Where did the term Turbo-Jet come from?

The TURBO-JET Marketing Plan: During the heart of the 1960s, the Big 3 automakers were in a heated horsepower battle and the marketing departments for all three companies recognized that cubic inches and horsepower figures wasn’t a good enough marketing plan. The engine must also have a proper name that portrayed the vehicle’s image. Oldsmobile chose the Rocket V8 to capitalize on the country's interest in space travel. Buick chose the name Wildcat. Ford had a Police Interceptor 390 V-8, while Chrysler Corporation chose Ramcharger, Golden Lion and Commando for their three divisions. Chevrolet wanted its new big block engines to reflect the current innovations in aviation. So they created the Turbo-Jet engine family, complete with a cross-flags fender badge.
