Why not take advantage of the chance to hear the gasoline engine roar while we still have internal combustion engines and the shift to all-electric hasn’t happened? However, there are a few reasons you may wish to rev the engine or even need to rev your car if you have car problems.
Some people do it for fun as they like the roar from the tailpipe, or it is common practice when you are changing gear, and the engine revs and clutch need to be at the desired speed for the stick shift to slot into gear. We will often look at here: why and how do you rev a car to resolve an issue?
In our guide, no matter if you have a manual or automatic transmission, you can see how to rev engine while driving. By the end, you’ll know enough about how to rev a car to make a loud noise in front of your friends and how to ensure you have enough power by feathering the accelerator pedal if your engine occasionally splutters and you think it’s about to die.

What Does Revving An Engine Mean?
Revving is pressing the accelerator while the car is in park or neutral to increase the engine’s RPM. The main reason people rev their engines is to show off the throaty roar of an exhaust. However, in acceleration as soon as possible, drag racers rev their engines just before the race begins.
The main goal of revving is to increase oil flow through the car and the engine revolutions. If the engine was idle, the oil starvation and low revs mean the car would start slower. The tachymeter on the dashboard displays your current number of revolutions as you accelerate.
In addition, when you rev your car engine can help boost power going into a battery, particularly if you have charging problems.
When it’s cold outside, revving the engine may heat your engine to the correct operating temperature and help warm the cabin. This is true in icy regions where the chilly temperatures could cause the engine to stall.
You may wonder, in doing this, is it reasonable to rev your car? It is okay to rev your car occasionally for the reasons mentioned earlier, yet you wouldn’t want to redline as this pushes the engine to the top end of the revs it can do and could cause damage.
Most vehicles feature a rev limiter, which limits the maximum speed set by the manufacturers. Even with all this, how to rev a car while driving is different, as is how to rev the engine in a manual or automatic car.
How To Rev An Automatic Car That is Stationary
There are a few ways to approach if you want to rev your car and have an automatic transmission. The best way to rev an automatic car is to put it in neutral (N) and press the gas pedal while simultaneously pressing down the brake pedal.
People often focus on the rev counter or have their minds somewhere else, not noticing that the car is slowly moving as it is in neutral. Therefore, make it a habit to keep the brake pedal down when revving or keep the emergency brake engaged as you rev the vehicle. Then, after you rev your parked car, release the brakes, and you can continue.
It is also possible to rev the car in park (P); the procedure is the same as when the vehicle is neutral. Some cars with paddle shifters allow you to switch to neutral by pressing down both paddles simultaneously, which can come in handy as everything is by your fingertips.
An important thing to remember is to let the engine’s RPM go back to normal before putting the car into first gear or driving. If you don’t, you risk damaging the transmission, which is not cheap. (Read Anti Rattle Where Do The Clips Go On Brake Pads Guide)
How To Rev Manual Transmission Vehicle Without It Moving
It’s simpler and more usual to rev a manual car, and the clutch pedal, the third pedal, is to blame. Even driving at 85 mph on a highway, the clutch allows you to rev a car with manual transmission. You push the clutch for the engine to go into neutral mode as it disengages the clutch plates. However, revving the engine while coasting in neutral is not recommended as you lose control of your vehicle.
You can rev your engine when stationary by simply being in any gear, fully depressing the clutch, or applying varying amounts of pressure to the gas pedal. You’ll rev the engine without engaging the clutch by pressing the manual transmission gearshift into neutral and pressing the gas pedal. You can also engage the emergency brake in both situations to stop the car from moving.
It is better not to let go of the clutch when in gear before the RPMs drop to idle, even if it won’t do as much damage as with an automatic. This is comparable to putting the car in “D” when it is already revved.
Advanced Manual Revving
In a manual car, revving the engine is simple, but there are some situations when revving the engine is a little trickier, such as rev-matching. Rev matching is downshifting the car while maintaining a high RPM to match the engine and transmission speed. For instance, you would want to downshift to stay in a certain powerband while slowing on a racetrack. Thanks to this method, you could accelerate again with much power.
In a typical use scenario, you could tow or drive uphill and need a lower gear. You would rev-match your car engine to maintain your current speed yet in a lower gear. Rev-matching allows the engine to match the RPMs of the new gear, reducing driveline stress and preventing extreme weight transfer when towing. To rev a car, you depress the clutch pedal and shift into a lower gear while blipping the throttle and releasing the clutch pedal to drive normally.
How You Shouldn’t Rev Engine
Now that you know how to rev an automatic and manual car, avoid these mistakes. While revving will pressurize the fluids and make the engine oil circulate faster, you should never rev a cold engine.
Only rev a hot, full-temperature engine. If you don’t, you risk harming engine components since cold oil can’t lubricate. If you’re going to rev, ensure the oil and engine are hot. This can vary depending on the weather. Drive at least 30 minutes before revving your car engine too much. (Learn How To Use Brake Cleaner Without Removing Tire)
Is it wrong to rev the engine while driving?
The answer depends on your vehicle’s make, model, and driving behavior. Revving the engine while driving might cause speeding and accidents. Suppose you’re wondering if it’s safe to rev the engine while driving, don’t.
How do you rev an automatic car engine while driving?
An automatic engine can be revved in a few ways while moving. One is to shift gears using the shift lever, increasing the engine to higher revs. Another is to increase the engine’s RPM and press the cars accelerator pedal.
Is driving 80 bad for your car?
Generally speaking, driving 80 mph is not bad for your car; it is the definitive answer. However, driving at this speed comes with some dangers, including the possibility of collisions.
It can be a better idea to drive slower if you’re concerned about your car’s safety and want to avoid any potential issues.
Is it better to rev in park or neutral?
Generally speaking, revving while in park is preferable since it increases tire spin and power production. Although neutral is technically the greatest gear, finding the right gear in neutral can be challenging, and you might not get as much power from the engine.
Is it safe to rev engines in neutral?
The make and model of your car, your driving style, and the engine’s health can all affect this, so there is no definitive answer. However, due to potential damage, many experts advise avoiding revving an engine while it is neutral. (Read My Brake Pedal Is Stiff And Car Won’t Start)
Does revving warm engine?
Revving the engine can help it warm although a car engine will function best when running at a constant speed, revving will only increase its speed for a short period before they cool down again.
Is It Bad To Rev Your Car Engine?
Considering its many advantages, such as increasing lubricant circulation and warming the cabin, occasionally revving your engine is not bad. Nevertheless, redlining, or reaching the tachometer’s red line, is not advised when revving. It might damage a car’s engine.
How To Rev My Engine While Driving?
In automatic cars, you can rev your engine when you press the brake and switch to neutral while driving. As the needle on the tachometer gauge rises to a greater limit, gradually step on the accelerator.
Rev matching is the speed of synchronizing the vehicle engine and transmission speeds with manual cars to match a seamless shift into the desired gear. Finally, you press the clutch and step on the gas pedal to start the car. (Learn How To Clean An Aluminum Intake Manifold)
Do You Rev The Engine In Park Or Neutral?
When revving an automatic vehicle, put it in park mode.
Is Hitting The Rev Limiter Bad?
The red line shows you are revving too much, and the engine speed is at the top of what they designed it for. When you hit the rev limiter, you go past any acceptable rev limit and can cause engine damage.
