Volkswagen’s slippery new EV breaks a bunch of efficiency records

Volkswagen has revealed the Mission Efficiency, a near-production electric coupe built on its MEB+ architecture that the company says sets new benchmarks for aerodynamic and energy performance. The prototype is a 2+2 configuration and uses front-wheel-drive components shared with upcoming ID. Polo and ID. Cross models.

VW reports a drag coefficient of 0.158, which it calls the lowest for any road-approved vehicle, and cites a controlled test consumption of 6.48 kWh per 100 km at a steady 68 km/h with auxiliary systems turned off. In a real-world demonstration the car reportedly covered 1,278.36 km from Wolfsburg to Vienna on a single 54.9 kWh (net) charge, averaging 6.89 kWh/100 km (7.51 kWh/100 km when including charging losses) at about 67.72 km/h and arriving with an estimated 164 km of range left.

The Mission Efficiency achieves these numbers through extreme aero and weight-saving measures rather than novel propulsion hardware. Its body follows a teardrop profile with covered underbody, wheel coverings, frameless windows and flush door handles; paneling and structure use lighter materials and the vehicle shares a 99 kW front motor and high-voltage battery with the ID. Polo. VW says that above 80 km/h the prototype uses more than 30% less energy than an ID. Polo, and at 140 km/h it consumes about as much energy as an ID. Polo does at 100 km/h.

Interior and auxiliary systems were pared back to save mass and drag: the central touchscreen is replaced by a bring-your-own-device setup that uses a portable Bluetooth speaker and a smartphone or tablet dock, while integrated roof solar panels can add up to 30 km of range for auxiliary electronics. VW presents the Mission Efficiency as an example of how design and packaging choices can deliver large efficiency gains, a direction many other manufacturers are also exploring as they chase improved EV range and economy.
