Tachometer Reading at Cruising Speed
« on: August 01, 2008, 09:39:48 AM »
My tachometer reading is as follows at cruising speed.

80km/h - 2000rpm
90km/h - 2200 rpm
100km/h - 2400rpm

Some forumers claimed that their tachometer reads 2000rpm at 100km/h.

What is your reading tachometer reading at the above speeds?

*Note : Each small mark, ie. " - "  above the 2000rpm mark represents 200rpm.

CVT and 4AT have different Tacho Reading so son't worry about it, your's will be common to that of the 4AT Gear Box

Yap, Jef is correct. For 4AT gearbox, the rpm is higher than CVT gearbox. That's why some forumers claimed that their tachometer reads 2000rpm at 100km/h is correct for CVT.

Hi,

I think the tachometer reading depends on the gradient of the road that you are driving and how fast you push the car to achieve that speed.

On a flat road, if i drive gently and let the speed increase, I can achieve 100 kmh at 2000 rpm.

You mean you managed to cruise on a flat road at at 100km/h at only 2000rpm on your Latio 4A/T?   :w00t:

How did you do that?  :confused1:

No matter how I tried, no matter how gently I stepped on my accelerator, my rpm still showed 2400rpm at 100km/h

the readings are right for the speeds you mentioned. For 4A/T only though. I add one more

at 120km/h, abt 2.8-2.9k rpm.

I noticed that at speeds above 80km/h for Latio 4A/T on overdrive, the tachometer increases 200rpm for every 10km/h gain in speed.

Guys, pls do not neglect your rim size and tire profile, all these affect the speed and revolution.  :smile:

I am driving Latio 4A/T on stock 185/65R15 tyres, and my rpm is as follows -

80km/h - 2000rpm
90km/h - 2200 rpm
100km/h - 2400rpm

Those of you driving Latio 4A/T whose cruising rpm differs from mine, did you upgrade your tyres and/or rims?

Didn't look at his mini info, but I'ld like to see his RPM at 100kmh if it's a 4AT.

Nope, I don't think there will be a difference in READING the speed on you meter dial when you up your tyre size, it's still based on your standard tyre size unless your car is so futuristic that speed is not measured using parameters preset in the ECU or based on your wheel rotation speed but an external source or you've re-calibrated your meter after changing wheels.

I'm using 205/55/16 and my rpm is still at 2400 when I'm travelling at 100kmh.
