New Flyer has been awarded a contract to supply an additional 50 forty-foot and 23 sixy-foot Xcelsior compressed natural gas heavy-duty transit buses for use on the San Diego Metropolitan Transit System (MTS).
The order comes during the fourth of a five-year contract first announced in 2022, with the latest purchase having been valued at approximately 64 million USD (including 96 equivalent units) and been added to NFI’s backlog for Q4 2025.

Each new vehicle will aid in the wider modernisation of the MTS fleet by replacing existing end-of-life buses with low-emission models designed to meet both the agency’s operational and service requirements, whilst also supporting skilled manufacturing jobs across New Flyer’s US operations.
Chris Stoddart, President, North American Bus and Coach, NFI, said:As one of the first transit systems in Southern California, MTS continues to lead the way in both safety and service quality.
Having partnered with MTS for more than a decade, New Flyer is proud to support MTS with clean, safe, and innovative CNG technology.
The new buses are expected to expand MTS’s ability to deliver mobility for both residents and visitors across San Diego County.
