Which EVs Expose You to the Most EMF?

I lined up twenty-two of the most relevant electric cars on a single ruler. They are not equal — and the differences are not where you would guess.

Not all electric cabins are equal

In the first part of this series I made an argument that unsettles the usual story: the modern electric vehicle has quietly become a rolling robot, and the electromagnetic exposure that matters to the people inside it does not come from the battery — it comes from the radiofrequency and microwave layer of the sensor-and-automation architecture, the radars and cameras and antennas that a car now carries on its way to driving itself.

That was the idea. The obvious next question is the practical one: if that layer is what matters, then are all electric cars the same? They are not. Some cabins are far busier than others — and the interesting part is that the differences do not line up with price, with brand, or even with whether the car burns fuel at all. So I did the thing nobody in the public conversation seems willing to do. I put twenty-two of the most relevant electric vehicles of 2024–2026 on one common scale and ranked them.

One ruler for the whole fleet

To compare cabins honestly you cannot simply add up the power of everything transmitting inside them — the sources live in different frequency bands, pulse differently, and interact in ways a wattage total throws away. So, I use the analytical instrument I have developed for exactly this: an index that expresses the artificial electromagnetic complexity of a cabin as a single number, normalized to the one vehicle I have actually measured instrument-in-hand — the Tesla Model Y, set at 1.00.

Read the number simply: it is how much more, or less, artificial electromagnetic complexity a cabin carries relative to that measured baseline. Above 1.00 is busier than the car I measured; below it is calmer. Here is where the twenty-two land, grouped into four bands of exposure.

The full ranking, with each vehicle's exact index value and the architecture behind it, is in the whitepaper. Here I am showing you the shape of it.

What the ranking reveals

Look at the top of that list and a pattern jumps out. The busiest cabins — the Lucid Air, the Volvo EX90, the Mercedes EQS, the Kia EV9 — are the ones that stack the highest-consequence emitters together: LiDAR, radar aimed into the cabin, ultra-wideband keys, native 5G, and in several cases very high-voltage drivetrains. The calmest — the entry BYD models, the Mach-E — carry almost none of that.

Two things follow, and both are worth sitting with. First, the gradient is organized by modernity of the automation architecture, not by fuel type — which is exactly the thread this series keeps pulling. Second, and this is the part that should give us pause: the vehicle I measured, the Tesla Model Y (2021 – 2022), sits in the middle of the pack. Everything above it — the top nine cabins — represents an architecture denser than the one where I already documented real radiofrequency peaks and a measurable coupling of the field into the occupant's body. And those denser cabins have not been measured by anyone. They are inferred from their architecture, and they are exactly where the instruments should go next.

The silence around all of it

Here is the reflection I cannot get past, and it is not about any single car. Across every major jurisdiction — the United States, the European Union, the United Kingdom, China, South Korea, Japan — not one regulates the cumulative electromagnetic exposure of the person sitting inside a cabin. The frameworks that exist test devices one at a time; the standard reference limits are built around heating and six-minute averages, not the chronic, near-field, many-sources-at-once reality of a daily commute. The vehicle electromagnetic-compatibility rules check whether the car's electronics disturb each other — not whether the sum of them reaches the human being seated among them.

The scientific record is not silent, even if the regulators are. Large measurement programs, the debate over non-thermal biological effects, the reviews and the forceful rebuttals to those reviews — the evidence base is real, contested, and moving. I lay it out with citations in the whitepaper part 2 of this series. What I will say here is only this: a near-field, multi-source, chronic exposure that no framework anywhere evaluates is not a settled "safe." It is an open question that we have chosen, so far, not to ask.

Come read the whole thing

This is the public surface of the work: the shape of the ranking, the pattern inside it, and the reflection it forces. The full picture — every vehicle's exact index value, the architecture that drives it, the estimate of how much filtering each cabin would need to be brought back to coherence, and the regulatory analysis with its references — lives in the whitepaper that anchors this part of the series: "EVs: The Real EMF Emission Scenario."

I publish these blogs in the open because the reframing belongs in the open. But the detailed work — the numbers, the methodology, the model-by-model reading — I share with the circle of readers who follow this research closely at www.joaquinmachado.com. If the ranking above made you wonder where your own car sits, and what that actually means, that is the invitation. Come into the circle, and read the whitepaper that expands every finding gestured at here.
