Why not have this gauge standard in every car? I doubt it is very expensive to add. I used to have a porsche 944 that had a fuel economy gauge and you could definitely tell how to drive with more efficiency.


Nissan plans on adding an instant fuel economy reader to every new Nissan and Infiniti it sells by 2010, and the meter is already available Stateside in the Altima and G35. The gauge is being added to show drivers how to drive with reduced fuel consumption in mind, and Nissan thinks owners can achieve 10% better fuel economy after using the gauge to adjust driving habits.

As an owner of a Volvo S40 with the same feature, I can personally tell you it works. My fuel economy went from 24.5 MPG to 27 MPG within a couple weeks of discovering the feature, and all it took was more coasting before stop lights, and less heavy acceleration from a stop

Easy, accelerating with a light foot will give you better fuel economy. There's a "drive it hard" school of thought, but that has nothing to do with fuel economy.

A boost or vacuum gauge would also work as a fuel economy gauge. The porsche 944 gauge was probably a vacuum gauge calibrated to show fuel economy.

Adding a gauge would cost $x. Now how many more warranty claims does it produce? Then people would complain how it isn't accurate. A lot of GM cars or cars with trip computers have this built in anyways. I think they were talking about a dedicated gauge.
