True and false advertisements, why do those car owners who bought four-wheel drive regret it?

In fact, the four-wheel drive, to put it bluntly, is a four-wheel drive, and the engine can evenly distribute the output power to four wheels. For example, in today's cold weather, if the road is frozen, if several wheels slip when you are driving, as long as one wheel is stuck, then the engine will automatically transfer power to this wheel, greatly improving the passability. Everyone generally says that this model is a four-wheel drive, but there are three types of four-wheel drive, so we need to popularize science here. Four-wheel drive is divided into part-time four-wheel drive, full-time four-wheel drive and timely four-wheel drive. These models are still very common in China. Let's not evaluate the quality of technology here, let's talk about each driving mode.

Part-time four-wheel drive, also known as part-time four-wheel drive, is worth mentioning. Cars can drive on two or four wheels according to road conditions and change themselves. There are Jeep herdsman, Landwind X8 and Nissan paladin in China. This is also a common driving mode of off-road vehicles.

Full-time four-wheel drive performance is better. Each wheel hub of a car is driven independently. It distributes the driving capacity to each tire through a flexible differential, and connects the differential (independent) of the front and rear axles. Moreover, this design is also widely used in major racing cars and performance cars, from the earliest Subaru and Mitsubishi to the famous Audi Quattro, all of which are representatives of strong performance.

This four-wheel drive mode will only change under certain conditions, and it is only two-wheel drive under normal circumstances, which means that this driving mode is completely controlled by computer and can only play its greatest role in an emergency. The models equipped with timely four-wheel drive include Honda's CR-V, Subaru's Forester and Nissan Hacker.
