Volkswagen has unveiled the Mission Efficiency, a near-production electric prototype that has set three world records. The vehicle features a drag coefficient of 0.158 and achieved a consumption rate of 6.48 kWh/100 km during an ideal test trip. On a documented 1,278.36 km drive from Wolfsburg to Vienna, it recorded a real-world consumption of 7.51 kWh/100 km.

The prototype is built on the MEB+ platform with front-wheel drive, utilizing the same 99 kW electric motor and battery technology found in the ID. Polo. It features a 54.9 kWh net battery, which required only one charge during the long-distance test drive. The car is designed with a lightweight structure using aluminum, carbon fiber-reinforced polymer, and aramid composites.

Aerodynamic features include a teardrop shape, active cooling flaps, and fully clad underbody and rear wheels. The vehicle also employs specialized Continental concept tires with a rolling resistance of 4.9 kg/t. An integrated 370 W photovoltaic system in the roof and boot lid can extend the daily range by up to 30 kilometers depending on environmental conditions.

The interior design prioritizes weight reduction by replacing the standard infotainment system with a 'bring your own device' concept and using a mobile Bluetooth speaker. The coupé measures 4,775 mm in length and offers 481 liters of luggage capacity. Despite its advanced engineering and EU road approval, Volkswagen has stated that the Mission Efficiency will not be sold to the public.
