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.

Elon Musk is now a remote DOGE worker: White House Chief of Staff
The Tesla and SpaceX CEO Elon Musk is no longer working from the West Wing.

In a conversation with the New York Post, White House Chief of Staff Susie Wiles stated that Tesla and SpaceX CEO Elon Musk is no longer working from the West Wing.
As per the Chief of Staff, Musk is still working for DOGE—as a remote worker, at least.
Remote Musk
In her conversation with the publication, Wiles stated that she still talks with Musk. And while the CEO is now working remotely, his contributions still have the same net effect.
“Instead of meeting with him in person, I’m talking to him on the phone, but it’s the same net effect,” Wiles stated, adding that “it really doesn’t matter much” that the CEO “hasn’t been here physically.” She also noted that Musk’s team will not be leaving.
“He’s not out of it altogether. He’s just not physically present as much as he was. The people that are doing this work are here doing good things and paying attention to the details. He’ll be stepping back a little, but he’s certainly not abandoning it. And his people are definitely not,” Wiles stated.
Back to Tesla
Musk has been a frequent presence in the White House during the Trump administration’s first 100 days in office. But during the Q1 2025 Tesla earnings call, Musk stated that he would be spending substantially less time with DOGE and substantially more time with Tesla. Musk did emphasize, however, that DOGE’s work is extremely valuable and critical.
“I think I’ll continue to spend a day or two per week on government matters for as long as the President would like me to do so and as long as it is useful. But starting next month, I’ll be allocating probably more of my time to Tesla and now that the major work of establishing the Department of Government Efficiency is done,” Musk stated.

Tariff reprieve might be ‘Tesla-friendly,’ but it’s also an encouragement to others
Tesla stands to benefit from the tariff reprieve, but it has some work cut out for it as well.

After Secretary of Commerce Howard Lutnick made adjustments to the automotive tariff program that was initially announced, many quickly pointed to the reprieve as “Tesla-friendly.”
While that may be the case right now, it was also a nudge of encouragement to other companies, Tesla included, to source parts from the U.S. in an effort to strengthen domestic manufacturing. Many companies are close, and it will only take a handful of improvements to save themselves from tariffs on their cars as well.
Yesterday, Sec. Lutnick confirmed that cars manufactured with at least 85 percent of domestic content will face zero tariffs. Additionally, U.S. automakers would receive credit up to 15 percent of the value of vehicles to offset the cost of imported parts.
Big Tesla win? Sec Lutnick says cars with 85% domestic content will face zero tariffs
“This is ‘finish your cars in America and you win’,” Lutnick said.
Many were quick to point out that only three vehicles currently qualify for this zero-tariff threshold: all three are Teslas.
However, according to Kelley Blue Book’s most recent study that revealed who makes the most American cars, there are a lot of vehicles that are extremely close to also qualifying for these tariff reductions.
Tesla has three vehicles that are within five percent, while Ford, Honda, Jeep, Chevrolet, GMC, and Volkswagen have many within just ten percent of the threshold.

It is within reach for many.
Right now, it is easy to see why some people might think this is a benefit for Tesla and Tesla only.
But it’s not, because Tesla has its Cybertruck, Model S, and Model X just a few percentage points outside of that 85 percent cutoff. They, too, will feel the effects of the broader strategy that the Trump administration is using to prioritize domestic manufacturing and employment. More building in America means more jobs for Americans.

However, other companies that are very close to the 85 percent cutoff are only a few components away from also saving themselves the hassle of the tariffs.
Ford has the following vehicles within just five percent of the 85 percent threshold:
- Ford Mustang GT automatic (80%)
- Ford Mustang GT 5.0 (80%)
- Ford Mustang GT Coupe Premium (80%)
Honda has several within ten percent:
- Honda Passport All-Wheel-Drive (76.5%)
- Honda Passport Trailsport (76.5)
Jeep has two cars:
- Jeep Wrangler Rubicon (76%)
- Jeep Wrangler Sahara (76%)
Volkswagen has one with the ID.4 AWD 82-kWh (75.5%). GMC has two at 75.5% with the Canyon AT4 Crew Cab 4WD and the Canyon Denali Crew Cab 4WD.
Chevrolet has several:
- Chevrolet Colorado 2.7-liter (75.5%)
- Chevrolet Colorado LT Crew Cab 2WD 2.7-liter (75.5%)
- Chevrolet Colorado Z71 Crew Cab 4WD 2.7-liter (75.5%)
These companies are close to reaching the 85% threshold, but adjustments need to be made to work toward that number.
Anything from seats to fabric to glass can be swapped out for American-made products, making these cars more domestically sourced and thus qualifying them for the zero-tariff boundary.
Frank DuBois of American University said that manufacturers like to see stability in their relationships with suppliers and major trade partners. He said that Trump’s tariff plan could cause “a period of real instability,” but it will only be temporary.
Now is the time to push American manufacturing forward, solidifying a future with more U.S.-made vehicles and creating more domestic jobs. Tesla will also need to scramble to make adjustments to its vehicles that are below 85%.

Tesla Cybertruck RWD production in full swing at Giga Texas
Videos of several freshly produced Cybertruck LR RWD units were shared on social media platform X.

It appears that Tesla is indeed ramping the production of the Cybertruck Long Range Rear Wheel Drive (LR RWD), the most affordable variant of the brutalist all-electric pickup truck.
Videos of several freshly produced Cybertruck LR RWD units were shared on social media platform X.
Giga Texas Footage
As per longtime Tesla watcher Joe Tegtmeyer, Giga, Texas, was a hotbed of activity when he conducted his recent drone flyover. Apart from what seemed to be Cybercab castings being gathered in the complex, a good number of Cybertruck LR RWD units could also be seen in the facility’s staging area. The Cybertruck LR RWD units are quite easy to spot since they are not equipped with the motorized tonneau cover that is standard on the Cybertruck AWD and Cyberbeast.
The presence of the Cybertruck LR RWD units in Giga Texas’ staging area suggests that Tesla is ramping the production of the base all-electric pickup truck. This bodes well for the vehicle, which is still premium priced despite missing a good number of features that are standard in the Cybertruck AWD and Cyberbeast.
Cybertruck Long Range RWD Specs
The Cybertruck LR RWD is priced at $69,990 before incentives, making it $10,000 more affordable than the Cybertruck AWD. For its price, the Cybertruck Long Range RWD offers a range of 350 miles per charge if equipped with its 18” standard Wheels. It can also add up to 147 miles of range in 15 minutes using a Tesla Supercharger.
Much of the cost-cutting measures taken by Tesla are evident in the cabin of the Cybertruck LR RWD. This could be seen in its textile seats, standard console, seven-speaker audio system with no active noise cancellation, and lack of a 9.4” second-row display. It is also missing the motorized tonneau cover, the 2x 120V and 1x 240V power outlets on the bed, and the 2x 120V power outlets in the cabin. It is also equipped with an adaptive coil spring suspension instead of the adaptive air suspension in the Cybertruck AWD and Cyberbeast.
