The Good (?) Old Days

Eighteen vehicles ranging from a 1938 Dodge to a 1965 Mustang were tested to determine their fuel economy and exhaust emissions relative to today's vehicles and today's driving conditions. The 1979 models are getting about 10% better fuel economy over the urban cycle and 20% better over the highway cycle than the older vehicles. The reasons for these differences as well as the exhaust emissions from the older vehicles are also discussed.
