Each BMW is always bigger than the last.
the 5 series is bigger than a 2 model old 7 series
The 3 series is bigger than a 2 model old 5 series.
the 1 series will soon be the same size is a 90′s 3 series.
The X3 is now as big as the old X5.
If the 1 series gets too big I wonder if they will introduce a 0 series?
They will, but it’ll be a supermini. However, though I do agree with you, the 1 Series is perhaps the one model that actually did need to be just a tad bigger so the cabin wasn’t so pokey.
The 1 series big packaging problem is that the bonnet is far too long for a car this size to have practical cabin space. Its designed to take a long straight 6 engine.
There is a reason that cars this size usually have compact east-west engines.
If they want to stay rear-wheel-drive, then they need to use only 4cyl engines (with turbos etc). They will then be able to design a shorter bonnet and allow the proportionally bigger cabin.
Why is it that the 1 series has so little head room that it struggles to accomodate anyone over 6 foot tall forcing them to bend their neck and stare at the floor while all 3 series are fine? Even the the 2002 from the 70s had far more head room while being externally smaller than the 1 series. Of late it seems BMW have become obsessed with quirky designs with angular concave surfaces but have forgotten that what made BMW great was devotion to purpose, making a car that was a pleasure to drive while comfortably accomodating people and whatever they wanted to transport.
