Mercedes-Benz SUV Range Explained: Which Model Is Right for You?

Thinking about getting a Mercedes-Benz SUV but not sure where to start? We get it. With so many models, it can be tricky to tell your GLAs from your GLCs. Don’t worry, we’re here to help you figure out the differences and find the perfect one for you.

This guide will walk you through the entire Mercedes-Benz SUV range. We’ll look at everything from the compact GLA to the huge GLS, and even touch on the iconic G-Class. Let's find your next ride.

What is the smallest Mercedes-Benz SUV?

If you're after something compact but still packed with luxury, the Mercedes-Benz GLA is a fantastic choice. It's similar in size to a Nissan Qashqai but gives you that premium feel, plus a higher seating position than the Mercedes A-Class hatchback. It's a versatile car that's just as happy on city streets as it is on a weekend adventure. A new, third-generation GLA arrived in 2026, and it's a bit of a landmark car for Mercedes: rather than selling a separate electric model alongside it, the new GLA is offered with petrol, mild-hybrid and fully electric power all under the same name. That means the old all-electric EQA has now been retired – if you're shopping used, an EQA is simply an older, electric GLA in all but badge.

Need a bit more room but don't want a massive SUV? Check out the GLB. It's a clever one because it manages to fit seven seats into a relatively compact body. It's a great option if you only need those extra seats every now and then. The GLB is following the same path as the GLA: the standalone electric EQB has been discontinued, and an electric GLB has taken its place within the regular GLB range.

What is the largest Mercedes-Benz SUV?

At the other end of the scale is the Mercedes-Benz GLS, the biggest SUV in the lineup. It's a massive 5.2 metres long, which gives it more space than most other SUVs out there, including the long-wheelbase Range Rover. This is the one for you if you want maximum space and luxury, with seven proper seats and a huge boot.

If you want an electric drive with plenty of space, the all-electric Mercedes-Benz EQS SUV is another brilliant option. It's a little shorter than the GLS but still offers a seriously luxurious electric experience. There's also an ultra-luxurious Mercedes-Maybach version of both the GLS and the EQS SUV, if you want the last word in comfort.

Stepping down a size, the Mercedes-Benz GLE is perfect for families who need lots of room but don't fancy driving something quite as big as the GLS. Another popular model is the Mercedes-Benz GLC, which is about the same size as a Volvo XC60 and is one of the best Mercedes SUVs for all-round use. The GLC has recently gained its own electric version too, badged as the GLC with EQ Technology, sitting alongside the existing petrol and hybrid GLC and GLC Coupé models.

What makes the G-Class so special?

The Mercedes-Benz G-Class is a true one-off. It first appeared way back in 1979 and has become an icon over the years. Size-wise, it sits between the GLC and GLE, but it costs a lot more. That's down to its super-tough build, cool retro styling, and incredible performance. The G-Class has now gone electric too, with the G 580 with EQ Technology sitting alongside the familiar petrol models. It keeps the boxy retro looks and is, if anything, even more capable off-road thanks to a four-motor set-up that can control each wheel individually – though it's worth knowing its towing ability isn't a match for the combustion G-Class (more on that below).

Which Mercedes SUV is best for dog owners?

Good news for dog lovers! Every Mercedes-Benz SUV has a good-sized boot, so you'll find one to suit your furry friend, no matter how big they are. The GLA's boot is plenty big enough for a Jack Russell, and a St. Bernard would be more than happy in the back of a GLS.

But what if you have a larger dog, like a Labrador, but don't want a huge car? The GLB could be perfect for you and your pooch. It has a very big boot for its relatively compact size.

Which Mercedes SUV models have seven seats?

If you need to carry a bigger crew, three Mercedes-Benz SUV models offer seven seats: the GLB, GLE, and GLS. The third-row seats in the GLB and GLE are best for children or for adults on shorter trips. For maximum comfort, the GLS offers loads of space for adults, even on long journeys.

Are there electric or hybrid Mercedes SUVs?

Yes, Mercedes-Benz is all-in on electric and hybrid tech, and the range has changed a lot recently. Plug-in hybrid versions remain available on the GLA, GLC and GLE, and the GLC, GLE and GLS all use mild-hybrid 'EQ-Boost' technology to help improve fuel efficiency.

Mercedes is also moving away from giving its fully electric models separate 'EQ' names, and instead folding electric power into the existing model range. Here's where things stand:

• GLA: now offered as a fully electric model alongside petrol and hybrid versions, replacing the old standalone EQA.
• GLB: gaining its own electric version, replacing the discontinued EQB.
• GLC: available as the GLC with EQ Technology, alongside the regular petrol and hybrid GLC.
• G-Class: available fully electric as the G 580 with EQ Technology, alongside the classic petrol version.
• EQS SUV: still Mercedes' standalone flagship electric SUV, including a Mercedes-Maybach version.

The EQC has been discontinued since 2023, and the EQE SUV is also being phased out as Mercedes streamlines the range – so if you spot either of these, they'll be used cars rather than something you can order new, but that doesn't make them any less capable to buy second-hand.

Our guide to hybrid, mild hybrid and plug-in hybrid cars explains the differences in more detail if you're deciding which type suits you.

Which Mercedes SUV has the biggest boot?

Need loads of storage? The Mercedes-Benz GLS is the winner here. Even with all seven seats in use, it offers 355 litres of space. Fold down the third row, and you get a massive 890 litres – enough to fit a washing machine. If the GLS is a bit too big for you, the GLE and GLB also have impressive boots, making them great luxury SUVs for families.

Are Mercedes SUVs good off-road?

While most Mercedes-Benz SUVs are designed for comfort on the road, models like the GLC, GLE, and GLS are still pretty capable when the tarmac ends. However, if you're looking for the ultimate off-road experience, the G-Class is the one to go for. It's built to handle the toughest terrain, and even the new electric version holds up its end – its four individually controlled motors and deep wading ability mean it's every bit as capable off-road as the combustion model, if not more so.

Do all Mercedes SUVs have four-wheel drive?

Most Mercedes-Benz SUVs come with four-wheel drive, which you'll see badged as '4MATIC'. However, some lower-powered versions of the GLA and GLB are front-wheel drive, which makes them a bit more economical for town driving.

Which Mercedes SUV is best for towing?

Most Mercedes-Benz SUVs are great for towing. The GLA can pull between 1,400-1,800kg, while the GLB can manage 1,800-2,000kg. The GLC, GLE, and GLS can all tow at least 2,000kg. For really heavy-duty jobs, certain GLE models and the petrol and diesel G-Class can tow up to 3,500kg.

It's worth being aware that the electric models generally tow less than their petrol or diesel equivalents: the EQS SUV, for example, is rated to tow around 1,800kg, and the electric G-Class can't tow anything at all. If towing is a priority, it's well worth checking the exact figure for the specific model and engine you're looking at.

Are there sporty Mercedes SUV models?

Absolutely. If you love performance, Mercedes-AMG offers sporty versions of almost every SUV in the range (except the electric ones). These high-performance models are faster and have sharper handling. For example, the Mercedes-AMG GLE 63 is a big step up in power from the GLE 53. If you want speed and style, the AMG range has you covered.

In Summary: The Core Mercedes-Benz SUV Range

• Mercedes-Benz GLA: The most compact Mercedes SUV and a popular family car. Now in its third generation, offered with petrol, hybrid or fully electric power under one name – the older, separate EQA electric model has been retired.
• Mercedes-Benz GLB: One of the most compact seven-seat SUVs you can get. A great choice for growing families, now also available as an electric model, replacing the discontinued EQB.
• Mercedes-Benz GLC: The most popular Mercedes SUV. It offers luxury and tech in a practical mid-size package, available as an SUV or a sleeker Coupe, and now as the fully electric GLC with EQ Technology too.
• Mercedes-Benz GLE: A large SUV that's great for big families who want luxury and tech. Also available as an SUV or Coupe.
• Mercedes-Benz GLS: The biggest Mercedes SUV, offering limo-like space and comfort for seven people, with an ultra-luxurious Mercedes-Maybach version at the very top of the range.
• Mercedes-Benz G-Class: The top-of-the-range icon. Its appeal lies in its retro design, luxurious interior, and incredible off-road ability, now available as a fully electric model alongside the classic petrol version.
• Mercedes-Benz EQS SUV: Mercedes' standalone flagship electric SUV, sitting apart from the core range, with a Mercedes-Maybach version for maximum luxury.

A few older electric models are worth knowing about if you're buying used: the EQA and EQB have both been replaced by electric versions of the GLA and GLB, the EQC was discontinued back in 2023, and the EQE SUV is gradually being phased out. None of that makes them bad used buys – it just means you won't find them on sale new any more.
