Car Tachometer Explained-What Do The RPM Numbers Mean

In this video, I tell you everything that there is to know about the tachometer on a car. You will find a tachometer on the dashboard of most cars, and it serves a big purpose with regards to telling you what is going on with the car while you are driving. The most interesting thing about it is that many people don't actually know how to read a car tachometer and don't fully understand what it means. I made this video to clear that up and educate drivers about their car's tachometer.

I didn't know Jack septiceye did DIY car videos

[tylervu]

That makes so much more sense thx I’m trying to learn more abt cars because I can drive now

I didn’t know Jordan Peterson did DIY car videos.

Wow, I have always been interested in what a tachometer really was for in vehicles, and I knew that it was for rpm. I knew what the red was for too, and the x1, 000r was for also. Basically, I like numbers. I always appreciate when someone describes in everything in detail about vehicles and how they work because seriously, there might be someone that is curious about how a part of a vehicle works.

This helped a lot because I was trying to figure out why my car goes 4 rpm when I accelerate sometimes.

[trentclark]

Wow! I still didn't know what an actual rpm is? Is it a complete rotation of the drive shaft? Is it a rotation of each piston? Might wanna make the title of videos actually match the content (just an idea) I guess my search continues

Hello, I just want to know why red line in the tacometer, because, I’m worried about this red line to my car tachometer too?

[ryans]

It all depends on what gear the cars in at the certain speed your going that determines how fast the engine spins. Example if your doing highway speed well the transmission will be in its highest gear and that’s pretty much a direct link to the engine speed so you probably see an rpm of 2000 doing highway speed. In city driving probably using gear 3 mostly so the engine speed will probably stick around 1500 or less. Every car is different but you want a lower engine speed to save fuel.

Hello I saw an Audi 2.0TDI which is going up to 6000 rpm while another one 1.8TFSI is going up to 8000 rpm but I know that the TDI is faster and more powerful why do you think the less powerful have a higher rpm?

[raydecampos]

Incredible annoying! I shut off the vid in 12 seconds and went elsewhere

[mraravind]

Why is RPM called revolutions per minute and not rotations per minute? What is it revolving around?

[todaysupdate]

I drive VW Golf 5 1.4 patrol engine and 80 ps . My RPM goes over 3800 when I am at 120 km . Is it normal?
Thanks.

[charakaamayantha_ca]

Thank you very much. Really informative

[YouTooCanDo]

Is it good to run the car to the red line time to time ??

[joshuagautreau]

How is the red determined? Most cars specs show a horsepower and torque rating at different ratings and different rpm’s which are always below the redline. So does that mean you can get more horsepower and torque if you hit the redline? Sorry I’m confused

[ianrawlings]

Thanks for screaming at me in a stupid Muppet voice! Didn't answer the basic question: what part of the car is revolving that is being measured?

[anireseegam]

Omg your voice stopped me 1 minutes in

[kaybullock]

Man, I wanted to watch this video but I have the volume down to 14 and this guy's screaming is making it impossible.

[priscilleanak]

So for the car to run fast it depends on power or speed?

[vincentyap]

Speedometer vs Tachometer which is more accurate
