Tesla Makes Surprising Move: Drastically Reduces Speakers in Model Y RWD Variant

Tesla's approach to vehicle design has been about delivering maximum enjoyment, encapsulated in its aim to make cars "the most fun you can have in a vehicle." That’s why it's such a head-scratcher that the company has removed speakers from the most popular car in its lineup.

The Model Y RWD now includes a "Custom Audio" system, scaling down to seven speakers with a single amplifier and, notably, the absence of a subwoofer (h/t Drive Tesla Canada). This reduction from the previously lauded 13-speaker arrangement, including a subwoofer and two amplifiers, marks a significant shift in Tesla's audio offering for this model.

Audio Downgrade Detailed

The change raises questions about the impact on the overall audio experience, especially given Tesla's emphasis on the sound quality in their vehicles as part of the fun driving experience. Tesla has invested significantly in audio technology, drawing expertise from high-end audio brands like Bang & Olufsen.

The company’s dedication was highlighted in a Tesla-produced video showcasing the meticulous engineering behind its sound systems. The video emphasized the substantial size of the subwoofer in the Model Y and its integration into the vehicle's design, enhancing the overall audio experience without compromising space or aesthetics.

This RWD Model Y initially shared the same Premium Audio sound system as its Long Range and Performance counterparts, featuring 15 speakers, including two amplifiers and a subwoofer. This setup was somewhat unexpected since Tesla typically reserves high-end audio equipment for its upper-tier models. The subsequent reduction of speakers to 14 in late 2021, with the removal of the center instrument panel speaker, was considered an imperceptible change by Tesla. However, the newest adjustment is more substantial.

Other Models Impacted?

One can only assume the Model 3 will get the same treatment. However, the refreshed Model 3 is starting to show up in North America. Its upgraded stereo system has been well documented. Reducing this incredible system in entry-level RWD Model 3 would be a shame.

Interestingly, this update is specific to North America's Model Y RWD versions. The European Model Y RWD, manufactured at Giga Shanghai or Giga Berlin, retains the Premium Audio sound system. The LR and Performance variants of the Model Y continue to be equipped with the original 13-speaker system, including a subwoofer and dual amplifiers.

Tesla has not specified which seven speakers remain in the Model Y RWD's revised audio setup. With the change only recently added to the website, it may take some time before the first deliveries of the Model Y with the updated sound system occur, allowing for a comprehensive assessment of the new audio quality.

Tesla's decision to modify the Model Y RWD's audio system aligns with its strategy of varying features across different models, and it stands in contrast to its well-established commitment to exceptional sound quality. This development is particularly intriguing given the company's reputation for creating vehicles that deliver an exceptional and fun driving experience, of which the audio system has been a significant component.

Tesla Smoking While Supercharging? A Look at What's Actually Happening

By Karan Singh

Winter is here, and temperatures are dropping, so one of the most common Tesla questions is about to resurface.

If you’ve landed here after frantically searching about “smoke” coming from your Tesla while Supercharging, take a deep breath—it’s completely normal.

Tesla Smoking While Charging

If you’re Supercharging in freezing weather—even with preconditioning—you might notice steam rising from your Tesla. But rest assured, your car isn’t smoking.

Your Tesla’s heat pump is hard at work warming both the cabin and battery to keep you comfortable and ensure optimal charging temperatures. Over time, condensation and ice build-up in the heat exchanger coils.

Why Does It Happen?

When you reach a Supercharger with your vehicle, the heat pump is still running hot, but without the cold air from driving to keep the heat exchanger coils cool, the ice and condensation quickly start to evaporate—creating what looks like smoke.

Since this typically happens near the front of the vehicle, where a car would traditionally have an engine, new vehicle owners can be startled by the discovery. However, rest assured that it’s just water vapor and it’s completely normal in cold weather.

In fact, this behavior can be experienced in any EV with a heat pump in cold climates. So, if you saw steam coming out of your vehicle and panicked, don’t worry—you’re not alone.

Now that you know what’s happening, go ahead and Supercharge with confidence.

Tesla Improves YouTube App With Smoother Playback

By Karan Singh
Not a Tesla App

Tesla made a lot of improvements in the 2024 Holiday Update, including more than 15 undocumented improvements that were included in the release. One of these was a stealthy performance improvement to the YouTube app.

Several people have mentioned they’ve seen improved performance on YouTube since this year’s Holiday Update - and there’s an interesting reason why.

YouTube Improvements

The improved YouTube performance in Tesla vehicles comes from an unexpected source—Tesla actually rolled back support for YouTube’s newer AV1 video encoding. Instead, vehicles now default to the older VP9 encoding standard.

While AV1 is highly efficient in terms of bandwidth, it requires considerably more processing power to decode and display videos. VP9, on the other hand, is less computationally demanding but uses more bandwidth to achieve the same video quality. This trade-off means smoother playback and better overall performance, even if it comes at the cost of slightly higher data usage.

Intel Inside

The VP9 video codec that the YouTube app is now using is much easier to decode, making it less taxing on the vehicle’s processor. This change is particularly beneficial for Tesla vehicles with Intel processors, which previously struggled to stream video at just 720p. When using AV1, these vehicles often experienced stuttering, sometimes forcing the YouTube app to automatically downgrade playback to 480p.

With this update, Intel-based Teslas should now be able to stream at 1080p smoothly. Streaming at 1440p is also possible, although occasional stutters still occur as the system keeps up with the decoding process.

Intel-based vehicles are the big winners with this change, but this appears to affect AMD Ryzen-based infotainment units as well, providing even smoother playback.

Chromium Web App

Tesla’s Theater apps aren’t native applications; instead, they run as chromeless web apps, leveraging the open-source browser built into Teslas known as Chromium (the open-source version of Chrome). Although this works quite well, there is a severe limitation - Chromium hardware acceleration isn’t supported on Linux, the operating system Tesla uses for their OS.

As a result, Tesla vehicles rely on software decoding instead of hardware decoding, which would otherwise handle video playback far more efficiently. A potential solution could be for Tesla to transition away from Chromium-based web apps in favor of a Mozilla Firefox-based browser, as Firefox does support hardware acceleration on Linux. This switch could also open the door to better streaming performance and the possibility of expanding Tesla’s in-car entertainment options.

However, Tesla’s choice of Chromium likely stems from Digital Rights Management (DRM) requirements for streaming services like Disney+ and Netflix, which rely on DRM-enabled playback. Firefox on Linux has had inconsistent support for DRM due to codec availability and variations in operating system versions.

We’re hopeful that Tesla will either adopt Firefox or develop a fully native application to improve video streaming, rather than continuing with the current web-based Tesla Theater. This shift could also pave the way for additional in-car applications built on Tesla’s native Linux environment—perhaps even reviving the long-rumored Tesla App Store.

Regardless, this update is a welcome improvement, particularly for YouTube, which remains one of the most widely used Theater Mode apps due to its accessibility, free content, and mix of short and long-form videos. It remains to be seen whether similar improvements are made for Netflix, Disney+, or other streaming platforms.

If you’ve noticed improved performance in Theater Mode, now you know why.
