Currently, the CX-5 and the sleek new Mazda6 share many of the same platform components, and this architecture will already be scaled down to support the next-generation Mazda3 sedan and hatchback, which will debut later this year. Just-Auto.com states that all of Mazda's remaining front-wheel-drive vehicles will eventually switch to reworked versions of this Skyactiv platform, including the replacement for the larger CX-9 crossover.
Also of note, Mazda will reportedly be switching to shorter, four-year lifecycles for its vehicles. This means that the newly launched Mazda6 will be replaced for the 2016 calendar year, with a refresh coming sometime in 2014. That said, vehicles with platforms supplied by other automakers (like the upcoming MX-5 Miata replacement that will share its underpinnings with an Alfa Romeo product) will not necessarily follow this four-year rule.
