What is the normal range for an automatic car's tachometer?
1 Answers
An automatic car's tachometer reading of 2000 RPM is normal. For automatic transmission vehicles, when the speed reaches 20 km/h, you can shift to 2nd gear when the RPM is between 1500 and 2000; when the RPM exceeds 2000, shift to 3rd gear, which is close to 30 km/h. Similarly, shift to 4th gear when the speed reaches 50 km/h. The gears in an automatic car include: 1. D (Drive) gear: Also known as the driving gear, mainly used when the car is moving forward; 2. S (Sport) mode: Suitable for highway driving or overtaking, the S mode and D mode are two driving modes of the car. In S mode, the car's automatic gear shifting is delayed; 3. L (Low) gear for downhill driving, suitable for automatically controlling the car's speed when going downhill.
