There are, AIUI, about 160 countries in the world.
If you really want such a list, start there and scratch off the 20% or so who DO manufacture complete cars.
Do they have to make all the components domestically? The trend seems to be to make a few, then export them, then import a few and then have a foreign company sent in parts to assemble for the local market (Honda in Ohio, Toyota in Texas, VW in wherever…)
This isn’t a hard problem in general. It is just simple set theory. Only a few countries produce the vast majority of vehicles in the world and they are all on the list. There are currently 196 countries in the world and the vast majority of them do not produce any vehicles.
What is the definition for “manufacture or produce a vehicle”? Does a custom shop in Laos count? I am fairly certain that the Vatican and Monaco produce exactly zero as do most other countries ranging from Papua New Guinea to Suriname unless you want to get really creative with definitions.
Finland has one car factory in Uusikaupunki currently making Mercedes Benz Class A cars. It’s a contract factory so it makes whatever cars it can get a contract for, not a Mercedes Benz factory, but it only makes cars.
Cars are often part of a country’s culture and identity. Ford and Chevy in the US. BMW in Germany. Renault in France. UK had BMC with the Mini. Even the Soviets had the Lada, ZiL and Volga. The roads in these countries were filled with cars they manufactured. A lot has changed with Globalization and imports. But you still see a lot of Renault’s in France and BMW’s in Germany. Lots of Ford’s and Chevy’s in the US.
I was curious which countries didn’t have their own manufactured cars.
