This is now the new symbolic threshold that manufacturers are trying to reach at all costs, as they try to convince the public at large to switch to all-electric vehicles.

For Mercedes, the Vision EQXX is the most efficient electric prototype ever built, with an energy consumption of less than 10 kWh per 100 kilometres.

This gives it a theoretical range of more than 1,000 kilometres per charge. Compared to what’s currently available on the market, few electric vehicles can drive more than 400 kilometres on a single charge.

It will be many years before a production car offers a range of 1,000 kilometres. But the solution may lie in hydrogen.

Recently, Toyota managed to cover 1,003 kilometres with its Mirai on one tank of hydrogen fuel, a new world record in this field.

In a few years, this level of performance could very well become the norm for this kind of vehicle, at least for certain premium models.
