2023 Prius Prime - Share your MPGs!

"According to the North Carolina Consumers Council, drivers should expect to lose 1-2% of their fuel economy for every mile per hour they drive over 55mph."

 

I love the Vehicle/Trip Information/History screen for monitoring my MPGs. I can measure a single trip, parts of a trip, or all day. Just hit update to reset. And I get 199.99 measurability.

I like to keep it on the Current page when I drive though, so I can monitor the "instant MPG" bar on the right side of the screen. All I use that for is to see when the ICE cuts off. The Eco badge isn't always on when the ICE is off. When the bar pops up to 100 MPGs I can be certain the ICE is off. The Eco badge will come on a bit later.

How quiet must the new G5 Prius be if I can't hear when the ICE turns off???

One question: What would you estimate the length of your average drive to be (from start to shut-off)?

 

I see! I like to have the energy flow gauge up on the left side so I can see the reserve charge. If I've got 4 bars or higher, I know to let off the accelerator immediately at cruising speeds to cut the ICE. If I'm at 3 bars, I'll usually keep my foot steady longer to allow recharge and see if the ICE will cut off on its own.

If you have a lot of short trips (2 miles or less), you're going to get penalized in HV mode - particularly if you stop for a while. I think the G5 (in HV mode) might penalize drivers a bit more for short trips vs. the G4, simply due to the increased power output. When that larger displacement engine is on, it theoretically should be burning more fuel than its predecessor.

But if the drive is long enough, the bigger (more efficient?) battery in the HEV model exceeds the performance of the G4 in many ways. I can't name them exactly lol, but I'm consistently surprised by a very high MPG trip. I'll need the temps outside to drop to see if I can match my all-time highs in the G4 (adjusting for the prior gen's optimistic results).
