Volkswagen’s crazy-efficient EV borrows an idea from Slate

The efficiency benchmark set by Volkswagen could pressure automakers to prioritize aerodynamic design and reduce vehicle weight.

Volkswagen successfully drove its Mission Efficiency prototype EV on a 794-mile journey from Wolfsburg, Germany, to Vienna, charging only once and arriving with 104 miles of range remaining. This demonstrated an efficiency of 7.51 kilowatt-hours per 100 miles, or approximately 279 MPGe, which is nearly double the efficiency of the Lucid Air Pure. The prototype utilizes the electric motor and battery from the ID. Polo, achieving near-production status. To maximize aerodynamic efficiency, the vehicle features a Kammback design with a low coefficient of drag (0.158) and a small frontal area (2.08 sq meters), resulting in a 2+2 seating configuration with limited rear passenger space. Further efficiency measures include minimized wheel arch gaps and the integration of solar cells on the roof and trunk lid, though their energy contribution is modest. Echoing EV startup Slate Auto, the Mission Efficiency omits an infotainment system and speakers, expecting drivers to use personal devices and portable Bluetooth speakers.

Volkswagen's Mission Efficiency prototype showcases an extreme focus on aerodynamic design and lightweight construction, achieving efficiency levels significantly beyond current production vehicles. This suggests a potential future direction for EVs where range is achieved through radical design rather than solely larger battery packs. The integration of a Kammback shape, minimal frontal area, and even the deletion of traditional infotainment systems indicate a willingness to make significant compromises for efficiency, a strategy that could trickle down to more mainstream models if consumer acceptance allows.

The adoption of an infotainment-free cabin, inspired by startups like Slate Auto, signals a growing trend of automakers looking to externalize components and leverage user-owned devices. This approach can reduce manufacturing costs and complexity, while also potentially offering users a more personalized and up-to-date interface through their smartphones. However, it also raises questions about user experience, accessibility, and the perceived value proposition of a vehicle that relies heavily on personal technology.
