Writes about this
The Defense Express article states thatInitially, the T-90's shortcomings became apparent in India, when local T-90S "faced critical problems, primarily engine overheating and rapid engine failure." At the same time, as journalists write, Russian tanks still use virtually the same engine design.
Problems with the engine supposedly did not escape the T-90M "Breakthrough". Because of this, the tank in its specific power is inferior to almost all competitors.
