The wading depth of the Buick Excelle is generally half the height of the tires. When the water depth is one-third of the tire height, you can pass through safely as long as you operate correctly, avoiding unnecessary damage. However, if the water depth exceeds half the tire height, caution is required as it may lead to water entering the vehicle. If the wading depth surpasses the bumper, you should remain vigilant to prevent water from entering the engine. Below are some tips for driving through waterlogged areas during rainy weather: 1. When encountering waterlogged roads while driving, slow down or stop to observe. If the water level reaches the bumper or two-thirds of the tire height, proceeding poses certain risks. High speed increases the actual wading depth, potentially allowing water to enter the cabin through the engine compartment or chassis. Avoid driving against waves caused by large vehicles. If the water level is high, detour if possible rather than forcing your way through. 2. While wading, maintain a low speed: avoid stopping, shifting gears, or accelerating. Instead, drive steadily at a low gear with moderate throttle to pass through smoothly without creating large splashes. 3. If the car stalls in water, do not attempt to restart it immediately: arrange to have the vehicle towed to a safe location with less water as soon as possible. Severe engine water ingress can occur if water enters through the air filter into the intake valve and then the cylinder. Attempting to restart may cause deformation of critical components like the crankshaft and connecting rods, leading to engine vibration or even breakage. If the engine stalls in water, it likely means water has entered, and the vehicle should be towed in neutral to a repair shop for cleaning. 4. After wading, promptly remove moisture from the brake pads: drive at low speed while lightly pressing the throttle and brakes. If you're not comfortable doing both simultaneously, press the brakes multiple times at a slow speed to generate friction heat, which helps evaporate the moisture.

The Buick Excelle's wading depth is generally around 250mm to 300mm, approximately up to half the height of the wheels. As someone who drives it daily for commuting, I once encountered floodwaters during a heavy rainstorm. I drove through slowly with water about 25cm deep, and the car had no issues. However, I must remind everyone not to go too fast, as water rushing into the exhaust pipe can cause the engine to stall. I've also observed fellow drivers' experiences: if the engine hasn't been modified and the air intake is in a lower position, it's prone to water ingress when the water level rises, and repairs can be costly. Regularly check the vehicle's undercarriage and sealing rings to prevent rust and extend its lifespan. In summary, when encountering deep puddles in urban driving, assess the surroundings first before deciding. Safety is paramount—if the water exceeds this depth, turn around and find an alternative route.

The Buick Excelle's wading depth is approximately 25 to 30 centimeters, which is related to the design of the vehicle's intake system. I often tinker with cars and have studied its manual. When driving normally, you should be cautious if the water depth exceeds the centerline of the tires, as excessive water pressure may damage electronic components. It is recommended to maintain a low and constant speed when wading, avoiding sudden acceleration or braking to reduce the risk of water splashing into the intake pipe. Additionally, after rainy days, don't forget to check if there is any moisture residue in the air filter, as it can accelerate engine wear. Although the car can handle this depth, it's best not to test it, as it could be troublesome if the water depth is unpredictable.

Safety should always be the core of driving. The Buick Excelle has a wading depth of approximately 250mm, but I don't recommend casually challenging this limit. Water that's too deep can cause electrical system short circuits or engine stalling, especially during heavy rain when the depth of puddles is unclear—it's best to detour. After wading, immediately check for signs of water seepage inside the car, such as damp carpets indicating potential sealing issues, and address them promptly to avoid corrosion. Remember, wading depth is just a reference value; actual driving should consider water flow speed and road conditions. Novices should avoid such hazardous scenarios.
