Notes:

The appearance of Knight XV is very tough and sturdy, giving people the impression that it can break out of a tight siege just by running rampant, like a tank on the road. The body is made of bulletproof steel plates and glass-avant-garde wheel arches and bumpers, and the windows and windshield are made of 64 mm thick bulletproof transparent material.

It can withstand NATO standard hard steel nuclear bullets with a firing rate of 820 meters per second and a caliber of 7.62x51 mm. It can withstand attacks with 15 kilograms of TNT explosives. The vehicle chassis can also withstand grenade explosions. The car can run not only on traditional fuels such as gasoline or diesel, but also on biofuels.
