The shame is that it takes the purchase this information which, in my opinion, should be given free of charge by consumer measurement organizations.
Pouted ... it's especially a shame that these standardized cycles do not correspond more to reality when they are not really the conditions that some believe ...

5.3. Description of the tests
5.3.1. Type I test (checking the average exhaust emissions after a cold start)
5.3.1.1. Figure I / 5.3 shows the different possibilities for the type I test.
This test must be carried out on all vehicles referred to in point 1 and whose maximum mass does not exceed 3,5 t.
5.3.1.2. The vehicle is installed on a dynamometric bench equipped with a system simulating the resistance to the advance and the inertia. 5.3.1.2.1. With the exception of the vehicles referred to in point 8.1, a test is carried out without interruption for a total duration of 19 minutes 40 seconds and comprising two parts ONE and TWO. The idle period between the last deceleration of the last elementary urban cycle (part UN) and the first acceleration of the extra-urban cycle (part TWO) may, after agreement of the manufacturer, be extended by a period without sampling of maximum 20 seconds in order to to facilitate the settings of the test apparatus.
5.3.1.2.2. The UN part is made up of four elementary urban cycles. Each elementary urban cycle is made up of fifteen modes (idle, acceleration, stabilized speed, deceleration, etc.).
5.3.1.2.3. Part TWO is made up of an extra-urban cycle. The extra-urban cycle is made up of thirteen modes (idle, acceleration, steady speed, deceleration, etc.).
