Macan's Speedometer Error
in 95B (Macan, Macan S, Macan GTS, Macan Turbo, Macan S Diesel)
Posted
My 2015 Macan S is a bit closer at 4.2% fast. An cruise at 124 kph results in an actual GPS speed of 119 kph. The indicated fuel consumption was 9.8 L/100km - actual measured was 9.9 L/100km. So fuel consumption was reasonably accurate at 1% error probably the error inherent anyway in measuring by usage from full tank to full tank.
