Beyond Fleet 500: What Registration Data Reveals About the Fleet Fuel Transition

Commercial fleets are transitioning away from traditional fuels — but not in the way the conventional narrative might suggest.

Using commercial vehicle registration data from Global Mobility, Automotive Fleet examines how gasoline, diesel, hybrid, and battery-electric adoption has changed across vehicle classes over the past decade.

The data reveals a highly uneven transition. Hybrids are gaining significant ground in light-duty applications, electrification remains overwhelmingly concentrated in Classes 1 and 2, and diesel continues to dominate heavier commercial vehicles. At the same time, changes in the commercial vehicle mix itself are influencing the apparent shift in fuel share.

Join Automotive Fleet's Chris Brown and Nicholas O'Neil of Global Mobility as they dig into what the registration data actually shows — and what it means for fleet managers making vehicle and powertrain decisions today.

You'll learn:

• Why losing fuel share doesn't necessarily mean losing volume
• Why hybrids, not BEVs, are driving much of today's electrification growth
• Where electrification is — and isn't — gaining traction by vehicle class
• Why diesel remains dominant in heavier commercial applications
• How the changing mix of commercial vehicles is affecting overall fuel trends
• What the latest data means for your fleet's next three to five years

How does your fleet compare with others in your industry? Are your electrification plans keeping pace with your peers? What can the nation's largest commercial fleets teach you about vehicle strategy, fleet composition, and emerging market trends? Until now, those questions have been difficult to answer.

Join Automotive Fleet and Global Mobility (formerly S&P Global Mobility) for an exclusive first look at the registration data behind the new Fleet 500, representing more than 1.5 million commercial vehicles across North America's largest private fleets. Together, we'll reveal what the data says about fleet composition, electrification, hybrid adoption, truck populations, executive fleets, and industry-specific vehicle strategies—and, more importantly, what those insights mean for your fleet. Combining Automotive Fleet's industry expertise with Global Mobility's registration data, we'll show how fleet managers can benchmark their operations, evaluate vehicle strategies against industry peers, identify emerging trends, and make more informed planning decisions.

You'll leave with practical benchmarking insights you can apply to your own fleet — and a preview of the deeper analysis we'll present during The State of Commercial Fleets: A Registration-Based Market Analysis at the 2026 Fleet Forward Conference.
