NIO ET7 audio system reveals how important software will be in future vehicles [Editorial]
NIO went the extra mile—and then some—when it conceptualized the audio system for the ET7. The NIO ET7 has 23 speakers powered by Swedish digital audio pioneer Dirac’s Opteo Professional audio software and Dolby Atmos technology.
NIO and Dirac’s work on the ET7’s audio system reveals the changing design of the car’s cabin and the role software plays in its redesign.
The NIO ET7’s Sound
Every automaker has a specific sound they would like their passengers to enjoy in their vehicles. NIO also has a particular sound target, and for the ET7, the Chinese automaker wanted it to come through crystal clear.
NIO worked closely with Dirac to create its sound. The NIO ET7’s official online page states that the four-seater car has 23 speakers, four overhead speakers, and a subwoofer. It also has a 20-channel amplifier and comes standard with Dolby Atmos Technology.
NIO didn’t just add lots of speakers to the ET7, though. The China-based automaker together with Dirac were meticulous and intentional with the ET7’s audio system.
Redefining the Cabin
Audio experts must consider the environment the sound will be played in, making it challenging to work with vehicles. Lars Carlsson, the Head of Business Development Automotive Audio and Vice President at Dirac, told Teslarati that audio experts have to consider many things when creating the perfect sound inside a vehicle. They have to consider the number and position of the speakers and the number of seats in the vehicle. Audio experts must also consider how sound reflects on the cabin’s different surfaces and windows.
Each speaker output in the NIO ET7 was measured with 16 microphones, positioned in each seat for a total of 64 measurement positions in the cabin. The measured data gave Dirac a good overview of the acoustic performance of the car’s cabin and creates the base for Dirac’s patented algorithms to optimize the sound.
“We base everything on measurements and data. Our process really saves audio engineers a lot of time. They can tune on their computer instead of spending weeks in the car,” Carlsson said.
After measuring the cabin, Dirac used algorithms to “derive the optimum solution” for its sound field control technology. With sound field control, Dirac created “super speakers” for the ET7. Typically, there are three speakers in a car door: low frequency, mid-range frequency, and a tweeter for the high frequency. Dirac uses sound field control to digitally align the speakers, making them collaborate to realize one full, quality sound.
“In addition our algorithm lets the speakers in the cabin and the subwoofer collaborate to create an even sound field in the car, which means we can actually create an equal audio experience in every seat. You get the voice right in front of you and a good imaging and a very even bass distribution and tight bass,” explained Carlsson.
Software’s Critical Role in Future Vehicles
Software is playing an increasingly important role in the auto industry as automotive OEMs and startups reconceptualize the idea of the vehicle. Now, automakers are reimagining the use of the car cabin as more vehicles integrate autonomous software.
Software lies at the center of redesigning the cabin space for passenger activities. Many automakers have started investing in software for their vehicles. For instance, Volkswagen invested €2 billion in a joint venture with China-based Horizon Robotics. And Stellantis launched a software development center in India recently.
Audio, in particular, is beginning to play a more significant role in the cabin as automakers introduce more types of media for passengers to enjoy while on the road. Electric cars coming out on the market have fun new features now, like karaoke, videos, games, and more which rely heavily on audio systems. However, it is autonomy that drives the cabin’s redesign.
“We have an enormous interest for our solutions because audio is getting more and more important in the car. This is true for electric cars because it’s a quieter environment but also when looking into autonomous cars, where maybe you’ll be working in your car, you’ll be listening to music, you’ll be watching videos, you’ll have maybe rotating seats,” said Carlsson.
“There’s a lot of challenges also coming ahead, but I would say that Dirac is very well equipped for future challenges because software for anything in the cars is key,” he added.

Elon Musk doubles down on Tesla Cybercab timeline once again
“Cybercab, which has no pedals or steering wheel, starts production in April,” Musk said.
CEO Elon Musk doubled down once again on the timeline of production for the Tesla Cybercab, marking yet another example of the confidence he has in the company’s ability to meet the aggressive timeline for the vehicle.
It is the third time in the past six months that Musk has explicitly stated Cybercab will enter production in April 2026.
On Monday morning, Musk reiterated that Cybercab will enter its initial manufacturing phase in April, and that it would not have any pedals or a steering wheel, two things that have been speculated as potential elements of the vehicle, if needed.

Musk has been known to be aggressive with timelines, and some products have been teased for years and years before they finally come to fruition.
One of perhaps the biggest complaints about Musk is the fact that Tesla does not normally reach the deadlines that are set: the Roadster, Semi, and Unsupervised Full Self-Driving suite are a few of those that have been given “end of this year” timelines, but have not been fulfilled.
Nevertheless, many are able to look past this as part of the process. New technology takes time to develop, but we’d rather not hear about when, and just the progress itself.
However, the Cybercab is a bit different. Musk has said three times in the past six months that Cybercab will be built in April, and this is something that is sort of out of the ordinary for him.
In December 2025, he said that Tesla was “testing the production system” of the vehicle and that “real production ramp starts in April.
Elon Musk shares incredible detail about Tesla Cybercab efficiency
On January 23, he said that “Cybercab production starts in April.” He did the same on February 16, marking yet another occasion that Musk has his sights set on April for initial production of the vehicle.
Musk has also tempered expectations for the Cybercab’s initial production phase. In January, he noted that Cybercab would be subjected to the S-curve-type production speed:
“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”
Cybercab will be a huge part of Tesla’s autonomous ride-sharing plans moving forward.

Tesla owners explore potential FSD pricing options as uncertainty looms
We asked Tesla owners what the company should price Full Self-Driving moving forward, as now it’s going to be subscription-based. There were some interesting proposals.
Tesla is starting the process of removing the ability to purchase the Full Self-Driving suite outright, as it pulled the purchase option in the United States over the weekend.
However, there has been some indication by CEO Elon Musk that the price of the subscription will increase as the suite becomes more robust. But Tesla finds itself in an interesting situation with this: the take rate for Full Self-Driving at $99 per month is about 12 percent, and Musk needs a significant increase in this rate to reach a tranche in his new compensation package.
This leaves Tesla and owners in their own respective limbos: Tesla needs to find a price that will incentivize consumers to use FSD, while owners need Tesla to offer something that is attractive price-wise.
We asked Tesla owners what the company should price Full Self-Driving moving forward, as now it’s going to be subscription-based. There were some interesting proposals.
Price Reduction
Although people are willing to pay the $99 per month for the FSD suite, it certainly is too high for some owners. Many suggested that if Tesla would back down the price to $49, or somewhere around that region, many owners would immediately subscribe.
Others suggested $69, which would make a lot of sense considering Musk’s obsession with that number.
Different Pricing for Supervised and Unsupervised
With the release of the Unsupervised version of Full Self-Driving, Tesla has a unique opportunity to offer pricing for different attention level requirements.
$50/mo for supervised.
$300/mo for unsupervised including insurance.— pɦoɿɟ pᴉʌɒp (@CSUDavid) February 15, 2026
Unsupervised Full Self-Driving would be significantly more expensive, but not needed by everyone. Many people indicate they would still like to drive their cars manually from time to time, but others said they’d just simply be more than okay with only having Supervised FSD available in their cars.
Time-Based Pricing
Tesla could price FSD on a duration-based pricing model, including Daily, Weekly, Monthly, and Annual rates, which would incentivize longer durations with better pricing.
Annually, the rate could be $999 per year, while Monthly would stay at $99. However, a Daily pass of FSD would cost somewhere around $10, while a $30 per week cost seems to be ideal.
These all seem to be in line with what consumers might want. However, Tesla’s attitude with FSD is that it is the future of transportation, and with it offering only a Monthly option currently, it does not seem as if it will look as short-term as a Daily pass.
Tiered Pricing
This is perhaps the most popular option, according to what we’ve seen in comments and replies.
This would be a way to allow owners to pick and choose which FSD features they would like most and pay for them. The more features available to you, the more it costs.
For example, if someone only wanted Supervised driving and Autopark, it could be priced at $50 per month. Add in Summon, it could be $75.
This would allow people to pick only the features they would use daily.
Tesla has left a single loophole to purchase Full Self-Driving outright. On Sunday, the option officially disappeared from the Online Design Studio in the United States, as Tesla transitioned to a Subscription-only purchasing plan for the FSD suite.
However, there is still one way to get the Full Self-Driving suite in an outright manner, which would not require the vehicle owner to pay monthly for the driver assistance program — but you have to buy a Model S or Model X.
Months ago, Tesla launched a special “Luxe Package” for the Model S and Model X, which included Full Self-Driving for the life of the vehicle, as well as free Supercharging at over 75,000 locations, as well as free Premium Connectivity, and a Four-Year Premium Service package, which includes wheel and tire protection, windshiel protection, and recommended maintenance.
🚨 Tesla increased the price of both the Model S and Model X by $10,000, but both vehicles now include the “Luxe Package,” which includes:
-Full Self-Driving
-Four years of included maintenance, tire and wheel repairs, and windshield repairs/replacements
-Free lifetime… pic.twitter.com/LKv7rXruml— TESLARATI (@Teslarati) August 16, 2025
It would also be available through the purchase of a Cyberbeast, the top trim of the Cybertruck lineup.
This small loophole would allow owners to avoid the monthly payment, but there have been some changes in the fine print of the program, as Tesla has added that it will not be transferable to subsequent vehicle owners or to another vehicle.
This goes for the FSD and the Supercharging offers that come with the Luxe Package.
For now, Tesla still has the Full Self-Driving subscription priced at $99 per month. However, that price is expected to increase over the course of some time, especially as its capabilities improve. Tesla seems to be nearing Unsupervised FSD based on Musk’s estimates for the Cybercab program.
There is the potential that Tesla offers both Unsupervised and Supervised FSD for varying prices, but this is not confirmed.
In other countries, Tesla has pushed back the deadline to purchase the suite outright, as in Australia, it has been adjusted to March 31.
