TIV2 weighs in at and is a 4-wheel drive, 3 axle vehicle. It stands taller than the original TIV and is capable of going on mud and unpaved roads without the fear of getting stuck. The original TIV has 2-wheel drive and extremely low ground clearance that would cause it to get stuck on unpaved roads.

The windows in TIV2 are all bullet resistant 1 5/8 inch interlayered polycarbonate sheets and tempered glass. TIV2 also features an IMAX filming turret similar to the one on the original TIV. The original TIV's somewhat cumbersome hydraulic claws were not used on TIV2 in favor of four hydraulic skirts that drop down to deflect wind over the TIV to stabilize it and protect the underside from debris plus two stakes that extend down . The stakes were so effective that after the first use TIV2 could not retract the stakes and they had to be dug out by hand. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sean Casey (filmmaker)」の詳細全文を読む スポンサード リンク
