The upcoming Volvo V90 wagon has been revealed via leaked scale models, which have been published online ahead of the car's debut.

These images were originally published by Chinese website AutoHome, and show scale models of what looks like a production version of the upcoming V90 wagon.

This follows on from a similar leak earlier this year for the yet-to-be-revealed S90 sedan.

The V90 is based on the Scalable Product Architecture that has so far spawned the XC90 SUV. Next year, Volvo will begin sales of a new range-topping sedan, the S90, and a wagon accompaniment, the V90.

In time, the SPA component set will also be used underneath the next-generation S60, V60 and XC60.

Under the bonnet, the S90 and V90 will likely use the same suite of drivetrains powering the XC90, including turbocharged, and turbocharged and supercharged four-cylinder petrol engines, turbocharged four-cylinder diesels, and a plug-in hybrid.

Stylistically, the new V90, if this model proves to be accurate, is essentially a production-ready version of the 2014's Concept Estate, albeit with an extra set of doors, the addition of working door handles and minus the concept's frameless windows.
