Tesla Model Y showcases new tech that could revolutionize cabin designs [Feature]
During the IAA Mobility Show this year in Germany, Dirac and Trèves showcased revolutionary technology using a Tesla Model Y. Trèves’ new Sonified technology paired with Dirac OPTEO tuning teased the future of the car cabin at the event in Munich.
The Tesla Model Y’s journey with Trèves’ Sonified technology starts with a unique exciter design. Audio exciters are audio processing tools that manipulate sounds through synthesizing harmonics/harmonic distortion, usually in the high-frequency range. The new design was so exciting, Mark Cooper— Trèves Sr. VP of Global Sales and Product Lines—joked with Teslarati that the company considered spelling everything with a capital “X” as in eXciter.
Cooper knew Trèves developed something special with its new eXciter. Ironically, exciters aren’t that exciting in the automotive audio realm—despite their names. It would take someone with experience to realize the potential of Trèves’ unique eXciter design. Enter Dirac.
Hendrik Herman, Dirac’s Vice President of Automotive, shared his first experience and initial shock with Trèves Sonified technology.
“And so at one point, you know, we met, and I had the chance to listen to one of the demo cars in an earlier revision. And I need to admit [I] was a bit biased because exciters, in essence, have been around for audio reproduction in the past. But they never excited anyone—to be honest—because the performance back in the days or by, let’s say, competitors out there—setups that we had seen over the last maybe five to 10 years—simply were not what you were looking for.
“So as I said, I was very biased first meeting with Mark and team about, you know, having exciters, and I was like, ‘Yeah, well, not the exciter story again.’ But then I was astonished and surprised [at] how well it was working. I mean, it was perfectly integrated. And it was a completely different experience,” Herman told us.
What is so different about the Trèves eXciter?
So what actually makes the Trèves eXciter revolutionary? Essentially, Trèves reimagined the design of an audio exciter—sort of like Tesla reimagined the idea of a car to develop its electric vehicles today—and started from the ground up.
“The head of innovation was working with a friend on what [we could] do with these fabulous exciters but differently. And that’s what we’ve done: basically, rather than have the exciter stuck on a piece of hard trim that rattles, it’s inside the soft trim. And that’s where it’s easy to understand the difference: soft trim doesn’t rattle,” Cooper shared.
The difference between Trèves’s eXciter design and other companies’ designs appears to start from their perspectives. Typically, new eXciter designs would come from companies specializing in audio. They usually focused on replacing the loudspeaker with new audio exciters and placing them in the same places in cars.
Cooper explained that exciters would be placed on surfaces fixed onto car bodies with screws and pop rivets. Over time, the exciters would shake the surface, and the screws and pop rivets would come loose, resulting in a buzzing noise and terrible audio.
Trèves’s mother company, Trev, does not specialize in audio—hardware or software. It specializes in NVH and interior trim, providing a unique perspective to audio exciters. The Trèves eXciter is decoupled from the hard surfaces of a car’s body, effectively eliminating the buzzing noises and rattling caused by regular exciters. But it doesn’t end there. The redesigned eXciter also changes how sound is released, creating a new audio experience since loudspeakers were first placed in cars.
“So whether it’s been the Dirac guys or some of the other audio specialists when they’ve heard our cars, they said it sounds different from an out speaker. And that’s got people excited because loudspeakers have been in cars for like 50, 60 years. So we all know what they sound like,” stated Cooper.
What’s so exciting about the Trèves eXciter?
Better sound quality is not what makes the Trèves eXciter different—even though it does deliver better audio. What’s so exciting about the Trèves eXciter is how the sound travels out of it, creating a distinct sound experience and many possibilities for cabin car designs. Cooper summed the new eXciter’s unique capability the best.
“If you can imagine the loudspeaker, it’s [a] cone, and it creates like a column of air. And as the air moves, it makes the pressure in your ears. And that’s how the sound is transmitted, right. So you’ve got a column or a piston of air coming off the loudspeaker,” he said, guiding us through a mental experience of Trèves Sonified technology.
“What [Trèves does] is we have a plate of composite material, which is about the size of a hand, for example, in a headrest or under the seat. And as we move that whole surface together, the sound doesn’t come up in a piston; it sort of spills over the edge.
“Okay, so the actual source of the sound is not easily identifiable. And that’s where the audio industry is saying, for emissivity, which is exactly what Hendrik was talking about at the beginning. This is great because it allows us to put the source of the sound closer to the ear without making it directional. And that’s what’s got everyone so excited right now,” explained Cooper.
Trèves Sonified technology allows designers to reimagine a vehicle’s cabin since traditional loudspeakers could only be placed in certain areas of a car. The Trèves eXciter can be placed in other cabin areas, creating numerous possibilities—especially for automakers seeking to create cabins with better entertainment features.
Trèves and Dirac plan to team up again on another Tesla vehicle for CES 2024 in Las Vegas.

Starlink gets green light to launch internet services in Vietnam
Vietnam has given Starlink the green light. With mobile & aviation plans in the mix, SpaceX continues its push into Asia.
Starlink received the green light to launch its internet services in Vietnam.
The Vietnamese government noted SpaceX’s permission to launch Starlink services in the country is on a trial basis. Starlink’s trial period will last until the end of 2030. SpaceX has a subscriber limit of 600,000 within the trial period.
SpaceX can provide Starlink’s fixed and mobile internet service plans throughout Vietnam. It may also offer Starlink Aviation service plans.
According to Reuters, the Vietnamese government noted that there is no limit to foreign ownership of a service. It is uncertain if SpaceX has applied for a license to launch Starlink services in Vietnam.
Vietnam’s decision to permit Starlink services in the country differs from Italy’s decision to pause discussions regarding SpaceX’s internet service. According to Italy’s Defense Minister Guido Crosetto, discussions of a Starlink deal with SpaceX have “come to a standstill. Crosetto cites the controversy surrounding Elon Musk as the reason for the pause on a Starlink deal. Italy was discussing a potential $1.6 billion, 5-year Starlink contract with SpaceX.
SpaceX is also trying to launch Starlink in India. The aerospace company has already signed deals with two of India’s top telecom companies for Starlink services. However, Starlink is still waiting for regulatory approval.
While waiting for regulatory approvals and license processing, SpaceX continues to improve its Starlink services. Recently, news broke that the Elon Musk-led company has plans to launch a new Starlink dish with gigabit speeds.

Tesla UK celebrates momentous delivery milestone
Tesla just delivered its 250,000th EV in the UK, marking a major milestone! The lucky owners? A family of four who got a Model 3.
Tesla recently delivered its 250,000th electric vehicle (EV) in the United Kingdom (UK). The American EV maker delivered its 200,000th car in the UK on March 28, 2024.
The 250,00th Tesla vehicle delivered in the UK was handed over to the Cotters, a small family of four with two children. The Cotters received a Tesla Model 3, showing that it still has a place among families.
Tesla UK sales increased by over 20% in February, with almost 4,000 units sold. Last month, the Tesla Model 3 and Model Y ranked second and third, respectively, as the UK’s most popular cars. The Mini Cooper was the UK’s most popular car in February.
Tesla’s brand in the United Kingdom appears untainted by the recent controversy surrounding Musk, leading people in the United States to vandalize Tesla vehicles, stores, and Superchargers.
In the United States, the FBI has created a task force to squash Tesla attacks and end the acts of “domestic terrorism.” At least four people have been arrested related to Tesla attacks, one of which drove a car into a group of people protesting in front of a Tesla store. The other three allegedly threw Molotov cocktails at Tesla vehicles, stores, and Superchargers.
Wall Street analysts have acknowledged the adverse effect anti-Tesla sentiments could have on the company stock. However, the Tesla attacks have little to no impact on analysts’ recent Tesla target price estimates or predictions.
A few analysts have reduced their Tesla price targets as the first quarter ends. Wells Fargo’s Colin Langan cut Tesla’s price target to $130, while RBC slashed it to $320. However, some analysts maintained their price target, like Canaccord Genuity.
“Our estimate is informed by our opinion that some consumers are delaying vehicle purchases to access the new Model Y and 4Q24 earnings call commentary regarding Model Y-related factory retooling limiting production…We wonder whether purchase decision delays and production limitations are being misinterpreted as halted overall momentum for Tesla,” Canaccord analysts noted.

Here’s where Waymo is launching autonomous robotaxis next
Waymo has its sights set on three new U.S. cities in the months to come.
Google parent company Waymo has announced plans to bring its self-driving robotaxis to yet another U.S. city, adding to the list of those it plans to deploy the service to in the next several months.
On Tuesday, Waymo announced in a press release that it will be bringing its autonomous ride-hailing vehicles to Washington D.C. in 2026, after it recently announced plans to start deploying the services in Atlanta, Georgia, and Miami, Florida, sometime in 2025. The D.C. services will utilize the Waymo One app, unlike some of the cities which will roll out through a partnership agreement.
“Waymo One is making fully autonomous driving a reality for millions of people across the U.S.” said Tekedra Mawakana, Waymo Co-CEO. “We’re excited to bring the comfort, consistency, and safety of Waymo One to Washingtonians, those who work and play in the city every day, and the millions of people from around the world who travel to the District every year.”
The company says it plans to continue working closely with legislators on regulations needed to operate driverless vehicles in D.C. Additionally, Waymo says it’s currently operating over 200,000 fully autonomous, paid driverless ride-hails per week, as Tesla and others aim to enter the commercial robotaxi space in the coming months.
This video shows the strength of Tesla's vision-based approach.👀🤖

“I’ve experienced firsthand how safely the Waymo Driver operates around pedestrians, cyclists, and other vulnerable road users,” writes Jonathan Adkins, the CEO of the Governors Highway Safety Association. “Waymo has worked with GHSA and our first responder network as they’ve expanded their service, always putting safety first. As someone who walks to work almost every day, I’m excited to share the road with Waymo in Washington, D.C.”
Waymo also recently launched its robotaxi services will deploy in a partnership with Uber in Austin, Texas, where Tesla also has a so-called Gigafactory and plans to roll out its own robotaxi services later this year. The company currently operates paid driverless ride-hailing or early testing in the following cities, primarily in the U.S.:
- San Francisco, California
- Larger San Francisco Bay Area Metro, California
- Los Angeles, California
- Phoenix, Arizona
- Austin, Texas
- Miami, Florida (early pilot testing)
- Tokyo, Japan (early pilot testing)
The news also comes as Tesla aims to roll out its first unsupervised drives with its in-house Full Self-Driving (FSD) software this summer, along with rolling out initial robotaxi ride-hailing services. While the company doesn’t currently operate any paid ride-hailing like Waymo One, the company’s vehicles can generate real-time training data from drivers with FSD Supervised engaged.
