The U.S. Environmental Protection Agency (EPA) has released its official reports on the Tesla Cybertruck, revealing additional details about the electric truck. Information in the documents, reviewed by InsideEVs, indicates some noteworthy details.

Firstly, the Certification Summary Information Report, filed on November 21, 2023, reveals a total battery pack voltage of 816 volts, a battery energy capacity of 150 amp-hours, and a battery-specific energy of 170 watt-hours per kilogram. This results in a total energy capacity of 122.4 kilowatt-hours, consistent with unofficial reports of 123 kWh. It's worth noting that Tesla does not officially disclose the battery capacity of its electric vehicles.

The document also confirms the presence of Tesla's Heat Pump system. This is not surprising, as most new Tesla vehicles are equipped with this system. Some spy shots shared earlier this year by members of the Cybertruck Owners Club had already exposed the cooling systems behind the front trunk.

For those unfamiliar, Tesla's Heat Pump system is a solution designed to minimize heat losses, maximize range, and enhance efficiency within the vehicle. Essentially, heat pumps reuse the heat generated by the battery and drive units to warm the cabin, saving energy and improving range on long drives—especially crucial in winter when range losses tend to be higher. The document describes the location of the heater unit and how it incorporates a variable-speed electric fan, directing blown air to various vents in the passenger compartment.

Regarding charging, a quirky detail was discovered. The charging port, located on the rear left fender, will display a colorful indication of its state of charge. For example, solid white illumination indicates that the charging cable can be removed or inserted, while an orange light signals that the cable isn't properly latched. A flashing blue light indicates that charging is underway as expected.

Lastly, the curb weight of the Cyberbeast is 6,898 pounds, and the all-wheel-drive variant weighs 6,669 pounds. The gross vehicle weight rating (GVWR) is 9,169 pounds for both variants. Unfortunately, details about the rear-wheel-drive Cybertruck, expected in 2025, are not yet publicly available from the EPA.

In conclusion, while these EPA documents provide valuable insights into the Tesla Cybertruck's technical details, there is still anticipation for more information and test results, especially regarding the vehicle's internal systems, power system, and battery design, which have not been officially disclosed in precise detail yet.
