Porsche-Boxster-S

Think naturally-aspirated flat-six engines in Porsche’s smaller Boxster and Cayman models are the bee’s knees? Stuttgart had better batten down the hatches, then, as it has confirmed that future versions of these cars will receive turbocharged four-cylinder engines as early as next year.

According to Automotive News, CEO Matthias Müller has said that Porsche will begin selling flat-four cars in the United States in mid-2016, over 20 years since they last sold a four-banger there in a 968.

“First of all, we will have it in the Boxster and Cayman successor,” he said. “And then we will see how it works and how successful it is and how the customers will react on that, and then we will take the next decisions.”

Müller himself said last year that the flat-fours were coming, and Porsche executives have reportedly confirmed that the engines will appear in the facelifted Boxster and Cayman.

Technical details remain sparse, but the flat-fours are expected to be turbocharged and will be available in both 2.0 litre and 2.5 litre displacements. Apart from lowering weight – which should improve both fuel efficiency and handling – the engines could produce as much as 400 PS, as Müller previously suggested.

When they arrive, the four-pot Boxster and Cayman will join the Macan, which has a turbocharged 2.0 litre inline-four producing 237 PS from 5,000 to 6,800 rpm and 350 Nm from 1,500 to 4,500 rpm.
