What is the normal RPM for 60 mph?
While there is no exact number that will tell you what is considered normal RPM for a car, if your car revs between 2,000 and 3,000 RPM, you're considered to be within the average range.
What is the normal RPM range for cars? The normal RPM range for cars on highways is generally between 1500 rpm and 2000 rpm. The idle rotation ranges between 600 rpm and 1000 rpm.
Generally, the average car stays at about 2500 rpm while doing 70mph.
On most late model automobiles I have driven in the last 20 years, driving at 65 mph will result in the engine running between 2200 and 3000 rpm, depending on the automobile and engine type.
5,000 rpm is really high. 5000 rpm for 70 mph (112kph) is way to high for a normal passenger car or pick-up. Generally your average car does 2800 to 3000 rpm for 60 mph (100kpm) This equates to about 3100 to 3250 at 70mph.
A normal RPM when accelerating is between 2,000 and 2,500, unless you're putting the pedal to the metal. In this case, you may see higher RPMs. However, this isn't normal when you're just accelerating at a normal pace.
For most modern vehicle, you should not cruise above 2500 to 3000 rpm. Most of the turbo-charged engines develop a lot of more torque around 1800 to 2600 rpm range. Older engines, torque didn't peak until 3500+ rpm.
In most of today's cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won't feel smooth. The RPMs will jump up and down, for example, or they'll fall below 600 RPM (or whatever is typical for your vehicle).
That's also the speed at which most cars can already use the highest gear. This should be your guideline and not the number of RPM. But since you are asking - just cruising at a constant speed, I guess that about 1600–2000 RPM would be fine, depending on your car, engine type etc.
So at 80 MPH, the motor is turning 9,000 RPM. Manual transmission cars are the next easiest as there is typically no slippage in the drivetrain between the engine and the road.
What RPM is too low?
Actually below 1200 rpm in a high gear can quite possibly be harmful, not only in a turbo car. If you're cruising at one constant speed, or going downhill it is fine. However accelerating or going uphill at a low rpm and high gear is not good.
70mph = 2413rpm. how do you know your exact rpm?
Does a high RPM clean an engine? If your engine almost never runs at high rpm, then the valve seats could accumulate some deposits that might somewhat hurt their sealing ability. If you do some running at high rpm and load the higher valve seating velocity and temperature could help remove these deposits.
No. Engines are designed in such a way that they can perform at redline without breaking down or taking damage at those RPMs. This doesn't mean that you should redline your engine often. Working at peak performance be it an engine or anything else will take its toll and cause wear and tear.
In older vehicles, it was important to keep the rev's down so the engine would last a long time. But 3000 RPM in any engine built in recent years is no problem at all.
The higher the rpm, the more torque the engine is producing, and the more fuel it is using. Automatic transmissions take some of this control out of the driver's hands, but they, too, can be manipulated to maximize fuel efficiency.
Whenever possible, try to avoid hard or sudden acceleration to high speeds so that you prevent your engine from damage caused by over-revving. Step 4: Maintain fuel efficiency. For the best fuel efficiency, keep your RPMs between 1,500 and 2,000 RPM when driving at a constant speed.
High idle means a vehicle operating condition with engine disconnected from an external load (placed in either neutral or park) and operating at a speed of 2500 ±300 RPM.

Monitor RPMs when idle
If the needle is steady, this indicates your engine is running properly. If the needle drops by a few hundred or shoots above 1,000 RPM when the engine is warm, your engine may have a problem. You should have it checked by a professional.
What RPM should I shift at for speed?
Generally, you want to shift gears when your car reaches 2,500-3,000 RPM. Eventually, you will know when to shift by sound and feel.
Higher revolutions per minute equate to more fuel burnt in the same amount of time and more power produced. Because of this, most consider higher RPMs racing RPMs. Running at lower RPMs equates to higher torque and thus lower horsepower, while making higher RPM power outputs less torque and higher top horsepower.
Low RPMs are fine if you're just cruising or slowing down, but when you accelerate, low revs leave your engine with a gearing disadvantage. To get your car up to speed, the engine has to work a lot harder. Engine temperature will rise, and cylinder temperature will rise.
This may be a sign of a failing idle air control valve. The idle air control valve is located on or near your intake manifold that monitors the air intake as it is mixed with fuel prior to being injected into the engine.
That's also the speed at which most cars can already use the highest gear. This should be your guideline and not the number of RPM. But since you are asking - just cruising at a constant speed, I guess that about 1600–2000 RPM would be fine, depending on your car, engine type etc.
If you have a tachometer and a speedometer, you divide the rpm by the speed, so 50 miles per hour or 80 kilometers per hour at 2000 rpm would be 40 rpm per mile per hour or 25 rpm per kilometer per hour.
For most modern vehicle, you should not cruise above 2500 to 3000 rpm. Most of the turbo-charged engines develop a lot of more torque around 1800 to 2600 rpm range. Older engines, torque didn't peak until 3500+ rpm.
The shift RPMs will be higher if you are further down on the throttle on faster acceleration. Shifting between 2000 and 3000 is normal.
Shifting up at 2,000 rpm (1,500 rpm for diesel) gives the best mix of speed and economy.
You probably already know that low RPMs are best for fuel efficiency. But there's more to it than simply shifting early. You probably already understand the basic concept of driving a stick-shift car for maximum efficiency: Keep the RPM as low as possible. The faster you spin your engine, the more fuel it consumes.
How fast is 3000 RPM in mph?
so the motor must turn about 6800 revolutions to go one mile. Thus, at 6800 rpm one is going 1 mile per minute, or 60 mph, approximately. So, 3000 rpm would be about 26 mph.
About 300,000 MPH, give or take.
8000 rpm = 154,2 mph.
