The D25 Engine is currently in production and is BS6 compliant.

The basic engine structure still retains the original configuration of 2 valves/cylinder and pushrod operated with the engine camshaft located in the cylinder block.

Author’s note – This engine has the longest legacy, starting off as the BD144 (MD2350) engine in the early 70s. The basic structure has outlasted even the most modern engines. It is a great achievement that the basic engine is currently in operation in a BS6 avator and still one of the most fuel efficient engine in the segment. Credit goes to the Mahindra R&D Engineers for keeping the engine alive by doing frequent redesign and upgrades in meeting the ever changing customer and regulatory requirements.
