How the Volkswagen ID.7 Hits the 700 KM Range with Top-Notch Aerodynamics

  • The Volkswagen ID.7 achieves 700 KM range due to superior aerodynamics and low drag coefficient.

  • Extensive development work fine-tuned body shape, underbody, wheels, and functional openings for optimal airflow.

  • Meticulous design process and testing resulted in a Cd value of 0.23, a Volkswagen ID. family record.


Pushing the boundaries of electric vehicle efficiency, the Volkswagen ID.7 now sets a new standard with a remarkable 700 kilometres (WLTP) range. Achieving this impressive milestone is largely attributed to a combination of outstanding aerodynamics and a low drag coefficient, made possible by tight collaboration between the Design and Development departments.

The ID.7 presents a low front end, a seamless transition into the bonnet, and a swift windscreen, with a coup√©-like roof form and tapering rear end. The vehicle’s silhouette is testament to its status as the most aerodynamic ID. model from Volkswagen.

In the ID.7, the body shape contributes approximately 50% of the Cd value, with wheels, tyres, underfloor, and functional openings also playing a role. From the early development stage, extensive work was undertaken to fine-tune these components. The iterative process involved regular consultations between the departments and computer simulations for flow calculation, supplemented by wind tunnel tests.

The all-new Volkswagen ID.7 possesses an almost entirely closed underbody, supplemented by new wheel spoilers and features such as the air curtains and flared side sills to optimize air flow. In addition, a focus was put on wheel design due to their significant contribution to good aerodynamics in electric vehicles.

Functional openings at the front allow airflows to the radiators, with the airflow actively controlled by a radiator roller blind to reduce drag. The rear of the vehicle was equally considered, with the ideally shaped tailgate and diffuser design enhancing aerodynamic efficiency.

The design team undertook meticulous virtual work during the first year of development, calculating airflow values for numerous minute details. Wind tunnel testing was employed only when the design was considered stable. The result of these efforts was a Cd value of 0.23, the best drag coefficient in the Volkswagen ID. family, cementing the ID.7 as an efficient and range-optimized electric vehicle.
