Toyota has been developing an H2ICE engine that produces energy by burning fuel, as opposed to using hydrogen to run fuel cells (Top Speed, El Adelantado). A "specific production vehicle model" means a named vehicle intended for mass production and sale to the general public, not a concept car or a vehicle solely for testing or racing purposes. "Major global markets" are defined as Japan, North America (i.e., the US and Canada), and Europe (i.e., the EU and UK). The outcome will be determined by official press releases, announcements on Toyota's official websites for these regions, and confirmed reports from reputable automotive news outlets indicating a specific model and its intended market availability. The particular model year must be included in the announcement to count.
