Tesla Reduces Sentry Mode Power Usage in Update 2024.38

As part of Tesla software update 2024.38.4, Tesla has finally included updates to Sentry Mode to reduce its power consumption.

Sentry Mode is part of Tesla’s security system that keeps the vehicle sensors and cameras on to detect, record, and then inform the owner about suspicious activity. You can read more about it, including how much power it consumes, in our guide covering Tesla Sentry Mode.

Sentry Mode Battery Drain

Sentry Mode keeps the vehicle awake and continuously processes data from the vehicle’s eight cameras. However, due to the vehicle’s architecture and processing the multiple video feeds, Sentry Mode consumes a significant amount of power. Over a 24-hour period, an average Model 3 or Model Y will typically experience a battery drain of about 7-14% with Sentry Mode enabled, or roughly about one mile per hour.

While Sentry Mode is a great security feature, owners often have to decide whether the loss of range is worth the added security. Sentry Mode also becomes an issue when leaving your vehicle parked for an extended period of time, such as at the airport.

Sentry Mode Improvements

Tesla announced earlier this year that they were bringing significant efficiency improvements to Sentry Mode by cutting power usage by 40%.

Update 2024.38 is bringing about those changes. Tesla is changing the way its onboard computers process video to make Sentry Mode use much more efficient. Right now, the vehicle needs to keep its FSD and MCU (infotainment) computers on to process videos from the vehicle’s cameras. However, that’s changing with some architectural improvements in update 2024.38.

This change will arrive first with the Cybertruck in update 2024.38.4 and later. According to our source, it will also be available for other models in a future update, but Tesla is starting with the Cybertruck first.

Since most Cybertrucks have FSD included as part of the Foundation Series, they’re on FSD-specific updates, meaning that the number of Cybertrucks with update 2024.38 is extremely small. Once it becomes more widely available, we should be able to get some numbers to see how close Tesla got to its 40% power reduction.

Update: Read our follow-up story on the changes Tesla is making in the way it processes video to improve Sentry Mode’s power consumption.

Tesla Updates Santa Mode & Rainbow Road to Use Ambient Lighting and Updates SteamOS [VIDEO]

While Tesla’s 2024 Holiday Update brought many new features, including Apple Watch Support, Cross Traffic Alerts, Weather Overlays, Search Along Route, and others, there are also several smaller items in this update that didn’t get much attention.

Ambient Lighting Now Affects Rainbow Road & Santa Mode

The 2024+ Model 3 and Cybertruck both come equipped with ambient lighting, and Tesla is now taking advantage of this custom lighting feature by incorporating it into several easter eggs.

Rainbow Road: If you head over to Apps > ToyBox > Rainbow Road, you’ll find a new option available that allows the ambient lighting in the vehicle to also change shades while Rainbow Road is active. The Rainbow Road easter egg is a tribute to the iconic course course in Nintendo’s Mario Kart.

Check out the feature in action below:

Santa Mode: Just in time for Christmas, Tesla has improved Santa Mode by cycling the ambient lighting between Christmas colors. Similar to Rainbow Road, the use of ambient lighting for the easter egg is optional and can be enabled under Apps > ToyBox > Santa Mode.

When using Santa Mode with ambient lighting turned on, the lights will cycle just between Christmas colors, red, green and white, instead of the full rainbow. There’s a video of the feature below:

SteamOS (Beta) Update

The Model S and Model X vehicles that support Steam gaming are receiving a Steam app update in the holiday update as well. This update could end up being very interesting, but for now Tesla says that the SteamOS, which also runs on Valve’s Steam Deck has been updated to version 3.6.

Valve outlines a wide range of fixes and improvements in their release notes for version 3.6, but Tesla simply states that the OS update includes performance enhancements and improved game compatibility.

The SteamOS hasn’t been updated on the Model S and X for quite a while, so we believe there may be more to this besides performance improvements and fixes. We’ll be looking to share some insights into this in the near future.

So, there you have it—three new features in the Holiday update that have mostly gone under the radar. While they may not apply to everyone, there are plenty of other cool features in the Holiday Update, like the arrival of Dynamic Road Closure Routing and Nearby Parking, that are coming to every vehicle, so go check out the full release notes.

New Report Offers Specs & Price for Tesla's Upcoming Next-Gen Model

At the 2023 Q3 Earnings Call, Tesla provided an update on its next-generation model, what many are referring to as the “Model 2” or “Model Q.” Although the actual model name is yet to be determined, it is known internally as Redwood.

During the 2024 Shareholder Meeting, Musk again mentioned the upcoming model, saying that Tesla is working on new products, including a more affordable vehicle and a larger SUV.

While we know the next-gen vehicle is aimed at the $25k to $30k USD market, we now have some new information thanks to a new report out of China.

Launch & Price

According to the Chinese outlet CNMO Technology News (Sina Finance), Travis Axelrod, Tesla’s Head of Investor Relations, announced plans to launch a new model. Axelrod shared this update while addressing senior corporate investors at an investor conference hosted by Deutsche Bank on December 5, 2024.

The goal of Project Redwood, internally dubbed “Model Q” by Deutsche Bank, is to achieve a post-subsidy price of under $30,000 USD. With the Federal EV Rebate potentially expiring next year, this suggests that the Model Q’s starting price will be around $30,000 USD. For comparison, the Model 3 currently starts at $42,490 in the U.S.

We previously reported that Tesla has already been speaking to suppliers and is looking to begin volume production of the vehicle sometime around June 2025. Of course, prototyping is still necessary, but we haven’t seen any signs of Tesla testing a new vehicle since spotting the Cybercab on the streets ahead of We, Robot.

Specs

The Model Q will supposedly be about 15% smaller and 30% lighter than the Model 3, with an approximate length of 3,988mm, or 157 inches. For scale, the Mini is 157 inches, while the Model 3 is 185 inches, so it’s fairly compact.

The battery will also be smaller to match the vehicle’s smaller size as Tesla tries to reduce the vehicle’s price while maintaining a similar range as its other vehicles. Tesla is expected to offer two models—a single-motor RWD model and a Long-Range Dual-Motor AWD variant.

Variant

Motors

Battery Size

Estimated Range

RWD

1

53 kWh

230 miles (375km)

AWD

2

75 kWh

310 miles (500km)

There’s no news yet on the price of the AWD version, but we expect it to be about $5,000 more expensive than the RWD variant.

Once the vehicle ramps up in production, Tesla intends to produce about 10,000 of these per week globally or about 500,000 per year. As Tesla mentioned during one of their previous earnings calls, this next-gen vehicle will be built using Tesla’s current assembly lines with minimal changes. This should allow for a smoother and more predictable production ramp. While Tesla still plans to use its new unboxed assembly process, it’s now saving it for the robotaxi.

Project Juniper

One of the items that came up during the investor conference was Tesla’s Project Juniper—the Model Y refresh. Juniper has already had a few leaks, including some images and information that mention a return to the 7-seat, 3-row format—at least in China

We’re expecting Juniper to launch early next year, as production has supposedly already begun at Giga Shanghai, at least on a limited prototyping basis. If the rollout matches the Model 3 Highland refresh, we’ll see Juniper arrive in China first and then make its way to North America and Europe by the end of 2025. The performance variants should launch in early 2026, after the standard models.

If you’re excited about Juniper, so are we! Check out our wishlist of features for Tesla’s Model Y refresh, and see everything we know so far.
