apr first brought the Prius to Super GT in 2012 and has continued to run the car with various hybrid systems since then, most recently with a supercapacitor.
After some early reliability troubles, apr successfully transformed the car into a regular championship contender, finishing second in the standings twice during the last four years.
However, with the Prius’ mid-engine layout outlawed for 2019, the team was forced to design an all-new car to stay in the category.
The new generation Prius, which complies with the front-engine layout requirement, was first seen at Fuji Speedway in December and was officially unveiled by apr on Friday.
The car will run on a Lexus RC F GT3-sourced 5.4-litre V8 engine, mated to the same supercapacitor used in the previous generation Prius.
The new engine replaces the old 3.4-litre V8 motor that was derived from older Toyota Super Formula and Lexus GT500 cars.
As far as the driver line-up is concerned, Yuki Nakayama will leave Team UpGarage to join Koki Saga in the Bridgestone-shod #31 Prius.
Hiroaki Nagai will continue to drive the #31 car that will run on Yokohama tyres and will be paired alongside Manabu Orido.
The announcement means Kohei Hirate will leave apr Racing after just one season, lending credence to reports he is set to join Nissan's GT500 roster.
