Mercedes-AMG has released an unusual promotional video for a yet-to-be-unveiled model - a battery-powered supercar expected to be based on the GT XX concept.

The video stars Mercedes-AMG Petronas Formula One driver George Russell, with a cameo appearance by renowned actor Brad Pitt. The video appears to be the company's way of hyping up fans for the imminent debut of this unusual new model.
