Generally speaking, when driving at high speed, maximum speed is 120 km/h. Of course, some people drive at 130 km/h because more than 10% is normal and is not considered speeding. Whether manual transmission or automatic transmission, drivers press accelerator pedal, and they generally do not go up and down. At this time, you can see speed of car's engine and check performance of car. Engines of different brands, sizes and models have different speeds at same speed. Currently, market is mainly 6-speed automatic transmissions, 7-speed clutches and 8-speed, and all manual transmissions are six-speed or five-speed. After increasing gear speed of transmission in a lower gear, when it is shifted to a higher gear, power consumption will be reduced, which saves fuel.
Engine speed is mainly determined by position of gearbox. At same speed, torque in lower gear is greater, and speed in higher gear is very high. After driving at high speed, gearbox is in top gear. Basically at 120 km/h, lower speed, better behavior of car. However, for sake of performance, many enterprises are now exaggerating and publishing information that engine speed of a tens of thousands of yuan brand car can reach more than 1,000 when driving at high speed, which is obviously a lie. The lower engine speed, better? Teacher: Don't be silly, it's best to count cars when you drive here.
When domestic motor runs at high speed, speed is mostly over 2000rpm. Generally speaking, speed of ordinary cars at high speed reaches 2000 - this is already good. Haval h6 is China's SUV sales record holder, and its performance has repeatedly broken new records. The 2.0t engine's high RPM is around 2300, which is already best domestic engine.
Summarizing, we can say that when driving a car at high speed, lower engine speed, better its performance. However, this requires actual data and it should be within a reasonable data range, more than 2000 is fine. Many sellers say 1000 rpm, so don't believe it. When motor speed is very low, it means that motor power is large and power is very stable. In addition to high performance vehicles, many small displacement vehicles have high engine speeds when driving at high speeds, making driver feel "powerless".
