All car engines must be cooled. But how?
Conventional cars are cooled by water. The Volkswagen engine is cooled by air.
The advantages are astonishing, when you think about it. Your Volkswagen cannot boil over in summer or freeze in winter, since air neither boils nor freezes.
You need no anti-freeze. You have no radiator problems. In fact, you have no radiator.
In midsummer traffic jams, your VW can idle indefinitely, while other cars and tempers boil.
The doughty Volkswagen engine is unique in still other ways. Its location in the rear means better traction (in mud, sand, ice, snow, where other cars skid, you go). And since it is cast of aluminum-magnesium alloys, you save weight and increase efficiency. Your VW delivers an honest 32 miles to the gallon, regular driving, regular gas.
And you will probably never need oil between changes.
