I hve only sat in the XT E-4orce it was imo as roomy as the Kodiaq and the back seats slided to more luggage or passenger room. I was meant to go back and test drive the E-power but never got round to it.
The XT E-power would be more lively and on paper has better economy 48 -39 on the Kodiaq. Have a look on the XT thread there’s also a couple of video’s.
