* Air-cooled engines: These engines, often found in older Volkswagens and motorcycles, use fins on the engine block to transfer heat directly to the surrounding air.
* Electric vehicles: Electric cars don't have combustion engines and don't require radiators for engine cooling. Instead, they have liquid-cooled batteries and electric motors that utilize different cooling systems.
* Hybrid vehicles: Some hybrids use a combination of internal combustion engines and electric motors. While they may have a radiator for the engine, they may also use other cooling systems for the electric motor and battery.
So, while the term "car without a radiator" can be misleading, some vehicles do exist that don't rely on a radiator for cooling. It's important to remember that the specific cooling system used depends on the vehicle's design and power source.
