Mercedes-Benz Vision EQXX revealed – highly efficient experimental prototype with over 1,000 km of range


After what appeared like an eternity (it was truly a yr and a half), Mercedes-Benz has lastly debuted the Vision EQXX, an experimental prototype designed to push the boundaries of electrical car effectivity. The firm has launched all of the headline numbers, and they’re phenomenal to say the least.

The aim was to ship elevated range with out consequently upping the battery measurement by making the automobile extra efficient, feeding into the virtuous cycle of steady weight discount and permitting the EQXX to journey additional with much less battery. And boy, have they achieved it – regardless of having an analogous battery capability because the EQS at lower than 100 okayWh, the EQXX has a staggering range of over 1,000 km in accordance with simulations.

Mercedes achieved this spectacular determine by decreasing the vitality consumption to underneath 10 okayWh per 100 km (or should you choose, greater than six miles or practically 10 km per okayWh). It begins with a slippery teardrop-like form that has a drag coefficient of simply 0.17 (decrease even than the EQS’ 0.2 Cd), which Stuttgart says is extra aerodynamic than an American soccer.

Key to that is the small frontal space (smaller than that of the CLA), which incorporates a slim air consumption and a flat Three-Pointed Star badge and bumper motif to maximise aerodynamic effectivity. Twin vents duct the cooling air over the bonnet slightly than underneath the automobile to scale back interference drag across the wing mirrors, whereas the air curtain inlets on the bumper corners work with the wheel covers to get rid of airflow separation.

The glossy physique and glasshouse taper in the direction of the rear of the automobile, leading to a rear observe that’s 50 mm narrower than the entrance. This culminates within the sharp cutoff on the rear of the automobile, emphasised by the gloss black trim and curved full-width taillights. The massive rear diffuser extends outwards at increased speeds to scale back drag however retract instantly within the occasion of a rear-end collision.

Although the EQXX was designed for effectivity first, there are a number of gildings labored into the physique. The entrance finish incorporates a full-width mild bar typical of Mercedes’ EQ fashions, with the projector headlights additionally that includes the Three-Pointed Star graphic within the daytime operating lights – a function that can make its method to future fashions, alongside with the two-dimensional Tristar bumper sample.

The double-spoke cast magnesium wheels measure 20 inches in diameter and have rose gold detailing on the centres and covers, mirroring the accents on the entrance splitter and rear diffuser. They are wrapped in ultra-low-rolling-resistance Bridgestone Turanza Eco tyres that incorporate the Japanese tyre maker’s Enliten and ologic know-how.

Another space the place Mercedes has squeezed the utmost out of its elements is the electrical powertrain, with a claimed vitality effectivity of 95% from the EQXX’s 150 kW (204 PS) unit. The drive unit, which consists of the motor, transmission and energy electronics, was developed in conjunction with the eight-time Formula 1 championship-winning Mercedes-AMG High Performance Powertrains (HPP) in Brixworth – in reality, the ability electronics unit is predicated on the one off the AMG One hypercar.

“We worked on every part of the system to reduce energy consumption and losses through system design, material selection, lubrication and heat management,” stated electrical drive system chief engineer Eva Greiner. “And our fantastic simulation tools helped us find out quickly what works and what doesn’t.”

The battery was additionally collectively developed with HPP and is half the dimensions and 30% lighter than the one within the EQS, permitting it to be packaged into the smaller EQXX. The excessive vitality density of 400 Wh per litre comes courtesy of an elevated silicon content material within the extra superior anode composition, higher integration and the separation of electrical and digital elements. The battery is rated at 900 volts, incorporates a light-weight lid made out of sugar cane waste strengthened with carbon fibre, and weighs round 495 kg.

Elsewhere, the EQXX options a complicated thermal administration system that preserves thermal vitality and considerably reduces cooling drag. It’s small and light-weight because of the minimal waste warmth generated by the drive unit and takes benefit of the rigorously balanced interplay between the lively grille shutters, coolant valves and water pumps. The cooling plate is situated underneath the ground of the automobile and is cooled by the airflow beneath, enabling the automobile to journey 20 km additional in its most aerodynamic mode.

The warmth pump additionally makes use of each waste electrical warmth and the ambient air to warmth the cabin, a primary for the model that helps increase range in colder climates; it even makes use of warmth from enthalpy on the evaporator, precipitated when water vapour is changed into a liquid. In hotter areas, the photo voltaic panel on the roof expenses a separate lithium-iron-phosphate battery used to energy the air-conditioning blower, lights, infotainment system and different ancillaries, boosting range by as a lot as 25 km in superb circumstances.

Weight is one other enemy of effectivity, so the EQXX has been constructed to be as mild as doable. Engineers took loads of inspiration from Mother Nature, together with for the single-piece BIONEQXX rear ground, presently the most important aluminium structural casting ever produced by Mercedes.

This part makes use of materials solely the place obligatory on load-bearing paths, making a web-like construction that’s protected utilizing 3D-printed patches from UBQ Materials, made out of recycled waste that will in any other case have ended up in landfills. Overall, this observe saves weight by between 15 and 20% over a traditional part and helps the EQXX obtain a kerb weight of round 1,750 kg.

The EQXX additionally marks Mercedes’ first use of MS1500 ultra-high-strength martensitic metal, in addition to flat metal made out of 100% scrap metallic. A combination carbon and glass fibre is used within the doorways, strengthened with aluminium and a polyamide foam. The brake discs, in the meantime, are made out of aluminium and shave a major quantity of weight and brake mud in comparison with metal rotors. Fibreglass springs are additionally fitted.

Inside, the EQXX options the primary single-piece full-width show – an 8K mini-LED panel that spans 47.5 inches from A-pillar to A-pillar. The infotainment system that runs the display incorporates a star-cloud avatar (impressed by Mercedes Jellinek, the supply of the model title) and a 3D navigation display.

The EQXX additionally will get a a extra superior “Hey Mercedes” voice management system. The latter utilises a still-fledgling know-how referred to as neuromorphic computing, operating on “spiking neural networks” impressed by the human mind that makes the system 5 to 10 instances extra efficient in comparison with standard voice management.

The relaxation of the cabin incorporates a futuristic design and takes sustainability to a brand new stage. The fake Mylo leather-based, as an illustration, is made out of the mycelium of mushrooms, whereas Deserttex leather-based produced from pulverised cactus fibres mixed with bio-based polyurethane can also be used. Textiles made out of recycled polyethylene (PET), bamboo fibres and Biosteel fake silk may be discovered elsewhere within the cabin, as can Dinamica microfibre utilized in many Mercedes fashions – this time made out of 38% recycled PET.

As per the brand new S-Class, the EQXX will get a “4D” encompass sound system, however one which has once more been redesigned to scale back vitality consumption. The audio system have been made smaller and positioned nearer to the occupants’ ears to stop distortion and embody headrest-mounted items. Bass exciters proceed to be fitted on every seat to permit passengers to “feel” the music.

Mercedes says the EQXX was developed in double-quick time, utilizing digital improvement instruments and digital testing to shorten the lead time to simply 18 months. While the automobile received’t make it into manufacturing, a lot of the learnings are already being built-in into future autos, together with compact and midsize electrical fashions constructed on the Mercedes-Benz Modular Architecture (MMA).
