Int. "Concept Room" with stylists working on drawings of cars. Model makers looking at scale model of new car (as seen being photographed in reel one). Quarter scale model being made in clay. A full scale mock up is being made in wood. A model passenger is sitting in the drivers seat. A woman sits in another prototype to make sure her nylons are not laddered or her skirt caught in the door. She holds the steering wheel to show the fascia panel. Colour is perfected on another full scale model using lacquer paper held against the panels. Top shot of large engineering drawing office. A draftsman take a piece of paper to the engineering workshop. Engineer is working on the new 7 bearing crankshaft. CU of roller tappets and WS of Engine exposed and being hand cranked. A prototype is driven out of the factory and along a leafy country road. It drives across a forge and onto a test track. The prototype is driven through more water,over uneven surfaces, switch back humps,and up and down steep gradients.
Int. Quality control laboratory, men in white lab coats stuff, steel and alloy scrapings are analysed. Projection microscopes check the physical structure. A cabinet of virulent moulds grown in tropical conditions are used for testing fabrics and upholstery. Heat is applied to rubber. A Fatigue tester stresses a torsion bar until it snaps. WS of cars driven in a kind of treadmill testing strain. A camshaft is tested for hardness, and a loaded hammer is swung down onto a thin billet of metal and broken. Lots of dials as a tensile test stretches and breaks metal. Gear wheels are grind on another large machine, and a row of women workers rub each gear with a stone. More tests on gears, they are measured, paired, run, and listened to for any sounds of disharmony. Large complicated machines test the finished gear box.
