Meet the Peaq: a large SUV with outstanding aerodynamics

Every thousandth of the drag coefficient matters. Štěpán Janda, Aerodynamics Department Coordinator, explains why: “Every thousandth by which we reduce the drag coefficient translates into approximately one additional kilometre of range – and even more on motorways. And all that comes without adding a single extra battery cell.” 
 
To enable the Peaq to cut through the air as efficiently as possible, engineers fine-tuned dozens of areas and hundreds of details that must work together as a single system. Aerodynamic efficiency is never the result of one solution alone, but rather the sum of many small optimisations. These not only increase the EV’s driving range but also contribute to quiet and comfortable driving and efficient vehicle cooling.

One of the most aerodynamically challenging areas of any vehicle is the wheels. Turbulence generated by rotating wheels disrupts airflow around the vehicle and significantly increases drag. This is precisely why engineers focused extensively on this area during the development of the Peaq. However, no single solution is sufficient on its own, and a comprehensive package of measures is required. 
 
The Peaq uses Air Curtain ducts, familiar from other Škoda models, which channel air through the interior of the front bumper and guide it along the front wheels, helping to reduce unwanted turbulence in this area. Interestingly, their inlets are not positioned directly in the bumper corners, as is usually the case, but closer to the grille. The reason was the Modern Solid design language requirement for a fuller and cleaner front-end corner treatment. “The result is a longer and more complex internal duct, but following extensive aerodynamic optimisation, it performs just as effectively as a traditional solution,” says Václav Ptáček, lead specialist for external aerodynamics on the Peaq project.

The Air Curtain ducts work together with several additional aerodynamic measures around the front wheels, including the integrated wheel-arch spoiler, the underbody air deflector, the active roller blind between the coolers and aerodynamic wheel covers. Their combined effect helps guide airflow around the wheel as cleanly as possible and reduces aerodynamic drag. 
 
The Modern Solid design language itself also contributes to smoother airflow. Its characteristic features include smooth body side, minimal transitions between the side windows and pillars, and flush, retractable door handles. All these details help maintain the cleanest possible airflow along the car’s body.

Aerodynamics influence not only energy consumption and driving range but also other vehicle characteristics. “The exterior mirror clearly demonstrates that aerodynamics are not only about dragreduction. Its shape also affects wind noise and how quickly the mirror glass becomes dirty during driving,” points out Štěpán Janda, highlighting one of the many important details.  

Engineers fight the final aerodynamic “battle” at the rear of the vehicle. The way air leaves the vehicle has a crucial impact on the final drag figure. “Together with other rear-end elements, the roof spoiler precisely controls the vehicle’s wake, meaning the airflow behind the car,” says Václav Ptáček. The spoiler’s distinctive three-dimensional shape was developed through close collaboration between aerodynamicists and the Design team, combining low aerodynamic drag with a modern look. The side finlets, the sharp trailing edges around the tail lamps and bumper, and the rear diffuser with its aero spoiler all play an important role.
