Rev meter

[Youth92]

Hi guys, I realised that there are cars out there without rev meters. Can I know why this is so? I asked one of my friends and he said that the car might not be a performance car. Then I was like thinking to myself, "taxi also not performance car what but they also have rev meter?" Honestly to me, it wouldn't be as nice if I were to drive a car without rev meter.

 

Share your thoughts friend..

 

 

 

 

Thanks!

One example is Axio. Sorry forgot to include. Heh!

The CVT transmission is designed to make the engine operate within a narrow band of rpm which is deemed to be optimum (thats where torque is ample) even as the gears are being shifted up. As such, a tachometer is practically useless.

Ohh. But there are cars with CVT transmission which comes with rev meters (eg. colt plus) and there are those without (eg. axio). Means the one in the colt plus is redundant?

 

Thanks anyway bro! appreciate it..

the designer forgotten to add RPM meter.. =x

interesting to reckon that Toyota Axio doesn't come with RPM meter.

it is common in Australia to see NO rev meter in entry lvl car, as it cost cheaper without one. thus think Toyota cut cost in Singapore too

Tachometer meter is never useless especially if you wanna prolong the life of the engine.

 

One of the example is that it is a good practice not to rev above 2k to 2.5k rpm while engine hasn't been warm-up.

Early Hyundais (from the 90s) dun have it too. As are some lower trim levels of the previous Lancer.

 

Save cost I think.

The Suzuki Swift 1.2L also doesn't have a rev meter..guess its due to cost cutting measures...

[Friendstar]

just how much can they save without a rev meter?

 

i wonder...

Actually I find it quite odd actually, cos they have to redesign the instrument panel to remove the meter and hence spend more money.

 

Weird.

Weird.

 

Redesign is a once off cost and this most probably being an inhouse effort anyway, will be a paper cost. Everytime a car is churned off the assembly line, Toyota saves the assembly cost(s), labour cost(s) and material cost(s) and this savings will grow for as many cars Toyota produce. You spend some money to save a lot of money in the long run. Makes sense to me.

Like i mentioned, the central idea behind CVT is to ensure that the engine rpm stays in the peak torque region by continously varying the (artificial) gear ratio. On paper, the rpm should not change even if the gears are changed.

 

Compared to cars with conventional torque converters which experience a surge of power which makes the car jerk/lurch forward, the CVT transfers the power to the wheel in a more refined and practical manner ensuring better efficiency.

Maybe a couple of dollars? It tends to add up though when you start building cars by the thousands..

Auto cars dont really need e rev meter as much as a manual car cos e autobox wil change gears at e correct revs.

 

Driver just monitor e speedo can already.

 

But its nice to hv n also makes e car look sporty.

 

But now auto hv manual shift mode so e rev meter comes in again.

 

Some pple prefer a large speedo so less confusing n display looks neater.

Most drivers dont look at rev meter. Ty only need to monitor speedo so as not to exceed speed limit.

On an auto, u can say its nice to hv but not necessary.

 

Early cars never hv. Then it was put in sporty cars n so everybody wanted it cos it looked ''sporty''.

 

Now in autos, its redundant but some like it as it makes a normal saloon a ''sports' car.

 

But fr normal driving, a big speedo is more useful cos easier to see yr speed n no chance of mixing up e speedo n rev meter.

 

Now many cars come with a bigger speedo n a smaller rev meter Maybe e time is coming when we wil see e rev meter disappear again. Design has gone full circle. Then in abt 20 years, e rev meter wil come back again.

 

Just like clothes. Fashion goes round n round cos ty hv run out of new ideas.

I do i am a weird driver as i look at it all the time. For one thing, i like to monitor the rubber band effect and secondly it is a good practice to prevent me from acquiring the "tah tua yew" syndrome.

My 1989 hyundai excel had it.

 

Even my 1979 datsun 100A had it. But my 1976 100A fII did not hv it so it was nice to hv on e 1979 model. Made e car more 'classy' if u can consider that car as classy.

 

Now its so common, no more improves e image of e car. In fact some high end luxury cars dont hv so its now opposite.

 

More classy not to hv it.
