15-inch MacBook Air teardown reveals few changes from 13-inch model
Apple's 15-inch MacBook Air is similar to its 13-inch counterpart in more than name, with a teardown showing there to be relatively few internal differences between the models.

The 15-inch MacBook Air is best described as an upscaled 13-inch MacBook Air, with it adding a few minor tweaks to the preexisting design. A look inside the chassis of the new model demonstrates that the similarities go beyond the surface, with the insides being pretty similar as well.
The teardown by iFixit published to YouTube on Friday took apart the 15-inch MacBook Air, and revealed it is taken apart the same way as the 13-inch model, using identical screws and clips. After taking off the initial layer, the hardware is visibly similar to the 13-inch, except the 15-inch has a slightly different speaker setup, since the larger model has more.
Disassembly is a "miserable" experience, with the components assembled and overlapping each other in a "maze" that makes battery removal and taking out the logic board a tough challenge. That logic board also has "pretty much the same stuff" as the 13-inch version.
As part of the teardown, Apple's continued reliance of adhesive strips to hold the battery in place is thought to be unnecessary, given the sheer amount of components that have to be removed beforehand that also holds the cells in place.
That battery is a 66.5Wh construction using a large cell section flanked by four smaller cells. It is believed this arrangement is used to allow the fast-charging function to work at full capacity, since multiple cells are charged simultaneously.
The 15-inch MacBook Air scores a 3 out of 10 on iFixit's "repairability" scale. Apple can earn another two points for parts and manual supply, but due to its "unreliable release schedule," the points are being withheld from the score for the moment.

Letting the marketing department send the hardware VP on a tour to explain that adhesives caused 1 year extra development for a company like Apple... I don't need any of that. The late arrival of MBA 15 is not an Apple Maps moment. Let us celebrate that we have a great new Mac priced to sell from a more reasonable Apple. Next stop is to fix the iPad Air pricing.
I've purchased many components and tools from them over the years. I'm very happy with their excellent, step-by-step repair guides that they create for free, and knowing what kind of repairability score each repair has gives me an idea of the time and difficulty I'll be facing. Why you're offended by that is odd to me.
I have a Mac mini that will soon be getting more RAM. Without step-by-step instructions I wouldn't have had the confidence to go in blindly due to much needs to be taken apart. So why should iFixit give it a rest with their guides? Oh yeah, "nobody wants" to repair or upgrade devices themselves any longer because you don't.
Yes, there is some challenge to designing a "thinner" 15" laptop case but the rest of it is from the parts bins. The logic board in the 13", 15", Mac Mini and iMac are or should be near identical. Leaving only the addition of a larger battery.
Let's not make it sound like more than it is.
You also have no idea how many engineers Apple had working on all these components to make the 15" MBA. I know in the past Apple has pulled people off other teams to focus on secret projects so perhaps that's a variable you should consider now that we know Apple Vision Pro has been announced.
Personally, I'm glad that Apple put in the extra effort to make the 15" as close to the 13" in the design language and didn't end up going with the easier path of simply building a one-off design that conformed to the larger size and weight like with the aforementioned 17" PowerBook.
Let's not make it sound like you could've done better.
