How is the sound insulation in the Volkswagen Passat on highways? Is it really as quiet as people say?

Its sound insulation is one of the best things I noticed. Even the engine noise isn’t noticeable inside the cabin—unless you’re really flooring the gas.

Honestly, the Passat’s sound insulation is excellent compared to other cars in the same category. At 120-140 km/h, wind and outside noise are minimal, making it very comfortable for long trips.
