E mode is the economy mode, while P mode is the power mode, so E mode is more fuel-efficient. Related introduction about the differences between E mode and P mode: Different modes: P mode is the fast mode or heavy-duty operation mode, while E mode is the economy mode. Different usage scenarios: P mode is mainly for heavy workloads, while E mode balances both workload and fuel consumption. Different energy consumption: In P mode, both engine speed and pump flow are high, resulting in relatively higher fuel consumption. In E mode, the main pump flow is partially reduced to pursue lower fuel consumption, making it the general working mode. It can be adjusted according to different load conditions to regulate engine output torque, thereby reducing fuel consumption. Details are as follows: E mode: This is the economy mode, suitable for trucks when they are empty or lightly loaded. It does not require the engine to output full power, achieving fuel efficiency. B mode: This is the standard mode, suitable for trucks under half-load or general load conditions, balancing between power and economy. P mode: This is the power mode, suitable for trucks under heavy loads or when climbing slopes, requiring maximum power output to ensure the truck's performance.

As a veteran driver with over a decade of experience, let me tell you that the E mode is designed for fuel efficiency. When driving in the city, switching to E mode makes the throttle response a bit slower, the acceleration smoother, and the transmission shifts less frequently, keeping the engine in its efficient operating range, which naturally reduces fuel consumption. In contrast, the P mode unleashes more power, providing quicker acceleration and a thrilling ride, but it significantly increases fuel usage—I've tested it and found it can burn up to 15% more fuel, especially on mountain roads or highways. Fuel efficiency isn't just about the driving mode; driving habits are also crucial—avoid sudden braking and rapid acceleration, and maintaining a steady speed on highways works well. Weather and tire conditions also play a role. In summer, using E mode with the air conditioning on is ideal. Don’t chase the thrill of P mode’s extra push—saving money and staying safe is the way to go.

How to Claim Insurance for a Flooded Sedan?

If your car is flooded, you must not start the engine again. This is because forcibly starting the car after the engine has been flooded can cause further damage to the engine. After the car is flooded, the owner should contact all auto insurance customer service as soon as possible (within 24 hours) to file a claim and have the vehicle assessed for damages before proceeding with the claim. Take photos of the flooded car for documentation. Additionally, it is advisable to keep a copy of a newspaper reporting the heavy rain on that day or any other proof that can verify the weather conditions. Both insurance companies and 4S shops offer towing and rescue services, but during severe weather, towing services may be in high demand.

What are the reasons for high idle speed in small cars?

Small cars have high idle speed for the following reasons: 1. High idle speed causes: When the engine water temperature is low, the air conditioning is on, or the engine voltage is low, the ECU program is designed to appropriately increase the idle speed, which is normal. If the engine water temperature is normal, the air conditioning is off, and the idle speed is still high, it indicates a system malfunction, which could be either in the electronic control system or the mechanical system. 2. Mechanical faults: For mechanical faults causing high idle speed, it is essential to check for air leaks in the intake pipe, detached or damaged vacuum tubes, or damaged intake pipes. The intake manifolds of Volkswagen engines are mostly rubber pipes. During idle, the engine intake air volume is minimal, and any air leaks can result in high idle speed.

What Causes a Diesel Vehicle Not to Consume Urea?

It may be due to the SCR system not functioning properly. Here are the relevant explanations: 1. Working Principle: When nitrogen oxides are detected in the exhaust pipe, the urea tank automatically sprays diesel exhaust fluid (DEF). The DEF and nitrogen oxides undergo a redox reaction in the SCR catalytic converter, producing non-polluting nitrogen and water vapor that are then expelled. 2. Automotive Urea: The technical name is diesel exhaust fluid (DEF), used in diesel engines. There is an integrated chip control between the engine and the urea tank, which determines the amount of DEF to inject based on the engine's power output. Currently, if the system is clogged and unable to spray DEF, it will result in reduced engine power and performance.

Does the Electronic Parking Brake Act on the Front or Rear Wheels?

Electronic parking brakes act on the rear wheels. Here is more information about electronic parking brakes: 1. The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both achieving control of parking braking through the friction generated between the brake disc and brake pads, except that the control method has changed from the previous mechanical handbrake lever to an electronic button. 2. The electronic parking brake has evolved from the basic parking function to include an automatic parking function. The application of automatic parking technology eliminates the need for drivers to maintain prolonged braking when the vehicle is stopped. When the automatic electronic parking brake is activated, it can prevent unnecessary sliding of the vehicle.
