S90s

S90s is a designation used to refer to multiple product lines that use the model name S90 across different industries. The most prominent uses are the Volvo S90, a mid-size luxury sedan, and the Yamaha S90 family of digital synthesizers.

The Volvo S90 is a mid-size luxury sedan produced by Swedish automaker Volvo Cars. Introduced in 2016 as the successor to the S80, it sits at the top of Volvo's 90-series lineup and is built on the scalable SPA platform. Drivetrains offered include conventional petrol engines and plug-in hybrid options, with all-wheel drive available on several trims. The S90 is known for its minimalist interior, emphasis on safety technologies, and a suite of driver assistance features. It has undergone updates and facelifts over its production run and is sold in multiple global markets.

The Yamaha S90 is a line of 88-key digital synthesizers made by Yamaha. The S90 family includes variants such as the S90, S90ES, and S90XS. These instruments are valued for their weighted-action keyboards, multi-voice performances, and built-in sound sets suitable for live performance and recording. They typically include a selection of acoustic and electronic voices, performance modes for layering and splitting timbres, and connectivity for MIDI and external devices. Specifications vary by model and generation.

In addition to these, the S90 designation may appear in other product contexts, but the Volvo S90 and Yamaha S90 lines are the most widely referenced in public documentation.
