Currently reading: Fresh face and new cabin in big refresh for Mercedes-Benz GLS

Second update for third-generation SUV includes new rear screens and punchy 3.0-litre straight six

The Mercedes-Benz GLS has been heavily refreshed, gaining a redesigned interior and an enhanced petrol straight six.

This is the second update for the third-generation SUV since it was launched in 2019. It arrives alongside the similarly updated GLE SUV and GLE Coupé.

Still available with either five or seven seats, the GLS has received a heavy interior redesign, which has been modelled heavily on that of the recent S-Class update.

The most notable changes come at the rear of the cabin, where, as in the S-Class, a pair of 11.2in touchscreens have been fitted. These can be used to watch films or engage in video calls. 

There are also now iPhone-like controllers that can operate the seats, control infotainment functions, close the blinds and even change the colour of the ambient lighting.

In the front, the dashboard-wide Superscreen and 18in augmented-reality head-up display are now standard. There's also a new steering wheel that features physical rocker controls. 

In seven-seat models, the second bench can be electronically moved forward to increase leg room in the third row. 

Externally, like the GLE, the front gains a new front bumper, grille and headlights. In AMG Line trim, the grille is illuminated.

At the rear, the Mercedes logo is now incorporated within a new light bar.

New 23in wheels are exclusive to the GLS. 

The line-up starts with the 308bhp straight-six diesel 350d and tops out with the 530bhp 4.0-litre V8 turbo petrol 580, which enables the GLS to cover 0-62mph in 4.7sec.

Back to top

Mercedes’ updated ‘M256 Evo’ 3.0-litre turbo petrol straight six is offered on 450-badged variants and makes 375bhp – 74bhp more than before, thanks to a new cylinder head, larger intakes and new exhaust ports.

All powertrains use an automatic gearbox and four-wheel drive. 

Unlike the GLE, the GLS isn't offered with a plug-in hybrid powertrain. It also doesn’t get an AMG-badged 53 variant, but an updated version of the supercar-baiting AMG GLS 63 is expected later this year.

The previous model drew power from a 4.0-litre twin-turbo petrol V8 that put out 603bhp and 627lb ft of torque.

Pricing for the updated GLS has yet to be announced but will increase over today’s £110,800. It will go on sale later this year.

Bit old fashioned?, not a fan of the trend in triangular brake lights,maybe it just the color of the example we see here?
