Best Mercedes-Benz GLE Generations (Ranked) in 2027

1. W166 GLE (2015-2019)

The W166 GLE is the best overall GLE because it combines the proven W166 platform with the 9G-TRONIC nine-speed automatic and refined COMAND infotainment, arriving after early teething issues were resolved. The volume GLE 350 uses a 3.5-liter naturally aspirated V6 making 302 horsepower, while the GLE 400's 3.0-liter biturbo V6 delivers 329 horsepower. Base cars with steel-spring suspension avoid costly AIRMATIC repairs, making this the most reliable GLE generation.

This is the safest all-around buy for anyone wanting modern comfort with proven dependability. It trades the W167's cutting-edge tech and 48-volt systems for simpler, cheaper-to-fix hardware. Compared to the W167 below it, the W166 is far less complex and expensive to maintain out of warranty, while still offering ample luxury and performance. It is the strongest pick for a daily driver who values low ownership costs.

2. W167 GLE (2019-present)

The W167 GLE ranks second because it is the most advanced and luxurious GLE ever built, introducing the MHEV 48-volt mild-hybrid system on its inline-six engines. The GLE 450 pairs a 3.0-liter turbocharged inline-six (M256) with EQ Boost for 362 horsepower, plus a brief electric torque fill that erases turbo lag. Optional E-ACTIVE BODY CONTROL air suspension delivers the best ride in the class, and the dual 12.3-inch MBUX screens set interior benchmarks.

This generation is for buyers who want the latest technology and maximum luxury and are willing to accept steep out-of-warranty repair costs. It trades long-term affordability for cutting-edge features, with 48-volt electronics, air suspension, and a dense sensor suite posing significant financial risks. Compared to the W166 above it, the W167 is more refined and capable but far more expensive to maintain. Low-mileage GLE 450 examples are the smart pick here.

3. Mercedes-AMG GLE 63 S (M177 V8)

The AMG GLE 63 S ranks third as the most ferocious GLE ever sold, using the hand-built M177 4.0-liter twin-turbo V8 producing 577 horsepower and 561 lb-ft of torque in S trim. The W167 version adds EQ Boost for short bursts, enabling zero to sixty in roughly 3.7 seconds, absurd for a two-and-a-half-ton SUV. The earlier W166 GLE 63 S used the M157 5.5-liter biturbo V8 at the same 577 horsepower.

This is for performance enthusiasts who demand supercar acceleration in an SUV and accept brutal running costs. It trades fuel economy, tire life, brake wear, and repair affordability for sheer power and drama. Compared to the GLE 53 below it, the 63 S is far more expensive to feed and maintain, with any V8 repair costing a fortune. It is a weekend toy or statement vehicle, not a sensible daily driver.

4. W164 ML350 (2005-2011)

The W164 ML350 ranks fourth as the smartest budget buy in the entire GLE lineage, offering the best value per dollar. Its 3.5-liter V6 (M272) makes 268 horsepower, paired with a smooth 7G-TRONIC seven-speed automatic, and most examples ride on conventional steel springs, sidestepping AIRMATIC repair bills. The 4MATIC all-wheel-drive system is genuinely capable, and parts are cheap and abundant after two decades of production.

This car is for budget-conscious buyers who want a comfortable, capable luxury SUV and can accept its age. It trades modern infotainment and safety tech for rock-bottom pricing and sane maintenance costs. Compared to the W166 GLE above it, the W164 is older and less refined but dramatically cheaper to buy and run. Watch for the M272 balance-shaft issue on early build dates and rust in salt-belt cars.

5. W166 GLE 350d / ML Diesel (OM642)

The diesel GLE 350d and its ML250/ML350 BlueTEC predecessors rank fifth as the long-haul value play, thanks to the OM642 3.0-liter turbo-diesel V6. It produces around 255 horsepower but a stout 457 lb-ft of torque, hauling the GLE effortlessly while returning 28 to 32 mpg on the highway, figures no gasoline GLE approaches. For towing and big-mileage driving, nothing in the range is cheaper to feed.

This is for high-mileage drivers and towers who prioritize fuel economy and torque over refinement. It trades the gasoline engines' smoothness for diesel clatter and emissions-system complexity, including AdBlue, DPF, and injector costs. Compared to the AMG GLE 63 S above it, the diesel is far cheaper to run but lacks any performance thrill. Documented service history is the single most important factor in any purchase decision.

6. Mercedes-AMG GLE 53 (M256)

The AMG GLE 53 ranks sixth because it splits the difference between the comfort-focused GLE 450 and the brutal GLE 63, offering genuine AMG performance with sane running costs. It uses the same 3.0-liter turbocharged inline-six (M256) as the 450 but tuned to 429 horsepower, with 48-volt EQ Boost adding a momentary 21 horsepower. An electric auxiliary compressor makes throttle response immediate, and zero to sixty takes about 5.2 seconds.

This is for buyers who want AMG styling, suspension, and brakes without the V8's fuel and repair bills. It trades the 63 S's raw power for better fuel economy and lower running costs, though the 48-volt and turbo hardware can be pricey out of warranty. Compared to the diesel above it, the GLE 53 is far more exciting but less efficient and more expensive to maintain. It is the sweet spot for a performance-oriented daily driver.

7. W166 GLE Coupe (C292)

The GLE Coupe (C292) ranks seventh because it brings a fastback roofline to the W166 platform, chasing the BMW X6 for buyers who prioritize style over practicality. Engine choices mirror the regular GLE, from the GLE 350d diesel to the GLE 400's 3.0-liter biturbo V6 at 329 horsepower, up to the GLE 63 S Coupe's M157 5.5-liter biturbo V8 at 577 horsepower.

This is for style-driven buyers who accept compromised practicality for a sleeker silhouette. It trades rear headroom, cargo space, and air-suspension reliability for distinctive looks. Compared to the GLE 53 above it, the Coupe is less practical and often less reliable, but a clean GLE 43 or GLE 400 Coupe offers strong looks and pace for the money. It ranks mid-pack because the compromises are real.

8. W166 M-Class (2011-2015)

The W166 M-Class ranks eighth because it laid the groundwork for the strong GLE, introducing a stiffer body, improved efficiency, and turbocharged engines. The ML350 ran a 3.5-liter V6 at 302 horsepower, while the ML550 packed a 4.6-liter biturbo V8 (M278) making 402 horsepower. Diesel ML250/ML350 BlueTEC variants used the OM642 for excellent economy, and mechanically it is nearly identical to the early GLE.

This is for buyers who want GLE substance at a discount, accepting the older infotainment and pre-facelift styling. It trades the renamed GLE's modern tech and looks for a meaningful price cut, undercutting the badge-equivalent car by a significant margin. Compared to the GLE Coupe above it, the M-Class is more practical and cheaper, though less stylish. It is a savvy choice for those who prioritize value over the latest features.

9. ML 55 AMG (W163, 2000-2003)

The ML 55 AMG ranks ninth as the cult classic of the family and the first AMG-fettled M-Class, earning its spot on collectibility and engine durability. It crammed a hand-assembled 5.4-liter naturally aspirated V8 (M113) making 342 horsepower and 376 lb-ft of torque into the rugged W163 body, paired with a five-speed automatic and full-time 4MATIC. At launch it was among the quickest SUVs on Earth, hitting sixty in around 6.5 seconds.

This is for collectors and enthusiasts who value analog character and engine durability over everyday usability. It trades W163-era build quality, dated electronics, rust, and thirsty fuel consumption for genuine charm and rarity. Compared to the W166 M-Class above it, the ML 55 is far less practical and reliable but more collectible. It ranks here on historical significance rather than as a sensible daily driver.

10. W163 M-Class (1997-2005)

The W163 M-Class ranks tenth because it is where it all began, earning its spot on historical significance and dirt-cheap entry pricing. As the first Mercedes SUV, it offered genuine off-road ability with a two-speed transfer case and locking differentials, wrapped in a then-novel luxury package. Engines ranged from the ML320's 3.2-liter V6 at 215 horsepower to the ML430 and ML500's 5.0-liter V8 near 288 horsepower.

This is strictly a project or beater buy for someone who wants cheap off-road capability and does the wrenching themselves. It trades modern comfort, reliability, and safety for the lowest possible entry price and genuine off-road chops. Compared to the ML 55 AMG above it, the standard W163 is less collectible and even more fragile, but also cheaper. It is a risky purchase best left to enthusiasts with time and tools.

How we ranked these

This ranking weighs reliability, performance, real-world running costs, and 2026 used-market value. Reliability and cost of ownership are weighted most heavily, as they determine long-term satisfaction and financial risk. Performance and luxury features are considered but secondary, given the GLE's role as a family hauler. Each generation is scored on its known failure points, parts availability, and typical repair expenses.

Deliberately ignored were subjective styling preferences and brand prestige, as these vary by buyer and do not reflect objective quality. Also excluded were dealer incentives and new-car pricing, since the focus is on used purchases. Historical significance and collectibility were only minor factors, as they do not impact the daily ownership experience for most buyers. The goal is to identify the most sensible, reliable, and cost-effective choices.

What to look for

When choosing between GLE generations, the critical factors are suspension type, service history, and engine condition. Steel-spring cars are far cheaper to maintain than air-suspension models, which can cost $1,500+ per corner to replace. A documented service history is non-negotiable, as deferred maintenance on German luxury SUVs leads to expensive failures. Prioritize a pre-purchase inspection focusing on air suspension, transmission, electronics, and rust, especially on W163 and W164 models.

The biggest mistake buyers make is chasing the lowest purchase price or the most loaded feature list, ignoring maintenance records. A cheap GLE with neglected service can quickly become a money pit, with repairs exceeding the car's value. Conversely, a slightly more expensive example with full service history is a far better investment. Always buy the best-maintained car you can afford, not the flashiest or cheapest one.

Related questions

What is the most reliable Mercedes-Benz GLE generation?

The W166 GLE (2015-2019) is widely considered the most reliable generation. It benefits from years of refinement on the W164 platform, with fewer major issues like balance-shaft failures or air suspension leaks compared to earlier models. That said, even this generation can have occasional electrical glitches, so a well-maintained example is key.

Which GLE generation should I avoid buying used?

The W164 M-Class (2006-2011) is the most problematic. It suffers from balance-shaft wear in V6 engines, premature suspension component failures, and rust-prone rear subframes. Repair costs can quickly exceed the car’s value, making it a risky choice unless you have a documented service history.

How much does it cost to maintain an older Mercedes GLE?

Annual maintenance for a W163 (1997-2005) ranges from roughly $1,500 to $3,000, depending on condition and mileage. Newer W166 and W167 models typically cost $1,000 to $2,500 per year for routine service, but major repairs like air suspension or transmission work can add $2,000–$5,000 unexpectedly.

Is the GLE good for off-roading?

Early W163 models with the optional low-range transfer case and locking differentials are genuinely capable off-road.

What is the fuel economy like across GLE generations?

Real-world combined MPG ranges from about 14–16 for V8 AMG models to 20–24 for diesel or four-cylinder variants. The W166 GLE350 with the V6 averages 18–20 MPG, while the W167 with the 48-volt mild hybrid straight-six can reach 21–23 MPG. Towing or city driving drops these numbers by 2–4 MPG.

Are AMG GLE models reliable for daily driving?

AMG models, especially the W166 GLE63 (2015-2019), are generally reliable if serviced properly. Their twin-turbo V8s are robust, but they demand more frequent oil changes and brake replacements. Running costs are higher—expect $2,500–$4,000 annually for maintenance and fuel—but they offer exceptional performance for a daily driver.

FAQ

What is the best Mercedes-Benz GLE generation overall?

The W166 GLE (2015-2019) is the best overall. It combines the proven W166 platform with the GLE-era refinements, including the 9G-TRONIC transmission and updated COMAND system. Reliability is the best of any GLE, and steel-spring base models avoid costly air suspension repairs. Prices range from $18,000 to $30,000 in 2026.

Which GLE generation offers the best value for money?

The W164 ML350 (2005-2011) is the value champion. With prices between $5,000 and $10,000, it delivers a comfortable, capable luxury SUV with a durable 3.5-liter V6 and conventional steel springs. Watch for the M272 balance-shaft issue on early builds and rust in salt-belt cars, but otherwise it's a smart budget buy.

What are the common problems with the W167 GLE?

The W167 GLE (2019-present) has complex 48-volt electronics, air suspension, and a dense sensor suite that can be expensive to repair out of warranty. The E-ACTIVE BODY CONTROL system is particularly costly to fix. However, the M256 inline-six engine is generally reliable, and low-mileage GLE 450 examples are the smartest pick.

How does the GLE 53 compare to the GLE 63?

The GLE 53 uses a 3.0-liter turbo inline-six with 429 horsepower and 48-volt EQ Boost, offering strong performance with better fuel economy and lower running costs.

Choose the 53 for daily usability, the 63 for maximum performance.

Is the GLE Coupe a good used buy?

The GLE Coupe (C292) offers style but sacrifices rear headroom and cargo space. It ranks mid-pack due to these compromises and standard air suspension on many trims. However, softer resale values make it a good used deal, especially for the GLE 43 or GLE 400 Coupe, with prices from $28,000 to $50,000.

What should I look for when buying a used GLE 350d?

For a used GLE 350d, the most important factor is a documented service history, especially for the AdBlue system, DPF, and injectors. These components can be costly to replace if neglected. Well-maintained examples can exceed 200,000 miles, but emissions-related repairs can be expensive, so a pre-purchase inspection is essential.

Are W163 M-Class models worth buying in 2026?

The W163 M-Class is a project or beater buy, with prices from $2,000 to $6,000. It offers genuine off-road capability and a rugged design, but build quality and electronics are weak, and rust is common. It's best for someone who can do their own wrenching and wants cheap off-road capability, not a daily driver.
