Next year’s updated Boxster and Cayman lines will include the company's long-expected four-cylinder models, Porsche boss Matthias Mueller has confirmed this week.
Talk of a four-cylinder option in both ranges reaches back to at least 2008, but it was 2011 before former Porsche R&D chief Wolfgang Duerheimer confirmed that any such project was in the works.
Now, head honcho Matthias Mueller has told industry paper Automotive News that buyers will be given the choice of four- and six-cylinder powertrains from 2016.
Details on the new engine have not been offered, but earlier reports point to 2.0 and 2.5 litre versions of a turbocharged flat-four, with the capability to produce as much as 295kW.
In its current flat-six form, the most powerful Boxster is the newly revealed 276kW Spyder, driven by a 3.8 litre mill sourced from the 911 range, while the 3.8 litre Cayman GT4 offers an even meaner 287kW.
Regular Boxster and Cayman models are driven by 2.7 and 3.4 litre flat sixes, producing as much as 243kW in the GTS (and 250kW in the Cayman GTS).
Adopting a four-cylinder unit would offer the advantage of lower vehicle weight and improved fuel efficiency.
For now, it is unclear where the new four-cylinder models will slot into the range, although they could easily replace the current entry-level $102,800 195kW Boxster and $106,600 202kW Cayman models.
