2021 Mercedes S-Class drops disguise ahead of launch
Hybrid-only S-Class is due to be unveiled this year with evolved styling and a tech-heavy new interior
Mercedes-Benz is due to unveil its new S-Class flagship later this year, and the luxury saloon has been caught with minimal disguise by our photographers.
Previously spotted prototypes wore heavy camouflage, but we can now see clearly that the seventh-generation BMW 7 Series rival takes an evolutionary approach to the exterior redesign, with a similarly curvy look to today's car. The tail-lights take inspiration from that of the latest CLS.
The interior, caught on camera earlier this year, takes a more radical step forward, with a greater emphasis on technology. The minimalist dashboard is dominated by a Tesla-style portrait display - significantly larger than any screen Mercedes has offered in previous models - paired with a freestanding digital instrument display. This week, Mercedes offically unwrapped the interior of the new S-Class, revealing that it will feature the second-generation version of the firm's MBUX infotainment system - with fewer physical controls, five touchscreens and an array of motion-detector, sensor-operated functions.
The seventh-generation S-Class looks set to regain its place at the forefront of the brand's technical know-how, with a range of new electrified powertrains and advanced driver assist features. Comfort and technology levels will take a boost, with the target of lifting it beyond rivals such as the 7 Series and Audi A8.
The new Mercedes flagship, which is due in UK showrooms next year, has been developed to support two distinctly different saloon models for the first time. While standard versions are set to receive a range of plug-in hybrid drivetrains, the German car maker will also launch an aerodynamically optimised pure-electric version that will serve as the flagship model for its new EQ electric vehicle sub-brand.
Badged EQS, the new model will offer a claimed range in excess of 310 miles on the latest WLTP test cycle when it goes on sale in 2022. Plug-in hybrid versions of the S-Class will feature part-time zero-emission capability for distances of up to 62 miles, together with the option of a newly developed 4Matic four-wheel drive system with fully variable apportioning of drive between the front and rear axles.
The EQS forms part of Mercedes’ £9 billion programme to introduce more than 10 dedicated electric vehicles to the UK market within the next six years.
In a further change, it is believed that Mercedes-Benz has decided to do away with its long tradition of offering the standard S-Class, which goes under the internal codename W223, with two different wheelbases. Nothing is official at this stage, but it is understood that the growth of the E-Class to a length of 4920mm is behind a decision to produce the new S-Class exclusively in long-wheelbase guise, with the car measuring around 5280mm in length.
However, while the standard S-Class sits on the MRA platform, the more technically advanced four-wheel-drive EQS will be the first Mercedes-Benz model to be based on the new Modular Electric Architecture (MEA) platform. Unlike the structures being developed to underpin smaller EQ models, it is not based on an existing platform but has been developed as dedicated EV architecture with a flat floor to house batteries.
The drivelines set to power hybrid versions of the new S-Class are based around Mercedes’ latest 3.0-litre and 2.9-litre in-line six-cylinder petrol and diesel engines and the AMG-developed 4.0-litre V8, all of which operate in combination with a disc-shaped electric motor housed within the automatic gearbox and a lithium ion battery located in the boot floor.
The electric EQS is set to receive two electric motors – one acting on the front axle and the other driving the rear – providing permanent four-wheel drive in all variants. In the EQC, this set-up delivers more than 400bhp and some 516lb ft, although engineers involved on the development of the EQS suggest it will offer even greater levels of power and torque, with a planned AMG performance model earmarked to produce more than 600bhp.
Despite the differing platforms, both the standard S-Class and the EQS are set to share the same active suspension system. A development of the existing S-Class’s AirMatic+ system, it works in combination with a 48V electrical architecture and a stereo camera that scans the road ahead to adjust the spring and damper action on each wheel, allowing it to not only counteract body lean in corners but also to better control pitch.
Stylistically, the new S-Class is claimed to break new ground with a lineage that Mercedes-Benz design studio sources say will influence a whole new generation of models. Recent prototype spy shots preview a design that will feature distinctive tri-band LED multibeam headlights, a new interpretation of the classic Mercedes-Benz grille and door handles that retract back into the bodywork to help improve aerodynamic properties.
The EQS will adopt its own distinct styling. Reflecting the packaging advantages inherent in electric vehicles, it receives a shorter bonnet and more heavily raked windscreen than the standard version of the new S-Class, similar to that of the CLS.
