Towing a 1500kg caravan with the Outlander PHEV over a 200 mile journey achieve 28.5 mpg measure brim to brim the onboard screen shows high 29mpg, our Ford Kuga 2.0 diesel powershift achieved 29/30 on the display (I never carried out a brim to brim), petrol is slightly cheaper than diesel, so there is probably nothing in it.
Normal driving on pure petrol alone we are achieving around 37/38 mpg, the Kuga just over 40mpg, so not a lot in it.
If we did not tow a caravan we would definitely go for a full EV for us its a no brainer, the latest EV are now achieving 300 miles and 4.7 mile a kWh, on a good day a PHEV will achieve around 2.8 miles a kWh.
You half to accept a PHEV is really just a stop gap, EV have now taken over.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
