Spy photographers snapped this very dirty test car at a fuel station. Details on the rear fascia, side sills, and fender trim look identical to the current model. But we do see clear differences at the front, notably with a larger grille and smaller headlights.
It’s believed to have a twin-turbocharged 5.2-liter 12-pot engine. The car could be a standalone fuel burner or a hybrid, and a V8 is certainly a possibility.
