The huge heart pump out the power 780 hp at 7,100 rpm and the torque of 960 N⋅m at 4,000 rpm. The most crazy part of this Lebanese powerhouse is that it’s the first car to have headlights with embedded jewels that contain titanium LED blades with 440 diamonds in it .Although the vehicle's headlights at purchase based on the colour choice. The car also uses a holographic display system on the center console with interactive motion features, as well as gold stitching on the seats. The Abu Dhabi Police car is included in the total of seven, meaning only six were available for purchase by customers. W Motors has since confirmed all cars were sold.
