A Tesla Model 3 Performance was recently modified by a UK-based exhaust system manufacturer, giving the electric sedan a range of active sounds to give it a “proper exhaust note and sound.”

YouTube channel Archie Hamilton Racing featured the Tesla Model 3 modified by Miltek Sport. The latter created the mobile app-based Active Sound Generator by that produces around 98 decibels of performance exhaust sounds.

“For some, the peace and quiet of a Tesla is the reason they buy the car. For us, it was the way the car drives, and the silence was something we saw as a project to overcome. Why can’t we have the best of both worlds?” Miltek Sport wrote on its blog.

The mobile app allows one to set the kind of sound the system will play and the sound changes as one steps on the accelerator of the Model 3. One can choose from the roar of a V10 or V12 engine, and Miltek Sport will reportedly add more to the list of active sound options in the future.

The host of the Archie Hamilton Racing and the spokesperson for Miltek Sport took the Model 3 Performance with Active Sound for a spin.

“With EVs, our roads aren’t ready for EVs… it’s too loud so when you’re driving along, you get a lot of road noise in the car. Sometimes…it’s just nice to have an engine burbling away rather than just tire and wind noise. It feels more natural to have that. With the EVs, yes, the performance is there on paper but it’s not emotive. There’s no feeling to it. What the sound does is give it some feeling and some heart,” a spokesperson said.

Electric cars are radically quieter than their internal combustion engine counterparts. Tesla owners, for example, may only encounter tire noises and wind resistance noise at higher speeds. An occasional whine of electric motors is present from time to time.

“It’s a very subtle noise and you’re right, it gives it character. I just feel like we’re in a normal life sports car now,” the YouTube host added.

Artificial engine sounds for electric cars is not really a new idea. In fact, authorities in the United States and Europe recommend electric and hybrid car manufacturers to give owners the ability to choose an engine sound they can use while driving at low speeds to alert pedestrians. Tesla competitor Porsche Taycan, for example, offers a $500 package for an Electric Sport Sound package that gives the electric sports car the howl of a high-revving V8 engine.

Tesla owners, on the other hand, commonly deal with cabin noises with additional door seals. The Palo Alto, California-based carmaker even designed acoustic foam-lined tires for a quieter interior cabin.

According to Miltek Sport, Active Sound might soon feature futuristic sounds comparable to Star Wars. For most Tesla owners who enjoy the quiet motors and their potent performance, the force in such modification might not be that strong.

Tesla Board member and Airbnb Co-Founder Joe Gebbia has loaded up on TSLA stock (NASDAQ:TSLA). The Board member’s purchase comes just over a month before Tesla is expected to launch an initial robotaxi service in Austin, Texas.

Tesla CEO Elon Musk gave a nod of appreciation for the Tesla Board member in a post on social media.

The TSLA Purchase

As could be seen in a Form 4 submitted to the United States Securities and Exchange Commission (SEC) on Monday, Gebbia purchased about $1.02 million worth of TSLA stock. This was comprised of 4,000 TSLA shares at an average price of $256.308 per share.

Interestingly enough, Gebbia’s purchase represents the first time an insider has purchased TSLA stock in about five years. CEO Elon Musk, in response to a post on social media platform X about the Tesla Board member’s TSLA purchase, gave a nod of appreciation for Gebbia. “Joe rocks,” Musk wrote in his post on X.

Gebbia has served on Tesla’s Board as an independent director since 2022, and he is also a known friend of Elon Musk. He even joined the Trump Administration’s Department of Government Efficiency (DOGE) to help the government optimize its processes.

Just a Few Weeks Before Robotaxi

The timing of Gebbia’s TSLA stock purchase is quite interesting as the company is expected to launch a dedicated roboatxi service this June in Austin. A recent report from Insider, citing sources reportedly familiar with the matter, claimed that Tesla currently has 300 test operators driving robotaxis around Austin city streets. The publication’s sources also noted that Tesla has an internal deadline of June 1 for the robotaxi service’s rollout, but even a launch near the end of the month would be impressive.

During the Q1 2025 earnings call, Elon Musk explained that the robotaxi service that would be launched in June will feature autonomous rides in Model Y units. He also noted that the robotaxi service would see an expansion to other cities by the end of 2025. “The Teslas that will be fully autonomous in June in Austin are probably Model Ys. So, that is currently on track to be able to do paid rides fully autonomously in Austin in June and then to be in many other cities in the US by the end of this year,” Musk stated.

Tesla China’s new vehicle registrations saw a notable rise in the week of April 21-27, 2025. Over the week, the electric vehicle maker’s registrations saw an impressive 51% week-over-week rise, suggesting that domestic vehicle deliveries are on the rise once more. 

Tesla China Results

In the week ending April 27, Tesla China saw 10,300 new vehicle registrations. This represents a notable rise from the company’s registration numbers in the past weeks of April. For context, Tesla China saw 3,600 registrations in the week ending April 6, 5,400 registrations in the week ending April 13, and 6,780 registrations in the week ending April 20, 2025.

Considering that April is the first month of the second quarter, expectations were high that Tesla China was allocating Giga Shanghai’s output for vehicle exports. With 10,300 registrations in the week ending April 27, however, it would appear that the company’s domestic deliveries are picking up once more.

Tesla China does not report its weekly sales figures, though a general idea of the company’s overall perforce in the domestic auto sector can be inferred through new vehicle registrations. Fortunately, these registrations are closely tracked by industry watchers, as well as some local automakers like Li Auto.

Tesla Model 3 and Model Y in Focus

Tesla China produces the Model Y and Model 3 in Giga Shanghai. Both vehicles are also exported from China to foreign territories. As per industry watchers, it would appear that both the Model 3 and Model Y saw an increase in registrations in the week ending April 27.
