The chassis is started as a simple redesign of the TAM-150 truck but evolved to include a completely modified hull, 4×4 and 8×8 configuration, added armor and dozens of structural improvements.

The V-shaped hull and special drive train construction affords excellent mobility in mud pit situations, over deep trenches, icy and slippery surfaces as well as inclines smaller than 50 degrees.

The 440 HP engine provides good acceleration but low speed over treacherous terrain, a standardized mechanical transmission allows for direct control.

The thing which stands out about the Lazar is the open side system which allows troops inside to use their own personal weapons (40 mm grenade launchers, assault rifles etc.)

There is an internal space which can be used for transportation of MANPAD systems, larger machine gun setups, all types of food, ammunition, and other cargo.
