Even as CVRDE develops this technological capacity, it is looking further ahead at a hybrid engine for the FMBT after 2030. Sivakumar says that a tank remains static for at least 40 per cent of the time in battle, during which time its engine idles. "This means that 40 per cent of the time, you wastefully run a 1,500 Hp engine, guzzling diesel and giving away the tank's position, while you need very little power for running electricals like the radios and gun control equipment or for moving the tank slowly. So, we are evolving a hybrid technology concept in which the tank will have two engines: a 500 Hp engine for low power mode and another 1,000 Hp engine that kicks in when high power is required, e.g. for manoeuvring in battle," explains the CVRDE director.
