Hybrid-only 2023 Mercedes-Benz GLE to cost from £77,890

In terms of driver assistance systems, a more advanced version of the Mercedes-Benz Distronic active cruise control will be added alongisde a new Parking Package with 360deg camera support.

While maximum towing capacity remains at 3500kg, the optional Trailer Assistant has been given increased functionality, enabling it to automatically control the steering angle and be able to provide reverse manoeuvering at up to 90deg. This is done via controls in the 12.3in central touch display.

Also new to the GLE is Mercedes' Smart Home function. It networks the new SUV with a selected address using WLAN and sensors, allowing occupants to check if anyone is at their home via a “Hey Mercedes, is anyone at home?” spoken instruction. It also allows lights, blinds, heaters and other appliances to be operated remotely from the SUV.

Production at Mercedes' factory in Tuscaloosa, Alabama, the facelifted GLE will be produced with a trio of mild-hybrid petrol and diesel engines, as well as petrol-electric and diesel-electric plug-in hybrid drivetrains and an AMG powerplant in the successor to the range-topping GLE 63 S.

In UK markets, the base GLE 300d uses the OM654 turbocharged 2.0-litre four-cylinder diesel engine, with output reduced by 3bhp to 265bhp, with torque remaining the same at 406lb ft. As before, it's supported by a 48V integrated starter-generator (ISG), providing an additional 20bhp and 148lb ft.

The turbocharged 3.0-litre in-line six-cylinder diesel engine (OM656) in the GLE 400d adopts a 48V electrical system and mild-hybrid properties, giving rise to a new GLE 450d model. This develops an additional 36bhp at 362bhp, with torque extending by 37lb ft to 553lb ft. 

As with the four-cylinder diesel engine, ISG provides the reworked six with an added 20bhp and 148lb ft. It will also feature technology wherein the engine will switch off entirely at a coast for reasons of fuel efficiency. 

The GLE 450 retains the same turbocharged 3.0-litre in-line six-cylinder petrol engine (M256) as before, while receiving a 13bhp bump in power to 376bhp and retaining the same 369lb ft of torque.

The GLE 450 also benefits from 48V mild-hybrid properties, with an ISG delivering the engine an additional 20bhp and 148lb ft.

PHEV engines will be available from AMG line Premium trim and above. The GLE 400e PHEV uses Mercedes' latest turbocharged 2.0-litre four-cylinder petrol engine. The unit, codenamed M254, replaces the 11-year-old M272 used by the preceding GLE 350e. Delivering 249bhp and 295lb ft of torque it's supported by an electric motor mounted on the gearbox, allowing for a 134bhp and 148lb ft power boost. This makes for an overall system output put at 375bhp – some 47bhp more than before – and 443lb ft.

The GLE 350de retains the same turbocharged 2.0-litre four-cylinder diesel engine (OM654) as before. It develops 194bhp and 325lb ft of torque, together with 134bhp and 325lb ft from the electric motor, for an overall system output of 329bhp and 553lb ft.

Both PHEVs receive a 31.2-kWh lithium ion battery. This is claimed to provide the GLE 400e with an electric-only range of between 57.2 and 65.3 miles and the GLE 350de between 55.3 and 65.3 miles.
