Mercedes’ super-efficient EV concept has a stated range of over 1,000 kilometres and is powered by a 100kwh battery.
The Mercedes-Benz Vision EQXX concept is said to set new energy efficiency norms with a “real-world range of more than 1,000 kilometres,” which is 230 kilometres longer than the EQS flagship EV.
- The Vision EQXX Concept is sized similarly to a C-Class
- It uses a single rear-mounted 204hp electric motor
- Interior has a 47.5-inch digital display; cabin uses sustainable materials
What is the Mercedes-Benz Vision EQXX concept?
The rakish compact car is the latest in a long series of Mercedes-Benz design studies that have been made public. It was created to put existing EV concepts to the test in a programme aimed at hatching new ideas, techniques, and technologies for use in future EVs.
The concept is a running and driving prototype, according to Mercedes chief technology officer Markus Schäfer, and it even incorporates a version of the existing MBUX infotainment system. It uses a prototype of Mercedes-next-generation Benz’s EV drivetrain, which will go into production in 2024 and has new battery technology.
The EQXX is “at least one segment smaller” than the EQE, according to chief designer Gordon Wagener, implying that it might be produced as an electric counterpart of the C-Class in the future.
The EQXX is claimed to set a new record for aerodynamic efficiency, with a drag rating of less than 0.18Cd, whilst complying with all existing German roadworthiness rules and seating for four adults. This contrasts with the EQS’s 0.20Cd.
Exterior design of Mercedes-Benz Vision EQXX concept
With a low leading edge, a short bonnet, shapely fenders, and wide wheelhouses, the EQXX has a more sports car-like appearance up front. The Mercedes grille has been replaced with a star logo integrated into the front bumper, and the digital LED headlights have been joined by a full-width LED light bar.
Mercedes’ star insignia is stencilled onto the bonnet to conserve weight and achieve optimal aerodynamic performance. Using a series of air curtains and air breathers, a ‘air management system’ guides air through the front part of the new concept car.
Mercedes has also added ‘ninth-generation’ exterior mirrors and freshly built, aero-optimized wheels to the EQXX.
Because there are no drivetrain components in the nose section, the EQXX’s A-pillars are situated well forward, and its wheelbase stretches to 2,800mm, maximising cabin space.
The active aerodynamic innovations previously investigated by Mercedes on the Concept IAA in 2015 are carried over to the EQXX at the rear. A diffuser element is included, which extends automatically as airflow increases, smoothing airflow and reducing turbulence.
The EQXX is also somewhat tapered, with a 50mm narrower rear track than the front.
Interiors of the Mercedes-Benz Vision EQXX concept
The huge 47.5-inch continuous display that covers the width of the dashboard catches the eye on the inside. The display itself has an 8K resolution and serves as the instrument cluster (the area in front of the driver) as well as the infotainment system.
Mercedes has also gone to great lengths to use environmentally friendly materials throughout the cabin. These materials include a fabric produced from bio-steel silk-like fibre, vegan leather made from mushrooms or cactus fibres, and bamboo-fiber carpets.
The powertrain and batteries in the Mercedes-Benz Vision EQXX concept
Mercedes-AMG High Performance Powertrains, situated in the United Kingdom, is claimed to have made significant contributions to the EQXX development programme. Mercedes-AMG High Performance Powertrains manufactures the sophisticated V6 turbo-hybrid powertrains for Mercedes’ Formula 1 cars.
The high efficiency rating of the rear-wheel-drive sedan, which is nearly double that of the Mercedes-Benz EQS on the WLTP test procedure at more than 9.97km per kWh, is central to the remarkable range achieved by the rear-wheel-drive sedan.
It was accomplished with the help of a newly built motor and a custom lithium-ion battery, which, at just under 100kWh, has a smaller overall energy capacity than the EQS, which has a range of 770 kilometres.
The 1750kg EQXX’s new battery, which uses cells supplied by Chinese battery expert CATL, is also touted to be “50 percent the size” of the EQS’s 107.8kWh pack and is roughly 35 percent lighter, weighing around 495kg. The new high-silicon-content battery, according to Mercedes, functions at more than 900V.
Mercedes claims that up to 95% of the energy stored in the EQXX’s battery is transferred to the wheels. ICE vehicles, on the other hand, are typically approximately 30% efficient.
On the roof of the Vision EQXX concept car are 117 solar cells that power the car’s ancillary systems. Over the course of a day, the solar panel alone can contribute 25 kilometres of range in good weather circumstances.
The EQXX’s compact new motor, rated at 204 horsepower, is housed in a lightweight carbonfibre subframe at the back and drives through a single-speed transmission.
