Trip summary values are detailed by Time, Moving and EV.
Time is the total trip time.
Moving stats regards only the fraction of time while the car was not standing still.
EV stats are accounted only when the petrol engine is stopped.
No Fuel sums EV driving with the petrol engine running without fuel like coasting at high speed or driving down a slope.

Plot of power required to keep a given speed.
Values are collected only when a constant speed is maintained long enough to have a consistent reading, so a trip with many different speeds may not gather enough data to plot.
Since required energy is heavily influenced by road slope, you should drive on a plain road to have a correct reading.

Charge and discharge kW limits for the battery.
These values may change with battery level and temperature.
When the battery is nearly full, charge limit is reduced.
On low temperatures, charge and discharge limits are reduced to preserve battery life.

The average BSFC value is plotted with a colored dot.
Range of BSFC excursion is plotted with a green line, so the shorter the line is, the more precise the BSFC value.

  • Pulse: accelerating with nearly all ICE power given to traction.
  • Approximate Glide: cruising with no electrical or mechanical traction (approximate evaluation).
  • Coasting: cruising with no accelerator or brake applied.
  • Heretical: cruising with MG1 electric motor providing traction.
  • Accelerator pressed: accerator pedal is pressed, even if not actually accelerating.
  • Accelerating: car speed is increasing.
  • Moving: car is not stopped.
