Toyota RAV4 Plug-In Hybrid Prime: 100 km distance with fuel consumption (economy) test, charged PHEV

Toyota RAV4 Plug-In Hybrid (Prime) is a Plug-In Hybrid car with 1.0 - 1.2 l/100 km WLTP fuel consumption (235-196 mpg US | 283-235 mpg UK fuel economy). Is that true? I checked it on 100 km (a little bit over) trip starting with fully charged batteries (similar to WLTP homologation procedure). The result: 0.4 l/100 km (588 mpg US | 706 mpg UK) fuel consumption and 13.2 kWh/100 km (212 Wh/100 mi | 4.71 mpkWh) power consumption (economy).

As always, I checked real fuel consumption on a petrol station. I noticed 1% difference: computer shows lower by ~1% fuel consumption comparing to what I refueled.
