New Mercedes-Benz GLS: UK pricing and spec revealed

The new Mercedes-Benz GLS luxury SUV is now available to order in the UK, costing from £73,995. 

Revealed at the New York motor show, the GLS has been completely re-engineered in an attempt to improve on the refinement and efficiency of rivals such as the new BMW X7 and Range Rover.

In the UK, the car will initially only be offered in GLS 400d trim, featuring the range-topping 2.9-litre inline six-cylinder diesel engine, with 325bhp and 516lb ft of torque. Official (WLTP) fuel economy and CO2 emissions are 37.2mpg and 201g/km. 

Three trim levels will be available. Entry-level AMG Line Premium models comes with the latest version of Mercedes’ MBUX infotainment system, 22in wheels, heated front and rear seats, a Burmester surround sound system, 360deg parking camera, head-up display and a panoramic roof.

Additions for the AMG Line Premium Plus trim include augmented-reality navigation, multi-contoured massaging seats, an MBUX rear-seat entertainment system, temperature-controlled cupholders and heated armrests. The top AMG Line Premium Plus Executive trim includes 23in wheels, a nappa leather steering wheels, massaging rear seats, electric sunblinds for the rear doors and heated seats for the third row.

All three trim levels are available with a £1495 Off Road package, which includes variable all-wheel drive and low-range transmission, inter-axle locking, low-range off-road gearing, off-road ABS and special off-road drive modes.

Following the standard seven-seater, an uber-luxurious Maybach version will arrive, aimed directly at the Bentley Bentayga.

The new GLS is will be produced with four engines – two petrols and two diesels – from the outset.

Outside of the UK, a lower-tuned version of this engine will be offered in the GLS 350d, making 282bhp and 442lb ft.

Both of these models use a 31.6-litre AdBlue tank and a secondary ammonia filter, enabling them to comply with 6d-Temp regulations on the Real Driving Emissions Stage 2 test, which will become mandatory from 1 January 2020.

The petrol line-up is headed by a new 48V mild-hybrid engine in the range-topping GLS 580. This combines Mercedes-Benz’s twin-turbocharged 4.0-litre V8 with an electric integrated starter motor, delivering 482bhp and 516lb ft of torque, with a further 22bhp and 147lb ft for available for a brief period under acceleration.

The GLS 450 is also a 48V mild hybrid, using a turbocharged 3.0-litre inline six-cylinder engine and an integrated starter motor for 362bhp and 369lb ft, with an additional 22bhp and 184lb ft available under acceleration.

According to Mercedes, the 400d’s engine is “perfectly suited to the vehicle’s size and weight, and the performance expectations of our customers”.

All engines are combined with a nine-speed torque converter automatic gearbox and the latest version of Mercedes’ 4Matic four-wheel-drive system, which provides fully variable apportioning of power between the front and rear axles.  

Two AMG performance versions of the new GLS will arrive in 2020, with the GLS 53 using a mild-hybrid petrol engine and the GLS 63 a twin-turbocharged 4.0-litre petrol V8.

Mercedes is also preparing to offer the SUV with an updated version of the petrol-electric plug-in hybrid powertrain used by the S560e with a significantly greater electric-only driving range.
