# " PROOF OF THE PLUSES" 1955 CHEVROLET BEL AIR PROMOTIONAL MOVIE 87484

This short film touts the superiority of the 1955 Chevrolet Bel Air over Ford and Plymouth. The reasons given include high engine torque twisting power at the transmission (:14); matched rear axles (:23), better weight distribution provides traction to the rear wheels (:28), and better power-to-weight ratio (:39). These points are visualized as a Chevy is shown pulling 16 different full-size makes from other car companies (:48). A dynamometer ( 1:19 ) measures engine power. A special torque wheel is installed ( 1:27 ) for testing and the results are displayed on a torque meter ( 1:39 ). A burette ( 1:42 ) is used to measure fuel consumption at different speeds and an oscillograph (today called an oscilloscope) ( 1:47 ) calculates accelerating capabilities by time, distance, and speed. An engineer flips through the charts proving Chevrolet’s excellence ( 2:04 ). A Chevrolet, Ford, and Plymouth are put to the test in a controlled race ( 2:20 ). The three cars are comparably priced, have a V-8 engine, and a standard transmission. Three professional NASCAR drivers ( 2:41 ) are used that will alternate cars for each challenge. The first test is accelerating ability ( 3:24 ), in which the Chevy wins by more than a car length. The drivers trade cars for the return drive ( 4:05 ), and the Chevy again triumphs. The second test is hill-climbing ability ( 4:40 ) up a 7.2 grade, hitting 70 miles per hour. The Chevy does it easily. A much steeper 16% grade is now conquered by the Chevy,…
