Longtime Tesla hacker shares Model Y “E41” early details

Max Headroom 2025.09.23 3 min read

Longtime Tesla hacker @greentheonly has shared early firmware insights about the long-rumored affordable Model Y variant, which is reportedly codenamed “E41.”

The hacker hinted at a vehicle with a significantly simplified cabin, downgraded components, and cost-saving measures.

Simple and affordable

As per the longtime Tesla hacker, the Model Y E41 will have its own distinct fascia. The vehicle will also have a cabin that’s notably more minimal than the standard Model Y. Key changes reportedly include a fiberglass headliner, simplified cabin lighting limited to the footwell, single-axis seat controls, and no power folding mirrors.

Other reductions reportedly include no puddle lamps, no second-row display, no TPMS, and no glass roof. Audio will reportedly come in two configurations, “essential” or “essential with commodity.” The backup camera also loses its heater, and the console excludes the “airwave” feature.

The Model Y E41’s wheels are reportedly at 18 inches, and the suspension appears downgraded. While exact motor specs remain unknown, the veteran Tesla hacker noted that the vehicle will likely offer both RWD and AWD trims.

as I am looking more into it:
there’s going to be RWD and AWD trims.
Both have special motor configurations, though no idea what the motors would be.

Let’s see if may be I can get internal renders next.

Early production and potential rollout

Previous firmware observations suggest that Tesla may already be producing Model Y E41 prototypes on non-specialized factory lines, at least if the rollout pattern of past Model Y and Model 3 refreshes were any indication. With this in mind, the Tesla hacker noted that it would not be surprising if the vehicle were already being made in significant volumes today.

Reuters previously reported the E41 will be at least 20% cheaper to manufacture than Tesla’s standard Model Y, allowing the vehicle to become a lower-cost alternative for consumers who wish to enter the ecosystem without shelling out too much. While official pricing and details remain unconfirmed, @greentheonly’s recent insights provide a pretty exciting teaser at how Tesla might package its budget-friendly Model Y.
