BMW i4 (2022-present): dimensions and boot space

All the dimensions you need to know for the new electric BMW i4, including width, length, height and boot size

The BMW i4 is an electric family car with up to 365 miles of driving range per charge. It joins BMW’s i range of electric models, and while it’s not as large as the BMW iX, it’s bigger than the previously-available BMW i3.

Here you can find out more about this BMW’s dimensions, boot space and weight. We’ll cover all versions here, including the eDrive40 and M50 versions. The former is the entry-level car, but it’s the one most people will choose because it has the most range and is significantly more affordable than the M50.

The M50 is the high-performance model and thanks to 544hp it’s able to race from 0-62mph in less than four seconds. It’s sportier to drive and has a bit less range than the eDrive40 model, too. In terms of dimensions, it’s virtually identical - as you’ll see below.

Alternatives to the BMW i4 include the Tesla Model 3 and Polestar 2, which we’ll use for comparisons. These models are also spacious family cars with enough space for family life. Read on to find out more about the BMW i4 and how big it is inside and out.


BMW i4 dimensions

The BMW i4 is 4,783mm long, which means it’s longer than both the Tesla Model 3 and Polestar 2, which are 4.7m and 4.6m long respectively.

With the mirrors folded in, the BMW i4 is 1,852mm across, and with them folded out it’s 2,073mm wide. It’s in between its rivals here, as the Tesla is a couple of millimetres narrower and the Polestar is a little wider.

The BMW i4 is 1,448mm tall, which again puts it in between these two alternatives. It’s much closer to the Tesla in size, as the differences in dimensions are pretty minimal. The eDrive40 and M50 models are identical in size.

BMW i4 boot space

Both versions of the BMW i4 also have the same amount of boot space, which is 470 litres with the back seats up and 1,290 litres with them folded down. It’s also worth remembering that the i4 is a practical hatchback with a large boot opening - the entire tailgate including the glass opens.

This means that access to the boot is impressive for this kind of car, especially in the sporty M50 model. The Tesla Model 3 has 425 litres of boot space, so the BMW is more practical than that, and the Polestar 2 has just 405 litres (rising to 1,095 litres with the seats folded). This means the i4 is one of the more practical cars of its type - though the Jaguar I-Pace is roomier, if you don’t mind the SUV looks and driving position.

BMW i4 towing capacity

Many electric cars aren’t legally allowed to tow trailers at all, because they have not been approved to do so, but the BMW i4 is not in that camp. In fact, it’s able to tow a reasonably strong 1,600kg with a braked trailer, which is likely to be enough for many people.

It’s not an ideal choice as a tow car, though, as pulling a heavy load behind you is going to seriously impact the car’s range and efficiency and you’ll have to stop many times to recharge along the way.

BMW i4 weight

Weight is a hugely important factor in how a car drives, and it affects things like performance, efficiency, handling and range. Electric cars tend to be on the heavier side because of their big battery packs, and if you look at the kerbweight figure for the i4, it’s clear that this is the case here

The lightest version in the range is 2,125kg, which is incredibly heavy for a car of this size. To put that into perspective, that’s about double the weight of a normal city car and potentially 500kg more than a similarly sized petrol or diesel car. The M50 model weighs even more, at 2,290kg. The Tesla Model 3 is lighter, at around 1,850kg, and the Polestar 2 is about the same as the BMW.
