It was the counterpart of the Corona EXiV. Its design sought to emulate the hardtop four-door coupé styling of large American and European sedans, resulting in a small, low cabin with longer front and rear ends. The ED's B-pillar stood up in the middle with no purpose other than to hinge the rear door on; it was not attached to the roof side of the cabin. The ED achieved huge sales in Japan, and other Japanese manufacturers introduced the Mazda Persona, Nissan Presea, and Mitsubishi Emeraude around the same time. "ED" is the initials of "Exciting" and "Dressy". When the Carina ED was discontinued, the Toyota Brevis appeared for the market segment served by the Carina ED.

Although the rotary-engined sports prototypes generally had a reputation of being very reliable, the Mazda GTP frequently failed to finish races, and was never able to better the eighth place achieved at the 1983 24 Hours of Daytona. In 1986, one car was purchased by Erie Scientific Racing, and rebuilt to become the Badger BB. This car was no more successful or reliable than its predecessor, and was last used in 1989, by which point it was owned by Jack Engelhardt. The other car, meanwhile, was rebuilt by Honegger into the Denali Speedcar, which was used with moderate success in 1986 and 1987.

Document 11: Hyundai Dynasty: The Hyundai Dynasty is a premium executive sedan that debuted in 1996. The features of the Dynasty were electronically controlled suspension, dual climate control, and power memory seats (front and rear). In order to differentiate the Dynasty from its platform-shared smaller Grandeur, Hyundai used a different badge (stylized D logo) for Dynasty. The Hyundai Dynasty was produced in Ulsan, South Korea and it was discontinued in 2005. The Dynasty was the top level flagship at its introduction, but it was a front wheel drive vehicle. It had a higher level of luxury equipment and was available in extended length versions over the more basic Grandeur. When the joint luxury flagship Mitsubishi Proudia/Hyundai Equus was introduced, the flagship designation was then removed from the Dynasty and sales suffered as a result with cancellation.
