The automobile is one of the key inventions in our society. Since we have known it all our lives, we can remember how much it has changed if we think about it a little. Since the time it was first available to the public in mass quantities, it has gone through an extensive amount of innovative improvements.

The 2.9-liter engine of the Model T produced about 20 horsepower and got between 13 and 21 miles per gallon. Current car engines produce anywhere from 90 horsepower to over 500 horsepower.
