International Highlights (select examples):
Listing every international release is impractical. However, many manufacturers in Europe, Japan, and elsewhere introduced new models or updated existing ones in 1980. Some examples (though precise release dates might vary by country):
* Several models from Japanese manufacturers like Toyota, Honda, Nissan, and Mazda saw updates or new releases, many focused on fuel efficiency due to the global energy crisis. Specific models would require further research based on the region.
* European manufacturers like Volkswagen, BMW, Mercedes-Benz, and others would also have released new or updated models. Again, specifics require more focused research.
To get a more complete list, you'd need to specify a region (e.g., "cars released in the US in 1980") and perhaps consult resources like automotive archives, historical car magazines, or specialized online databases.
