My new Monaro is the first car I have had with an accurate speedo. According to my road angel (which I think is about right) it’s almost spot on. This compares very well to any other cars I have tried out the comparison on. My M5 for example showed over 10% fast at any sort of speed. It does mean that in 'camera' areas, when it says 50 I stick to 50 etc. What’s your experience?

On mine, the analogue one is naff. The digital one is better.

anyone else find that the bloody digital reads a few mph, quite a few, less than the analogue? Mind I am going to get the dials replaced as I;ve had the sticky speedo/rev counter so it could be that...

Calibrated mine over 1km against the 100m markers on the motorway with the cruise set at a certain speed... calculated figure from timing showed the speedo to be over-reading by 0.045%. How very inaccurate!

ETA: That's when it's not reading 200mph while I'm stationary of course...

Mine is pretty accurate compared to GPS, even at really high speeds (on a private road).

Stack was always my first choice for Motorsport, simply the best IMHO. Out of interest my 4 door HSVs both have very inaccurate speedos compared to Stack readouts
