BTR-60

The two-engines setup has an advantage in the fact that each engine could work without the other. This means that, if one engine is disabled, it doesn't affect the other one and the vehicle can still move, albeit with reduced speed. This setup, however, caused several problems that either do not exist in single-engined vehicles or weren't as serious: the design itself was complicated and the amount of work that had to be done during exploitation and repair was higher than in vehicles with a single engine. The engines themselves were originally intended for truck use, which meant that they were working in extreme conditions not originally envisioned for them. Because of this, engine breakdowns were frequent. The vehicle also used large amounts of fuel and caught fire easily. Despite all this, the two-engines setup was used in all BTR-60 production models as well as most variants of the BTR-70. The single-engine setup was introduced in the BTR-80.
