The project was planned under the leadership of Akio Toyoda, president of Toyota Motor Corporation. This car was an attempt to revive the famous Toyota Levin/Treno (AE86), also known as the Hachi Roku, in the modern era. The development was a joint project between Toyota and Subaru, and while the development of the body structure was led by Subaru, which had a capital relationship with Toyota, the formulation of the concept was led by Toyota. As a result, Subaru's unique horizontally opposed four-cylinder engine was installed, and the engine's fuel injection system was derived from Toyota's. While its sibling, the Subaru BRZ, was set up with an emphasis on stability, the Toyota 86 was set up with an emphasis on slide control of the rear tires, making it more suitable for drifting. President Akio Toyoda has also stated that the 86 was developed as a car that develops the driver like the former Levin/Treno (AE86), and while the car responds directly to the driver's actions, it also reflects those actions even if they are performed incorrectly, which is a rare characteristic in this day and age.
