How insane is a 140mph+ speedometer?

[Lazy2.5]

His question was the subject of the thread.

Right, it was just so subjective. I suppose the best I could do, is simply to respond with something equally subjective.

It would be... Pretty insane.

Has OP tried the A/T tires?

The speed cutoff on my stock manual 5 speed 4 cylinder Mazda 6 2004 was at 125mph. The CX-5 would probably be able to reach around the same speeds. It just won’t get there very fast. But I suspect the max speed on the speedos is selected more in terms of design and visual than actual speed expectations.

Remember the CX-5 is also sold in germany where autobahn don’t have speed limits. I don’t think a 140m’h speedo is crazy, but yes the car won’t make all the way there. Even if it could you would probably hit a speed limiter before that.

You can see in this video that he did about 212km/h (131mph) with his CX-5.

These cars need a ZF 8.

I would have been ok if my speedo stops at 90. 60-80 right at the top, and nothing after 90. Give me engine temp or oil pressure in that space.

The ZF8HP is for longitudinal configurations..

I am aware.

Theres a 9 speed ZF for transverse configs.

But Aisin also builds great transmissions, which is what Mazda would use.

The fastest I've been with my previous 2020 CX-5 was 105 mph. Briefly because I remembered that my last ticket was back in 2012.

I've done 110 in mine, but that was maybe 11-12 years ago now. And yeah same thing. I haven't had a ticket since 2010 or 2011.

I know there are some speedometers where the inaccuracy of the speed it indicates increases as the speed of the car goes up. My guess is a speedometer that has a pretty high upper speed measurement is done so the main part of where most people drive falls within acceptable accuracy tolerances.

That is a good point. Measuring devices of all types tend to be more accurate towards the center of their range.

We don't know that. Currently they engineer and produce their own, so they may well continue to do so.
