This is the Toyota Prius plug-in hybrid. In this range test, I want to discover the range on the highway in real driving conditions to find out the minimum range of this car. I also wanted to know how long it takes to fully charge the battery and how much the car consumes when the battery is completely dead.
This is the Toyota Prius plug-in hybrid with the 13.6 kWh kWh battery. It has a WLTP driving range of up to 72 km*. The Prius PHEV has a system output of 223 horsepower. This is provided by a newly developed 2.0-liter engine (152 DIN hp / 112 kW) and is used in combination with a new and more powerful transaxle front engine (163 DIN hp / 120 kW). The Prius goes from 0 to 100 km/h in 6.8 seconds. Torque is 190 Nm. The car is equipped with 2WD.

I will test the range at higher average speeds on the highway. I want to know what the minimum range of this car could be. I did the test in May and it was around 16 degrees at the time of the test.
At the beginning of this part of the test, the battery is fully charged to 100%. The range indicator shows a range of 67 km. As a reference point to determine the distance of the driving range, I use the total mileage: 14,006 km.
During this ride we drove at a constant speed of 110 to 120 km/h. After driving 20 km, the driving range indicator shows 45 km remaining driving range and the average consumption is 18.5 kWh/100 km. After driving 37 km, the driving range indicator shows 23 km remaining driving range and we are at an average consumption of 19.6 kWh/100 km.
We drive the battery all the way down and came up with a total driving range of 54 km on the highway (14,060 km – 14,006 km). I also do want to note that the battery does not appear to be completely dead. With the battery charge indicator, a blue bar remains visible when the battery is apparently empty, indicating the remaining charge.
As an average consumption, we recorded 19.9 kWh/100 km at the end of the trip. 
Toyota says that with the built-in 3.3 kW charger , you can charge the battery from 0 to 100% in four hours, with standard 220V mains power. We fully charged the car 2 times and the car indicated it would take 4h20 min to fully charge the battery.
After charging, we note that we have charged for a volume of 11.15 kWh. At the second session, the app indicated that we charged 11.44 kWh.
Based on that info, I assume that the usable capacity of the battery is around 11 to 11.4 kWh.
To determine fuel consumption with an empty battery, we conducted a test during the return trip from the Ardennes to Brussels, driving exclusively on the freeway. The total distance was 118 km. During this test drive, we consumed 5 liters of fuel per 100 km.
In conclusion, the effective driving range of the Toyota Prius Plug-in hybrid on the highway is 54 km and this measured in rather mild temperatures of around 16 degrees. In the city you will probably get a little more range You can charge the battery from 0 to 100% in 4h20 minutes. Wondering how much the consumption is with a dead battery? Based on our test drive, we came out at 5l/100 km on the highway.
