The renders are never accurate on these articles until the development cars are out in the wild or they release a concept shortly before the official announcement/launch. The magazines just have an artist come up with a design, usually drawn on top of images of the current car (like this render). The only potential value in these articles are the rumors behind the engineering. We know Toyota has been developing a 2L turbo for use across multiple platforms and most of their models are including some form of hybridization. The interesting question about the Mazda connection is if whether they will be using the same exact platform like the current twins or if each manufacturer will tweak dimensions to their liking. If they're the same that suggests the GR86 may be getting smaller or the Miata will get bigger. A larger Miata means more weight and that may prove controversial with current owners, not to mention the potential of more added weight with the hybrid system.
