What’s the Best Way to Insulate and Soundproof the Cabin of a Tesla Model 3?

For those of you who are Tesla Model 3 owners, you’ll likely agree that the car is a marvel of modern engineering. The all-electric vehicle boasts impressive acceleration and handling, a sleek and modern interior, and an unrivalled suite of advanced safety features. However, as with any vehicle, it isn’t perfect. One of the common complaints from owners is the level of noise inside the cabin, particularly when driving at highway speeds or on uneven road surfaces. This article will delve into several solutions that can help to address this issue, detailing the best products and accessories available for insulating and soundproofing the cabin of your Tesla Model 3.

The Sound Environment Inside a Tesla

Before we delve into solutions, it’s crucial that we understand the sources of noise inside a Tesla Model 3. The primary causes can be categorised into wind, road, and vehicle noise. Wind noise gets louder as you drive faster, with the sound created as air rushes past the car’s exterior. Road noise is caused by the vehicle’s tires making contact with the road, with the sound amplified based on the type of road surface and the speed of the car. Vehicle noise includes sounds produced by the car’s systems, such as the ventilation or even the electric motors.

Whilst electric cars like the Tesla Model 3 are inherently quieter than their gasoline-powered counterparts, they aren’t completely silent. The reduced engine noise can make other sounds more noticeable, such as the aforementioned wind or road noise. Thus, it’s essential to adequately insulate and soundproof the vehicle to ensure a comfortable and peaceful driving experience.

Noise Reduction Accessories for Tesla Model 3

The market is awash with accessories designed to reduce noise inside a Tesla Model 3. From door seals to trunk kits and interior accessories, there are several products that can help to significantly reduce the amount of noise permeating the cabin.

Door seals are an effective and affordable solution for mitigating wind noise. These rubber accessories fit into the gaps around the car doors, providing an extra layer of insulation. When installed correctly, door seals can dramatically reduce wind noise, as well as prevent dust and water ingress.

Trunk kits are also available as an aftermarket accessory for the Tesla Model 3. They typically come in the form of rubber mats that fit into the trunk space, absorbing sound and reducing resonance.

Lastly, interior accessories like insulation mats, lined with sound-absorbing materials, can be installed beneath the cabin’s carpeting or under the seats, effectively reducing road and vehicle noise.

Tesla Wheel Choices and Tire Types

Your choice of wheels and tires can also have a considerable impact on the amount of road noise in your Tesla Model 3.

Larger wheels can often generate more noise than their smaller counterparts, due to the reduced amount of tire rubber on the road surface. Tesla offers the Model 3 with several wheel options, ranging from 18-inch Aero wheels to larger 20-inch Performance wheels. Opting for the smaller wheels could help to reduce road noise.

In terms of tires, those with a softer compound or higher profile are generally quieter. While they may wear out faster, they can drastically reduce road noise due to their ability to absorb more vibrations.

DIY Noise Reduction Solutions

If you are handy and prefer the DIY approach, there are several solutions available to reduce cabin noise in your Tesla Model 3.

One popular DIY method involves the application of sound-deadening materials throughout the vehicle. These products, commonly referred to as "damping mats," can be applied to the interior of the car’s doors, roof, trunk, and floor.

Another solution is to apply a layer of rubberized undercoating to the vehicle’s underbody. This acts as a sound barrier and can also protect against corrosion and damage from road debris.

Tesla’s Own Pursuit of Quiet

Tesla themselves have also been striving towards a quieter ride for their customers. In 2020, the manufacturer introduced a factory-installed "double pane" window on the Model 3, designed to reduce wind noise.

Tesla has also been developing their own "quiet tire." Reportedly, these tires are designed to have lower rolling resistance and less noise than conventional tires, although they are yet to be released to the public.

From door seals and trunk kits to DIY solutions and tire choices, there are numerous ways to insulate and soundproof the cabin of a Tesla Model 3. Each has its own merits and should be considered based on your specific needs and expectations. Remember, a quiet cabin can greatly enhance your overall driving experience, making each journey as enjoyable and peaceful as possible.

Advanced Sound Deadening Kits for Tesla Model 3

Advanced sound deadening kits are becoming increasingly popular among Tesla Model 3 owners seeking to enhance their vehicle’s soundproofing. These kits are designed to reduce road, wind, and vehicle noise, creating a quiet and serene driving environment.

A sound deadening kit typically includes materials such as damping mats, mass-loaded vinyl sheets, and closed-cell foam. The damping mats are applied directly to the car’s metal surfaces, helping to dampen vibrations and reduce resonance. They can be installed on the interior of the car’s doors, roof, and floor, as well as in the trunk.

The mass-loaded vinyl sheets are often placed over the damping mats to add an additional layer of soundproofing. This heavy, thin material is highly efficient at blocking sound waves and can be used throughout the vehicle.

The closed-cell foam is used to absorb airborne noise and is particularly effective at reducing higher-frequency sounds. It can be installed beneath the cabin’s carpeting or under the seats.

Many sound deadening kits also include adhesive tapes and sealants to ensure a secure installation. These kits can be installed by a professional or can be a DIY project for those who are handy.

Moreover, for Tesla Model 3 owners who are more concerned about wind noise, they can opt for a wind guard. These accessories, usually made of carbon fiber, are designed to deflect wind away from the vehicle, reducing the level of wind noise inside the cabin.


The Tesla Model 3 is a marvel of modern engineering, but like all vehicles, it’s not without its flaws. Noise inside the cabin can be a concern for Model 3 owners, particularly when driving at high speeds or on rough road surfaces. However, numerous solutions can help reduce this noise, including door seals, trunk kits, and interior accessories, as well as different wheel and tire choices.

Additionally, advanced sound deadening kits and wind guards offer further options for those seeking to create a quieter driving environment. The choice of solution largely depends on the specific type of noise you’re looking to reduce and how much time and money you’re willing to invest.

Finally, it’s reassuring to know that Tesla themselves are also working towards reducing cabin noise, with innovations such as double pane windows and the development of their own "quiet tire". This continual improvement is one of the many reasons why Tesla remains a leader in the electric car market.

Investing in noise reduction for your Tesla Model 3 not only makes each journey more enjoyable and peaceful but can also enhance the overall value and appeal of your vehicle. Whether you choose a DIY approach or opt for professional installation, remember that every effort made to reduce noise contributes to a more comfortable and luxurious driving experience.
