Accuracy of Speedometers
Rd
only thing that bothers me is that the CR-V's speedometer seems to be
fast. It seems that when I drive the CR-V at 70 a lot more cars pass
me than when I drive the other car, a Vette, at 70. Also it feels
like it is going less than 70, seems the speedometer its 4 or 5 mph
fast.
Questions.
1. Are Honda's and in particular CR-V's speedometers fast, i.e. shows
a faster speed that the car is actually going?
2. Have Honda's had a problem with the accuracy of their speedometer?
3. Can the dealer check it. If the speedometer is fast the
discrepancy between actual speed and speedometer speed will increase
with speed. Don't want to have a "friendly" cop clock me at 70
If the speedometers are fast this could be a problem for people who
lease their cars, because of the surcharge on mileage over a certain
amount.
Thanks for the help.

I have a Honda Civic and a Acura Legend.
Both have speedometers that read about 10% fast, i.e 70 mph on speedometer = 63
mph actual. HOWEVER, THE ODOMETER IS ACCURATE.
You can check the speedometer out with the odometer or milage markers on the
highway. Drive at a set speed for one mile and measure the time to travel the
one mile. Divide 3600 by the time to travel the mile and that will give you
your speed.
Acura said they would replace the speedometer if it was more than 10% off -
mine was slightly less. Go to the dealer and ask them to check it out.
Good Luck, Rick

I've heard that they read high on purpose as a defense against some
asshole suing because he got a speeding ticked when the speedo showed
the wrong speed. I had my 92 Integra's speedo checked when it was nearly
new. (The auto club had a set of rollers that they put the car on and
compared actual v. indicated.) Mine read consistenly high and the
difference increased with speed. For example, true 29 read as 30 while
true 66 read as 70.

up to 70 indicated. The sign flipped between 64 and 65. In contrast, by
Saturn speedo is only 2-3mph fast. I think that all speedos read a
little fast to keep people from getting tickets.

Not necessarily. The speedometer and the odometer don't have to be
consistent.

having speedometers that read high. I cruise all the time
at 75-80mph indicated and I KNOW I'm not actually going
that fast. My summer tire/rim combo is also of a slightly
smaller circumferance than stock so this just makes the
situation worse. I plan on compensating for this with my
next set of tires, however.
I'll be going from a 185/60R14 to either 195/60R14 or
205/60R14. The larger of the two possibilities will
increase my speed at a given gear and RPM by about 4% which
will compensate for the optimistic speedometer a touch.
Yes, you can also figure out your speedometer using the
mile markers and a stopwatch. Just start it when passing a
marker and cruise at a steady 60mph. Hit 'stop' when
passing the next mile marker. This will give you a good
idea how accurate your speedometer is. Did it take you 64
seconds to reach that 2nd marker? then divide 64 by 60
which equals 1.066 so your speedometer is off by about 6-7%.

depending on true speed. I drive a 95 'teg with stock tires.

This was discussed at some length in a Del Sol mail list, and as far
as I can tell, Honda has *never* made a car with an accurate
speedometer.
I have no idea why. Your dealer will likely tell you that the speedo
is
within the Federal specs of +- 10 mph, which it likely is. I
personally
find it most difficult to imagine that a company with the resources of
Honda can't build a car with a more accurate speedo. My little S model
read 5-10 over (depending on specific speed) which I thought was due to
it having small wheels/tires. My VTEC model has the same problem with
1" larger wheels/tires. It's a stupid Honda thing I think.

More likely it's an anti-litigation adjustment.

I had a GPS receiver running during a holiday trip to Georgia (in a '97
Civic EX, FWIW) and noticed that the speedometer consistently read about
5% high whenever the GPS had good track; 70 on the dash yielded about 66
- 67 MPH over the ground.

control was set at an indicated 81 MPH. The ticket said 75 MPH. I didn't
argue. :-)
But ever since, I've mentally subtracted 5 MPH from the speed my Accord
says it's going. (Yes, you policemen out there: the ticket I received has
let to me driving FASTER!)
