They all have a stated battery so the ionic 5 is 84kwh but only 80kwh usable the Scenic is 92kwh with 87 kwh useable. On my test drive in the Ionic I got 4.1m/kw which would be 328miles and in the Scenic i got 3.4m/kw which is 295.8 miles. But since having the ionic my avg is 4.8 after nearly 200miles which is 384 miles but on some journeys usually a town driving it easily goes over an avg of 5.0 which is the 400mile mark which isn’t unheard of on the owners forums, I couldn’t find many people able to get more out of the scenic i think best i saw was 3.8m/kw which would give 330mile range but would be interesting to see how you get on, software updates can make a difference like it did with the skodas
