Volkswagen's Mission Efficiency concept vehicle achieved a documented range of 1,278 km (794 miles) on a single charge with 164 km (102 miles) remaining, suggesting a theoretical total range exceeding 1,400 km (870 miles). Built on the MEB+ platform shared with the ID. Polo, the front-wheel-drive 2+2 coupe uses a 54.9-kWh net battery and standard powertrain components rather than exotic technology.

Instead, Volkswagen focused on extreme aerodynamics, achieving a drag coefficient of 0.158 — claimed as the lowest for any road-legal car — and a frontal area of just 2.08 square meters. During a certified record run from Wolfsburg to Vienna via Poznań and Olomouc at an average 67.72 km/h, the vehicle consumed 6.89 kWh/100 km without charging losses. Germany's Record Institute (RID) certified it in the "near-production, everyday-use four-seat electric vehicle" category.

Despite its teardrop-shaped, boat-tailed profile inspired by the XL1, the concept offers 481 liters of cargo space, fold-flat rear seats, and practical storage. The low-slung coupe measures 4,775 mm long and 1,392 mm tall with a 2,700-mm wheelbase.
