Can You Drive 70 MPH in 4 Wheel Drive?

Four-wheel drive (4WD) vehicles are designed to provide additional traction in challenging driving conditions. This feature is handy when driving off-road or in snowy or slippery conditions. However, many drivers wonder whether they can operate at high speeds, such as 70 miles per hour (mph), in 4WD mode. In this article, we will explore the capabilities of 4WD vehicles and determine whether driving at high speeds in 4WD mode is safe and recommended.

Understanding Four-Wheel Drive

Before discussing the speed capabilities of 4WD vehicles, it's essential to understand how this feature works. In a 4WD system, all four vehicle wheels simultaneously receive power from the engine. This feature provides increased traction and stability, especially in low-traction conditions. There are two main types of 4WD systems: part-time and full-time.

Part-time 4WD systems are designed for off-road use and require the driver to engage the system manually. Full-time 4WD systems, on the other hand, are always active and adjust power delivery to the wheels automatically. Both systems are designed to provide increased traction, but they differ in how they operate.

Can You Drive 70 MPH in 4WD?

The answer to this question is yes; you can drive at 70 mph in 4WD mode. However, there are several factors to consider before doing so. Here are some of the critical factors to keep in mind:

Vehicle Type and Condition

Not all 4WD vehicles are created equal. Some vehicles, such as high-performance trucks or SUVs, are designed to handle high speeds and may reach 70 mph in 4WD mode without any issues. However, other vehicles may not be suitable for high-speed driving in 4WD mode.

Additionally, the condition of the vehicle is crucial. Driving at high speeds could be dangerous if the 4WD system is not functioning correctly. It's essential to have your vehicle inspected regularly to ensure that all systems are working correctly.

Road Conditions

While 4WD vehicles are designed to provide increased traction and stability, they are not immune to the laws of physics. Driving at high speeds on slippery or icy roads is always risky, regardless of whether you are in 4WD mode. It's essential to adjust your driving speed based on road conditions and be aware of potential hazards.

Tire Type and Pressure

The type and condition of your tires are also essential when driving in 4WD mode. The tires must be suitable for road conditions and have the correct pressure. Tires that are underinflated or worn out can reduce the effectiveness of the 4WD system and increase the risk of accidents.

Driver Skill and Experience

Finally, the skill and experience of the driver play a significant role in driving at high speeds in 4WD mode. Understanding how the 4WD system works and how to operate the vehicle correctly is essential. Drivers should also be aware of their limitations and adjust their driving accordingly.

Is it Recommended to Drive at 70 MPH in 4WD Mode?

While it is technically possible to drive at 70 mph in 4WD mode, it is not recommended. Here are some reasons why:

Increased Fuel Consumption

Driving in 4WD mode consumes more fuel than in two-wheel (2WD) mode. This is because the 4WD system adds extra weight to the vehicle and increases drag. Driving at high speeds in 4WD mode can increase fuel consumption, leading to more frequent trips to the gas station.

Increased Wear and Tear 

4WD systems are designed to handle low-traction conditions and off-road driving. However, they are not designed for sustained high-speed driving. Driving at 70 mph in 4WD mode can strain the drivetrain and suspension, increasing wear and tear. This can result in expensive repairs and maintenance.

Increased Risk of Accidents

Finally, driving at high speeds in 4WD mode increases the risk of accidents. Even if your vehicle is designed for high-speed driving, moving at 70 mph in 4WD mode can increase the risk of rollovers, loss of control, and other accidents. It's important to drive at safe speeds and be aware of road conditions at all times.

Alternatives to 4WD Mode

If you need to drive at high speeds, there are alternatives to using 4WD mode. For example, you can switch to 2WD mode or use a different vehicle designed for high-speed driving. Additionally, you can adjust your driving habits to be more fuel-efficient and reduce wear and tear on your vehicle.


In conclusion, driving at 70 mph in 4WD mode is technically possible, but it is not recommended. Driving at high speeds in 4WD mode can increase fuel consumption, wear and tear on your vehicle, reduce maneuverability, and increase the risk of 

accidents. If you need to drive at high speeds, it's important to consider alternatives to 4WD mode and adjust your driving habits accordingly. Additionally, regular vehicle maintenance and inspections are crucial to ensure all systems work correctly and reduce the risk of accidents.
