The ‘Whisper Strategy’ is Ford’s quest to create quieter cars

Where once drivers had to shout to make themselves heard above certain speeds, modern day cars are comparative oases of calm where conversations and music are clearly audible, even at low volumes.

Ford’s ‘Whisper Strategy’ delivers lots of small noise improvements around the vehicle that add up to a big difference, helping make journeys more comfortable and less tiring for drivers and passengers.

The sound of silence

For the new Kuga, Ford examined noise‑generating elements from the suspension to the door seals to help find ways to optimise interior refinement.

Adding perforations to Kuga Vignale leather seat bolsters reduced the total area of flat surfaces inside the cabin, helping absorb rather than reflect noise.

Aerodynamically-tuned sound shields are added underneath the body of the vehicle that help limit road and wind noise entering from outside.

Ford engineers spent two years testing more than 70 different tyres over surfaces from smooth Tarmac to rough concrete and cobbles, in wet and dry conditions and at a range of speeds to find the exact specification that kept road noise to a minimum while still delivering high levels of comfort and grip.

Channels behind the exterior panels that allow hidden wiring and components to pass from one area to another are smaller and narrower to limit airflow inside the body.

Refined quality

The ability to drive without a petrol or diesel engine enables quieter journeys. The plug-In Hybrid combines a petrol engine, electric motor and generator, and 14.4 kWh lithium-ion battery for zero-emission pure-electric driving capability.

Using the EV Now selectable drive mode switches off the petrol engine and powers the vehicle using battery and electric motor alone, achieving interior road noise levels of just 52 dB(A) in controlled tests – equivalent to gentle rainfall.

It also features Active Noise Cancellation technology. The system works just like popular noise-cancelling headphones – detecting unwanted low-frequency cabin sounds through strategically-placed microphones and counteracting them with an opposing soundwave from the B&O Sound System.

Telling sounds

A test carried out by Ford showed that occupants in the Kuga, experience interior noise levels that are just one quarter of those experienced by their grandparents in a 1966 Ford Anglia.

Below is comparative test, conducted in 3rd gear at a speed of 50km/h:
