Here are the differences between the ML400 and GLE400: 1. Exterior: The Mercedes-Benz ML400 adopts a black-and-white color scheme that doesn't appear abrupt, especially with its RS9 lightweight aluminum alloy wheels in a mysterious black hue, which naturally draws attention to this set of 22-inch wheels. The most distinctive feature of this configuration is the five-spoke wheel center paired with dual-groove wheel spokes. The GLE400 utilizes Mercedes-Benz's latest family-style front fascia design, featuring a double-slat grille with a large-sized logo, and its front bumper design is quite stylish and sporty. 2. Powertrain: The Mercedes-Benz ML400 is equipped with V6 and V8 engines ranging from 190 horsepower to 388 horsepower. The GLE400 is powered by a 3.0L twin-turbocharged engine paired with a 9-speed automatic transmission.

















The ML400 and GLE400 are essentially different generations of the same model. The ML400 was the older naming used from 2011 to 2015. I once drove a friend's ML400, and its chassis tuning was on the firmer side, with a traditional interior featuring mechanical instrument clusters and physical buttons. When it was updated to the GLE400, not only did the name change, but the design was completely upgraded. For instance, during my test drive, I loved the dual large screens—their touch response was incredibly fast, and the voice-controlled air conditioning was super convenient. The optimized suspension made driving over speed bumps much more comfortable. Although both models have a 3.0T engine, the GLE400’s fuel consumption dropped by about 1 liter. In the current used car market, the ML400 is about 50,000 to 60,000 RMB cheaper, but its infotainment system is outdated, lacking even CarPlay. For younger buyers, the GLE400 is definitely the more suitable choice.

The main differences between these two models lie in their generational updates. As someone working in automotive media, I can tell you that before 2015, called this model the ML-Class. The ML400 featured more squared-off LED headlight designs and thinner rear seat cushions. The mid-cycle refresh in 2015 upgraded it to the GLE400, which adopted a starry sky grille with AMG styling package, giving it a much sportier look. The interior space is largely similar, but the GLE400 adds power-adjustable thigh support. Safety saw significant improvements—the new model comes standard with autonomous emergency braking and blind spot monitoring, while the older version even had unclear reversing camera images. Both powertrains are reliable, but the GLE's 9-speed automatic transmission shifts more smoothly, whereas the older 7-speed occasionally exhibits jerky shifts. If your budget allows, I'd recommend going straight for the newer model.

The ML400 and GLE400 are essentially from different generations. In my ten years as a mechanic, I've seen many ML400s with messy pipeline layouts in the engine bay—changing spark plugs requires removing half the engine cover. The GLE400 has optimized its structure, making much easier. The older model's interior had a heavy plastic feel, and my clients often complained about rattling noises. The new model uses soft-touch materials, and the center console features a touchpad that feels like using a tablet. The tire size has also been upgraded from 19 inches to 20 inches. In terms of handling, the GLE's steering is 15% lighter, making city driving less tiring. The fuel consumption difference is less than 1 liter. The key difference is in the resale value: a 2015 ML400 tops out at 250,000 yuan, while a same-year GLE400 is about 80,000 yuan more expensive. Choose the older model for durability, or go for the newer one for comfort.

From a veteran driver's perspective, the biggest difference lies in the tech features. The ML400 is like a Nokia - basic functions are adequate but lack highlights. I once drove it long-distance and even the cruise control required manually twisting a knob. The GLE400 is practically a smartphone - the HUD display eliminates the need to glance down at the dashboard, and the automatic parking is beginner-friendly. Ventilated/heated seats come standard, whereas they're optional on the ML400. The audio system shows the most dramatic gap - the old speakers sounded like a radio, while the new model comes with 13 Burmester speakers. Body rigidity improved by 20%. Having seen accident vehicles, the GLE's A-pillar barely deforms. For buyers, I recommend post-2018 GLE400 models - they're the hottest commodities in the market.

From a family perspective, the differences are quite substantial. The ML400 has shorter rear seat cushions - my mother-in-law complains of back pain after just two hours of sitting. The GLE400 has a 3cm longer wheelbase, and its second-row seats feature adjustable recline angles. Storage space is improved in the newer model with a hollowed-out design under the center console, making it easy to stash my wife's handbag. For families with children, note that the older model's ISOFIX anchors are deeply recessed, while the new version has them readily accessible. The GLE400 comes with PM2.5 filtration for its cabin air filter, eliminating worries about opening windows on hazy days. costs are similar, with minor services costing just over a thousand yuan. Most crucially, the resale value differs significantly: after five years, the ML400 retains only 40% of its value, while the GLE maintains over 55%. For family use, choosing the newer model is undoubtedly the smarter choice.
