Small Volkswagen battery tops 400 miles

Volkswagen unveiled the Mission Efficiency prototype on Sept. 14, 2026, using an ID. Polo motor and 54.9-kWh battery, a store of energy, for over 400 miles. That is almost twice as efficient as Lucid Air Pure, rated at 420 miles from an 84-kWh pack. It is not an official EPA rating, the U.S. standard.
