BMW i4 boot space, seating & practicality
Boot space is very close to that of the petrol 4 Series, but rear-seat passengers might feel the squeeze
|Length||Width||Height||Boot volume (seats up/down)|
The i4 is neither frustratingly impractical nor vastly spacious. Its five-door coupe body makes it more versatile than a regular four-door saloon, but its rakish roofline means boot space isn’t comparable to what you get in one of BMW’s Touring estates.
BMW i4 interior space, storage & comfort
While boot space is only slightly affected by the i4’s batteries (see below) and there's a good amount of kneeroom for even taller passengers in the rear, the battery does eat into foot space for those in the back. Its presence creates quite a large central hump and a narrow middle seat in the rear, so the i4 isn’t great for carrying three passengers in the back. Two adults will sit happily there, though.
The i4 boasts a healthy 470 litres of boot space – which is only 10 down on the petrol-engined 4 Series Gran Coupe’s figure and more space than key rivals the Tesla Model 3 and Polestar 2. However, unlike the Polestar or Tesla, there's no frunk or under-bonnet storage in the i4: all you’ll find there is a large plastic panel covering a swathe of electrical components. The rear seats do fold down, though, creating a total capacity of 1,290 litres.
