What the iX has over the i4
Based on the published spec sheets of the selected variants — a blank field on one side can also mean unlisted data.
The iX's wheelbase is 144 mm longer, which usually translates to more rear legroom. The iX is 118 mm wider — more shoulder room, but a tighter fit in parking bays. Boot space favours the iX: 500 litres against 470.
