Motor Trend Car Road Tests
Description
The data was extracted from the 1974 Motor Trend US magazine, and
comprises fuel consumption and 10 aspects of automobile design and
performance for 32 automobiles (1973-74 models).
Usage
cars74
Format
A data frame with 32 rows and 11 variables. The variables are
as follows:
- auto
highway miles per gallon
- mpg
Miles/(US) gallon
- cyl
Number of cylinders
- disp
Displacement (cu.in.)
- hp
Gross horsepower
- drat
Rear axle ratio
- wt
Weight (1000 lbs)
- qsec
1/4 mile time
- vs
Engine cylinder configuration
- am
Transmission type
- gear
Number of forward gears
- carb
Number of carburetors
Details
This dataset is the mtcars dataset that comes
with base R. However, cyl, vs, am, gear
and carb have been converted
to factors and rownames have been converted to the variable auto.
A description of the variables by Soren Heitmann can be found
