After owning a 2004 Kluger CVX for 9 years I took delivery of my new 2013 Kluger KX-S last week (21/8/13). The 2004 model was always spot on in terms of speed accuracy (when checked against my various Garmin GPS' and those highway radar speed check displays one occasionally comes across). The new Kluger, however, shows a speed discrepancy of 4 Kl per hour .. i.e. 110kph on the speedo shows as 106kph on the Garmin. Even at lower speeds the discrepancy is the same .. 60kph on the speedo shows as 56 on the Garmin and so on. Its all very well to say this is within ADR tolerance rules and that there are benefits (e.g. avoidance of radar speed fines). It does not, however, necessarily make for safe and secure driving in certain situations. Only yesterday in an attempt to get up some kilometres prior to the first complimentary service check I took to driving down the Hume Highway from Sydney to Moss Vale for lunch and on three occasions at different times, despite driving in the slow lane at the speedo indicated speed of 110kph, different semis/B doubles/ triples etc came up behind and tailgated, flashed lights, air-horned me and eventually overtook cutting me off dangerously pulling sharply in front after overtaking. I was in the slow lane!! nowhere else to go. You just dont need it. Even though the Garmin was indicating a slower speed I did wonder if it was correct. Such doubts pass through the mind. Yes .. I will be complaining at the first service but if one takes notice of other contributors to this topic, probably to no avail.
