Comparative testing of cars for a quarterly consumer magazine poses a particular set of problems. The main ones are time and the designing of apparatus to produce objective comparisons between cars. A subsidiary, but important, problem is the need to produce information which is technically valid and yet readily interpretable by a non-technical public. A test unit is described, and a typical test programme is outlined. Examples are given of the way in which particular problems have been overcome: in particular, the evolution of equipment for measuring acceleration, which has reduced the time necessary for testing by 75 per cent, is described. The development of comparative tests for handling is discussed, and the difficulty of defining a simple measurement of the noise inside a car is used as an example of the difficulty of producing objective measurements which correlate with subjective impressions. It is concluded that, whilst rationalization of test methods is often both desirable and practicable, it is sometimes necessary for individual organizations to retain their own particular methods.
