Tesla Model Y L Powered Sub Trunk: 4 Details That Matter

A powered sub trunk has been spotted in the Tesla Model Y L — and Tesla hasn't said a word about it. Whole Mars Catalog flagged the feature on X early Tuesday morning, sharing photos of what appears to be a motorized sub-trunk lid on the long-wheelbase Model Y variant. Here's what the observation tells us, what context we can add, and what remains unknown.

1. This Is the Model Y L — Not the Standard Model Y

The powered sub trunk has been observed specifically on the Model Y L, the long-wheelbase six-seat variant that launched in China in August 2025 and began arriving in US showrooms in July 2026. The standard Model Y Juniper refresh introduced hands-free opening for the main rear liftgate and electrically folding rear seats — but not a motorized sub-trunk lid. If this feature is exclusive to the Model Y L, it would represent a meaningful hardware differentiation between the two variants, not just a software gap.

2. Tesla Has Never Announced This Feature

There is no mention of a powered sub trunk in any official Tesla release notes, spec sheets, or product pages as of this writing. That makes it an undocumented change — discovered through owner observation rather than a Tesla announcement. The evidence here is photographic: Whole Mars Catalog shared images of the feature in action. It's worth noting that Tesla has a history of quietly shipping hardware-level upgrades without press releases, particularly on newer or market-specific variants before a broader rollout.

3. The Sub Trunk Already Had Substance — This Adds Convenience

The Model Y's underfloor sub-trunk compartment isn't new, but it's genuinely useful storage. UAE-spec Model Y Long Range variants, for example, carry an 87-liter waterproof underfloor space. Tesla has also sold accessories designed specifically for the sub-trunk, including a Dual Zone Fridge ($595) and a Sub-Trunk Organizer ($115) — both pointing to how seriously owners use this space. A powered lid would make accessing that compartment hands-free, which matters most when your arms are full of groceries or gear. It's a small quality-of-life upgrade that fits the direction Tesla has been moving with the Juniper platform.

4. Availability Beyond the Model Y L Is Unclear

Right now, there's one confirmed sighting on one specific variant. Whether this feature will appear on standard Model Y units, whether it requires specific hardware already installed at the factory, or whether it could theoretically arrive via a software update on existing vehicles — none of that is known yet. Given that the Model Y L has a slightly different rear architecture to accommodate the third-row seating and extended wheelbase, it's possible the powered mechanism is specific to that body configuration. Owners of standard Model Y Junipers shouldn't expect this to appear overnight, but it's worth watching for additional reports as more Model Y L units reach customers.

What to Watch For

If you own a Model Y L, check your sub trunk — specifically whether the lid opens with a button, a foot gesture, or a touchscreen control. Reports from early owners will help establish whether this is a standard fitment across all Model Y L builds or something that varies by region or trim. As more units ship in the US and elsewhere, the picture should become clearer quickly.
