Cummins rolled out the latest generation Heavy Duty engine, the 2017 X15, at its Jamestown Engine Plant in Jamestown, NY on Oct. 1, 2017. The engine is a game-changer in terms of reliability and fuel economy.
Cummins has received certification for its complete lineup of on-highway diesel and natural gas engines ahead of schedule from the U.S. Environmental Protection Agency (EPA), meeting both the current EPA regulations and the second step in greenhouse gas (GHG) and fuel-efficiency standards which take effect in January 2017.
Fuel efficiency is improved across the commercial vehicle engine lineup from 5.0 liters to 15 liters.
Cummins today unveiled a revolutionary new system for its ISB engines that brings the fuel economy benefits of stop-start technology to conventional buses. The technology, which saves fuel by shutting down the engine when a vehicle is not moving, had only previously been available on far more expensive diesel-electric hybrid buses.
