When you're looking at BMW's electric offerings, the i4 and i5 often come up in conversation. They share that unmistakable BMW DNA, promising a blend of performance and luxury. But as you start to dig into the specifics, a key question often arises: how do they stack up in terms of size? It's a practical consideration, especially if you're thinking about garage space, passenger comfort, or cargo capacity.
Let's get straight to it. The i4, while feeling substantial and sporty, slots into the 'mid-size car' category. Think of it as the electric equivalent of the familiar 4 Series Gran Coupe. Its dimensions are 4785mm in length, 1852mm in width, and 1455mm in height, with a wheelbase of 2856mm. This gives it a sleek, athletic profile that's undeniably BMW.
Now, the i5. This is where things shift up a notch. The i5 is BMW's foray into the 'large car' segment, akin to the electric version of the 5 Series sedan. It's noticeably bigger across the board. We're talking about a length of 5175mm, a width of 1900mm, and a height of 1520mm. Its wheelbase stretches to a generous 3105mm. That extra length and width translate into a more commanding presence on the road and, importantly, more interior space.
So, what does this size difference mean in practice? For starters, the i5's longer wheelbase generally translates to more legroom for rear passengers. If you frequently ferry adults in the back, the i5 will offer a more comfortable experience. The wider body of the i5 also contributes to a roomier feel inside, both for occupants and potentially for wider items in the cargo area.
Speaking of cargo, the i4 offers a hatchback-style trunk with a decent capacity of 470 liters, expandable to 1290 liters with the rear seats folded down. This versatility is a hallmark of the Gran Coupe design. The i5, being a more traditional sedan in its body structure (though the reference material notes it as a 'three-box car' with 4 doors, unlike the i4's 5-door hatchback), doesn't explicitly list a comparable folding seat cargo volume in the provided data, but its larger overall dimensions suggest a substantial trunk space, likely prioritizing depth and width for luggage.
On the road, these size differences can also influence handling dynamics. While both are engineered for that signature BMW driving feel, the i5's larger footprint and longer wheelbase might offer a slightly more stable and composed ride, especially at higher speeds or over longer distances. The i4, being more compact, might feel a touch more agile and nimble in tighter urban environments or on winding roads.
Ultimately, the choice between the i4 and i5, from a size perspective, boils down to your priorities. If you're looking for a sporty, stylish electric sedan that's still relatively easy to maneuver and park, the i4 is a fantastic option. If you need more passenger space, a more substantial road presence, and potentially a bit more cargo flexibility in a larger package, the i5 steps up to the plate. It's a classic BMW dilemma: choosing between refined sportiness and expansive luxury, now translated into the electric era.
