Prius Prime - 5.6 miles/kWh and 30 miles of EV

When you own a plug-in hybrid, range of electric-only driving is the focus. But after 5.5 years of owning 2, attention has shifted to EV efficiency. We will be replacing one of our Prius Prime with a bZ4X. That's why I created this video to draw attention to how electricity consumption is measured.

In this example, it is the same route in the same conditions I have been filming for years to document battery degradation. Turns out, after 5.5 years and 60,000 miles, the outcome is the same. It is still delivering a little over 30 miles. What that means in terms of EV efficiency is a result of 5.6 miles/kWh.

Watch the video to see detail of the drive. Note that this was 2 complete round trips of 15 miles each. Also note that the screen in the lower-left is an aftermarket app called "Hybrid Assistant" which shows information the dashboard display (lower-right) does not provide, such as true state-of-charge and kilowatt-draw.

 

This was my check from late August.
