Although brands Toyota i Lexus are held in high regard for their reliability, durability and driving comfort, many owners of these vehicles note one rather surprising shortcoming - the insufficient soundproofing of the interior. This problem affects both popular Toyota models and the luxury Lexus line-up. Why does this happen and is it worth investing in additional soundproofing? Let's find out.
Why are Toyota and Lexus less soundproof?
1. Savings in weight and production costs
Today's automotive industry strives for maximum efficiency - lower fuel consumption, lower CO₂ emissions, higher performance. To achieve these goals, manufacturers are striving reduce the weight of vehiclesThis is often at the expense of soundproofing elements. In the case of Toyota and Lexus, this means thinner sound-absorbing mats or none at all in certain areas, such as in the doors, wheel arches or under the floor.
2. Construction priorities
Although Lexus is regarded as a premium brand, even in its priority is given to mechanical comfort and build qualityand not always full sound insulation. Toyota, on the other hand, as a mass-market brand, focuses on reliability and economy - soundproofing takes a back seat here.
3. Global standards, different expectations
In Japan and the US - Toyota's and Lexus' main markets - the road noise standards and customer expectations are different from those in Europe. European drivers often drive at higher speeds (e.g. on motorways), which accentuates the imperfections of the soundproofing.
What is the benefit of additional soundproofing for the car?
1. Acoustic comfort
Less noise from tyres, wind, engine or suspension work means smoother and less tiring driving, especially on longer routes.
2. Higher sense of quality
A soundproofed car gives the impression of being more solid and luxurious. This is often subtle but very clear effect improving the day-to-day vehicle experience.
3. Improved sound quality in the cabin
If you use an audio system - especially in a Lexus - you'll appreciate that when soundproofed, the cabin becomes a a more favourable acoustic environment. The sound is cleaner, deeper, more dynamic.
4. Thermal insulation and corrosion protection
Some soundproofing materials further improve thermal insulation interiors and can protect the bodywork from moisture and corrosion.
What elements are worth soundproofing?
- Doors - reduce noise from the street and improve audio acoustics.
- Floor and wheel arches - reduce rolling noise and stone impact.
- Bonnet and engine bulkhead - dampen the sound of the engine.
- Luggage compartment and rear part of the body - particularly important in hatchbacks and SUVs.
Summary
Toyota and Lexus are brands that are renowned for their reliability and comfort, but they do not always offer ideal cabin soundproofing. Fortunately, this is a shortcoming that can be remedied relatively easily and effectively with additional soundproofing. It is an investment that increases comfort, improves sound quality and makes driving more relaxing. For many drivers - definitely worth it!
