How Fast is an Automatic Car Generally at 2000 RPM?

When the RPM reaches 2000, the speed is generally around 80 km/h. Factors affecting the car's RPM include: 1. Engine mechanical transmission structure; 2. Mechanical transmission resistance; 3. Combustion system supply; 4. Vehicle load. Relevant explanations about car RPM are as follows: 1. Normal cold idle speed is generally around 950-1300 RPM, but there may be some variations between different models; 2. Starting at 1200 RPM is more suitable on regular roads. For climbing or when the vehicle load is relatively high, the RPM can be appropriately increased. It's best to warm up the engine before starting in winter, usually for about one minute. The starting RPM should preferably not exceed 2000, as it may adversely affect the engine; 3. The idle speed of a car, whether cold or hot, is unrelated to the transmission position. It is closely related to ambient temperature. The lower the temperature in winter, the higher the cold idle speed. At a water temperature of about 0 degrees, it's approximately 1500 RPM. In summer, with a cold water temperature of 20 degrees, the idle speed is around 1000 RPM. The hot idle speed may vary slightly for each car system, mainly depending on the design.
From my over ten years of driving experience, the speed at 2000 RPM is not fixed—it depends on the current gear and the car model. For example, when driving an automatic car in the city, if you're in a low gear like first or second, the speed might only be around 20 to 40 km/h. But on the highway in a higher gear like fifth or overdrive, the speed could reach 80 to 100 km/h or more. Road conditions also matter—speed may drop slightly uphill and increase slightly downhill. My advice is to pay attention to the match between the tachometer and speedometer rather than guessing speed solely based on RPM. Observing more while driving is safer and more reliable, helping avoid speeding or fuel waste.
