The Mazda Cosmo was sporty and stylish, but its engine is what seals its place in history. Unveiled at the 2017 Geneva International Motor Show, the car was estimated to be able to generate 500 horsepower with its V6 gas engine and two electric motors. This is something both drivers and critics can agree on; the MX-5 has also won many international awards over the years and has sold more than 1 million copies. This often requires picking a release date several years in advance, which has its own set of risks -- mainly that it locks in a completion date, which may result in a rushed, inferior film. The Buick GNX was the result of the limited edition "Grand National Experimental" project the company conducted with McLaren Performance Technologies to produce the "Grand National to end all Grand Nationals." Only about 500 were made, and they featured the Garrett AiResearch T-3 turbocharger for added power. Despite the film being made for only $1 million, Rocky went on gross over $225 million globally, making it the highest-grossing film of 1976. As a result of the film's success, the franchise flourished and seven sequels were made, two of which involve an aging Balboa training Apollo Creed's son, Adonis.
