Mercedes-Benz has just unveiled the Vision EQXX and it is heralded by the Stuttgart brand as the pinnacle of automotive efficiency. Just how efficient you may ask? Well with a drag coefficient of just 0,17 it is rather efficient, allowing for over 1 000 km on a single charge.
What that would mean is that granted one stops for a Wimpy toasted sandwich in Bloemfontein and tops the battery up, Johannesburg to Cape Town is completely doable without the stress of range anxiety ruining the family holiday. At the unveiling, Mercedes-Benz claimed that the average American driver would only need to recharge the EQXX twice a month.
Mercedes-Benz is keeping mum at the moment regarding the EQXX’s battery capacity, however they have said that it has less than 100 kilowatt-hours and the unit displaces 50% less than that of the EQS, while also being 30% lighter than that battery. The system’s maximum voltage is 900 volts and together, the battery and the frame that carries it weigh just under 500 kg. The electric motor has 120 kW and Mercedes-Benz are so confident in its efficiency that they say 95% of that energy ends up at the wheels. Additionally, a 117-cell roof-mounted solar panel powers ancillary electric systems such as the air-conditioning blower, infotainment system and vehicle’s lights which all feed off a lithium-iron-phosphate battery which stores the energy from the solar panel. Depending on the conditions, this tech is able to free up to 25 kilometres of range.
In terms of its dimensions, the EQXX is roughly the same size as a new C-Class and weighs around 75kg more than a C300, tipping the scales at just 1 750 kg. That’s fairly light as far as EV’s go, a lot of that weight saving likely down to that snazzy new battery.
The EQXX’s incredibly low drag coefficient comes as a result of the vehicle’s teardrop shape and minimal shut lines, the removal of which all reduces parasitic drag. Myriad technologies help the EQXX slip through the air such as air curtains incorporated into the front bumper, as well as wheel covers which eliminate aerodynamic separation at the front corners. Active cooling shutters in the front grille open as and when required, as well as a diffuser at the rear which deploys at high speeds and sits neatly tucked away at lower speeds. Bridgestone has also developed ultra-low-rolling-resistance tyres which feature specially optimised sidewalls that fit together with the wheel covers.
The cabin feature an 8k, 47,5 inch seamless display from A-pillar to A-pillar with an advanced 3D navigation system able to show a satellite view right down to a height of just 10 metres. Sustainable materials have been used throughout the interior, including a fabric that uses a Biosteel silk-like fibre, mushroom-based vegan leather, animal-free leather from pulverized cactus fibre, and bamboo-based carpets.
There’s no word yet on which elements of the vehicle or indeed whether or not the whole Vision EQXX will be put into production, nor have we been given any timelines by the German automaker.
