What is the wading depth of the Regal?
2 Answers
The maximum wading depth of the Regal is 325mm. The wading depth of the Regal is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact cars and small cars with low chassis, the position of the vehicle's air intake should be used as a reference when passing through waterlogged roads. If the air intake is below the water level when the Regal is wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause serious damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. Alternatively, the height of the engine's air intake (i.e., the maximum wading depth) can be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before the vehicle enters the water, the auto start-stop function must be turned off to prevent the engine from automatically restarting after stalling in the water, which could cause severe damage due to water ingress. Assess the underwater road conditions based on the passage of preceding vehicles and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. For roads prone to water accumulation, observe warning water level markers, trees, or other vehicles' wheels and doors as reference points to judge the water depth before deciding whether to proceed. Understand your vehicle's safe wading depth. If the water depth exceeds half of the tire height or the engine's air intake, do not enter the water recklessly. Instead, choose an alternative route.
I've been driving my Regal for several years and have encountered heavy rain and waterlogged roads a few times. For sedans like the Regal, the wading depth is generally around 300 to 400 millimeters, which is roughly up to the halfway point of your wheels. I once drove through a deeper section and almost got water in the engine—it was terrifying. During heavy rain, I always check the water depth beforehand. If the water level exceeds the bottom of the door sill, I take a detour. When wading through water, drive slowly and avoid slamming the accelerator, as sudden surges can cause water to rush into the exhaust pipe and stall the engine. If you're unsure about the water depth, use a stick to measure it. If it exceeds the safe limit, don’t take the risk. After driving through water, promptly check the undercarriage and air filter to prevent mud and debris from clogging and affecting future drives. Developing these habits can save you a lot of repair headaches.
