What is the actual fuel consumption of the Venucia T60?

The comprehensive fuel consumption of the Venucia T60 is 5.9-6.4L/100km. There are currently 5 models of the Venucia T60 on sale: the Zhixing Edition, Zhixiang Edition, and Zhixiang Edition have a comprehensive fuel consumption of 5.9L/100km. The Zhiguan Edition and Zhijin Edition have a comprehensive fuel consumption of 6.4L/100km. The above figures are NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 6.9-7.6L/100km. The specific factors affecting a car's fuel consumption are as follows: Vehicle weight: Larger and heavier cars tend to consume more fuel. Generally, a small family car with a 1.6L displacement and a weight of about 1.2 tons has a fuel consumption of approximately 7.5 liters (calculated under full load conditions), while an SUV weighing about 1.5 tons has a fuel consumption of around 8.5 liters. Different weights result in varying fuel consumption. Drag coefficient: Higher drag coefficients increase fuel consumption during driving. Cars with better aerodynamics have lower drag coefficients, which leads to lower fuel consumption. Economical RPM: During driving, the engine has an optimal torque output point where fuel consumption is minimized. Generally, small-displacement cars reach this point at around 70 km/h, while larger-displacement cars achieve it at about 100 km/h. Maintaining speed within this economical RPM range significantly reduces fuel consumption. Driving style: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before stopping at traffic lights can increase fuel consumption.

Brief Introduction to the Working Principle of ABS System

ABS system, also known as the Anti-lock Braking System, works on the principle that: During braking, the ABS system, based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve for the wheel that begins to lock up, keeping the braking force constant. If the wheel continues to lock, the normally closed output solenoid valve is opened. This keeps the braking state always at the optimal point, achieving the best braking effect and ensuring the highest driving safety. ABS, short for Anti-lock Braking System, functions to automatically control the magnitude of the braking force during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling while slipping (with a slip ratio of about 20%), ensuring maximum adhesion between the wheels and the road surface. The ABS system mainly consists of four components: wheel speed sensors, electronic control unit (ECU), hydraulic unit, and ABS warning light. The wheel speed sensors detect the motion state of the wheels, generating sinusoidal electronic pulse AC signals. These signals are then processed by a modulator, converted into digital signals, and transmitted to the electronic control unit. The electronic central control unit (ECU) receives input signals from the wheel speed sensors, calculates parameters such as wheel speed, vehicle speed, and slip ratio, and determines the wheel state based on the slip ratio, issuing control commands to the hydraulic unit. The hydraulic unit adjusts the pressure in the brake lines according to the control commands, with the adjustment process including pressure holding, pressure increase, and pressure decrease. The ABS warning light is used to alert the driver to any system faults. If the ABS warning light is on, it is advisable not to continue driving, as it indicates a fault in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it difficult for the driver to decelerate or adjust the vehicle's trajectory, posing significant safety risks.

What is the maximum wading depth of the Volkswagen Bora?

According to official information, the maximum wading depth of the Volkswagen Bora is 150mm. Common tire specifications include 205/55R16 and 195/65R15, with a body length of 4663mm, a curb weight of 1240-1320kg, and it is a four-door sedan. The maximum wading depth refers to the deepest water level a car can safely pass through. Generally, the maximum wading depth of sedans does not exceed 30cm, while SUVs have a higher wading depth, but it is still best not to exceed 50cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30cm, the Audi A4 has 32cm, the Volkswagen Sagitar has 30cm, the Land Rover Range Rover has 90cm, the Jeep Compass has 48cm, and the Highlander has 45cm. The maximum wading depth of SUVs is significantly higher than that of sedans. Generally, when a vehicle is wading, different measures should be taken depending on the water depth and the vehicle's characteristics, as follows: If the wading depth reaches the height of the exhaust pipe, it is relatively safe. Even if water enters the exhaust pipe, the pressure inside can expel the water. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the wading depth reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom, which may lead to circuit failures, damaging critical electrical components and preventing the car from starting normally. If the wading depth reaches the height of the air intake pipe, it is extremely dangerous. Driving directly into such water can cause the engine to stall immediately, leading to permanent damage or rendering the engine unusable.

How to Correct Steering When Turning Too Early or Too Late in Parallel Parking?

After turning the steering wheel too early, you need to control the speed well and observe the rear wheels in the rearview mirror. Turn the wheel back half a turn and continue to observe the right rear wheel. When the car is tilted and the left rear wheel enters the parking space past the upper left corner, straighten the steering wheel and continue turning left.
