Mazda may not have the official specs for the new MX-5 Miata available yet but there are some things we can expect to see in the new car.

Platform:

As far as platforms go there are two main options for the MX-5 Miata. the first option is the new FR architecture that will underpin the Mazda6 and CX-5. The other is that the car will be on an a new version of the current H-frame Skyactiv chassis.

The H-frame seems the most logical because of how lightweight it is but if Mazda is so invested in the new FR architecture they could want try it out on the MX-5.

Engine/transmission:

If Mazda can't continue to use the Skyactiv-G engine in the NE MX-5, they'll have to use their new Skyactiv-X engine to prevent the MX-5 from being a casualty of emissions regulations. The 2.0-liter Skyactiv-X motor utilizes a supercharger in conjunction with spark-controlled compression ignition and a 24-volt supplementary electric motor to generate 188 hp and 177 lb-ft.

A manual should remain the default choice of transmission with an automatic option available.
