Detroit-based startup ZMD Motors is developing a battery electric retrofit package for Ram's medium-duty 4500 and 5500 series work trucks. The package is designed to meet the needs of vocational fleet buyers who have limited options to electrify. This could significantly reduce fuel and maintenance costs, and increase access to noise-regulated neighborhoods. However, if successful, this could be a big if. ZMD's founder, Dave Stenson, believes that the platform could provide significant market data for larger manufacturers like Ram or Lightning eMotors. Despite this, there are currently no battery or motor specs, range specs, and layout details for the trucks' layout.
