Do New Energy Vehicles Have Transmissions?

For pure electric new energy vehicles, a transmission is not necessarily required, but a reduction gearbox is essential. Below is relevant information: 1. Classification of new energy vehicles: includes battery electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. Currently, plug-in hybrids have transmissions, while pure electric vehicles do not. 2. Electric drive system: Essentially a power system assembled from a power electronics box and a gear reduction mechanism. A single-speed reducer has a simple structure and is easy to implement, while a multi-speed transmission has a more complex structure and higher difficulty.

From my personal experience, whether new energy vehicles are equipped with a transmission indeed varies by model. Pure electric models, such as Tesla or BYD's pure electric series, do not have a traditional multi-gear transmission but instead use a single-speed reducer to fulfill the function. This design allows the electric motor to directly drive the wheels, resulting in an exceptionally smooth driving experience with no jerking during acceleration, making it ideal for city commuting or short trips. Additionally, this simplified structure reduces maintenance needs—you don't have to worry about changing transmission fluid or gear failures, just regular motor checks. However, hybrid models, like Toyota's hybrid versions or Ford's plug-in hybrids, often come with a transmission, typically an e-CVT type, which combines electric and fuel systems to automatically switch modes for optimal fuel efficiency. This makes them perform better on long-distance drives. Understanding this can help you balance driving comfort and maintenance costs when choosing a car.

I'm not very knowledgeable about cars, but when I bought a new energy vehicle last year, I specifically researched this issue. After consulting with car owners and sales personnel, I found that pure electric vehicles like XPeng or NIO don't have transmissions, and they drive as smoothly as scooters, accelerating instantly when you step on the pedal. In contrast, plug-in hybrid models such as Honda or Chevrolet's hybrid versions usually come with transmissions because they need to handle the switching between the engine and the electric motor. This made me consider my daily usage when choosing a car: if you only drive in the city, pure electric is more hassle-free and saves money with fewer trips to the repair shop; if you frequently drive on highways, hybrids with transmissions can be more fuel-efficient. Now that I'm driving it, it's incredibly smooth, and I regret not understanding these details earlier.

Over the years of repairing cars, I've frequently encountered issues with new energy vehicle transmissions. Pure electric vehicles like the Model S don't have traditional transmissions - their systems are simpler with fewer failure points, relying solely on reduction gears for torque conversion. However, hybrids like Lexus or Hyundai hybrids often come equipped with e-CVT transmissions, requiring regular maintenance checks on oil levels and mechanical wear. I've seen cases where improper operation by owners caused transmission slippage, requiring professional attention. Generally, pure EVs are easier to maintain, while hybrids require extra attention to their transmission systems for longevity. Remember, following the maintenance manual can prevent major issues.
