Electronic Speedometer...

My moms Benzo has one. I think its actually all the functions that it has. Like for the Enzo i think you could check your top speed and all that. Not sure though....

 

no speedometer cable, it's electronic One thing I have noticed on my Vette is the speedo on the heads up display lags slightly under heavy braking.

 

The S2000 is one car that springs to mind.
There is no real difference between the two methods, just one is displayed in Digital figures.
I think that the information about speed that gets sent to the ECU is electronic anyways. Hence the speed limiter on many cars that have Analog Speedometers....
Just depends on what the desginers wanted to acheive with the car.

 

Mike.... you yabbie...

 

I don't think that is what he is referring to. You're talking about a digital speedometer DISPLAY. He is referring to an electronic SENSOR.

I know mechanical speedo's [typically] run off the transmission. I would guess that an electronic one calculates speed using wheel speed sensors (the same ones that are used for traction control).

 

Armen, be careful or i will tea-bag in your back yard!

Okay, i only read the post real quick, so sorry about my irelevant reply.

Okay, i think that there is a electronic sensor that runs out of the gearbox to correctly monitor the speed. It can be unreliable due to flucuation with the wheel size.
Maybe the Enzo uses GPS as a speed reference? Its not that uncommon.

Sorry about the Bad Grammer, dont feel too good today. Max came around last night.....

 

Digital vs Standard.

1) Digital is easier to read in a high speed situation, rather than looking at the dials.

2) Digital may not be more "accurate" but it does give the driver a more specific rate of speed. Meaning you'll know you're going "52 MPH". Instead of fiddling the needle between 50-55MPH trying to get the speed. It's just an example.

3) F1 uses Digital readouts, so it brings the car more toward F1.

4) More information can be stored on a digital display than a Standard Display, therefore giving the driver more invovlement with the car.

5) If the Digital Display is correct, then the Enzo can at least reach 226.92 MPH or 366km/h.

Here is a Enzo's display after it's been driven for quite a while.

lol gumball.

 

Yeah, bunch of rich boys driving around at high speeds illegally through most countries. Although when they went through Africa, they did it legally as the King of Morocco allowed them to. That's why the yellow Enzo reached the speed it did. The roads were pretty much cleared out for them, save for a few cars here and there.

I follow it enough cause there are quite a few interesting exotics that participate.

Year 2002 had a Ferrari F50.
Year 2003 had a another Ferrari F50 and a Koenigsegg CC8S
Year 2004 had two Enzo's one yellow ( as you see ) and one red ( which was crashed ).

These were the exotics of the exotics. There were plently of Porsche 911 Turbo's, a couple GT2's, loads of Ferrari 360's and Lamborghini's each year.

 

i have the entire gumball video with the yellow enzo in it, pretty cool... a few 360 crashes, a brutal viper crash but no enzo crash on tape.... if anyone wants it, PM me...

 

While @ Brands Hatch recently in an F50, my racing driver mate told me to watch the electronic gear selector on dash; it was showing 4 but he was in in 5 as car couldn't cope with speed of his gear change ! On changing down to 4 from 5 to 3 it righted itself. Strange but true ....

 

Carbon,
yes, the gear number is displayed on the all electronic dash read out.

 

Not sure but i think the shift is mechanical. I 'll ask Peter, the driver !

 

Carbon I read somewhere that Ferrari wanted to put the F1 tranny in the F50 and that is why there is a display for the gear, but when they decided it would be a reg. trans they just rigged the display to show what gear the box was in.

Back in the old days, speedometers were connected to a take-off somewhere downstream of the transmission output shaft (typically inside the transmission case itself) by means of a mechanical cable, not unlike the flexible cable used between the drive motor and the working end of a Dremel tool. The shaft, spinning inside the cable jacket, drove a magnetic or (less often) centrifugal mechanism inside the speedometer assembly that displaced the gauge needle to indicate speed.

An electronic speedometer, on the other hand, counts the rate at which electric pulses are generated by a sender positioned where the old mechanical cable used to go. They started showing up everywhere about twenty-five years ago. If you get in a car made in the '70s or '80s and it has the word "Electronic" printed on the speedometer dial, it uses pulse-counter rather than a mechanical cable.

Nowadays, most speedometers are electronic, and the "Electronic" label has been dropped from most speedometer dials.

 

You are correct and teenferrarifan's explanation is as good as I've heard on how it got that way.
