The A2 e-tron is being touted as the most efficient Audi of all time, with preliminary energy consumption based on WLTP measurements being 12.8 kWh per 100 km. This is for the variant fitted with the optional efficiency package and an electric motor with a nominal output of 190 PS (188 hp or 140 kW). Audi also states the A2 e-tron will come with a vehicle-to-home (V2H) system that delivers up to 11 kW to a DC wallbox to power homes in case of emergencies. The electric motor drives the rear wheels and has the power electronics positioned above it. The new A2 e-tron will be unveiled in fall 2026, which is sometime between September and November.
