Cybertruck Efficiency: Impact of Tonneau Cover on Range Revealed

Published Categorized as Cars No Comments on Cybertruck Efficiency: Impact of Tonneau Cover on Range Revealed

The efficiency implications of driving with open windows or an uncovered bed have intrigued many, especially in the context of Cybertruck’s unique design. While findings have been inconclusive, there’s tangible evidence that closing the tonneau cover can significantly enhance the Cybertruck’s range.

Numerous tests, including one conducted by the MythBusters television show, have failed to provide definitive conclusions on how aerodynamics are affected by open windows.

However, the Cybertruck’s distinct design, resembling a brick-shaped truck, suggests minimal aerodynamic impact from windows being open or closed, similar to most combustion vehicles where aerodynamics play a minor role.

In contrast, electric vehicles like the Cybertruck prioritize aerodynamics due to their limited battery capacity, necessitating optimal efficiency to maximize range. A slight decrease in efficiency, even by five percent, could result in insufficient charge for longer journeys, underscoring the importance of aerodynamic optimization.

Car and Driver’s testing of the Cyberbeast variant, equipped with 35-inch all-terrain tires, on a 6.6-mile oval track at 75 mph, revealed significant differences in energy consumption with the tonneau cover closed versus open.

With the cover closed, energy consumption averaged 58.3 kWh per 100 miles, compared to 64.2 kWh per 100 miles with it open, representing a notable 10% increase in consumption.

These findings suggest that driving with the tonneau cover closed is beneficial for extending the Cybertruck’s range, particularly at higher speeds. Lowering the speed to 65 mph further improves efficiency, highlighting the significance of aerodynamic optimizations for electric vehicles like the Cybertruck.
