Are the driving wheels and passive wheels the front or rear wheels respectively?

Driving wheels are the front wheels, and passive wheels are the rear wheels. The driving wheels of a car are the wheels connected to the drive axle, providing the power for the car to move forward. After the power from the car's engine is transmitted through the gearbox, it is transferred to the driving wheels via the drive axle. Therefore, the drive axle not only supports the weight of the car but also provides the driving force. When the car moves forward, the driving wheels are the two front wheels, while the two rear wheels serve as the passive wheels, which only support the car without providing any driving force. Below is additional information about car drivetrains: 1. Car drivetrain configuration: Refers to the arrangement of the engine and the number and position of the driving wheels. The most basic classification is based on the number of driving wheels, which can be divided into two-wheel drive and four-wheel drive. Most vehicles have front and rear rows of wheels, with the wheels directly driven by the engine to push (or pull) the car forward being the driving wheels. The drivetrain configuration significantly impacts the vehicle's performance, appearance, internal dimensions, weight, axle load distribution, manufacturing cost, and maintenance. Scientifically and rationally selecting the drivetrain configuration is one of the primary tasks in automotive design. 2. Front-engine, rear-wheel drive (FR): Also known as front-engine rear-wheel drive, it is a traditional drivetrain configuration. In this setup, the front wheels are responsible for steering, while the rear wheels handle the driving. In this configuration, all the engine's power is delivered to the rear drive axle, driving the rear wheels to move the car forward.
Over the years of driving, I've noticed whether the driving wheels and passive wheels are the front or rear depends on your car type. Most regular sedans are front-wheel drive, meaning the front wheels propel the car forward while the rear wheels just roll passively. For example, in front-wheel-drive cars like the Honda Accord or Volkswagen Jetta, the engine output directly drives the front wheels, with the rear wheels merely providing support. But if you're driving a rear-wheel-drive vehicle like the BMW 3 Series or Ford Mustang, then the rear wheels become the driving wheels that deliver power, while the front wheels handle steering. Passive wheels typically refer to those without direct power, and you should pay attention to even tire wear during maintenance. This design affects handling feel - front-wheel-drive cars may slip less in snow, while rear-wheel-drive cars are more suited for drifting. Four-wheel-drive systems are an exception, as they involve power distribution between wheels - just choose according to road conditions when selecting a car.
As an automotive enthusiast, I love studying chassis layouts. The driven wheels are where the engine power is transmitted to propel the vehicle; passive wheels have no active power source and simply follow along. In front-wheel-drive configurations like the Toyota Camry, the front wheels drive while the rear wheels are passive; in rear-wheel-drive vehicles such as the Mercedes-Benz C-Class, the rear wheels drive and the front wheels are passive. Some four-wheel-drive modes also exhibit similar dynamic contrasts. The position of driven wheels affects weight distribution and handling response, with rear-wheel drive potentially offering better cornering performance. Passive wheel systems are simpler but often overlooked in maintenance, requiring regular checks on steering and suspension. Modern hybrid systems sometimes blur these distinctions, but the fundamental concepts remain clear. Remember, consulting the vehicle manual or inspecting the driveshaft can quickly clarify the configuration.
