The Aerodynamic Secret of the A2 e-tron

The Aerodynamic Secret of the A2 e-tron examines how Audi reimagined an iconic silhouette to set a new benchmark in electric vehicle efficiency. Measuring 4.32 meters in length, the A2 e-tron achieves a class-leading drag coefficient of 0.24 by seamlessly blending signature heritage features—such as the arched roofline and blunt rear (coda tronca / Kamm-back profile)—with cutting-edge surface engineering to optimize laminar flow1more_horiz.

This relentless focus on drag reduction and wake turbulence minimization serves as the primary engineering driver behind the vehicle's impressive 646 km WLTP range more_horiz, giving it a clear efficiency advantage over compact rivals like the Volvo EX30.
