It will have reduced weight for improved mobility and transportability,
delivering the same tactical range as the M1A2 Abrams but with 50% less fuel consumption.
That is significant as one of the long-standing complaints about the Abrams has been its huge fuel usage.
In fact, the Abrams X seems to be dumping the famous gas turbine
that has always powered the type for a new hybrid power pack.
This will almost certainly combine the US Army’s new diesel Cummins Advanced Combat Engine
with some form of electric drive.
This would allow for the APU to be dispensed with as assumedly the battery systems
on the new drive train will power the tank when the diesel engine is shut off
The Cummins ACE is an intriguing system that offers flexible layout options
which means the engine can be configured with 3, 4 or 6 cylinder arrangements to deliver power ranges from 750 to 1,500 horsepower.
It is also expressly designed for integration into hybrid drive systems.
