Mercedes-Benz has been testing its next GLS moved to the Nürburgring, where the heavyweight SUV is thoroughly checked before its expected public debut later this year.
Although heavily camouflaged, the successor to Mercedes’ current flagship model of the SUV can be seen sporting a design similar to that of the smaller and recently discovered new GLE, which is also due out later this year.
The GLS is clearly stressed as a larger scale due to its boxier rear section, although part of this is applied to the cladding to hide the development of the car, its design.
Like the current GLS, the next-gen car many parts with the S-class luxury sedan, including its drives. The S-class gets six-and eight-cylinder Turbo-diesel, six-cylinder turbo-diesel and a petrol-electric plug-in hybrid, so expect a similar line-up with the GLS.
The latter electrified powertrain will be the key to ensure that the GLS can compete in regions with strict emission limits as well as providing Mercedes with a significant CO2-cutting for the model to help survive in the next generation of CO2-limit value of the execution, which comes to power after 2020.
Key to this will be, 48V electric system, to activate an auxiliary electric heater, the compressor and the integrated starter generator mild-hybrid running in non-plug-in models.
At the top of the range GLS-63 with AMG twin-Turbo 4.0 Liter V8 engine to offer probably with the same 612bhp than the S63.
A lot of the SUV’s in-car tech will also be performed compared to the S-class, including its highly developed Autonomous functions. 2017 S-class led Mercedes’ latest Distronic Active cruise control and Active Steer-Assist systems, the speed and automatically brakes the car within the posted speed limits provides Autonomous steering for a period of up to 30sec.
