straight extraurban road
indicated speed around 70 km/h
HSI indicator on the exact half of the ECO zone
After an acceleration phase, with RPM over 1500, revs settle down a little over 1000.
SOC is slightly growing, speed is constant in the ending.
The road is slightly downhill, but only 5 meters over 1 km.
Let's substitute elevation with accelerator pedal position:
After the initial pressure, pedal was settled down on a steady position.
Maybe it's the electric motor that is helping the petrol engine keeping its revs down?
Let's see the electric aid chart:
Current is flowing only in the initial acceleration phase, not during the following run.
Here's the engine load:
It doesn't change significantly over the sweet spot.
We can also see that the sweet spot happens during the heretical car state.
Let's add fuel flow to the chart:
The flow has values comparable to the S1 phase.
