Kia KM250
The KM250, alternately K511, is a family of 6x6 tactical truck manufactured by Kia Motors in South Korea. It is an updated version of the US-made M35A2 cargo truck. While retaining the classic American look of long bonnet, soft-topped cab and a large carrying area, KIA has integrated the truck with several modern features. History
The KM250 is developed on the basis of the classic American truck M35A2, which was manufactured under license. In April 2020, a $1.4 billion deal was signed for a total of 10,000 new trucks. These vehicles are set to replace the Republic of Korea Army's (RoKA's) in-service K511 (KM250) and K71 (KM500) vehicles which have been in service with the RoKA and a few other countries for more than 40 years. In particular, the KM250 will be replaced by a truck with a hoodless cab and the possibility of installing additional reservations. Description
The KM250 is powered by the 180 hp KK-7.4 diesel engine. The truck is capable of cruising at 95 km/h with torque generation recorded to as much as 490Nm. Weighing 6.1 tonnes, the truck, designed with 6x6 configuration, is equipped with a fuel tank, with a capacity of 200 litres of fuel. The 200-litre tank capacity replaces the payload limitation by enabling the vehicle to reach a destination as far as 955 km. It has a payload capacity of 2,270 kg off-road and 4,550 kg on hard surface roads. The vehicle can accommodate up to 22 passengers including 20 fully equipped troops and a crew of two. It is equipped with a pintle hook for towing heavy cargo trailers and 105 millimeter howitzers. It can exert a maximum braking force by utilizing the air over hydraulic technology. The removable slated body walls serve as troop seats when folded down. The canvas top and supporting structure can be removed from both the cab and cargo body. The windshield can be also folded for maximum versatility. A front-mounted winch was optional. G.A.T.O.R
