Tesla’s FSD continues to expand and learn, and V13 won’t be any slouch on this. V12 implemented end-to-end AI, and V13 brings a host of new features to help it reach feature completeness.
Today, FSD relies almost entirely upon visual data acquired from the vehicle’s cameras. Of course, it does pull information from other sensors, but the primary input is vision. While Tesla previously used radar in its vehicles and still ships the Models S and X with deactivated HD Radars, it relies on vision to guide its decision-making.
But that’s all changing—a revised version of V13 will bring audio-based decision-making to FSD for the first time. FSD is famously designed to work like a human driver—it relies on vision—but now it’ll also begin relying upon audio—both as an input… and an output.
We touched upon these items in our article on FSD V13, but it's time to really dig into them.
Listening for Emergency Vehicles
@steveshap.bsky.social
FSD will soon be able to detect emergency vehicles by analyzing the sounds it hears. Interestingly, this will be done through the internal microphone—the same one used for voice commands. That’s because sirens are loud—loud enough for humans (and microphones) to hear them inside a moving car.
This will enable FSD to identify the distinct sounds of an approaching siren - helping to ensure that FSD detects emergency vehicles earlier and takes the correct maneuvers to move out of the way and safely pull over.
In addition, by analyzing the actual sound of the incoming siren, FSD should also be able to make a reasonable determination about whether the siren is approaching or just echoing off the city streets using the Doppler effect and some fairly simple math.
With the release of FSD V13.2 to early access testers and now FSD 12.5.6.4, Tesla has added a new item to the release notes that lets drivers opt-in to sharing audio data. For users who opt-in to sharing this data, Tesla will now receive 10-second audio clips in certain situations. Tesla will listen for certain sounds and then send this data back to Tesla for further analysis. This will help them improve certain sound detections.
In the release notes, Tesla specifically mentions detecting emergency vehicles by sound, but it seems that it will also be used for other things, such as listening for other vehicles honking or potentially someone yelling at the vehicle. These additional capabilities will help FSD navigate a world made for humans, which couldn’t be done with vision alone.
FSD Will Honk
So we’ve covered inputs… what about outputs? Ashok Elluswamy, Tesla’s VP of AI, mentioned that FSD will gain the ability to honk. That means FSD will be able to provide an audio cue to other vehicles - just like a real, human driver would. Whether that’s someone cutting FSD off, or someone dozing off at a traffic light, FSD gaining the ability to honk will be extremely valuable - it’s the first ability FSD will have to communicate with the outside world and with other drivers.
Humans have developed different types of honks, such as short, friendly taps of the horn or louder, longer horn presses for emergency situations. It’ll be interesting to see if Tesla also implements different types of honks as well.
This is one of the key steps to humanizing FSD - one of the final puzzle pieces. This is expected to be the final set of inputs necessary for FSD to be able to drive like a human, and it’s exciting to see Tesla get so close with just vision.
FSD will soon be able to see, hear, and honk. Let’s just hope Tesla’s initial implementation for honking is better than Waymo’s (video below of Waymo vehicles honking repeatedly at 4 am).
Imagine being woken up at 4 a.m. by cars honking at each other. That's what some San Francisco residents have been dealing with for weeks, as the Waymos can be heard in this video honking and blinking headlights in a parking lot outside of their condo. https://t.co/2cVmDfUk4ipic.twitter.com/pkxNTT5vXd
Tesla has recently committed new code to its Light Show Github repository that reveals several additional Lightshow features and shares specifications for others.
Tesla hosts the software for building Lightshows on GitHub, an open-source code repository. The new code was added five days ago, but given that this is a change to the actual software and not an on-vehicle change, we’re not sure whether the features below will be available for immediate use or will be available in a future software update.
Up to Four-Hour Long Light Shows
The feature update is pretty extensive and, for the most part, is focused on the Cybertruck and Model 3 Highland, but also features changes for other Tesla models.
There’s one general change, which now lets you create Light Shows that are up to four hours in length — yes, that’s really long. In the Holiday update, Tesla mentioned that Light Shows can now be longer, but this recent commit makes it seem like Tesla is essentially removing the limit of how long a Light Show can be.
Front & Rear Light Bars
On the outside of the Cybertruck, you’ll now be able to control the front light bar, but what’s even better is that you can control each of the 60 LEDs individually. The rear light bar is seeing similar improvements, letting you control each of the 52 LEDs individually.
This feature alone is going to create some amazing Light Shows, anything from which has 60 individually configurable LEDs each. The rear light bar has 52 individually controllable LEDs as well.
This alone is going to inspire some really creative designs, such as a Knight Rider-like animation as seen on Rivian.
These are, of course, locked to just white for the front light bar and red for the rear, but Lightshow designers will be able to configure how bright each individual LED is and feather them up and down in brightness.
As we saw in the absolutely epic Tesla octa-truck Lightshow, the off-road lightbar is also controllable on vehicles that have it equipped. For now, that’ll just be Foundation-Series Cybertrucks, but the lightbar has been confirmed to be compatible with the non-Foundation-Series vehicles once it arrives in the Tesla shop later this year.
The off-road lightbar has six segments - two side-facing ditch lights and four forward-facing lights. Although you won’t be able to address individual LEDs here, you’ll be able to control each segment (six total) and brightness.
This feature was added as part of the Holiday update, so it should be available for all vehicles on 2024.44.25 and higher.
Center Display Color
Over on the interior side, designers will get full RGB control for the center display. Even when viewing the light show from the exterior of the vehicle, the center display will light up the interior in any color of your choice, letting you add festive colors to your Light Shows.
The interior display is also available on the Holiday update and is available for all vehicles, including legacy Model S and Model X vehicles that support Light Shows.
Ambient Lighting
This one has been a long time coming, but you’ll finally be able to control the vehicle’s ambient lighting feature on the Cybertruck and new Model 3. The accent lights are split into five segments and are all controllable RGB, so you can set each section to a different color if you want. The sections include center front, left and right front, and left and right rear.
These are some massive additions to Tesla’s Light Show feature, and they’re arguably some of the best. The individually controllable LEDs in the light bars and the ability to choose colors for the first time will undoubtedly create some of the best Light Shows we’ve ever seen.
Unfortunately, Christmas is behind us now, but we’re sure developers will find other holidays that take advantage of colors, such as Independence Day.
Light Shows bring the Tesla community together, and they’re one of the most distinctive Tesla features. Enjoy the awesome Christmas Light Show compilation below. Thanks to Rhys Samson for sharing these Light Show changes with us.
In an updated filing to the US Department of Energy, the Cybertruck is now eligible for the $7,500 USD EV tax rebate. However, what’s most interesting is that this same filing also confirmed the upcoming production of the Single Motor Rear Wheel Drive - for model year 2025.
Rear Wheel Drive
The Rear Wheel Drive Cybertruck was initially announced at the original Cybertruck reveal, but when the Foundation Series was announced, only the Tri-motor Cyberbeast and Dual Motor AWD models were made available. Tesla initially indicated that the RWD model would arrive sometime in 2025, but that text was later removed from the website.
In the second half of 2024, Tesla launched the non-Foundation series, but it once again arrived without mention of the RWD variant. Many have expressed a great amount of interest in the RWD variant, especially given the higher-than-expected pricing of the Cybertruck at launch.
Cybertruck EV Rebate
In addition to the reveal of the 2025 RWD variant, the Cybertruck is now also eligible for the US Federal EV Tax Rebate. For buyers of the vehicle, that means the AWD Cybertruck is now eligible for the full rebate if you don’t add any additional options since it needs to stay under the $80,000 cap.
FSD can still be added for $8,000 since it’s not considered a vehicle add-on and won’t count toward the total price of the truck. The incoming US Administration has already said it intends to cancel the US Federal EV Tax Rebate sometime in late January, so if you’ve been on the fence, this may be a good opportunity to buy the truck.
Here’s an updated price table for the Cybertruck, which includes pricing with and without the rebate for all three variants.
Variant
Price
After Rebate
RWD*
$60,990
$53,490
AWD
$79,990
$72,490
Cyberbeast
$99,990
Not Eligible
*RWD price has not been confirmed at this point.
The price for the RWD Cybertruck above is the price Tesla showed on their site before it was removed in August 2024.
If you use a referral code alongside the tax rebate, the AWD starts at $71,490. Some lease incentives can also drive that price down slightly if you choose a lease and then do a lease buyout at the end.
