As some of you may know, Ferdinand Porsche designed the Volkswagen Beetle, and he considered it his greatest achievement. He rated the VW higher than his winning race cars because this was a car every family could afford. It was a masterpiece of economical engineering for its time, as is evidenced by the fact that the basic design survived for so many years. Volkswagen still makes a version of it today, although it is quite different under the hood. In fact, the engine is no longer under the same hood. It used to be in the back of the car. Now it is in the front.
