Rating: 50.0

Summary

The Mercedes-Benz G-Class may be a luxury SUV but it is also a proper, tough 4×4, its makers dubbing it “stronger than time.”

It was developed as a military vehicle in the 1970s, the first passenger version revealed in 1979 and in those days very spartan. Mercedes turned it into a luxury vehicle in 1990, and the current second generation launched in 2019 – still with its body on a box-section frame for going far off-road in comfort.

“This is no mere posing machine” says Parkers, pointing to the three lockable differentials and low-range transfer gearbox, while adding that such ability comes at a cost. There are only two engine options, a 3.0-litre 326hp diesel or the outrageous AMG petrol of 577hp and a purchase price above £150,000. A 420hp petrol variant is rumoured, but not around yet.

Testers praise the levels of luxury inside the G-Class, and the extensive equipment. “All models come fully loaded,” says Motors.co.uk, highlighting 20-inch alloy wheels, LED headlights, keyless entry, mood lighting and climate control, plus two 12-inch display screens with Apple CarPlay and Android Auto as standard.

But where the latest G-Class has really scored is on its driveability. Compared to its predecessor, Top Gear calls it “a revelation”, adding that the ride, steering and drive are on another level, even before you take it off the road.

Finally, while everything about the G-Class screams expense, Motors points out that it’s so desirable that when you come to sell it, you will get more money than usual back.

As of August 2026, the Mercedes-Benz G-Class holds a New Car Expert Rating of E, with a score of 50%. Inevitably, the big G-Class scores poorly for running costs and CO₂ emissions, while media review scores have only been average. But this is not a car that anyone buys for logical reasons, so a poor score from us is unlikely to hurt sales…

Featured reviews

“For years, the Mercedes-Benz G-Class has been a car that is far more about its image than day-to-day usability. A mild-hybrid powertrain and a great infotainment system don’t change that much. The G-Class is a niche purchase in the UK, and most will be found parked on the trendy streets of central London. But exclusivity is guaranteed and you’ll turn as many heads as in a supercar.”

“The Mercedes G-Class is one of the most recognisable cars on – or indeed off – the road, and this latest model is more luxurious than ever, but other large SUVs are better to drive.”

“Although it’s still a pricey machine, few can match the diesel Mercedes-Benz G-Class’s personality; it’s unique in the large SUV market, and that’s almost worth the entry price alone.” (Sean Carson)

“The W463 Mercedes-Benz G-Class that appeared in 2018 upped the levels of luxury and performance significantly, and despite its rather traditional, almost agricultural looks, it’s a very upmarket, expensive car, especially in top-spec AMG G63 form.” (Sam Naylor)

“You might struggle to tell the difference between the latest Mercedes-Benz G-Class and its predecessor. But as the saying goes, if it ain’t broke, don’t fix it – and as a result, the latest G-Class offers the same style, presence, and the sheer likeability that made the model an icon in the first place.”

“Is the Mercedes-Benz G500 worth the ludicrous price tag that puts even its top-end rivals to shame? To be honest, if you’re willing to dive into the insane world of premium SUVs at all – yes, I reckon it is.”

“It’s an imposing-looking SUV in a Tonka-esque way, but there’s not as much room as you might expect considering its growth compared with its predecessor. Up front it’s snug, but not unpleasantly so, but three adults abreast the back seat will have to be exceptionally good friends.”

“The Mercedes-Benz G-Class is a beast. Though I wager few will do any serious off-roading in this 4X4, the potential is there with three separate differential locks and settings for sand, trail and rock.”

“The sheer strength and bullishness of this car is one of its great attractions. But, in the intervening years since it was only a gleam in the Mercedes eye, its innards have changed – quite radically. What was once the kind of hardcore interior is now extremely plush.”

“The G-Class is an icon that Mercedes-Benz could have ruined with its clean sheet re-engineering and re-design for 2018, but it didn’t. It is an incredible vehicle, looking to all intents and purposes like the car that preceded it for many decades, but being all new. It now drives properly, yet it retains all the appeal of its predecessor. We want one.”

Safety rating

Independent crash test and safety ratings from Euro NCAP

Overall score: 5 stars
Date tested: February 2019
Date expired: January 2026
Read the full Euro NCAP review

Adult protection: 90%
Child protection: 83%
Vulnerable road users: 78%
Safety assist: 72%

The Mercedes-Benz G-Class was tested by Euro NCAP back in 2019 and awarded a five-star rating. However, this rating expired in January 2026 and is no longer valid as the car no longer meets the standards required for such a rating. This is normal practice, as Euro NCAP reviews its ratings on most cars annually with most ratings expiring after about six or seven years.

Although the rating has now expired, the score is still useful if you are comparing a used G-Class to other vehicles of similar age – whose ratings will have probably also expired.

Eco rating

Independent economy and emissions ratings from Green NCAP

No eco rating

As of August 2025, the Mercedes-Benz G-Class has not been assessed by Green NCAP. But it’s a 2.5-tonne SUV with either a big diesel or massive petrol engine, so it’s only slightly more eco-friendly than a coal-fired power station on wheels.

If the G-Class is selected for assessment, we’ll publish the results here.

As you might expect, the Mercedes-Benz G-Class is certainly not cheap to run, according to data exclusively provided by our commercial partner Clear Vehicle Data.

With an average fuel consumption of 25 mpg, the economy of petrol models is terrible, and diesel models are not much better. Emissions are high, service and maintenance costs over the course of five years of ownership are quite expensive, and the SUV’s insurance premiums are some of the highest on the market.

If you’re looking at the Mercedes-Benz G-Class, you might also be interested in these alternatives

There are lots of luxury SUVs around, but step off-road, and the G-Class will eat most of them for breakfast. Few rivals can combine its off-road ability and its plushness. The likes of the Land Rover Defender or the Toyota Land Cruiser might do the off-road bit, while the Bentley Bentayga, Porsche Cayenne or Range Rover tick the luxury box.

But for the best mix of both, the G-Class has few rivals – so long as you can bear its huge costs.
