Exploring cars data with ALTAIR

Looking at cars manufactured between 1970 and 1982, what is the repartition and evolution of the performance in terms of miles driven for one gallon of oil.
Is there a correlation between the car consumption, the horsepower and country of origin?
The majority of cars in the dataset have a performance less than 30 miles per gallon. This correspond to car built until the late 1970's.
