For years now the decline of the V8 engine in traditional passenger cars has been well documented. Even sports cars are moving away from the hulking powerplants. But could the V6 see a similar fate?

It certainly will at Mazda, confirms Robert Davis, the brand’s US boss, commenting in a recent interview that the company has no plans to build new V6 engine using the brand’s new Skyactiv engineering philosophy.

Introduced in the 2012 Mazda3, Mazda’s first Skyactiv 4-cylinder engine makes use of numerous fuel saving technologies from lighter components and lower friction surfaces, to direct injection, variable valve timing and an ultra-high compression ratio.

In the past, only the Mazda6 and CX-9 were available with a V6 powerplant. Mazda has been quiet on plans to build a turbocharged 4-cylinder, although it’s likely one is in the works. Another possibility is a hybrid 4-cylinder that could deliver V6 power with exceptional fuel economy. Plus, there’s the strong possibility that Mazda will offer a Mazda6 diesel, as previewed in the Takeri concept (above).

In addition, Davis did confirm Mazda is currently exploring the future of the Rotary powerplant, both for conventional use and also as a rang extender to help charge a battery pack for an electric motor.
