Mercedes-Benz could bring an electric vehicle with about 1,000 km (more than 620 miles) of range to the market by mid-decade.
The automaker said it has developed a beefy battery that can power a vehicle from Stuttgart to Paris and back on a single charge.
The battery, featured in the Vision EQXX concept, will make its way into a production vehicle around 2024, Mercedes-Benz Chief Technology Officer Markus Schäfer said.
The Vision EQXX is "more than a halo car, it's more than a concept car — it's a technology program," Schäfer told journalists on a conference call. "We gave a simple task to the engineering organization: Create the most efficient electric vehicle that Mercedes has ever built."
To get there, Mercedes engineers worked with the automaker's Formula One and Formula E motorsport divisions to eke out efficiency improvements in the electric motor, inverter, battery design, packaging and thermal management.
The Vision EQXX, which stretches the imagination with a mix of fantastical technologies and lightweight materials, is a template for future Mercedes models.
Daimler plans to invest more than $46 billion from 2022 to 2030 to develop EVs and become an all-electric brand in markets ready for the switch.
