-This is my understanding, I could be wrong- The problem is that the domestic transmission produced by Ford Otosan for the Ekotorq engine has a 600 HP retarder. The domestic Ecotorq transmission cannot keep up with the engine's increased power of 720 HP.
This could be a reason, I don't really know much of detailed specifics of how engine/transmission combination works.
-Again, this is my understanding, I could be wrong again- this transmission is designed for comfort in civilian use. It is too complex for military use, it has 16 forward and 4 reverse gears.
I doubt that one though, nearly every 8x8/6x6 tactical wheeled vehicle uses civilian/industrial grade engines, Ecotorq has been used on heavy duty trucks for years.
Another possible reason why the domestic transmission was not preferred in the Arma II military vehicle may be that some critical components of the transmission are of foreign origin.
Eh, that is incredibly weak reason and if such reason actually put up using against Ecotorq I don't know what to say. Pars running on foreign power pack, if we have proven piece we should take advantage. Of course it is easy for me/us to talk from here we don't really know tests and actual requirements of Command.
Also I could find only one component used in Ecotorq Transmission is foreign origin which is Retarder. In Voith's website it is stated that Voith will be supplying retarders for Otosan's new 16-Speed Transmission, this news is dating back to 2021,

There's nothing to suggest that Arma II runs in the YNHZA program, unlike FNSS Alpha. FNSS directly confirmed that Alpha/Pars V was not a new design and that it had been running for more than 3 years and joined all the tests.
I'm actually glad Command actually went with a competent design, Alpha looks like an incredible platform. I hope it will be backbone of Wheeled Vehicles.
BMC Power has 400 HP and 600 HP diesel engines, but BMC Poweer has not developed a domestic transmission for them. There are also 1000 HP UTKU and 1500 HP BATU engines and their transmissions.
As far as I'm concerned TUNA is the only engine in production, 600hp AZRA still not being produced nor used by BMC as Altuğ runs on foreign engine. I hope SSM will pick optimised Ecotorq for 500-800hp class so BMC can actually focus on UTKU and BATU.
UTKU and BATU would solve so many problems we are facing right now, Tulpar with UTKU would be marvellous tracked vehicle for our armed forces, I don't think I need to stress how much we need BATU.
