Many people do not know the drivetrain of their cars and confuse the 2WD with the 4WD. However, a 2WD can be FWD or RWD, but the 4WD has no categories.
How Do You Know If Your Car is 2WD or 4WD? You can check if your car is 2WD or 4WD with power distribution to tires, number of differentials, checking the VIN or owners manual, link of the axle shaft, engine mounting position, different traction levels, variable speed at corners, and non-identical fuel economy.
The 4WD drive cars have better traction on different roads because of the equivalent force distribution to all tires. But, 2WD vehicles utilize reduced energy for spinning the driving wheels.
How do I know if my car is 2WD or 4WD?
You can differentiate between 2WD and 4WD cars by the rotations of their tires. However, I have explained different techniques to identify whether they are 2WD or 4WD.
Power distribution to tires
You can differentiate the 2WD and 4WD cars by identifying the power distribution to their tires. You can check their front and rear tires and find the axle shaft.
It indicates that the driving power distributes to two or four tires. The power distributed to two tires makes them drive tires and makes them 2WD.
However, the driving force distribution on all four tires shows that they are 4WD. The front and rear axle shows that they are 4WD, and you can identify them because of the dual axles.
You can go underneath the frame, identify the axles and check their rotations through a driving test. The tires that push the vehicle forward are driving wheels.
Two driving wheels with maximum driving force make it 2WD. Moreover, the force distribution to four tires makes the vehicles 4WD.
The axle shaft interacts with the built-in differential to spin the driving wheels.
Number of differentials
The car differential is underneath the frame and identifies it because of the specific design. The differentials are narrow from the corners and have more widths near the edges.
They can spin the wheels at different speeds because of their standard mechanism. You can identify one differential on the 2WD cars because of their designs.
The differential is between their rear and the front axle. In such circumstances, the drive shaft delivers the power to the differential.
Then, it sends the force to each driving tire, which makes the vehicle 2WD. 4WD vehicles have dual differentials and differentiate them from 2WD models.
It makes their identification less challenging and consumes minimum time. The two differentials deliver driving force to all tires.
In such circumstances, you can identify them as 4WD because of these specifications. All wheels have equivalent power and spin at a standard speed.
Use the VIN and owners manual
You can identify a 2WD car by using its vehicle identification number. Opening the website of your car is better for quick identification of the drive mode.
Also, you can enter the VIN in the information search bar and check the wheel drive section. It is better to examine the dimensions of your vehicle engine by checking the vehicle identification number.
The eighth digit shows the engine codes and indicates the wheel drive. Furthermore, you can use the manual of your 4WD car and check its information.
A few AWD cars have a logo on the frame’s rear side, which makes its identification less time-consuming.
However, you cannot check its manual for better results because the logos and stickers are available in the market.
A few people stick them on used vehicles that are not AWD, which reduces driving safety.
Link of the axle shaft
You can identify a 4WD car with its link of axle shaft with the wheels and their knuckles. These are metallic-based shafts that link to the middle part of the knuckles.
They have cylindrical shapes because of their standard manufacturing layouts. You can find a rubber-based cone-shaped guard on the edge of the metallic shaft.
The rubber-based come attaches with the knuckles, which makes the car 4WD. Also, an axle is a metallic rod known as a shaft. It has a direct link with the driving wheels.
The axle shaft attaches to two driving tires of a car, and you can examine it by going underneath the frame. It makes the vehicles 2WD because the axle or shaft has a link with the driving tires.
The shaft can deliver force to these two tires, which spin at identical speeds.
Engine mounting position
You can identify that the car is 2WD or 4WD by the engine mounting positions. However, the 2WD cars have the engine on the front side of the frame because of the standard specifications.
These vehicles have rear or front-wheel drive due to stock layouts. You can identify their engine on the front side of the axle and force spins the two wheels.
A few vehicles have the engine on the rear side, which indicates the rear-wheel drive system.
Moreover, four-wheel drive vehicles have the engine on the rear side but before the mount of the built-in rear axle.
You can check the engine mount and differentiate these vehicles.
Different traction level
You can check the car’s traction on rough terrains and during off-road driving conditions. A few models have reduced traction during off-road driving and on rough terrains.
They have low stability because only two wheels can push the vehicle forward. These wheels are driving tires and have less stability for rough and uneven terrain, which indicates their low traction level.
In such circumstances, these 2WD cars have minimum stability during off-road driving conditions. You can identify the 4WD models with a driving test on uneven and slippery surfaces.
They are more stable and provide high traction on uneven terrains.
The variable speed at corners
The 2WD cars have better speed and stability on the corners and turn. You can drive them at higher speeds on the corners because their driving wheels push the vehicle forward at this acceleration level.
However, the 4WD models take more time at the corners and turn. Driving them is challenging on the corners because their drive wheels require more time to change their direction.
Their tires lose stability and take more time to recover. You can identify the 4WD variants at the corners because driving both axles at the maximum speed is challenging.
Non-identical fuel economy
Identifying the 2WD and 4WD cars is less challenging by checking the fuel economy. Various factors can affect the car’s fuel economy, but it is a determining factor of the drive wheels.
The engine delivers the driving force to two wheels on a 2WD car and requires less power for this power distribution. Therefore, these vehicles have a higher fuel economy.
In contrast, 4WD car engines deliver the driving power to all four tires, which increases fuel consumption. It increases their fuel economy and makes them 4WD.
In such circumstances, their identification becomes less challenging.

| Features | 2WD Cars | 4WD Cars |
| Wheel force distribution | Two wheels | Four wheels |
| Traction | Less | More |
| The speed at corners | High | Low |
| Fuel economy | High | Low |
| Differentials | One | Two |
| Expensive | Less | More |
How do I know if my car is front-wheel drive?
The car engine delivers power to the axles, which send the force to the driving wheels because of the connection points. You can see the axle position and connection with the vehicle tires.
The axle connects with the front tires knuckle showing that the car is front-wheel drive. Also, these are driving wheels and essential parts of drivetrains.
You can check the engine mounting position on your automobile and identify the drive wheel. The front wheel drive cars have the engine in the transverse position on one side.
Their differential has a cylindrical assembly and specific housing. The housing delivers force to the shaft and wheels.
In addition, the front housing indicates that the vehicle is front-wheel drive.
