It seems the mid-cycle refresh Toyota is planning for the GT 86 is more complex than originally believed as a prototype was seen testing on the 'Ring featuring what appears to be a carbon fiber hood with dual air intakes to increase engine cooling. The same lightweight material was also used for the roof and trunk where we also notice a large fixed wing.

For the moment it's not known whether these added parts will be available through a special edition GT 86 or will be offered as an optional package. GT 86 chief engineer Tetsuya Tada recently said the facelifted GT 86 could make use of a larger boxer engine along with improved exhaust and intake systems developed in collaboration with Gazoo Racing. Also expect to find a modified final drive ratio for more intense accelerations.

Following the 2015 GT 86's introduction, Toyota will start work on the second generation model which might end up being co-developed with BMW rather than Subaru. The model could be offered with some form of hybridization and will be out before the end of the decade.
