cars: Performance data for cars from Motor Trend magazine

In SMIR: Companion to Statistical Modelling in R

Description

The data are quarter-mile acceleration time in seconds and fuel consumption in miles per (US) gallon for 32 cars tested by the US Motor Trend magazine in 1974. Nine explanatory variables are given: shape of engine, number of cylinders, transmission type, number of gears, engine displacement in cubic inches, horsepower, number of carburettor barrels, final drive ratio, and weight of the car in thousands of pounds.
