Wind tunnel tests verify Tesla’s Cybertruck drag coefficient measurements

Wind Tunnel Tests Tesla‘s Cybertruck Drag Coefficient Claims

Tesla aimed to achieve excellent aerodynamics with the unique design of the Cybertruck. Back in early 2019, Elon Musk suggested that the electric truck could potentially achieve a drag coefficient (Cd) as low as 0.30. Fast forward four years, the final production-ready Cybertruck hit the streets with an official Cd of 0.34. While this number is respectable within the pickup sector, it falls slightly short of the Cd numbers released by Chevrolet and Rivian.

To validate Tesla’s claims, the i1Tesla YouTube channel took the Cybertruck to A2 Wind Tunnel in Mooresville, NC for testing. After thorough analysis, the Cybertruck was found to have a drag coefficient of 0.384, slightly higher than the official Cd of 0.34. The testing team noted that slight variations in results are expected due to differences in wind tunnel setups.

The team also simulated various driving scenarios, revealing that the truck performed best at a low driving height with the Tonneau cover closed and mirrors removed, averaging at 0.382 Cd. In contrast, the worst results were observed in the Extract high driving mode, with an estimated 0.535 Cd.

Comparing these results with other EV truck manufacturers, the Cybertruck still holds a favorable position between the Silverado EV and F-150 Lightning in terms of aerodynamics. Despite minor discrepancies in the Cd numbers, the Cybertruck showcases its aerodynamic efficiency in the pickup truck segment.
