The terms all-wheel-drive, 4-wheel-drive and the system used on German SUVs and sedans, the Audi quattro, are often used interchangeably. There are, however, differences between these different systems that are worth mentioning so that you can understand the advantages of one versus the other.
All-Wheel-Drive and 4 Wheel-Drive: What are the Differences?
Let's begin with some definitions to get familiar with the different automotive concepts.
All-Wheel-Drive
Right from the start, all-wheel drive automatically engages on your vehicle. This is a type of transmission where the engine's power is sent to all four wheels.
It does not require direct intervention from the driver because it uses sensors that continuously monitor road conditions and adjust the power for each wheel as needed.
4 Wheel-Drive
The most common term for this system is “4x4” or “4WD.”
The four-wheel drive system distributes power evenly among the vehicle's four wheels.
What distinguishes this system from all-wheel-drive is primarily that the four-wheel-drive system may not be active at all times. It is controlled by the driver, who can choose to engage or disengage the system at will.
Four-wheel drive vehicles generally offer various driving modes that can be activated based on specific uses or unique road conditions.
Full-Time All-Wheel-Drive
What does full-time all-wheel drive mean?
Vehicles equipped with full-time all-wheel drive have power delivered to all four wheels. In short, each wheel receives the same level of power from the engine. This is known as permanent all-wheel drive, which creates a clear difference between full-time all-wheel drive and 4x4 systems.
There is also a difference between full-time all-wheel drive and rear-wheel drive. While the former distributes power to all four wheels, the latter sends power only to the rear wheels.
Thus, Audi's most reliable luxury SUVs are either rear-wheel drive or all-wheel drive.
Full-Time All-Wheel-Drive: Utility and Operation
Nowadays, full-time all-wheel drive is considered intelligent. For example, when the sensors on the vehicle detect an anomaly, the system provides the necessary effort to prevent you from swerving or spinning on the road.
This type of transmission offers increased traction, enhanced responsiveness, lower fuel consumption compared to a 4WD, ease of use, improved stability on icy or wet surfaces, better cornering, and overall safer driving behaviour.
The Audi Quattro System: Definition, Operation and Advantages
To give you a bit of background info, the quattro system first appeared in 1980. In Italian, “quattro” means “four,” reminding us that Audi vehicles are four-wheel-drive.
Even more effective than traditional all-wheel-drive systems, the Audi quattro is defined as a system that distributes power to all four wheels in an extremely intelligent manner.
Audi’s innovative technology and cutting-edge engineering are evident in the quattro system. More than just a transmission system, the quattro drive offers an unprecedented driving experience.
The system's variable distribution of torque between the front and rear wheels delivers power with precision when needed. This transmission is not only intelligent, but also somewhat strategic.
With this system, vehicle guidance is enhanced. It allows you to negotiate curves more easily and improves overall handling.
At high speeds, the optional rear sport differential sends power to the outer rear wheel during turns, allowing that wheel to rotate faster and providing enhanced cornering performance.
In short, the Audi quattro is an ingenious system that has proven its worth. It is found on both Audi sedans and SUVs. Moreover, the e-quattro system found on Audi electric vehicles is equally impressive.
Which SUV to Choose with Full-Time All-Wheel-Drive?
Ultimately, the best full-time all-wheel drive is found in Audi vehicles. It is efficient, safe, high-performing, and agile, making it ideal for both full-time all-wheel-drive SUVs and the brand's luxury cars.
There is no doubt that Audi has a proven technological advantage over other vehicles in the industry.
A test drive will quickly convince you of the reliability and precision of the Audi quattro system. Discover models such as the A5, Q3, Q4, Q7, and Q8.
