I would not touch a Kuga hybrid just to many problems, I get the feeling you have already made your mind up with the Mazda CX-60, the Outlander PHEV over 20,000 miles and 3 years excellent running cost at least a £1350.00, our previous Kuga Powershift 2.0 diesel would have cost nearly 3 times more.
PHEV technology over the past few years has advanced in leaps and bounds I have seen 4.6 miles/kWh and today 5 miles/kWh.
I think you should go for the CX-60 I would expect more than 45+ mpg average over the year.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
