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

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.

Boot space

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 better than the luggage capacity of key rivals the Tesla Model 3 and Polestar 2 – which combine the numbers for their front and rear load areas. The i4 has no under-bonnet storage, however: 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.
