The BTR-4 is a more flexible design than the older BTR-60/70/80s as the changed layout makes it easier to adapt the vehicle to specialized roles.
The layout of the BTR-4 represent a change compared to the older BTR-60/70/80 designed in the Soviet Union. The vehicle has a conventional layout similar to western designs like the German TPz Fuchs with the driver's and commander's compartment at the front part of the hull, the engine and transmission compartment in the middle, and the troop compartment at the rear. The troops enter and leave the vehicle either through the rear doors or the roof hatches, and the driver and the commander are provided with doors located on the sides of the hull.
The vehicle can be armed according to customer requirements. The prototype is armed with the locally designed New Armament Module which is armed with one 30mm automatic cannon, 7.62mm coaxial machine-gun, up to four 9P135M Konkurs or Baryer Anti-tank missiles (two on each side of the turret), and one 30mm automatic grenade launcher (fitted in place of the AT missiles on one left-hand side of the turret). It can also be fitted with different turret weapons modules: the GROM module, SHKVAL module, and the BAU 23x2 module. There are also different designed versions such as the BRM-4K Reconnaissance vehicle, BTR-4K Command vehicle, BTR-4KSh command and staff vehicle, MOP-4K Fire support vehicle, BREM-4K repair and recovery vehicle, and the BSEM-4K recovery and medical vehicle.
The BTR-4 has a maximum speed of 110 km/h and can cross water obstacles at a speed of 10 km/h. The vehicle is powered by a 3TD diesel engine with 500 hp.
