1 Answers
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.
