The engine speed at 80 mph is between 1500 and 3000 RPM. Below is a comparison of vehicle speed and gear RPM, as well as an introduction to gear and RPM under different conditions: Comparison of vehicle speed and gear RPM: Starting in first gear, the engine speed is around 1000-1500 RPM; in second gear, the engine speed is around 1500-2000 RPM; in third gear, the engine speed is around 1500-2000 RPM; in fourth gear, the engine speed is around 1500-2000 RPM; in fifth gear, the engine speed is around 1500-3000 RPM. Gear and RPM under different conditions: When driving a manual transmission car, the gear should match the engine speed and driving speed. During high-speed cruising, the highest gear should be used to reduce the engine speed, which helps improve fuel economy. When overtaking, it is necessary to downshift in advance to increase the engine speed and wheel torque, which helps the driver overtake quickly.

Is a tire pressure of 270 normal for an SUV in summer?

A tire pressure of 270 means 2.7 bar, and 2.7 bar for an SUV's tires in summer is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5 bar. 2.7 bar is higher than the maximum value of the standard tire pressure, so it is not normal. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; It accelerates the wear of the central tread pattern of the tire, shortening the tire's lifespan; The vibration of the vehicle body increases, indirectly affecting the lifespan of other components; It causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body, which increases the load on the car during driving; The resistance to punctures decreases. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and the impact can cause internal cracks and bursts, leading to a blowout.

What are the reasons why the Nissan Sunny's keyless start cannot be detected?

The reasons why the Nissan Sunny's keyless start cannot be detected are, first, the car's battery may be dead, and second, the key fob battery may be dead. Replacing the key fob battery: Gently press the small switch on the back of the key fob to remove the mechanical key. Then, use the mechanical key to open the key cover by inserting it into the notch beside the key and gently prying it open. After removing the battery compartment cover, you will see the position of the old battery. It is recommended to use a small flat-head screwdriver for easier removal of the old battery. Ensure the new battery is installed with the positive side facing up. Reassemble the key cover and mechanical key, and confirm the key functions properly. Precautions for battery replacement: Do not use the wrong battery. The battery life of a smart car key is approximately one year. Battery consumption varies depending on the frequency of key use. Different distances of key usage will also affect the power consumption. Be very cautious when replacing the battery of a smart car key, as any mistake can burn out the circuit board inside the key.

Will Insurance Cover Cars Flooded in Heavy Rain?

Insurance will cover the damages, but only if the commercial auto insurance includes vehicle damage coverage. If the policyholder has purchased vehicle damage insurance, they can receive compensation for damages to parts of the car other than the engine after the vehicle is flooded by heavy rain. If the policyholder has both vehicle damage insurance and water ingress insurance, the insurance company will cover all damages caused by the vehicle being submerged in water due to heavy rain, including engine damage. Below are some precautions for driving in rainy weather: Reduce speed and drive cautiously: Regardless of the road width or surface conditions, always drive slowly in the rain, keep an eye on the distance between vehicles ahead and behind, and be mentally prepared to take emergency measures. Visibility is low in rainy conditions, and the vehicle's braking distance and other emergency performance metrics are reduced, so it's essential to slow down in advance, allowing enough time and space to handle any situation safely. Maintain a safe distance: Rainy weather obstructs visibility, so it's crucial to keep a safe distance from other vehicles, constantly monitor the distance to vehicles ahead and behind, and increase the following distance. Especially stay away from large vehicles: first, they can block your view; second, puddles that large vehicles can pass through may not be passable for smaller cars, and large vehicles tend to splash water, which can interfere with smaller cars' driving.
