    Speedometer is fast, 2nd Mirage with same problem

    I discovered Shelby, my '17 is also afflicted with a speedo that is optimistic according to 2 gpses I own.

    Zer0, my '14 was 5-6kmh fast mostly over the entire the range, dropping to about 3-4kmh fast @130+ kmh when compared to 3 gps units I own. Zer0 had alloys, Shelby has steel wheels. Both were 5mt.

    Has anyone else noticed this or have a speedo that's off?


    Zero, my 2014 ES Plus gone but not forgotten. We're driving the Beetle of the 21st century

    I have a habit of checking my speedo against the cop devices they setup at random that display your speed. (Not sure if you guys have that?) Mines dead on with factory diameter tires.

    Weird. I get the only 2 Mirages with fast speedos. I know where one of those cop speed things are, I'll use it this weekend if it's still there.

    Speck's speedometer also reports faster than actual speed.

    I have compared the driver's speedometer display with what the OBD-II reports. The OBD-II vehicle speed information is accurate when compared to the radar-based speed signs.

    It's not the only car I have driven that does this. I figure the factory setting is an error on the side of caution.

    Yep, places like the UK allow 10% + 2mph. Over that , even by 1 mph and you have a steep ticket. They have abundant speed cameras over there and plod loves to disguise themselves at the roadside and bag people.

    I had one driver say the speedo was out on a Mirage. It supposedly read too fast by 3-5kph. I never had a chance to confirm that but I don't doubt it. The speedo is out by around 5kph on my truck compared to my speedometer app on my phone. Our 5 ton is out by at least 3. Guess that's why cop cars have calibrated speedometers. At least all the police crown vics I've seen were.

    We have photo radar all over here too. They hide on top overpasses and get cars below, hide under underpasses in the median and get traffic going in the opposite direction out the back window.Soooo I'm a jerk and smoke them out whenever I have the chance if there's nobody else around. I don't support photo radar.
