NefAZ (Neftekamsk Automobile)(НЕФАЗ) is a Russian manufacturer of trucks, buses, farm equipment and combine harvesters. They are the largest automotive manufacturer utilizing the Kamaz chassis. Founded in 1977 in Neftekamsk, Republic of Bashkortostan, Russia, NefAZ first assembled Kamaz trucks. Buses were added in 2000, and combine harvesters in 2009.
KAMAZ (KAMA3) owns about 50% of NefAZ. Some of the buses are licensed from VDL Groep and carry the VDL-NefAZ brand., while others use Daimler-NefAZ or NefAZ as the branding. Trucks are built using both the NefAZ and Kamaz brand.
Combine harvesters were added to the mix in 2009 with a tie-up with AGCO and the Challenger brand, with NefAZ assembling CKD (Completely Knocked Down) harvesters from the Italian Laverda harvester plant. In future phases, more of the parts will be sourced locally, until instead of using CKDs, NefAZ is building the complete harvesters, and building their own CKDs to send elsewhere for assembly. The harvesters are built in both the Cat-yellow and a red livery, and carry the name AGCO-NEFAZ Challenger on the side.
