Brake Specific Fuel Consumption

"Brake specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft, power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output.
Commonly BSFC is expressed in units of grams per kilowatt-hour (g/(kW·h))."- Wikipedia

Hybrid Assistant shows BSFC in the Engine Power Meter using a color scale reflecting efficiency:
Cyan - Best efficiency range (220 g/kWh)
Yellow - High efficiency range (230 g/kWh)
Orange - Medium efficiency range (240 g/kWh)
Red - Low efficiency range (> 240 g/kWh)

Actual thresholds vary with engine type, according to official Toyota documents

Engine Temperature Management

During the winter season, a classic trick is covering up the radiator grid, but this can be risky if you don't properly monitor the engine temperature.

You can use Hybrid Assistant, while driving, to check that the engine temperature stays within operating limits.
While this is usually not an issue in a urban environment, driving on the highway is not always considered safe.
Using Hybrid Reporter, you can check the engine behavior: here is a test of 20 kms at 130 km/h indicated speed.
The engine coolant temperature settles on a safe value of 90°C.
We can see that the electric engine temperature was raising, but its operating temperature is way higher that the petrol one, beeing able to work until about 160°C.
A higher trip may show if the trend will slow down and settle on a stable temperature.

Aggregated Trip Reports

It's now possible to aggregate trips is a single report in Hybrid Reporter.
Trips must be contiguous.
If you want to aggregate 3 trips, select the first trip in the trips list and press Generate Report

Then select "3" as number of aggregated trips

Not all charts are available in aggregation mode, but those based on aggregate data will have a greater precision


Engine Stage Assistant

If you are driving a 3rd generation HSD car, like Auris, Yaris, or Prius 3, you can take advantage of the Engine Stage Assistant.
On screen indicators will help you perform a better S1 and to correctly switch to S4
