One of the most welcome features of the recently refreshed 2026 Model S and Model X is the addition of a front bumper camera. Now, thanks to some clever work by the Tesla community, it has been confirmed that this highly requested feature can be retrofitted onto older HW4-equipped (AI4) Model S and Model X vehicles.

The discovery and first installation were performed by Yaro on a Model X, and Tesla hacker Green helped provide some additional insight on the software side.

Unused Port and a Software Switch

The foundation for this retrofit has been in place for a long time, laid by Tesla itself. All HW4-equipped Model S and Model X vehicles, even those built before the recent refresh, have an empty, unused camera connector slot on the FSD computer, seemingly waiting for this exact purpose.

While the physical port is there, getting the car to recognize the camera requires a software change. According to Green, a simple configuration flag change is all that is needed to enable the front camera view on the vehicle’s main display once the hardware is connected and ready.

The Hardware: Parts & Costs

Yaro, who performed the installation on a Model X, provided a detailed breakdown of the parts and approximate costs involved.

Front Camera - $200 USD
Bumper Grill (with camera cutout) - $80 USD
Bumper Harness - $130 USD
Washer Pump - $15 USD
Washer Hoses - $30 USD

The total cost for the Model X hardware comes to around $455 USD, which isn’t too expensive if you were to DIY it. Tesla’s Electronic Parts Catalog has some of these parts available for order, and some can be ordered via your local Service Center. Yaro did note that he had to jerry-rig the camera connector cable, having salvaged the cable from a different camera harness.

The Model S vs Model X

This is where the project varies significantly. For the Model X, the retrofit is relatively simple. Because the main bumper shape is the same, only the lower bumper grill needs to be swapped for the version with the camera opening, along with installing the camera itself and the washer hardware.

For the Model S, the process is a bit more complex and expensive. Due to the different shape of the pre-refresh bumper, the entire front fascia assembly must be replaced to accommodate the camera. This makes the project far more expensive and laborious.

DIY or Official Retrofit?

Not a Tesla App

Right now, this is only a DIY retrofit. Tesla hasn’t indicated that they intend to offer this as an official retrofit for older vehicles at this time, but given the fact that it isn’t too complex, we expect that there is a possibility that they may do so in the near future.

All in all, this is about 3-5 hours of labor for the Model X, and approximately 5-7 hours of labor for the Model S, based on the official Tesla Service Manuals, using the front fascia reinstall process as a guide.

That means if Tesla does offer this as a retrofit service, it will likely cost between $800 and $1,200 USD when factoring in Tesla’s labor rates, but the total cost will vary regionally.

For those who own an AI4 Model S or Model X, it could be possible to request service for this installation, but as far as we’re aware, there is no official service notice for this retrofit at this time.

What About the Model 3?

For owners of the refreshed Highland Model 3, the only vehicle now left without a front bumper camera, the possibility of a retrofit is still uncertain. It has been noted by Green that some, but not all Model 3s built in late 2024 have an empty camera port on the FSD computer. This inconsistency means that while a retrofit may be possible for a subset of Model 3s, it isn’t a guaranteed upgrade path like it is for the Model S or Model X.

Overall, it's a fantastic opportunity for owners of older Model S and Model X vehicles to get a slight hardware refresh, which can get them one of the best new features from the 2026 refresh.

Tesla Launches Live Dashboard for Puerto Rico’s Powerwall Virtual Power Plant (VPP)

Tesla has launched a brand new web dashboard providing a real-time view into its Virtual Power Plant (VPP) program in Puerto Rico, which now includes over 63,122 participating Powerwall owners. This dashboard provides a transparent, minute-by-minute view of how a massive, decentralized network of home batteries is actively working to stabilize the island’s power grid and prevent outages.

A Live Look at a Virtual Power Plant

The new public dashboard on Tesla’s website shows the collective output of the VPP, displaying how much energy the network of thousands of independent homes is charging with or discharging to the grid at any given moment. This initiative really shows the behind-the-scenes of just how Tesla’s Virtual Power Plant system works, and helps to explain the abstract concept of grid-forming and grid-stabilization in an easy-to-understand interface.

How a Community Becomes a Power Plant

The concept behind the Puerto Rico VPP is simple. Through the program, thousands of individual Powerwall units across the island collaborate to form a single “virtual” energy resource.

When Puerto Rico’s grid operator needs emergency power to handle a surge in demand or a sudden drop in supply, the VPP is automatically activated. Participating Powerwall units will automatically dispatch their excess stored energy to help provide power during outages and keep the community powered. VPP’s activation is nearly instant - Tesla works alongside the grid operator and updates their information every few seconds, ensuring that the grid is always kept stable.

Tesla uses their Opticaster management platform to aggregate the data provided by Powerwalls and then issues energy dispatch commands when the grid operator requests them. Because the control is cloud-based, adding more batteries to the network simply involves enrolling them. This same software is being used to manage Powerwall networks in California, Texas, Massachusetts, Australia, and the U.K.

This instantaneous coordinated effort provides support to the grid far faster than any typical power plant could, serving to stabilize the grid and prevent power outages and brownouts. Tesla’s VPP in Puerto Rico can deliver up to 50 Megawatts (MW) of clean and reliable energy to homes and businesses across the island. That’s enough to power about 200,000 homes, from just the 63,122 participating Powerwalls on the island.

Powerwall still prioritizes home backup, even when being used as a VPP. It automatically charges to 100% before a storm arrives. When a grid event (drawing power as a VPP) occurs, Powerwall will only supply a certain amount of energy that the owner has approved, leaving a safety net for themselves.

A Grassroots Solution to a Critical Infrastructure Problem

The significance of this program extends far beyond the technology or the payouts from the VPP program. For years, Puerto Rico has faced challenges with grid stability and reliability. Much of this has been caused by isolated and aging infrastructure, alongside repeated damage from hurricanes. Tesla’s VPP represents a grassroots, community-powered solution to this long-standing issue.

Instead of relying on large, centralized spinning power stations, the VPP leverages the assets of thousands of residents who have already invested in their own energy independence with Solar and Powerwalls. By allowing their home batteries to participate, these owners aren’t just protecting their own homes from blackouts or netting a tidy profit on selling energy back; they’re actively contributing to a more resilient and reliable power grid for their entire community.

This live dashboard is a fantastic example of all the good that Tesla has done with their advancements in energy infrastructure and the advantages of distributed batteries. Individual community members can better their communities by participating, while also improving their lifestyle with Tesla’s Powerwalls.
