How to distinguish front-wheel drive from rear-wheel drive by appearance?

Generally, rear-wheel drive vehicles use longitudinally mounted engines. Vehicles with shorter front ends are usually not rear-wheel drive. If the chassis is visible, you can determine whether it is rear-wheel drive by checking for the presence of a driveshaft on the rear wheels. The main differences between front-wheel drive and rear-wheel drive are as follows: 1. Different driving methods: Front-wheel drive is when the engine drives the front wheels, pulling the entire vehicle forward; rear-wheel drive is when the engine drives the rear wheels, pushing the entire vehicle forward. 2. Price difference: Front-wheel drive vehicles are cheaper to manufacture and more economical, but they are prone to understeer, causing the driver to experience "pushing" in turns. Rear-wheel drive vehicles are slightly more expensive but offer more agile handling and greater torque, though they tend to oversteer. 3. Fuel consumption difference: Rear-wheel drive vehicles have a driveshaft and an additional differential, which results in power loss and reduced efficiency. Therefore, rear-wheel drive vehicles consume more fuel than front-wheel drive vehicles.
First trick: Observe the body proportions. Rear-wheel-drive cars usually have a longer front end because the engine needs to be placed longitudinally and space must be made for the driveshaft. Just like the sleek front end of sports cars, most of them are rear-wheel drive. Front-wheel-drive cars have a shorter front end, and you can feel much more spacious front seating, especially noticeable in A-segment cars. Additionally, the length of the rear door can reveal the secret—rear-wheel-drive cars often have rear doors that are shorter than the front doors, while front-wheel-drive cars have longer rear doors. The position of the tires also matters; the rear wheels of rear-wheel-drive cars are often tucked deeper into the wheel arches, giving the whole body a proportion like an athlete's inverted triangle shape. Of course, many cars nowadays are designed to look more and more alike, so these characteristics aren't absolute.
My favorite way to determine the drivetrain is by crouching down to inspect the underside of the car. The raised driveshaft tunnel running along the center of the chassis is a dead giveaway for rear-wheel drive (RWD) vehicles, stretching from the front seats all the way to the rear axle—its presence almost certainly means it's RWD. In contrast, front-wheel drive (FWD) cars have a much flatter underbody without that prominent bulge. Tire wear patterns also reveal clues: RWD cars typically show significantly more wear on the rear tires, especially high-performance models that go through rear tires much faster. The exhaust pipe layout at the rear offers hints too—RWD models often feature a dual exhaust system emerging from the center of the underbody, unlike FWD cars where the exhaust pipes route directly from the front. However, this method doesn't hold up well with electric vehicles, as these traditional telltale signs don't apply to EVs.
