India Launches Domestic Production of Armored Vehicle Engines, Challenging Reliance on Imports
New Delhi – India is establishing a national capability to independently manufacture engines for its armored vehicles, a feat unseen in France for decades, marking a important step towards self-reliance in defense technology.The initiative, spearheaded by the Defence Research and Development Organisation (DRDO), aims to eliminate dependence on foreign suppliers and bolster India’s defense preparedness.
The first iteration, designated “Gen-1,” has already undergone 250 hours of endurance testing under variable loads and proven its functionality on a dynamometer. This engine delivers 675 horsepower at 3,200 rpm. Though, developers acknowledge the limitations of laboratory testing, noting that real-world performance and maintenance demands are best revealed through extensive fleet trials.
“Validation: bench runs help, but only long fleet trials expose real failure modes and maintenance drags,” the DRDO team stated in recent documentation.
The next phase, “Gen-2,” currently in the design stage, focuses on increasing power density without increasing the engine’s physical size, reducing thermal and acoustic signatures for modern battlefields increasingly populated by drones, and simplifying maintenance procedures. Planned improvements include more line-replaceable units, improved harness routing, and easier access panels. Software will play a larger role in fault isolation and mission-specific performance optimization.
A key challenge identified is the harsh operating habitat. “Hot, dusty environments punish gaskets, hoses, and electronics,” highlighting the need for robust design and rigorous testing. Gen-2 will undergo full climatic chamber testing and desert campaigns to address these concerns.
The development has broader geopolitical implications for South Asia. Domestic engine production promises to reduce downtime, lower import costs, and enhance India’s defense export potential. It also mitigates the risk of supply disruptions during crises. Neighboring countries will closely monitor the engine’s performance in mountainous terrain, where torque and cooling are critical for operational effectiveness. the experience of South Korea with initial issues on the K2 tank’s engine serves as a cautionary tale, emphasizing the importance of rapid feedback between troops, maintenance personnel, and designers.
The “powerpack” – encompassing the engine, transmission, cooling systems, filtration, electronics, and supporting frame – is considered integral to success. A failure in any component can compromise the entire system.
Looking ahead,hybridization is being explored as a potential upgrade path. Combining a diesel engine with an electric drive could reduce noise, lower thermal signatures, and provide instant torque for short bursts of speed, as well as enabling silent sensor operation. The modular design of Gen-1 and Gen-2 is intended to facilitate the integration of hybrid kits in the future.
Operational testing of the Gen-2 powerpack is slated for 2027.
