Developed from the GAZ-69, UAZ-471 and UAZ-460,^[4] the UAZ-469 was introduced in 1971 to replace the GAZ-69. It is powered by the same 75 hp (55 kW) 2,445 cc (149.2 cu in) UMZ-452MI inline-four engine as the UAZ-452 and is able to run on gasoline with an octane rating as low as 72 (although 76 was preferred).^[5] The UAZ-469 presented two great advantages: it was able to drive in virtually any terrain and it was very easy to repair. The vehicle was originally not available for purchase by the public, but many were sold as surplus to private owners.^[3]
