At one point in 2003, Hasbro stated that the Alternators line would consist of "six 'hot' contemporary cars". The first six models were based on a Subaru Impreza, a Dodge Viper, a Jeep Wrangler, a C5 Chevrolet Corvette, a Mazda RX-8 and a Ford Mustang GT. Even before the line was launched, though, new licenses were already pursued by Hasbro and Takara, with the first new mold that was not part of the "original six" anymore being based on a Honda S2000. More and more models and manufacturers joined the line over its run. Nearly all of these models are from either American or Japanese manufacturers, with the only exception being the Jaguar XK, which is originally a European car.
