Porsche R&D boss confirms flat-four engine under development for Boxster and Cayman

It’s been rumored for some time, but we now have confirmation – Porsche is working on a brand-new four-cylinder engine, to help meet increasingly stringent emission regulations.

“We are working on a flat-four engine,” Wolfgang Hatz, Porsche’s R&D chief confirmed. “For me a 911 is a six-cylinder car, it cannot be a four-cylinder. The Boxster and Cayman on the other hand, we are deciding if it fits.

“Developing a flat [boxer] engine is more expensive, but that’s our heritage and it has to be that way,” Hatz continued. “I think the market will definitely accept a four-cylinder Porsche. Downsizing is a fact of the industry now.”

Possibly 2.5-litres in capacity (the Carrera S’s 3.8-litre flat six, minus two cylinders) and turbocharged to achieve performance and emission targets, a four-cylinder engine would create a lower entry-level price point for the Boxster and Cayman, making Porsche ownership more accessible than ever.

However, according to Hatz a smaller capacity engine doesn’t pave the way for a smaller sports car: “No, there’s definitely no room below the Boxster,” he insisted.
