I don't know what you mean by "cramped"... Yes, the rear floor is a bit higher than in an ordinary ICE or in my 330e, but the space is enough for an adult. The roof is leaning back, but unless your kids are huge, or expected to grow to over 2 m in height, I think the rear sitting space is plenty enough. Take them out for a ride in that i4 M50 and you will see that they will never again sit in a BMW M3. Anyway, my choice of buying the i4 was partially based on the shape of the car. I love REAL cars, not the touring or SUV types. My "kids" are 1.86 m and stopped growing and they have no issue sitting back there. Of course, the car may not be practical for long holiday trips with four adults if you bring a lot of luggage, but for more "normal" trips, I think it's more than enough.Oh I agree with most of the above. Overall the i4 is a brilliant EV and has proven to be in all reviews. I suppose I was thinking about the packaging, i.e. cabin space in the rear and the often mentioned transmission tunnel hump. Little insignificant details to most tbh but theyre the little details that are a constant callout in reviews.
I collected a new BMW M3 last October and my brother-in-law who works at my local dealership, keeps teasing me with the i4 M50 as an alternative. With 2 kids just hitting their teens, the M3, well the 3 series has acres of room in the rear for them and their friends which has been great. The i4 is just wee bit cramped, however I do know the i4 to be a top EV and I much, much, much prefer the quality both inside and out of the i4 when compared to a Tesla. Its a really nice place to sit.
