Germany did not convey, its the company who did? Issue would have come had the German Govt denied export license. But this is a company's decision. The powerpack related work which is probably handled by CVRDE, terms had the 1400hp MTU engines related work alongside in the schedule for assistance in the 1500hp powerpack development work. I guess priority is now shifting. below estimate in the job ad from December 2023.

I would have shelved the MTU engines plan myself, but perhaps there are certain issues, like need to redesign some LRU or similar major/minor niggles.

Defence Secretary Shri Giridhar Aramane presided over the maiden test-firing of India’s first indigenously-made 1500 Horsepower (HP) engine for Main Battle Tanks at BEML’s Engine division in Mysuru complex on March 20, 2024. The achievement heralds a new era in the country’s defence capabilities, showcasing the technological prowess and commitment to self-reliance in defence technologies.

The 1500 HP engine represents a paradigm shift in military propulsion systems, possessing cutting-edge features such as high power-to-weight ratio, operability in extreme conditions including high altitudes, sub-zero temperatures, and desert environments. Equipped with advanced technologies, the engine stands on par with the most advanced engines globally.

Inaugurating the Test Cell, the Defence Secretary described the achievement as a transformative moment which will enhance the capabilities of the Armed Forces. CMD of BEML Shri Shantanu Roy stated that the accomplishment solidifies BEML's position as a key contributor to defence production in the country, underscoring its commitment to serving the nation's needs in this critical sector.

The first test-firing of the 1500 HP engine signifies the completion of Generation One, focusing on technology stabilisation.

Generation Two will see BEML producing engines for various trials at Combat Vehicles Research and Development Establishment, a DRDO laboratory, and their integration into actual vehicles for user testing.


The project is slated for completion by mid-2025. The project, initiated in August 2020, has been meticulously structured into five major milestones, ensuring timely completion and adherence to quality standards.

The Defence Secretary also inaugurated the ‘Wall of Fame’ to recognise the extraordinary efforts of the BEML team. It symbolises their contribution towards advancing the defence capabilities of the country and achieving milestones in indigenous technological innovation. Senior civil and military officers of the Ministry of Defence; industry partners and officials of BEML Ltd were present on the occasion.

Development of 600 HP Engine under Self Reliant India (Atmanirbhar Bharat)

Posted On: 15 DEC 2021 10:48PM by PIB Chennai

Combat Vehicles Research & Development Establishment (CVRDE), a premier establishment of DRDO is involved in the design and development of Battle tanks for Indian Army. CVRDE has taken initiative to develop indigenous engine to power futuristic combat vehicles. In this regard CVRDE designed 600 hp engine ab-initio, which is compact, efficient, light weight due to incorporation of advanced technologies. The engine is comparable to contemporary battle tank engines. M/s Ashok Leyland, Chennai, a leading automotive industry is identified as Development cum Production Partner by CVRDE for manufacturing of 600 hp engine. M/s.c Ashok Leyland had applied modern & innovative methods and completed manufacturing of engine in a record time despite total lockdown due to COVID-19.

Shri Pravin K Mehta, Distinguished Scientist and Director General (ACE), inaugurated the testing of CVRDE-DRDO Developed 600 hp engine in the presence of Shri V. Balamurugan Director, CVRDE, other directors of DRDO ACE cluster and Dr. N Saravanan, CTO, Shri R Rajesh, Head- Defence & Shri Krishnan sadagopan, Head-Engine Development of Ashok Leyland on 15th Dec 2021 at Engine Development Centre, Ashok Leyland, Vellivoyalchavadi, Chennai. This inauguration also marks a major milestone in iconic week under Azadi Ka Amrut Mahotsav.

Successful induction of 600 hp engine in Indian Army through the indigenous efforts of DRDO and Indian industry will result in development of series of engines for other battle tanks.This will lead to self-reliance in Tank Engine technology, which in turn result in plethora of advantages viz., Spin off technology for other applications, savings in FE, export of tank engines and generation of employment in Indian industry. according to the press release issued by CVRDE.

We already have copied and uprated the V46 to 1000hp right?
Yes. That engine was meant for the T-72 CIA variant. Kunal Biswas took a video of this engine:



The V46-6 engine in the video looks nothing like the engine shown in the photos above. I've looked at BMP engines, T-90's engines etc., the engine shown in the photo doesn't look like anything Engine factory Avadi makes.

So, is this actually their own design? PSUs are doing serious R&D work? Difficult to believe.

When that uprated V46-6 engine was showcased, it was mentioned this new uprated engine will be mated with the same old transmission. That transmission works fine in forward gear but not so much in reverse. We have seen that same issue in the Russia-Ukraine conflict.

I figured since they uprated the engine they might as well make a new transmission. Have they actually made a new engine?

The uprated V46-6 retains the connected cylinder head usually seen on Soviet/Russian diesel engines. While this engine has a segmented cylinder head reminiscent of the CVRDE's 700 hp engine:

This is also a V8 engine unlike the MTU, which also has segmented cylinder heads, but is a V10 engine. Could this be an uprated variant of the CVRDE's 700 hp engine that Engine factory Avadi is prototyping & testing?

It makes sense for CVRDE to develop this. They are developing a 600-700 hp engine for AFV/IFV & light tanks etc. They are also developing a 1500 hp engine for main battle tanks. If they can make a 1000 hp engine for medium tanks (like T-72) their portfolio is complete.
