Ashok Leyland marked a significant presence at Excon 2025 by unveiling its new P15 (49 & 55 HP) and H4 UniPack (55 & 74 HP) industrial engine solutions. Fully compliant with CEV Stage V norms, both engines have been engineered to deliver improved performance, enhanced fuel efficiency and long-term reliability across a wide range of off-highway and industrial applications.
Manufactured at world-class facilities and aligned with global quality standards, the new platforms reflect Ashok Leyland’s increasing focus on innovation and customer-centric engineering. The launch at the 12th edition of Excon, held from December 09–13 at BIEC Bengaluru, demonstrates the company’s commitment to advancing India’s industrial equipment ecosystem.
Designed as an integrated powerpack, the H4 UniPack offers 55 HP and 74 HP variants, making it suitable for demanding applications such as backhoe loaders and compactors. The platform provides high-altitude capability up to 5,500 metres, reliable cold-start performance and one of the best power-to-efficiency ratios in its class.
“The H4 UniPack is engineered as a complete solution; it shortens integration time and helps OEMs get their machines to market faster. “Its durability, fuel efficiency and ruggedness make it ideal for tough Indian duty cycles,” said Mr. Sathyanandan M, Vice President and Head – Power Solutions Business, Ashok Leyland
Equally prominent at the show was the P15 engine, offered in 49 HP and 55 HP variants. With a lightweight and compact architecture, the P15 is well suited for skid-steer loaders, sweepers, mini compactors, forklifts and similar compact equipment. Customers have multiple choices; a high-speed non-emission version up to 3300 rpm for faster cycles and a CNG variant for cleaner operations.
Mr. Sathyanandan emphasised “The P15 delivers strong pulling power in a compact form factor; customers get high performance with lower fuel consumption. These engines are versatile and easy to integrate across diverse applications.”
Co-Development; Multi-Fuel Readiness and Future Technologies
Both engines were developed after extensive co-engineering with customers, involving validation, productivity and fuel-efficiency trials typically spanning 18–22 months. The redesigned engine envelope was created to ease integration, especially in segments where established engines already exist.
Ashok Leyland has also ensured that the H4 and P15 platforms support alternate fuels. While primarily diesel, the engines can operate with up to 30 percent biodiesel and alcohol-based blends such as MD10 and ED15. A CNG option is already available on the P15. The company also showcased a hydrogen-ready H6 engine for future deployment.
“We are preparing for all future-ready fuel options; biodiesel and alcohol blends work effortlessly on our engines. “Hydrogen engines are progressing well; once the ecosystem matures, we will be ready for commercialization,” he said.
Serviceability remains a key advantage. The engines feature exceptionally low oil consumption, which directly improves Diesel Particulate Filter life under CEV V norms. With April 2026 bringing In-Service Monitoring requirements for industrial engines, Ashok Leyland plans to leverage its automotive experience to stay ahead of compliance needs.
The company also showcased a wider portfolio at Excon 2025: the A6 380 HP CRS engine, H6 hydrogen and flexi-fuel engines, H6 133 HP CEV V engine, an 82.5 kVA diesel genset, compact Flex EATS (Exhaust After-Treatment System) and airless DEF tank solutions.
“Our goal is to strengthen our leadership and penetrate segments where we are not yet dominant. With a wider range and deeper customer engagement, we aim to help businesses work smarter with solutions they can rely on,” added Mr. Sathyanandan.
