A Continuation Platform
Mazda is currently working on a new FR architecture that will underpin future rear-wheel-drive models like the next-gen Mazda 6 and Mazda CX-5. But while a modular platform of this type may seem like an ideal fit for the MX-5, these vehicles will all be compatible with hybridization, and crucially, all-wheel-drive, which adds weight and complexity to the platform.
This goes against the Miata ethos, which is why we re more inclined to believe that the NE (fifth-gen) MX-5 will ride on an advancement of the current H-frame Skyactiv chassis. In this way, the NE will be to the ND as the NB was to the NA - an advancement and a refinement more than a completely revised model. In doing this, Mazda will be able to retain current developments and reduce the development costs. And, considering the ND is the lightest and smallest since the original, the NE will still be suitably compact and lightweight.
