Quietest cars
40 cars with least interior noise at 100 kph. Updated October 2025.
Quietness, refinement and insulation from outside environment - those are some of the qualities that make experience of driving luxury cars different from mere "regular" economy cars.
Noise measurements are part of standard testing protocol for many well known car magazines. This list shows cars with lowest noise reading at 100 kph (62 mph).
Unsurprisingly, most cars listed here are German luxury brands - Mercedes, BMW, Audi. Electric cars also have slight advantage as they produce almost zero engine and drivetrain noise. However, at highway speeds vast majority of overall noise comes from wind and tyres.
