Overview
The Cybertruck, developed over four years, incorporates several new technologies. This article summarizes teardown, analysis, and related information.
Powertrain and battery
Tesla's Cybertruck AWD (dual motor) and Cyberbeast (tri-motor) configurations both use a 123 kWh battery pack. The range extender is a 50 kWh battery pack.
The Cybertruck uses V4 Super Charging with charging rates up to 350 kW. The battery is divided into four modules; an internal switch allows switching between 400 V and 800 V to optimize charging on 400 V and 800 V DC fast chargers.
Battery pack design
The physical battery pack resembles the Model Y in design and is essentially a larger version of the Model Y 4680 battery pack.
Steer-by-wire system
Tesla's new steer-by-wire patent replaces the mechanical intermediate shaft used in traditional steering with an electronic system that transmits the driver's steering intent and provides road feedback via electrical signals. The design aims to improve driving efficiency and steering feel. The system has been implemented.
In Tesla's steer-by-wire system, redundant components are partition-isolated so that the failure of one or more components does not compromise system safety.
Range extender
Tesla also uses an auxiliary range-extender battery to increase range. There is an add-on battery system stored in the trailer trunk that can provide an additional 100+ miles of range.
