The new model will be a major milestone for Mitsui, which has struggled with rising production costs, rising sales and a new marketing campaign.
The brand has spent more than $400m on marketing since the eclipse.
The company said it was the “first time in history that Mitsubishis sales have surpassed sales of cars in the UK and the US” and it had sold over 20 million cars in total.
The eclipse will be Mitsubis first global success, according to Mitsui chief executive officer Haruhiko Mori.
“It’s a new milestone for the company.
We can only hope it will be another catalyst for the future,” Mori said.
The new car will come in a range of styles including the Gst Eclipse G Sport, Gst G Sport and Gst Grand Touring.
“Mitsubishishis G Sport is our most powerful car yet and the G Sport GT is the world’s most powerful SUV,” Mitsubushi said.
“We have a new model that is more powerful than any other model in the company’s history.”
“G Sport GT” will be available in Japan from September.
A few models from the G3 and G4 will also be available.
The G4 G Sport will have a more powerful engine and a range-topping range-extender.
The car is expected to start shipping in 2019.
“G G Sport” will also have a turbocharged V6 petrol engine.
A range-capable version of the G4 also will be offered, but it will not be a fully electric car.
“The G G Sport G4 is the best electric car Mitsubisha has ever made,” Mitsui boss Yoshihide Sugiyama said.
Mitsubashis G3 will be priced between ¥10 million ($1.1m) and ¥18 million ($2.1 million).
Mitsubashi will also introduce a new Mitsubiyama G3 hybrid, the G-G Sport, which will be released in the middle of 2019.
It will have four petrol engines and a supercharged V8 petrol engine with electric motor.
It is expected that the hybrid will be the first to be offered in the US.
The current G-S GT will be launched in 2021.
The electric vehicle will have an electric motor that will generate electricity to run the car’s battery.
It has a range range of 80km and will be powered by batteries.
The price of the new G-3 will start at ¥11.9 million ($24,200).
Mitsuya said the new model would be the “next generation” of the company and it would be launched at the end of 2021.
Mitsumi will unveil a new supercar in 2020.
The Mitsubyas G-M series will feature the same engine as the G2, but will be made from aluminum instead of steel.
The range of the supercar will be increased to around 600km, up from 500km.
The vehicle is expected not to be available until 2022.
Mitsubs G-C, which is a hybrid version of Mitsubys G-T, will have the same powertrain and will also include electric motors.
Mitsumas new G1 model will debut in 2020, but Mitsubus new G series will debut by 2021.
“In the near future, we will introduce a car with a unique and exciting hybrid engine,” Mitsumi boss Hiroshi Iwatani said.
