Premium performer Unique among engine platforms, the 8.9-litre L Series combines the robust characteristics of a higher displacement, heavy-duty engine with the efficiency and lower operating costs of a smaller, midrange engine. This fusion of attributes gives the ability to power a remarkably broad range of vehicles, while delivering premium levels of performance and has earned a reputation for dependability unsurpassed in industry, tailored to every application.  

Moving Forward To Near Zero​ Latest design enhancements to the L9N natural gas engine have achieved close-to-zero emission levels, below that of the Euro VI standard. This leap forward is achieved while retaining the simplicity of a passive ‘fit and forget’ aftertreatment. Sharing the same engine block as the high-strength L9 diesel brings the benefit of 80 percent component commonality between the two engines. Ideally suited for bus, coach and truck applications with cleaner and quieter operation.​
