Model X : Because Teslas Model S does not have an ordinary engine, it does not use a conventional transmission, which has a number of different gears, and a few means to choose from.
The Tesla Model 3 and Model S both use an automatic gearbox fluid that greases single-speed gears. All of the Tesla models, however, use the single-speed gearbox, allowing them to generate 100% of their torque instantaneously.
Tesla Model X Gearbox
Tesla uses a Tesla drivetrain, meaning that Teslas have just a single gear when it comes to shifting, since they do not need any more than that.
This means that Tesla cars operate similarly to an automatic transmission found in conventional cars, with the exception of the lack of shifting. They have no multi-speed drivetrain, which means they have no conventional automatic, manual, or CVT gearboxes, as ICE-powered cars do.
Technically, Tesla cars have a single-speed drivetrain, which transfers power from the electric motors to the wheels, which allows the Tesla cars to drive. Teslas utilize electrical motors with two moving parts, as well as single-speed transmissions, which do not have any gears.
Because of how Teslas electric motors operate, all they require is one gear, since the Tesla Model S produces just enough torque to reach its maximum speed instantaneously.
Teslas operate on one gear, and they produce just enough torque to get the car to high revs instantaneously, and use this single gear the entire time until it hits its top speed. In short, electric cars, including Tesla models, are equipped with an automatic single-speed transmission, which requires only pressing down the throttle to go ahead.
You may find the shift levers in an electric car located at the manual-gear position, however, Tesla models provide the ability to select the gear through a lever located on the steering wheel.
Like many e-cars, Teslas Model S does not require many automotive components including transmission, gears, and clutch. Powertrain components include a permanent magnet switching-reluctance motor, an inverter, a battery pack, high-voltage system, cooling system, a power conversion system with onboard charger and DC/DC converter, and the Tesla powertrain.
Model Xs long range comes standard with two electric motors one on the front axle and one on the back which allow for four-wheel-drive capabilities.
The Tesla Model S uses two modes of transmission, which are Front-Drive and Rear-Drive. Front-Drive Rear-Drive transmission. Overall Final Drive Ratio and Reverse gear are two types of transmission used in Tesla Model X and Model X plaid.
Unlike gasoline and diesel cars, which need several gears to move usable torque and power, the electric vehicle does not require any clutches or gears at all. With an electric motor, the speed goes up, torque goes down, and energy goes up, giving the Tesla all the juice it needs to achieve great acceleration, as demonstrated with the Model-3 going zero-to-60-mph in just 3.2 seconds.
