Toyota FT-4X will use TNGA Platform
The Toyota TJ Cruiser or FT-4X will be based on the TNGA (Toyota New Global Architecture) C-Platform.
This is currently being used by:
2017-Present Toyota Camry
2016-Present Toyota C-HR
2016-Present Toyota Prius Plug-In Hybrid
2015-Present Toyota Prius
This platform is a modular unibody platform that is capable of supporting front wheel drive, rear wheel drive, and all-wheel drive configurated vehicles of various sizes.
Of course we know the TJ Cruiser will be AWD if it plans on being the off-road contender that it sure looks to be so we have that going for us.
Perhaps a plug-in hybrid is possible for the future iterations of it though?
