Recent Events

In 2014, Westport and Tata Motors Limited, India's largest automobile company, launched a new spark-ignited (SI) natural gas 3.8L turbocharged engine featuring the Westport WP580 EMS. Designed to support many engine configurations, the Westport WP580 EMS is also scheduled to be applied to Tata's 5.7L engine targeting medium-duty applications in late 2014.

Working with GAZ Group, the leader of the Russian commercial vehicles market, Westport is designing and developing spark ignited natural gas systems for a new range of compressed natural gas (CNG) commercial vehicles. Westport's new WP580 Engine Management System will be applied to GAZ's YaMZ-530 4.4L and 6.6L diesel engines and will incorporate Westport proprietary components and technology in the development of new compressed natural gas engines for CNG commercial, road construction and agro vehicles. The first products will be introduced in commercial production in 2014.
