Description is missing crucial information: What is the condition for PWR, equal, greater than, or greater than or equal? What does the colors filter mean? (The description never said the car's color should be contained inside the array.)

Please follow standard Java coding practices: fields of a class should not be exposed directly; they should be private with a getter and setter of appropriate names (e.g getHorsepower and getPowerToWeightRatio).

Expected and actual are reversed in the test assertion message display.

Also, random tests are missing.

import java.util.List; should be added to initial code.
