What is the speed in first gear?
1 Answers
The speed in first gear is the starting speed, typically ranging from 0-5 km/h. Below is a related introduction to the design objectives of first gear and considerations for shifting gears in a car: Design objectives of first gear: The first gear in a car is designed to meet the need for starting on the maximum allowable slope when the car is in motion or fully loaded. Additionally, starting in first gear provides the fastest acceleration and is the gear with the lowest maximum speed. Considerations for shifting gears in a car: When starting in first gear, shift to second gear when the speed is between 15-20 mph, maintaining the engine speed at around 2,000 rpm. Shift to third gear at 30 mph, keeping the engine speed at 2,000 rpm, and to fourth gear at 40 mph, maintaining the same engine speed. Shift to fifth gear when the speed exceeds 50 mph, with the engine speed reaching around 2,000 rpm. It is important to time the gear shift appropriately—neither too early nor too late. After shifting, the clutch should be engaged smoothly and promptly, and the shifting action should be swift to minimize the time spent shifting and reduce the loss of kinetic energy in the car.
