by The production of the ZMZ-523 engine has been resumed in the Russian Federation. It was developed in the early 60s. This is reported by Focus.
This V8 is a slightly improved modification of the ZMZ-53 engine, which was produced at the Zavolzhsky Motor Plant since 1963. Around 6.5 million of these engines were assembled in total.
The gasoline engine ZMZ-523 was installed on PAZ-3205 buses and GAZ-3308 trucks. It was discontinued in 2021 due to being outdated and unpopular, but in the conditions of sanctions, it became needed again. The issue is that the shortage of imported components does not allow the production of more modern power units. ZMZ-523 will be available for both new vehicles and the secondary market.
The ZMZ-523 has a simple underslung construction, and the main difference from the archaic ZMZ-53 is the replacement of the carburetor with fuel injection. With a working volume of 4.7 liters, it develops only 124 hp and 298 N∙m. Nonetheless, representatives of the Zavolzhsky Motor Plant claim that the V8 “has good dynamic characteristics in relation to commercial transport”.
For its parameters, the engine is characterized by increased fuel consumption — 22-30 L/100 km. The more economical ZMZ-524 version with factory LPG will also return to production: its output is 138 hp and 314 N∙m.
