Ural-4320 is a famous Soviet-design off-road 6 × 6 general utility truck, produced in large quantities since 1977 by the Ural Automobile Plant in Miass (Russia). It was designed for transportation of goods, people, and trailers on all types of roads. Ural has significant advantages in comparison with its competitors, as it can easily overcome the wetlands, fords up to 1.5 m, ditches up to 2 m and climbs up to 60 ‰. But its main role as well as its predecessor's Ural 375D is to serve military objectives.
In 1978 the first commercial batch of vehicles of the basic model "Ural-4320" has been produced powered by four-stroke 210-horsepower diesel engine of "740"model, delivered by KamAZ. The choice of this engine has significantly improved traction, speed and economic characteristics of the vehicle: maximum speed was increased to 85 km/h, fuel consumption was reduced by more than 30%, Maintenance costs reduced by 10.8%. Thus, on the basis of the tried and tested for many years "Ural-375D" the second generation of cars with higher technical and economic indicators has been created.
Since 1992 Ural-4320 is powered by YaMZ-740 10.85-liter V8 diesel engine, developing 210 hp. Later it was fitted with a 220 hp diesel. Current production models are available with more powerful diesel engines. The baseline is the YaMZ-238M2 engine, developing 240 hp. Cab of the Ural-4320 provides seating for the driver and two passengers. An add-on armor kit has been developed for this military truck. It protects the cab end engine compartment from small arms fire and artillery shell splinters.
This truck is still in service with the Russian military as well as many other countries, including Ukraine. Urals are often used by pro-Russian separatists for transportation of troops; Ural 4320 is also used as main chassis for BM-21 Grad.
