On my 02 Insight I could coast down to 16 MPH and still get 150 MPG with the engine idling. It had an instant FE bar graph on the dash and it would read max at 150 MPG down to 16 MPH coasting in neutral with engine on.

It worked out to .11 GPH idling, while coasting, with no accessory loads including radio.
You needed to rev match the re-engagement of the transmission in the Insight.

On the 08 Altima, also with the CVT, you could coast down to 16 MPH while still maxing out the bar graph instant MPG reading at 60 MPG, which was as high as it could read.
On some of my local back roads with 35 MPH speeds I could get very close to 60 MPG average in the Altima using pulse and coast (engine on).

In the Insight it was close to 90 MPG on the same route.

I never coasted engine off in either vehicle but when coasting engine on, I divided the coasting speed by 16 and the mulitplied it by 60 (Altima) and 150 Insight to get my higher speed coasting MPG. Used wisely it could make a significant difference in overall MPG.
