The Toyota Supra is a sports car/grand tourer that was produced by Toyota Motor Corporation from 1978 to 2002. The styling of the Toyota Supra was derived from the Toyota Celica, but it was both longer and wider. Starting in mid-1986, the Supra (in its third generation, Mark III) became its own model and was no longer based on the Celica. In turn, Toyota also stopped using the prefix Celica and began just calling the car Supra. Owing to the similarity and past of the Celica’s name, it is frequently mistaken for the Supra, and vice versa. First, second and third generation Supras were assembled at Tahara plant in Tahara, Aichi while the MKIV Supra was assembled at the Motomachi plant in Toyota City.
The Supra also traces much of its roots back to the Toyota 2000GT with the main instance being its engine. The first three generations were offered with a direct descendant to the Toyota Crown’s and 2000GT’s M engine. All four generations of Supra produced have an inline 6-cylinder engine. Interior aspects were also similar, as was the chassis code “A”.
