From the early sketch stage through to clay modelling and its Paris debut, the clip offers an insight into how Porsche's Weissach R&D team does what it does.
Porsche has yet to say if the Sport Turismo will make the leap to market, but the German icon is known for sticking to production-focused concepts.
In concept form, the Sport Turismo's cabin is gifted with a spartan layout, ditching the usual switches and dials for a large LCD touchscreen display. This, too, will likely make way for a more conventional unit in production form.
Power in the Panamera Sport Turismo concept is provided by a plug-in hybrid arrangement, matching a supercharged 3.0 litre V6 with an electric motor.
The system is an evolution of the package already offered in the current Panamera S Hybrid and Cayenne S Hybrid models.
Here, the electric motor produces 70kW - around twice the powered offered in the current system - supplementing the 250kW generated by the big super-six.
Porsche says the combined powerplant will grant a 0-100km/h time below six seconds, and an all-electric driving mode will deliver a range of around 30 kilometres.
