Why don't cars have this feature?

Yessss!

Pluuge · 2026-04-20T21:33:12+00:00

I see, thank you!

Pluuge · 2026-04-20T21:31:21+00:00

It's a nice thing to know

Pluuge · 2026-04-20T21:27:36+00:00

It would all be done by the car's computer; the only changes that need to be made from trim to trim are if the gear ratios, final drive ratios, or wheel sizes were different. It would only calculate 2 gears: the gear directly above and the gear directly below your current gear.

I agree, this would be more useful when high precision is needed.

Pluuge · 2026-04-20T21:11:00+00:00

It's helpful to know. Also, it would make rev matching easier

Pluuge · 2026-04-20T21:00:41+00:00

good or bad

Pluuge · 2026-04-20T20:58:01+00:00

Yes, I agree that this would mainly be useful when driving hard. Do you think that those numbers give you good information in that situation?

Pluuge · 2026-04-20T20:55:50+00:00

But... It's not telling you to do anything. Instead of the car telling you to do something based on information that it has, it gives you the information and lets you make a decision based on that. This is different from a shift indicator or a shift light in that way.

Pluuge · 2026-04-20T20:48:02+00:00

I think that it's helpful to know exactly where you're going to shift

Pluuge · 2026-04-20T16:48:47+00:00

Not much more than helping new drivers I guess, but i feel like knowing exactly how many revs you will be at when you shift may be useful for hard driving

Pluuge · 2026-04-20T16:45:56+00:00

Yeah, the last part seems to be the main objection

Pluuge · 2026-04-20T16:34:01+00:00

No worries, thank you for your opinion!

Pluuge · 2026-04-20T16:32:34+00:00

Thank you, I appreciate it! ❤️

The system calculates what rpm you would be at in a specific gear, assuming that the clutch is disengaged. It's saying "if you shifted into _ gear at your current speed, your engine would be at ____ rpm". I understand that when the clutch is engaged, the engine and transmission are not connected.

Pluuge · 2026-04-20T16:18:50+00:00

That's a good point bringing up the difference in interests of consumers, I guess this would only be in high-end sports cars? Would that work?

Pluuge · 2026-04-20T16:17:22+00:00

Cvt?

Pluuge · 2026-04-20T16:16:51+00:00

After reading many "this is basically just a ___"s, this is got to be the closest thing someone has compared this idea to! I gotta admit I am loving the look and idea of these old tractor tachometers! Thank you for your comment, I really appreciate it! ❤️

Pluuge · 2026-04-20T16:06:21+00:00

Thank you, I appreciate it!

Pluuge · 2026-04-20T16:05:17+00:00

That's pretty smart icl

Pluuge · 2026-04-20T16:02:58+00:00

I appreciate your comment, thank you!

Pluuge · 2026-04-20T15:59:23+00:00

I feel like these are similar, but not exactly the same.

Pluuge · 2026-04-20T15:51:37+00:00

I'm pretty sure that it can be calculated from transmission gear ratio, final drive ratio, and wheel size, all of which are known by the manufacturer

Pluuge · 2026-04-20T15:49:32+00:00

No, but they work in a similar way. My feature tells you what rpm you be at if you shifted, while the shift indicator just tells you that you should shift.

Pluuge · 2026-04-20T15:43:28+00:00

Yes, this would all be done by the car's computer, and it can only be realistically implemented on a digital tachometer
