Metroking Taxi Manufacturing(ST8552-1)

MetroKing Motors, LLC


Metroking Motors, LLC developed the Metroking Taxi, a body-on-frame vehicle derived for a standard General Motors pickup truck and equipped with a passenger module, enabling the vehicle’s use as a wheelchair-accessible taxi. The vehicle is more fuel efficient than comparable paratransit vehicles and is designed for easy introduction of subsystems that would further improve fuel economy.

Project Description

In Phase 1, NYSERDA provided support for production of 10 units of the Metroking Taxi for use in field tests and preliminary sales efforts. In Phase 2, NYSERDA provided support to find and implement ways to reduce Metroking Taxi manufacturing costs so the vehicle can be sold at a price low enough to assure successful commercialization. In Phase 3, NYSERDA provided support to identify market barriers and to perform a one-year demonstration program to collect data for assessing the relative merits of the Metroking Taxi in commercial service.


This product can reduce the fuel consumption and exhaust emissions of taxis used in New York City and elsewhere. Metroking Motors plans to initiate vehicle manufacturing in New York State.

Project Results

Metroking established a pilot facility in Poughkeepsie (NY) to perform final vehicle assembly and to support a demonstration program in conjunction with local taxi operators, and is initiating product sales efforts. A 200,000-mile field test was executed and showed a 23% fuel economy advantage for the Metroking Taxi versus standard vehicles used by the participating fleets.
