As we know, Italian Army planning to the upgrading its MBT Ariete (we already wrote about this program, link - იტალიური Ariete-ს მოდერნიზაციის პროგრამა). Below is the some very interesting details about new engine of Ariete MBT.
Sorry about direct translation, but this is what we have:
Focus on the CIO (Consorzio Iveco Leonardo) update program on the Aries AMV (Ammodernamento di Mezza Vita of the Ariete - Mid Life Update) for the EI. As mentioned, the program is well underway, with the work areas well outlined and set up, with the delivery of the prototypes expected in the course of 2021. At present there are various info (1)
as regards above all the powertrain, which for obvious reasons (due to timing and thousands H of bench tests), is not a new concept, but is a complete re-engineering of the current V12 MTCA (Modular Turbocharger Aftercooler), in fact (2)
during the renovation, #IVECO is implementing substantial changes to the original engine block in V12 architecture; among the many works in progress are: - the replacement of the mechanical feed pump with an electronically controlled Commonrail type (3)
- the displacement will be increased from the current 26L to 30L by changing cylinders, pistons and crankshaft, increasing the stroke of the cylinders. It should be mentioned that most of the new mechanical components come from the turbo Vector V8 of the new Centauro 2. (4)
With the adoption of the new mechanical components and the complete reconstruction of the powertrains, we go from the current 1250hp (1270 in emergency situations through overboost) to 1500hp, such as to guarantee a pot / weight ratio of 24hp / t with all the protection kits installed 4
(PSO Peace Support and War); i and 25 hp / t with the War kit only. The modified engine has the designation "V12AMV". Given the increase in engine torque, improvements were also made to the IVECO automatic gearbox (license #ZF) (5)
In fact, the German company has already studied the modifications necessary to receive the greater torque in entry and its distribution. New gearboxes are already planned by ZF through a specific kit. It should be noted that the updated engine will offer a value (6)
Almost three times higher torque at low rpm, which will make the undercarriage much more responsive even in the execution of the "pivot" maneuver. - Completely redesigned the braking system and its subsystems through the use of advanced components (7).
As a result of the increase in weight and the greater drive torque, 20% wider tracks are also provided to offer the undercarriage a lower footprint and will allow it to more easily overcome soft ground. (8)
PS: My next Aries focus will be on the tower and all the new electronic systems that are being implemented on the chariots.

🇮🇹Focus sul programma di aggiornamento del #CIO sull'#Ariete AMV per l'EI. Come detto, il programma si trova ben avviato, con le aree di lavoro ben schematizzate ed impostate, con la consegna dei prototipi prevista nel corso del 2021. Allo stato attuale si hanno diverse info (1) pic.twitter.com/FVkRwiM0zo
