I wrote down the specs. on the size delta between the 4 & the 6: [ EV4= 110.2" wheelbase / 178.7" length / 70.9" width / 66.9" height] [EV6= 114.1" wheelbase / 184.8" length / 74.4"width / 61" height"]
So it looks like the EV4 will only be a bit smaller. It appears that the battery construction is the biggest difference. I like the bigger height on the 4.
