Mercedes GLB SUV

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?

Mercedes GLA

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.

There’s also an all-electric version called the EQA. It keeps all the fancy bits of the GLA but with the bonus of an eco-friendly electric drive.

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.

What is the largest Mercedes-Benz SUV?

Mercedes GLE

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.

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.

What makes the G-Class so special?

Mercedes G-Class

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.

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. You can get plug-in hybrid versions of the GLA, GLC, and GLE. On top of that, the GLC, GLE, and GLS models feature mild-hybrid technology (called ‘EQ-Boost’) to help improve fuel efficiency.

For pure electric options, Mercedes offers the EQA, EQB, EQC, EQE, and EQS. The EQA and EQB are the electric sisters of the GLA and GLB, while the others are standalone electric models.

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.

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?

All 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 all GLS and G-Class models can tow up to 3,500kg.

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.
