Four Wheel Dive - 4WD v All Wheel Drive - AWD
Published Date: 5th Jun 2023
Four-wheel drive (4WD) is a drivetrain system that delivers power to the four wheels of a vehicle, providing increased traction and control, particularly on slippery surfaces like snow, ice or mud, and off-road driving. This system employs a transfer case that splits torque output from the transmission into front and rear output shafts that distribute power to the respective front and rear axles. The transfer case is designed to be engaged only when the wheels slip, not to limit the vehicle's manoeuvrability on dry pavement while providing better handling in adverse conditions.
What is AWD?
Unlike traditional front or rear-wheel drive models, all-wheel drive (AWD) is a drivetrain system that connects all four vehicle wheels with the engine power. An AWD system is unique in its ability to adjust power distribution between front and rear wheels automatically. It provides exceptional grip on challenging surfaces while maintaining fuel efficiency on everyday roads.
When the rear wheels of a car have more grip, an AWD system will automatically shift additional power to the rear. It instils drivers with greater confidence when traversing through low-grip or slippery terrain and guarantees exceptional stability when navigating wet or damaged roads. AWD is ideal for people residing in areas with frequent high levels of rainfall or snowfall. Traction can easily be compromised; in that case, a reliable vehicle is a must.
What are the pros and cons of 4WD?
Pros:
- Better traction in slippery conditions
- Better off-road performance
- More control in slippery conditions
Cons:
- Worse fuel economy
- More expensive to purchase and maintain
- More complex to repair
Pros and cons of 4WD:
Pros:
- Better traction in slippery conditions
- Good fuel economy on dry roads
- Easy to use
- Less expensive to purchase and maintain
- Simpler to repair
Cons:
- Not as good off-road as 4WD
- Not as much control in slippery conditions as in 4WD
Which system is right for you?
The choice of the best driving system depends on both your individual needs and your driving practices. If the weather is generally clement and you stick to paved roads, opting for an AWD model suits you perfectly; however, if you often venture into areas with ice or snow or take to off-road trails, a 4WD system is the better choice.
The accompanying table summarises the key differences between 4WD and AWD systems. 4WD is consistently engaged, while AWD can be disengaged or engaged as needed. Typically, 4WD is used in trucks and off-road vehicles, while AWD is commonplace in SUVs and cars. Four-wheel drive delivers superior off-road performance, while AWD provides better traction in slippery conditions.
The table shows the key differences between 4WD and AWD systems. 4WD is always on, while the driver can engage or disengage AWD. 4WD is typically used in trucks and off-road vehicles, while AWD is more common in cars and SUVs. 4WD provides better off-road performance, while AWD provides better traction in slippery conditions.
