This seems weird…
Posted yesterday my new M240i. Here’s another picture. Anyway, on the drive home I’m following my wife in her GLC and thinking she’s gone crazy as I’m going 90 trying to keep up. I call and she says cruise control is at 81. We go back and forth and it seems the BMW is consistently 5-7 mph slow. So I text the dealership and this is the message I got back:
Hi Jason, glad you made it home safe! I asked service about your speedometer and learned that BMW speedometers are intentionally set to read roughly 3-8% higher than your actual speed to guarantee strict compliance with international legal safety margins. Because of that, a displayed speed of about 84-85 mph may equal a true GPS speed of around 80 mph. This only affects the speed shown on the dashboard and does not change the accuracy of the odometer.
Am I being bamboozled or is this a thing?
