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.

The Tesla Cybercab has been spotted testing on public roads for the first time, marking a substantial step forward in the vehicle’s development.

The car was spotted just minutes from Tesla’s Engineering Headquarters in Los Altos, California. There are a few interesting tidbits we can gather from the photo and the information shared with it:

The vehicle had a driver and side view mirrors equipped on it, which seems to be pretty expected, especially at this stage.

Tesla might have been using its Full Self-Driving software with the vehicle as it enters this new stage of testing on public roads. This seems most likely, especially as the car, which has long been developed to be void of a steering wheel and pedals, will totally rely on autonomous tech to transport one or two passengers to their destination.

Additionally, side view mirrors are required by law at delivery, and Tesla was likely looking to keep things as safe and elementary as possible, especially with this early stage of testing.

As this is the first time the vehicle has been spotted on public roads and the first time it was likely testing on them, Tesla was being cautious.

There have been a lot of developments with Cybercab over the past few weeks, as the car has been spotted testing on the Fremont Factory’s test track, units have been seen outside of Gigafactory Texas’s crash testing facility, and there has been some additional speculation about what the vehicle’s standard equipment will be.

There have also been quite a few job postings by Tesla for manufacturing and production roles related to Cybercab over the past few weeks.

Yesterday, Tesla’s Board Chair, Robyn Denholm, revealed that the company could end up building Cybercab with a steering wheel and pedals, contrary to what Tesla and CEO Elon Musk have wanted to do.

Tesla Cybercab might be getting a huge change

The vehicle has yet to reach that stage of regulatory testing, but Tesla wants to start volume production in Q2. If it wants to release the vehicle without any manual controls, that means that Full Self-Driving will need to be completed within the next eight months.

Tesla hints it could see ‘a few more vehicles’ released soon

Denholm said on CNBC yesterday that “we do have a few other vehicles coming out.”

Published

Tesla Board Chair Robyn Denholm hinted the company could see “a few more vehicles” coming out and being released soon, although there is no indication of what could be on the way based on her comments.

However, Tesla has hinted toward several potential releases in the coming years, as other executives, including Chief Designer Franz von Holzhausen, have talked briefly about what could be on the way.

Denholm said on CNBC yesterday that “we do have a few other vehicles coming out.”

It was a vague and almost cryptic sentence, as, in all honesty, it was not completely clear whether she was talking about recent releases that are just making their way to market, like the Model 3 and Model Y “Standard,” or new vehicles altogether.

Nevertheless, it’s worth dissecting.

Tesla “Standard” Models

On October 7, Tesla launched the Standard Model 3 and Model Y, stripped-down versions of their now “Premium” siblings. The Standard trims lack premium features like leather seats, a rear touchscreen, and a glass roof, among other features.

Tesla begins deliveries of its affordable Model Y Standard

These cars are just starting to be delivered for the first time, so it is possible that Denholm was referring to these cars.

Potential Model 2 Hint?

There has always been a looming vehicle model that many Tesla fans and owners have been intrigued by: the Model 2.

This car was hinted at being the $25,000 model that Tesla was rumored to be developing, and many thought that was the vehicle that would be released earlier this month, not the Standard Model 3 and Model Y.

Instead, the Model 2 could be something that would enable Tesla to reach an entirely new consumer base, including those who are not able to swing the payment for the company’s more premium offerings.

It seems Tesla will have to launch some sort of extremely affordable model in the future, and with the Cybercab being slotted at that rough price point, it would not be out of the question for it to be in the realm of possibility for future releases.

It’s worth noting, however, that it is probably unlikely this will happen. Tesla is so deadset focused on autonomy, it seems Cybercab would take extreme precedence over the unconfirmed “Model 2.”

Cybertruck-inspired SUV

Tesla fans have been begging the company to develop a full-size SUV that would compete with the Ford Expedition or Chevrolet Tahoe, but the company has not given any indication that this would be something it would build.

Nevertheless, there was a very subtle hint in a recent promotional clip that showed a Cyber SUV mock-up placed strategically next to a clay model of a Model 3:

Tesla appears to be mulling a Cyber SUV design

The Model X is simply not what people want when it comes to an SUV, as it does not have the seating capacity and cargo space that many need with a full-sized SUV.

This issue, in particular, has been one that has been extremely relevant to the company’s future lineup as consumers have shown they would be interested in a Tesla vehicle that fit this description.

Additionally, von Holzhausen said in September that a Cyber SUV or a smaller electric pickup with a more traditional design is “definitely things we’ve considered…We’re working on so many innovative and fun things.”

Tesla enters new stability phase, firm upgrades and adjusts outlook

Dmitriy Pozdnyakov of Freedom Capital upgraded his outlook on Tesla shares from “Sell” to “Hold” on Wednesday, and increased the price target from $338 to $406.

Tesla is entering a new phase of stability in terms of vehicle deliveries, one firm wrote in a new note during the final week of October, backing its position with an upgrade and price target increase on the stock.

Dmitriy Pozdnyakov of Freedom Capital upgraded his outlook on Tesla shares from “Sell” to “Hold” on Wednesday, and increased the price target from $338 to $406.

While most firms are interested in highlighting Tesla’s future growth, which will be catalyzed mostly by the advent of self-driving vehicles, autonomy, and the company’s all-in mentality on AI and robotics, Pozdnyakov is solely focusing on vehicle deliveries.

The analyst wrote in a note to investors that he believes Tesla’s updated vehicle lineup, which includes its new affordable “Standard” trims of the Model 3 and Model Y, is going to stabilize the company’s delivery volumes and return the company to annual growth.

Tesla launches two new affordable models with ‘Standard’ Model 3, Y offerings

Tesla launched the new affordable Model 3 and Model Y “Standard” trims on October 7, which introduced two stripped-down, less premium versions of the all-electric sedan and crossover.

They are both priced at under $40,000, with the Model 3 at $37,990 and the Model Y at $39,990, and while these prices may not necessarily be what consumers were expecting, they are well under what Kelley Blue Book said was the average new car transaction price for September, which swelled above $50,000.

Despite the rollout of these two new models, it is interesting to hear that a Wall Street firm would think that Tesla is going to return to more stable delivery figures and potentially enter a new growth phase.

Many Wall Street firms have been more focused on AI, Robotics, and Tesla’s self-driving project, which are the more prevalent things that will drive investor growth over the next few years.

Wedbush’s Dan Ives, for example, tends to focus on the company’s prowess in AI and self-driving. However, he did touch on vehicle deliveries in the coming years in a recent note.

Ives said in a note on October 2:

“While EV demand is expected to fall with the EV tax credit expiration, this was a great bounce-back quarter for TSLA to lay the groundwork for deliveries moving forward, but there is still work to do to gain further ground from a delivery perspective.”

Tesla has some things to figure out before it can truly consider guaranteed stability from a delivery standpoint. Initially, the next two quarters will be a crucial way to determine demand without the $7,500 EV tax credit. It will also begin to figure out if its new affordable models are attractive enough at their current price point to win over consumers.
