Pretty much in the same boat as you with our X1 now over 3 years old. It’s a diesel and we’ll be doing more local driving so really wanted a PHEV but the AP is far too high for us. We did want the Outlander but there are none left so it’s been removed from the scheme.
I have been looking at the RAV4 hybrid in the design trim. I’ve also got a Lexus CT so know what driving a hybrid is like and how rubbish the infotainment is, but you can’t beat Toyota reliability. My main concern is mpg from a 2.5L engine even if it is a hybrid. The CT (1.8) does 40-45 locally depending on how you drive it! So I wouldn’t expect any more than 30-35mpg from the RAV4 in the real world.
