Smaller Engine, Reduced Emissions, and Greater Fuel Economy

ise_dh-web

If diesel is your fuel choice and your goal is higher fuel economy and reduced emissions, ISE series diesel hybrid is the answer.

Our diesel series hybrid system uses the smaller Cummins ISB diesel engine, which helps to reduce fuel consumption, emissions, and noise. Our series diesel hybrid system utilizes electrically-driven accessories which are more efficient than engine-driven accessories used in conventional vehicles and competing hybrid drive systems, allowing the engine to be stopped without loss of accessory functionality. This results in further improvements in fuel economy and emissions.

  • Highest 40′ transit fuel economy based on independent testing (Altoona)
  • Reduced exhaust emissions
  • Diesel Fuel Accessibility
  • Series hybrid configuration benefits
  • Smooth and quiet operation
  • All electric accessory options available


Our series diesel hybrid kits will power vehicles of the City of New York Department of Sanitation (DSNY) for the cleanest of refuse trucks yet . 50 transit buses powered by our diesel hybrid systems will run a high profile operating route in Las Vegas as part of the sleek and modern Regional Transportation Commission (RTC) fleet.
