DOE's Transportation Technologies Office, formerly the Vehicle Technologies Office, funds research, development, demonstration, and deployment for efficient and affordable transportation. It now sits under DOE's CMEI structure and focuses on non-battery vehicle technologies, advanced propulsion materials, energy-efficient mobility systems, and off-road, rail, marine, and aviation propulsion.

The office uses program-wide FOAs and topic-specific lines such as LightMAT, EEMS, ORMA, and SuperTruck 3. SuperTruck 3 alone totals $127 million over five years with a 1:1 federal and recipient match, and the 2022 awards ranged from about $18 million to $33 million for major heavy-duty truck and charging-system demonstrations. The office's broader work continues through lab and industry partnerships, while battery R&D now sits elsewhere in DOE's reworked structure.

TTO is a good fit for teams that can show a path from materials or component R&D to a vehicle-scale demonstration. Large OEM-led collaborations, national-lab consortia, and cost-shared deployments tend to match the office's style better than small exploratory proposals.
