Never before have so many test machines been built before beginning mass production and new machines have never been tested this carefully in the terrain and on a test bench before the launch.
Mitte kunagi varem ei ole enne massitootmise alustamist ehitatud nii suurel hulgal testmudeleid; esmakordselt on uusi masinaid ülima põhjalikkusega katsetatud nii maastikul kui ka stendil.
