLE 400e 4Matic, one of two plug-in hybrid electric vehicles (PHEVs) in the line-up, pairs a 2.0-litre turbocharged four-cylinder petrol engine with an electric motor for a combined output of 375bhp – a 40bhp increase over its predecessor – and 443lb ft of torque. Powering this system is a 31.2kWh lithium-ion battery, which supports charging rates of up to 11kW on AC and 60kW on DC systems.

Driving Dynamics and Comfort

While the GLE 400e retains the standard steel suspension, the test model featured the optional Airmatic system, which ensures a controlled and smooth ride. Even with optional 20-inch wheels, the suspension manages to deliver excellent refinement, absorbing road imperfections with ease.

On electric power alone, the GLE offers a commendable driving experience, moving almost silently through urban environments. Although its real-world electric range falls short of the official WLTP estimate of 57-65 miles, it still surpasses many hybrid competitors in this regard.

Performance in mixed driving is robust. The vehicle feels responsive and agile in town, with strong acceleration from a standstill. However, when the petrol engine engages, particularly at higher revs or in lower gears, it can become noticeably vocal. That said, the system remains smooth and composed on motorways, where the interplay between the petrol engine and electric motor is seamless.

Handling and Refinement

Despite its size, the GLE 400e is easy to manoeuvre thanks to light yet precise steering. The 4Matic all-wheel-drive system provides excellent traction, while the suspension strikes a balance between comfort and control. Body roll is well-managed, though the additional weight of the battery becomes evident during rapid directional changes.

The suspension effectively handles larger bumps, maintaining stability without harshness. Noise levels, including road roar, are well-isolated, contributing to the overall refinement of the ride.

Conclusion: A Strong Plug-In Hybrid Contender

The GLE 400e 4Matic positions itself as a compelling choice for those seeking a premium SUV with a respectable electric range for urban use. While its starting price of £87,500 places it in competition with other high-end plug-in hybrid SUVs, it offers a solid balance of luxury, technology, and efficiency.

For buyers who value electric capability alongside the versatility of a traditional SUV, the GLE 400e proves to be a worthy contender in its class
