Optimizing Efficiency: The One-Speed Gearbox in Electric Vehicle Propulsion 
Electric cars typically use a single-speed gearbox, also known as a direct-drive or fixed-gear transmission. This is because electric motors have a much broader torque range compared to internal combustion engines, allowing them to operate efficiently across a wide range of speeds without the need for multiple gears. Additionally, electric cars are inherently more efficient and require less maintenance compared to traditional internal combustion engines, which eliminates the need for complex multi-speed gearboxes. A single-speed gearbox simplifies the design, reduces weight, and improves overall efficiency, resulting in a smoother and more reliable driving experience in electric cars.
