## Sales Data Tells an Uncomfortable Story

Global EV adoption is accelerating. That much is unambiguous. What's less discussed is the compositional shift in what kinds of EVs people are buying — and what it means for actual emissions reduction.

In the United States, Europe, and increasingly China, the best-selling EVs are not the compact cars that dominated early EV discussions. They are large SUVs and crossovers. The Ford Mustang Mach-E, Tesla Model Y, Rivian R1S, BMW iX — these are not small vehicles.

## Why Buyers Upsize

The psychology is not hard to understand. For many buyers, an EV represents a significant premium investment. Given that premium, the incentive is to get the largest, most capable vehicle that fits within budget — which is the same logic that drives SUV purchases generally.

Range anxiety also plays a role. Larger battery packs reduce range anxiety, and larger vehicles accommodate larger packs. A buyer who is nervous about running out of charge is more likely to choose a vehicle with a 100kWh pack than one with 50kWh, even if their actual driving rarely tests the smaller battery.

The charging experience further reinforces this. SUVs typically have faster charging architecture and more consistent thermal management because they have more physical space for battery engineering.

## The Emissions Math

Here's the uncomfortable part: a 2,500kg electric SUV is not necessarily better for the climate than a 1,200kg efficient hybrid or small EV.

Manufacturing emissions for a large battery pack are substantial. A 100kWh pack requires roughly 3–4 times the raw material inputs of a 25kWh pack. The lifecycle emissions advantage of a large BEV over a small efficient hybrid narrows significantly in high-carbon grid contexts.

In France (nuclear-heavy grid), a large BEV is clearly better. In Poland (coal-heavy grid), the calculation is significantly less favorable.

## Industry Response

Automakers are caught in a difficult position. Making large, profitable SUVs funds the R&D for smaller, less profitable vehicles. Denying consumers what they actually want to buy solves nothing commercially. The regulatory response — fleet average emissions standards — creates incentives to offer small EVs (to average down fleet emissions) while still selling large ones (where margins are).

The result is a market with an increasingly full range of EV options, but consumer demand concentrated in the large-vehicle segment. Whether this produces the emissions outcomes that EV adoption was meant to achieve depends heavily on how grids decarbonize over the next decade.
