The new platform that will be used for the new Z4 and Supra is the same rear wheel drive platform that underpins the Toyota 86 and the Subaru BRZ and the platform will go through some further development to suit the new carís size and extra power.
In 2007, Toyota unveiled a conceptual sports car known as the FT-HS (second image from top). The new Supraís design and styling is said to follow the FT-HSís design closely.
Initial reports have mentioned that the new Supra will be mid-engined and with an all wheel drive layout. But instead, Toyota will use a variation of one of its hybrid systems that was developed for its Lexus line-up.
The hybrid system will use a 2.5-litres four cylinder turbocharged engine and pair it up with an electric motor which will spin the rear wheels. BMW instead will develop a new V6 hybrid system for the Z4. The system will generate around 400bhp and it is said to offer an above average straight line speed.
Toyota is said to work on a greater part of the platform while BMW will work on the suspension and handling of the car.
While Toyota has mentioned that the new Supra will be released some time in 2017, BMW has been rather tight-lipped on the launch of the next Z4.
