Mercedes claims that up to 95% of the energy from the EQXX’s battery ends up at the wheels. By comparison, ICE vehicles typically operate at around 30% efficiency.
Rated at 201bhp, the EQXX’s compact new motor is mounted within a lightweight carbonfibre subframe at the rear and drives through a single-speed transmission.
It’s controlled by a power electronics system based heavily on that of the Mercedes-AMG One hybrid hypercar, albeit with a new generation of silicon carbides for what Mercedes said is a significant reduction in losses compared with the systems in place on EQ-badged models today.
“Electric range sounds easy but is a complex technical challenge,” said Joerg Bartels, head of the EQXX engineering team. “The easiest way is to put a bigger battery in the car. However, this leads to diminishing returns, due to size and weight. With the Vision EQXX, we’ve managed to push efficiency to a new level.”
The front of the EQXX takes on a sports car-like appearance, with a low leading edge, a short bonnet, shapely fenders and large wheelhouses. The signature Mercedes grille is replaced by a star graphic incorporated within the front bumper, while the digital LED headlights are conjoined by a full-width LED light bar.
