These are current projects running in DRDO lab CVRDE. All these projects are planned to be completed by 2030.
Small typo on the poster. It should be "600/800 hp transmission" not "600/8000 hp transmission". That transmission is obviously meant to be coupled with this engine:
Ashok Leyland's Neptune series of turbodiesel engines today go up to ~400 hp. The 600/800 hp engine would be the natural step for AL.
So many projects with L&T as the principal contractor. With the K9 Vajra & the Zorawar projects at hand, L&T can emerge as they primary producer of light/medium tracked vehicles in India. A few years back you would think TATA motors would be in this position not L&T.
Medium to Heavy tracked vehicles would probably remain the domain of BEML/CVRDE. Maybe the NG-MBT project would change that.
Nice. This could actually be the Arjun variant as it says "T configuration powerpack" (longitudinal engine, transversal transmission) and then there's the CV1500"A".
It would seem that the original CV1500 is a U config (transversal engine, transversal transmission) meant for the NGMBT, going by that recent flyer/brochure for the 1500 hp transmission.

Development of 600 hp Engine
To meet the requirements of Futuristic Infantry Combat Vehicle, CVRDE took up clean-sheet development of a compact High Power engine.
This engine has been completely Designed & Developed Indigenously
Specification
• Type : V90, 8 Cylinder, Turbocharged, Charge cooled, Direct Injection
• Rated Power : 600 hp
• Rated Speed : 3000 rpm
• Peak Torque : 1505 Nm
• Bore : 114 mm
• Stroke : 112 mm
• Swept Volume 9.15 litres
• Highest Specific Power among all AFV engines in India (65 hp / liter)
Milestones Achieved
• Designed In-House by CVRDE
• Design Vetted by M/S ARAI, Pune
• Gen 1 Engines Manufactured by M/S Ashok Leyland Chennai
• Engine Calibration & Tuning for full performance completed by CVRDE
• Demonstrated Targeted Engine Power and Torque
• Completed 100+ hours of Test
Salient features
• High Speed CRDi FIE with waste gated turbochargers
• Unit Cylinder Head
• Better High Altitude performance
• Designed to suit Desert conditions
• Designed to suit Indian manufacturing facilities
• Compact & Light weight
• The engine will find applications in FICV, AAP, WhAP vehicle projects

This is the engine that is being developed with Ashok Leyland, started 5 years ago. With the introduction of the light tank, they also began working on an 800hp version.
I said unknown Origin in the sense that I don't know the origin of the Brochure itself not that I am unaware of the fact that CVRDE is developing an engine
Maybe you could edit my post to brush up this grammatical mistake
Yeah way back in 2023 December CVRDE job work listed the engine related work, given it takes 12-24 months work each project it matches with the suggested timeline for completion. Hopefully all are in good shape. Whether the end product is accepted by the user or rejected, we can not tell.
ps: DRDO site is down , why did they release a new site where the url does not work?

Thank you. By the way if it wasn't known before then the 800 hp engine is called CV510E 00 0005 and A&L is the DcPP (for the transmission it should be L&T iirc).
