Here you have the real-life CITY test of fuel consumption (fuel economy) in Volkswagen Arteon eHybrid Plug-In Hybrid (PHEV) 2022/2023: 1.4 l inline-4 turbo petrol + electric engine, FWD, DSG, in a city (also in heavy traffic, urban area) with almost empty batteries at start - in case you forgot to charge batteries before the city trip. Total system output: 160 kW (218 HP), 400 Nm, FWD. Result: 4.7 l/100 km (50.1 mpg US / 60.1 mpg UK).

VW Arteon eHybrid PHEV fuel and energy consumption (economy) in other scenarios (also on highway):    • Volkswagen Arteon eHybrid: fuel energ...  

If you start the city trip with fully charged batteries, you will achieve such fuel consumption/economy results:
30 mi distance: ∞ / ∞ mpg (US / UK)
50 km distance: 0.0 l/100 km
45 mi distance: 304 / 366 mpg (US / UK)
75 km distance: 0.9 l/100 km
60 mi distance: 135 / 162 mpg (US / UK)
100 km distance: 1.8 l/100 km
125 km distance: 2.4 l/100 km
75 mi distance: 101 / 121 mpg (US / UK)
150 km distance: 2.8 l/100 km
100 mi distance: 80.6 / 96.8 mpg (US / UK)
200 km distance: 3.3 l/100 km
125 mi distance: 71.9 / 86.3 mpg (US / UK)

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.
