Mixed Energy Fleet Tips for Balancing EVs, Gas and Diesel Vehicles

The conversation around fleet electrification often focuses on a single question: When will fleets switch to EVs? In reality, most fleets are asking a very different question: How do you successfully manage a mix of EVs, gasoline vehicles, and diesel-powered assets while maintaining operational efficiency, controlling costs, and meeting your business's unique demands?

That challenge is driving the rise of mixed energy fleets across North America.

Rather than replacing entire fleets overnight, organizations are taking a more strategic approach. Many are identifying specific applications where electric vehicles make sense today while continuing to rely on traditional fuel vehicles for routes, duty cycles, and operations that may not yet be ideal for electrification.

The result is a more complex operating environment that requires fleet managers to balance multiple fuel types, charging infrastructure, vehicle utilization, maintenance considerations, and evolving cost structures.

In this episode of TruckChat, Lauren Fletcher speaks with Sarah Booth of WEX and Sawatch Labs about what fleet managers need to know as mixed energy fleets become increasingly common.

Their discussion explores how organizations are evaluating total cost of ownership, why fuel price volatility continues to influence fleet decision-making, and some of the biggest misconceptions surrounding fleet electrification. They also dive into one area that many organizations underestimate when beginning an EV transition: charging strategy and infrastructure planning.

The conversation highlights why successful fleet electrification is rarely an all-or-nothing proposition. Instead, the most effective fleets use data to determine which powertrain is best suited to specific applications and to build long-term strategies that support operational goals.

As charging networks expand, vehicle technology advances, and fleet management platforms continue to integrate fuel and charging data, the decisions fleet leaders make today will shape how efficiently they operate tomorrow.
