The massive 12,000 pound bio-fuel Knight XV is fully armored, completely impenetrable, and fun for the whole family.

The eco-conscious drug dealer in your family will be happy to know that the Knight XV is available for purchase at the famous Barrett-Jackson Collector Car Event, being held this week in Scottsdale, Arizona. Called the "most secure, luxurious" SUV in the world, the XV is completely covered in armor outside, comfortably seats six inside, and runs on biofuel.

Specialty armored-SUV maker Conquest Vehicles used ballistic hardened steel and ballistic fiberglass fenders and bumpers to make the Knight XV as impenetrable as possible. Windows and windscreens are made from a bulletproof 2.5-inch (64mm) thick transparent material. Armor can be added or subtracted depending on the customer's need.

Drawing inspiration from the Gurkha military vehicle used by the U.S. Army, the Knight XV is aimed more towards the private sector. The Gurkha, made by Florida company Armet Armored Vehicles, is also used by the Russian Foreign Ministry and various SWAT teams. It is based on a Ford F550 chassis.

Conquest president William Maizlin said, "Since launching the KNIGHT XV at SEMA to the auto industry in November, the demand by auto enthusiasts and media to see and experience this vehicle has been so positively overwhelming that we decided to feature it at Barrett-Jackson so the public could see it in person for the very first time."

Although built to run on bio-fuel, Maizlin says the car can also run on petrol or diesel. The Knight uses a 6.8-liter V10 getting 400 hp and 498 ft-lb of torque. Like its inspiration, it is also built on a "super duty Ford modified platform chassis." It is a massive vehicle, at 240-inches long, 98-inches wide, and 100-inches tall. The Knight XV has a 14" ground clearence, 141" wheelbase, and weighs in at 12,000 pounds (5,443 kg). Custom designed, 20-inch forged aluminum wheels are wrapped in Mickey Thompson Baja Radial ATZ ballistic run-flat tires.

Inside the Knight you will find six individual six-way powered leather seats, Wilton Wool carpeting, and a sunroof. Each seat gets its own side-mounted lap top tray. Entertaining your passengers is easy, thanks to the Alpine entertainment unit, LCD monitors, and a Playstation 3. LED ambient lighting, and a night-vision capable rear camera are also included. There is plenty of room for everybody in this 283-cubic-foot cabin.

At a paltry $310,000, how can you not afford to protect your family with the Knight XV? Only 100 will be produced in its first run, each being handbuilt.
