Q5 is a front-mounted four-wheel drive vehicle, and there is no need for manual operation to switch the car from two-wheel drive to four-wheel drive via buttons. Its front-mounted four-wheel drive system will automatically analyze road conditions to switch the driving state between two-wheel drive and four-wheel drive modes. Taking the 2020 Audi Q5 as an example, it belongs to the medium-sized SUV category, with body dimensions of: length 4753mm, width 1893mm, height 1659mm, wheelbase 2908mm, and a fuel tank capacity of 73 liters. The 2020 Audi Q5 features a five-link independent suspension in the front and a five-link independent suspension in the rear. It is equipped with a 2.0L turbocharged engine, delivering a maximum horsepower of 190PS, maximum power of 140kW, and maximum torque of 320Nm, paired with a 7-speed dual-clutch transmission.

I've been driving an Q5 for three years, and its quattro system doesn't require manual switching at all. During normal city driving, it operates in front-wheel drive mode for better fuel efficiency. However, if the tires slip or the system detects the need for more power, it can switch to all-wheel drive in just 0.2 seconds. There's a driving mode selector knob on the steering wheel - turn it to off-road mode, and the quattro system will intervene more aggressively, even automatically locking the differential when descending steep slopes. It provides exceptional stability on highways during rain or snow, though remember to turn off the ESP stability control system to maximize its off-road capability. Actually, this quattro ultra system automatically disconnects the rear axle driveshaft when driving above 40 km/h, and automatically re-engages when speed drops below 35 km/h or during sudden acceleration.

I've studied Audi's four-wheel-drive system. The Q5 uses the quattro ultra electronically controlled four-wheel drive, which automatically switches without the need to press any buttons. If you want more power to the rear axle, find the driving mode selection on the center console and switch to dynamic mode or personalized settings. The instrument panel will display the power distribution status of all four wheels. During high-speed cruising, typically only 5% of the power is allocated to the rear wheels. When wading through water, it's best to manually shift to M mode and lock in a lower gear in advance to prevent the transmission from automatically upshifting and interrupting power. If you frequently drive on rough roads, it's recommended to install the original off-road optional package, which raises the chassis by 30 millimeters.

Attention to drivers of the new Q5, the quattro system operates fully intelligently. Every time you start the vehicle, it defaults to Auto mode, with the system constantly monitoring wheel slip. If you want manual control, there's a drive mode button next to the gear selector—just choose the off-road mountain icon. I tested it on icy roads last winter, and the system can transfer 90% of power to the wheels with traction in just 150 milliseconds. For daily driving, there's no need to worry about switching modes—it automatically shifts to two-wheel drive for fuel efficiency in traffic and instantly engages quattro when you floor the accelerator.

My colleague's Q4 all-wheel drive switching is particularly simple, with a circular mode knob located in the lower left area of the steering wheel. When turned to the right towards the off-road symbol, the system pre-distributes power and adjusts throttle response. Pay special attention to the drive status diagram in the center of the instrument panel: blue indicates front-wheel drive, while yellow represents activated all-wheel drive. Remember to enable the hill start assist function in the MMI settings to ensure full-time all-wheel drive intervention during steep hill starts. It's best to turn off the auto start-stop feature when driving on muddy terrain to prevent temporary power interruption.

As an auto mechanic frequently working on the Q5, the core of its four-wheel-drive switching lies in the central multi-plate clutch. The system monitors wheel speed differences 100 times per second, with the normal mode favoring front-wheel drive for fuel efficiency. To forcibly engage four-wheel drive, press the drive select button on the center console to choose dynamic mode, where power is distributed at a 40:60 ratio. When encountering sandy terrain, don't hesitate—shift directly to S mode to raise the RPM and activate four-wheel drive. Here's a hidden trick: press and hold the ESP button for 5 seconds to enter the off-road menu, where you can lock the hill descent control function.
