Micra speedometer shows faster than it's really going

This has warranty and claimed mpg implications.

As for warranty mileage claims, definitely. My guess is that Nissan could divert those by establishing a "Grace" period that would account for those differences. That is assuming that a Micra would need work under warranty, which I consider unlikely; Micra's are well built machines with a long reputation for reliability. Still, I would argue the point.

As for MPG, Fuelly is still showing that I'm blowing away EPA estimates for highway driving (I'm driving mixed), and that's based on actual fill-ups and odometer readings at those fill-ups, so I doubt anyone would be able to make a claim with regards to that. I wonder if Nissan purposely set the economy estimates low in order to avoid litigation.

Yes, good point. I forgot how low the fuel economy numbers are on the new rating system.

I find it amusing: they are so low, and most people will applaud that we are finally getting ''real world'' ratings... and they would be absolutely right...not realizing, that the new numbers just indicate how most guys are asshats behind the wheel without a clue how badly they are driving. LOL.

EDIT:

Alpha... have you confirmed the odometer is also off?

I assume the odometer/speedo both get input from the same point, so they're both probably out the same amount.

When people spend less on transportation, they have money to spend other ways...

True, true.

I assume the odometer/speedo both get input from the same point, so they're both probably out the same amount.

But since the output to the odo/speedo comes from the ECU (no more direct mechanical drive speedo/odo cables), it would be easy to add a correction factor to one or the other. Just curious.

Ah, I didn't know they could be calibrated separately... anyway, I think they both need some tuning. (trucks are blowing by me and my commute is ''longer''! )
