Introduction to the 4WD System of the Touareg

[DiHolden]

Here is the introduction to the 4WD system of the Touareg: 1. Part-time 4WD: Part-time 4WD is a four-wheel drive system where the driver can manually switch between two-wheel drive and four-wheel drive. The driver can achieve two-wheel or four-wheel drive by disconnecting or connecting the transfer case according to driving needs. This is the most common four-wheel drive system for off-road vehicles or SUVs with 4WD capabilities. 2. On-demand 4WD: On-demand 4WD is a system that only engages four-wheel drive when necessary, remaining in two-wheel drive under normal conditions. Its introduction not only reduces the cost of manufacturing 4WD vehicles but also provides users with better fuel economy. Mainstream mass-produced SUVs like the Honda CR-V and Toyota RAV-4 are equipped with on-demand 4WD systems. 3. Full-time 4WD: Full-time 4WD means that all wheels are independently driven at all times while the vehicle is in motion. Full-time 4WD vehicles have superior driving fundamentals compared to two-wheel drive vehicles: better power, traction, improved driving experience, enhanced safety during aggressive driving, and greater stability. Therefore, this system is typically found in high-end SUVs such as the Audi Q7, BMW X5, and Mercedes-Benz GL.

During my last test drive of the Touareg, I specifically experienced its 4WD system. This generation's 4MOTION uses an electronically controlled multi-plate clutch, primarily operating in front-wheel drive for fuel efficiency under normal conditions. The sensors can instantly detect slippage and redirect power to the rear wheels. It can allocate up to 50% of torque to the rear axle, providing noticeably better stability when cornering in rain or snow. Once, I took a sharp turn on a slippery road without experiencing any understeer. The ground clearance is sufficient, and paired with the hill descent control, tackling mild off-road conditions like climbing dirt slopes is quite effortless. The most practical feature is the snow mode – last winter on icy mountain roads, the automatic power distribution responded faster than I expected, and the onboard computer also limits throttle input to prevent slippage. However, it's important to note that this isn't a hardcore off-road system with locking differentials; its main advantage lies in the safety assurance for urban commuting.

As a long-term owner, let me share my daily experience with the Touareg's 4WD system. Its biggest advantage is hassle-free operation. During city driving, it primarily operates in front-wheel drive mode, which is more fuel-efficient than permanent 4WD. The dashboard displays real-time power distribution. Once during heavy rain on the highway, when crossing waterlogged sections, I clearly felt the wheels being pulled back immediately upon slipping. When taking family trips and encountering muddy construction zones, the torque distribution becomes particularly responsive in off-road mode, with the rear wheels following the front wheels effortlessly. The manufacturer claims the electronic differential braking can simulate the effect of three differential locks - in reality, it does enable single-wheel escape during cross-axle situations. Owners who rarely use the system should occasionally activate it to maintain clutch disc flexibility. For its price range, this is a practical 4WD system with relatively fuel-friendly performance.

The core of the Touareg's 4MOTION system is BorgWarner's fifth-generation torque manager, with a response time within 0.1 seconds. Sensors monitor 150 data points, including wheel speed, steering angle, and throttle depth. In normal mode, the front wheels receive 95% of the power, while the rear wheels can get up to 50% when slipping. Off-road mode adjusts the ESP calibration, allowing appropriate wheel spin. It feels like invisible hands are adjusting the center of gravity when driving, especially stable during quick lane changes. The most impressive feature is its towing capacity—I've tested it pulling a 2-ton RV uphill without strain. However, note that the rear differential oil must be changed at 60,000 km, or it will affect torque distribution accuracy.

Just tested the Touareg's 4WD system over the weekend, focusing on its performance across different road conditions. On paved roads, you barely notice its presence, with fuel consumption differing by less than 0.5 liters compared to the 2WD version. However, on national highways after heavy rain, it provides noticeably better grip when cornering. I deliberately tested it on a gravel slope, and it climbed a 30-degree incline with just light throttle input, with the electronic slip control kicking in quickly. In snow mode, it actively increases idle speed and reduces gear shifts. Once in an icy parking lot, while rear-wheel-drive cars nearby were struggling for traction, the Touareg started smoothly. Northern owners are advised to opt for winter tires, as pairing them with the 4WD system doubles the safety factor. Note that the hill descent control must be manually activated, and speed should not exceed 20 km/h.

Having studied the 4WD system of the Teramont, its core lies in the multi-plate clutch center differential, which is lighter and more intelligent compared to mechanical systems. During daily driving, the power distribution switches seamlessly without noticeable transitions, and in fuel-saving mode, the driveshaft doesn't even rotate. What's particularly interesting is its intelligent torque distribution in corners—when turning left, it allocates more power to the right rear wheel, making mountain road driving exceptionally smooth. The manufacturer claims the rear wheels can receive up to 1800Nm of torque, which is more than sufficient for towing a small boat uphill. Compared to the Q5L, which shares the same platform, the Teramont is tuned more for comfort, with better vibration damping. For maintenance, it's crucial to regularly check the clutch fluid level, as prolonged low levels can trigger overheating protection. For a family SUV, this system strikes a good balance between safety and fuel efficiency.
