2024 Tesla Cybertruck

The Tesla Cybertruck’s funky design may look like an aerodynamic nightmare, but Tesla’s engineers have gone above and beyond by ensuring the electric pickup has a drag coefficient of 0.34. While that’s not as good as Tesla’s other EVs, it’s better than the Jeep Wrangler, which has a drag coefficient of 0.48. Surprisingly, there’s one easy way to help the Cybertruck slip through the air – close the tonneau cover.

Car and Driver got its hands on a Cybertruck Cyberbeast model that has three electric motors with up to 845 horsepower and a range of up to 320 miles. The organization tested the electric truck at 75 mph with the tonneau open, closed, and with both the tonneau and tailgate open to see if the Cybertruck’s range was affected by the changes.

With the Cybertruck’s tonneau cover closed, the pickup truck consumed 58.3 kilowatt-hours per 100 miles compared to 64.2 kWh per 100 miles with the cover open. The organization found that simply closing the tonneau cover can increase the Cybertruck’s range by 10%. In Car and Driver’s 250-mile range test with the pickup truck, having the tonneau cover open would have resulted in a range of 225 miles. These figures are for the truck traveling at 75 mph.

When traveling at 65 mph, the outlet found that energy consumption was a lot better with the Cybertruck. With the tonneau cover opened, the Cybertruck consumed 58.3 kWh per 100 miles. Closing the cover resulted in a consumption of 49.3 kWh per hour.

Drivers who keep the Cybertruck at 65 mph on the highway and keep the tonneau cover closed can get up to 295 miles of range from the truck. For the record, that’s below Tesla’s rating of 320 miles and the automaker’s initial estimate of 500 miles when the truck was first introduced. But it’s still impressive for a truck of its size and performance.
