NIO ET7 audio system reveals how important software will be in future vehicles [Editorial]

Published

on

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.

Cybertruck

Tesla launches new Cybertruck trim with more features than ever for a low price

This is a considerable upgrade to the Cybertruck Rear-Wheel-Drive that Tesla offered last year. It was discontinued after just a few months, but we still have yet to see anyone share pictures of it online.

Tesla has officially launched a new trim of its all-electric Cybertruck, which has more features than previous offerings at this price point, which is an incredibly good value.

Tesla is now offering the Cybertruck All-Wheel-Drive, and starting at $59,990, it appears to be a lot of truck for the money.

Along with the sub-$60,000 starting price, Tesla gives the Cybertruck AWD a 325-mile range rating, a powered tonneau cover that houses three bed outlets. It also has Powershare capability, coil springs with adaptive damping for a refined suspension feel, Steer-by-wire and four-wheel-steering, a 6′ x 4′ composite bed, a towing capacity of 7,500 pounds, and a powered frunk.

This is a considerable upgrade to the Cybertruck Rear-Wheel-Drive that Tesla offered last year. It was discontinued after just a few months, but we still have yet to see anyone share pictures of it online.

That truck did not have a power tonneau, did not have adaptive suspension, leather seats, or nearly any of the premium features in the upper-level trims. It was not a great deal, either. It was only a $10,000 discount from the next Cybertruck trim, which meant losing a motor and a lot of premium features for not that much of a savings.

This is a much better offering from Tesla and could help the company see a bit of a resurgence from a sales perspective. Although the Cybertruck is a popular vehicle from a fan perspective, it is not a great seller, and Tesla knows it.

Tesla Cybertruck undergoes interior mod that many owners wanted

Despite it being a crowd favorite, it was simply priced out of people’s budgets, so this All-Wheel-Drive configuration should be easier to handle financially for many of those who wanted the Cybertruck but not the price tag that came with it.

It is not a far cry from what Tesla priced back in 2019, as it unveiled three trim levels back in November, nearly seven years ago: a Single Motor for $39,990, a Dual Motor for $49,990, and a Tri-Motor for $69,990.

This new AWD trim is just $10,000 off from that price tag, and accounting for inflation, Tesla is pretty close.

Deliveries are expected to begin in June 2026.

Tesla dominated JD Power’s EV Owner Satisfaction ranking for 2026, grabbing the top two spots in the survey with the Model 3 and Model Y.

The two Tesla models grabbed the first and second spots, respectively, with scores of 804 and 797 out of 1,000 possible points.

Brent Gruber, Executive Director of JD Power’s EV practice, said:

“EV market share has declined sharply following the discontinuation of the federal tax credit program in September 2025, but that dip belies steadily growing customer satisfaction among owners of new EVs. Improvements in battery technology, charging infrastructure, and overall vehicle performance have driven customer satisfaction to its highest level ever. What’s more, the vast majority of current EV owners say they will consider purchasing another EV for their next vehicle, regardless of whether they benefited from the now-expired federal tax credit.”

JD Power’s study showed three key findings: Public charging satisfaction was higher than ever, premium BEVs saw more pronounced quality improvements, and BEVs held their satisfaction ratings compared to plug-in hybrid electric vehicles (PHEVs).

Tesla Grabs Top 2 Spots

Despite what some publications might try to make you believe, Tesla is still the cream of the crop when it comes to EV ownership, and real-world owners surveyed by JD Power will prove that to you.

The Model 3 was the highest ranking EV considered, with a score of 804, followed by the Model Y at 797, the BMW i4 at 795, and the BMW iX at 794. The segment average for “Premium Battery Electric Vehicles” was 786. The Cadillac OPTIQ (762), Rivian R1S (758), Lucid Air (740), Rivian R1T (739), and Audi Q6 e-Tron (690) all finished below that threshold.

Meanwhile, a separate category for “Mass Market Battery Electric Vehicles” had the Ford Mustang Mach-E as the EV with the highest rating at 760. The segment average for this class was 727.

Tesla Supercharging Improves Public Charging Satisfaction

JD Power said the availability of public charging is “by far the most improved index factor,” and that the consistent growth of publicly available charging has helped push many consumer sentiments in a positive direction.

Most of this is due to the Tesla Supercharger Network and its expansion. However, Tesla owners are also becoming more satisfied with the infrastructure after expanding access to other EV brands, the study said.

Musk company boycott proposal at City Council meeting gets weird and ironic

The City of Davis in California held a weekly city council meeting on Tuesday, where it voted on a proposal to ban Musk-operated companies. It got weird and ironic.

A city council meeting in California that proposed banning the entry of new contracts with companies controlled by Elon Musk got weird and ironic on Tuesday night after councilmembers were forced to admit some of the entities would benefit the community.

The City of Davis in California held a weekly city council meeting on Tuesday, where it voted on a proposal called “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies.”

The proposal claimed that Musk ” has used his influence and corporate platforms to promote political ideologies and activities that threaten democratic norms and institutions, including campaign finance activities that raise ethical and legal concerns.”

We reported on it on Tuesday before the meeting:

California city weighs banning Elon Musk companies like Tesla and SpaceX

However, the meeting is now published online, and it truly got strange.

While it was supported by various members of the community, you could truly tell who was completely misinformed about the influence of Musk’s companies, their current status from an economic and competitive standpoint, and how much some of Musk’s companies’ projects benefit the community.

City Council Member Admits Starlink is Helpful

One City Council member was forced to admit that Starlink, the satellite internet project established by Musk’s SpaceX, was beneficial to the community because the emergency response system utilized it for EMS, Fire, and Police communications in the event of a power outage.

After public comments were heard, councilmembers amended some of the language in the proposal to not include Starlink because of its benefits to public safety.

One community member even said, “There should be exceptions to the rule.”

Community Members Report Out of Touch Mainstream Media Narratives

Many community members very obviously read big bold headlines about how horribly Tesla is performing in terms of electric vehicles. Many pointed to “labor intimidation” tactics being used at the company’s Fremont Factory, racial discrimination lawsuits, and Musk’s political involvement as clear-cut reasons why Davis should not consider his companies for future contracts.

However, it was interesting to hear some of them speak, very obviously out of touch with reality.

Musk has encouraged unions to propose organizing at the Fremont Factory, stating that many employees would not be on board because they are already treated very well. In 2022, he invited Union leaders to come to Fremont “at their convenience.”

The UAW never took the opportunity.

Some have argued that Tesla prevented pro-union clothing at Fremont, which it did for safety reasons. An appeals court sided with Tesla, stating that the company had a right to enforce work uniforms to ensure employee safety.

Another community member said that Tesla was losing market share in the U.S. due to growing competition from legacy automakers.

“Plus, these existing auto companies have learned a lot from what Tesla has done,” she said. Interestingly, Ford, General Motors, and Stellantis have all pulled back from their EV ambitions significantly. All three took billions in financial hits.

One Resident Crosses a Line

One resident’s time at the podium included this:

He was admonished by City Council member Bapu Vaitla, who said his actions were offensive. The two sparred verbally for a few seconds before their argument ended.

City Council Vote Result

Ultimately, the City of Davis chose to pass the motion, but they also amended it to exclude Starlink because of its emergency system benefits.
