Why is Audi Called Fake Four-Wheel Drive?

[EleanorRose]

Currently, Audi's Quattro four-wheel drive system is divided into two forms: one is the on-demand four-wheel drive, and the other is the full-time four-wheel drive. The on-demand four-wheel drive system can be understood as a castrated version of the mechanical Quattro system, where the rear differential adopts a multi-plate differential, resulting in reduced performance. Therefore, this Quattro system using a multi-plate clutch is referred to as "fake four-wheel drive". The differences between on-demand four-wheel drive and full-time four-wheel drive are as follows: 1. Different working modes: On-demand four-wheel drive operates mostly in front-wheel drive mode. When the vehicle detects wheel spin, it uses brakes, ABS, and other means to brake the spinning wheel, thereby transferring power to the opposite wheel to help the vehicle escape. Full-time four-wheel drive, on the other hand, maintains a four-wheel drive state all the time, which greatly enhances vehicle stability. 2. Different differentials: On-demand four-wheel drive uses a multi-plate differential, while full-time four-wheel drive employs a purely mechanical Torsen differential lock, which is superior in both performance and reliability.

As an automotive technology enthusiast, I've always felt there's some truth to the claim that Audi's quattro all-wheel drive is a 'fake' system. The main reason is its use of the quattro ultra system, which automatically switches to front-wheel drive on dry roads to save fuel. However, in emergencies like snow or muddy conditions, the torque distribution isn't as balanced as with traditional Torsen differentials, making it easy to criticize as an incomplete AWD system. This design is actually intended to improve fuel efficiency and reduce energy consumption, not to deceive. In real-world driving, I've experienced moments when turning in the rain where the rear wheels felt underpowered, which was slightly unnerving, but it does save significant fuel costs during daily commutes. I think people shouldn't just judge by labels - test driving at dealerships gives a more realistic understanding of its pros and cons. Safety should always come first.

Having driven Audi's S series for several years, the term 'fake quattro' reminds me of a few practical scenarios. For instance, on some mountain roads or during rapid acceleration, the power output tends to favor the front wheels, not as potent as the imagined full-time all-wheel drive. This stems from the quattro system prioritizing front-wheel drive for fuel efficiency. My experience is that driving is smooth in normal weather with low fuel consumption, but wheel slippage occurs more frequently on icy or snowy days, always feeling slightly lacking. This design is actually reasonable—Audi aims to balance environmental concerns and performance, but when user expectations are high, they call it 'fake.' I suggest owners not get too hung up on nicknames. Regularly check the system to ensure functionality, as driving safety is far more important than online reviews. When choosing a car, base your decision on your actual needs.

With over 20 years of car repair experience, I've encountered many Audi quattro owners complaining about 'fake AWD' issues. The common causes lie in system component failures, such as worn multi-plate clutches failing to engage all-wheel drive, resulting in uneven power distribution during rain or turns and mistakenly labeling the system as fraudulent. This nickname stems from the quattro ultra design prioritizing fuel efficiency over all-weather power output, which can easily cause misunderstandings. In practical use, electrical circuit problems and aging components are the primary culprits, preventable through regular maintenance. Remember, timely inspections at authorized shops ensure safety – don't believe exaggerated claims online.

As an Audi family user who drives a Q3 to pick up and drop off my kids, some people mock it as a 'fake all-wheel drive.' Their reasoning is that this AWD mode prioritizes fuel efficiency under normal conditions and only engages when slippage occurs, unlike other brands' full-time systems, hence the teasing. Personally, I find it quite practical—it significantly reduces fuel consumption on city roads and performs adequately on snowy winter roads. The design philosophy behind it is Audi's balance between economy and performance, not cutting corners. Those internet buzzwords exaggerate the issue; in actual driving, the system responds promptly, making it fully qualified for family use. Don’t misjudge its value based on nicknames—safe travel comes first.
