For me it's consistently been Mitsubishi's .. any of them.
Rentals, work fleet cars, my mothers Lancer, my wifes Triton .. all of them have been way, way out. For example, my wifes Triton as best I can tell, you need to be doing at least 118km/h on the speedo to be anywhere near a real 110km/h road speed. All the Falcons / Commodores I'd driven (stock) have always been almost dead-on accurate for speed. Seems to be getting worse with newer vehicles. I'm assuming people see inconsistencies between speedo's and built-in GPS systems? |

If they are accurate then something is wrong. I am sure that federal government legislation is that all vehicles must read under the actual speed.
I set my Fg ute on 113 by speedo and GPS 110 south Australia

Yep, my wife's Mitsubishi ASX is way out when we take her car somewhere and I plug in my accurate Garmin GPS by a good 8Km/hr out at 100.
![]() Having said that my new 2017 Mustang is also a fair way out by at least 5km/hr under even at 60km/hr. The best was the FG MKII XR6T at only 1 - 2km/hr under. |

My first car was consistently out.
Speedo went up to 80mph but seemed to always read "ignition light mph". ![]()

Every ford I've ever owned has been out by a consistent 5kph. My wifes' BF wagon 115 = 110kph. The AU work hack is the same, 115@110kph. My Fairlane is a bit more because I run 235/45 tyres instead of the factory 225/50 series.

I agree with the OP. I have had the wife's 2008 Outlander & her current 2016 ASX, both were considerably out at 100km/h or 110km/h when compared to the GPS.
A couple of years ago, I was cruising my son's FG at 125km/h south of Taroom (Qld.) on the Leichardt Hwy. in the distance coming around the corner I could make out a motorcycle rider with a white helmet, Brain tells this is not correct braked straight away, it was a police motorcycle officer and he clocked me at 111 km/h, 1 point off my license (me thinks that will do ![]() Many many years ago, my first car was a 1974 LH torana, ![]() ![]() ![]() |

I only compared my GPS and speedo the other day actually . When my digital speed was showing spot on 100 the GPS was telling me 97-98 for my 2008 FG XR6 .. The AU is about 5 kays optimistic and the little Honda Accord I also have is about 6-7 out at 100 I reckon.
My dear old Dad had a Zephyr Mk2 when I was a kid and that speedo jumped around all over the place ., The speed we were travelling at was anyone's guess. All you knew was that you were at somewhere between 20-30 , 30-40 , 40-50 etc miles per hour . Last edited by roddy1960; 02-07-2018 at 07:59 PM. |

both Suzuki m/bikes run 10% over which is the max allowed by law (at indicated 100 I'm doing 90 because I'd never confirm that an indicated 110 is an actual 100

Mitsubishi is pretty bad. The work 2016 Pajeros were out by at least 8km/h at 110km/h.
But we just got new 2018 ones that are only out by 2 or 3 at 110km/h. Fixed the speedo's but everything else about them is still garbage for 2018 standards. |

My first car was a Morris 1100... the only time you could read a constant speed was 90Mph going flat out down hill (a very long and steep hill
![]() ![]() Other than that... it would constantly jump back and forth about 10 - 15Mph... so you just had to go on average speed (the average of the min/max shown by the needle at any given point ![]() D

We had a Grand Voyager. Speed was 100% correct with the GPS.
My 2009 Fiesta when set at just over 111kmph on the speedo , is 100kmh on GPS. 122 is 110 on GPS.

![]() Maybe your Torana had the wrong speedo gear drive put in the gearbox. I found that the worst speedos were XY Falcons when doing 90mph and over the needle would bounce up and down when you hit bumps on the road and the HK Holden you got the same type of crap. |

A mate had a VN commy. According to him the speedo was showing about 110 when he was Sitting side by side with me while I was driving a near new car showing a bit over 90. I GPS tested that car and it was only out by a couple of km at that speed. After realising this my mate said "no wonder everyone always overtakes me"
That car was a shot box so no wonder it was out by so much. |

Could have a speedo issue, but it did read near enough correct speed under 100km/h, I did get done by the police radar in a built up area, doing 70 in a 60 and that was about what the speedo was reading at the time. https://fordforums.com.au/showpost.p...6&postcount=31 Wheels magazine test back in 1977, was where I realized the toranas had a speedo issue in the higher speed regions, not just mine ![]() |

My 92 TR Magna is at most 2.5% out (i.e. it reads 2.5% faster than you're actually going).
My previous EB XR6 used to tell me I was going 120 when I was only going 105. |

The 03 Forrester and the 2012 Subaru Liberty that I drive occasionally both over read by 8-9 kph at 100 kph, my FGX only over reads by 1kph at 100, however the speedo in my XM is almost spot on which is amazing considering it has the wrong tyres, wrong wheels, wrong diff, wrong gearbox, and the wrong speedo.

My 2009 XR6 with new tyres at 100 reads 101 on gps. My wife's 2017 Camry at 100 reads 92 on gps. So the XR6 I have to be careful with!

No speedometer can be 100% accurate all the time. A typical tyre has 2-3% diameter through tread wear over its life. Manufacturers opt for reading high, as too close to the actual and they may be liable for fines received etc.
