How smartphones are steering the future of in-car audio

A New Era for Automotive Listening

In-car audio is changing fast. For decades, the experience was defined by radios and CD players. Today, the smartphone has taken control. Our latest bulletin, Automotive Perspectives, shows that more than half of drivers across major markets now rely on their phones as the primary source of audio. This shift creates a new demand, with drivers expecting their cars to deliver the same seamless audio experience they enjoy everywhere else.

The Smartphone First Cabin

Research spanning over ten thousand respondents confirms this behaviour is universal. Whether through Bluetooth or smartphone mirroring systems, 51.5% of drivers connect their phone for listening. For younger drivers, the car is simply an extension of their personal device. They expect instant playback and consistent sound without any friction. Older generations are not far behind, though they often place a higher value on simplicity and physical controls.

This divide highlights a central requirement. The technology must feel invisible. Audio should resume exactly where it left off, and the transition from headphones to car speakers needs to be effortless. With the vast majority of new vehicles expected to support this mirroring by 2026, automakers and audio brands must perfect experiences that feel both instant and predictable.

Radio’s Enduring Role

Despite the smartphone’s dominance, traditional radio remains the second most used source, preferred by over a quarter of drivers. When immediacy matters, such as for traffic updates or breaking news, radio still wins. It is the ultimate one-touch medium, offering reliability and familiarity with minimal effort.
Its strength lies in that simplicity. To stay relevant, radio must preserve instant access. This means one-press entry, effective buffering for patchy reception, and ensuring voice commands work flawlessly. Treated as a trusted context anchor rather than a legacy feature, radio will remain a vital companion in the connected car.
Beyond Music: The Rise of Spoken Word

Music still dominates in-car streaming, but spoken word formats are accelerating. Podcasts and audiobooks together now account for nearly a third of streaming time in some markets. In the USA and UK, podcasts are mainstream, while audiobooks have a strong following. In China, spoken word content is rising alongside the growth of native streaming platforms.

This trend has direct implications for vehicle design. Cabins tuned only for bass-heavy music will underperform for dialogue clarity. Audio systems need a clear mid-range presence for voices and intelligent processing to keep speech intelligible over road noise. User interfaces must also adapt, with voice commands that make accessing podcasts or audiobooks simple and intuitive.

What Drivers Want Next

When considering their next car, drivers consistently prioritise sound quality above all else. This is followed by effective noise reduction and reliable voice control. While immersive formats like Dolby Atmos are gaining awareness, clarity and everyday convenience remain the dominant concerns for most. Regional nuances exist, with features like immersive audio performing particularly well in China thanks to strong local content partnerships.

These consumer priorities align perfectly with the industry’s move towards software-led upgrades. Features such as enhanced clarity, advanced noise cancellation, and personalised sound profiles can all be delivered as upgradeable experiences post-purchase. Offering trials of these features allows drivers to personally experience the difference, creating a compelling path to new revenue.

The Road Ahead

In-car audio continues to evolve at a remarkable pace. Over the coming model cycles, the technical distinction between a tethered smartphone and a native infotainment system will matter less than a single, simple guarantee. Whatever the driver was listening to before starting the car must continue instantly, clearly, and without complication. Brands that consistently keep that promise will own the soundtrack to the journey.
The competitive edge now lies entirely in the removal of friction. Fast connections, seamless volume transitions, and accurate voice commands define a premium experience. Software-defined audio architecture allows these premium features to be delivered on standard hardware, opening the door to ongoing customer engagement and new commercial models.
