Is a 1968 beetle air cooled?
Yes. Four cylinder air cooled engine.
An air cooled car will be lighter. The air cooled engine has a single thin walled engine block for air cooling just like an air cooled motorcycle or early VW Beetle. There is no antifreeze, radiator, water pump, hoses, etc, that a water cooled car would have. The water cooled engines have two walls (an inner wall for the pistons, etc, and the outer wall to hold the water) to help carry the water around…
Well for starters, the 'New Beetle' has the engine located in the wrong place. ;-) It's in front, not in back like the original Bugs. Other key differences are that the New Beetle is water vs. air cooled on the older cars. The new model also has many modern day amenities, the classic Bugs were fairly minimalistic in design.
It has an air cooled engine. Early beetles (original - not new beetles) are air cooled - they have a large fan, big cooling fins on the cylinders and a ducting system ("tin" to vw nerds) that direct air around the cylinders to cool the engine. Also an oil cooler ( a mini radiator within part of the tin duct system) that the oil circulates thru.
