2015 Porsche Boxster GTSEnlarge Photo
Porsche officials have been talking about the possibility of a four-cylinder engine for the next-gen Boxster and Cayman since at least 2008. And in 2011 a senior Porsche exec confirmed that a four-cylinder engine with a horizontally-opposed ‘boxer’ design was in fact in the works. Now, Porsche CEO Matthias Mueller has echoed those earlier claims and revealed some specifics on the new engine.
“We will continue with the downsizing strategy and develop a new four-cylinder boxer engine which will see service in the next-generation Boxster and Cayman,” Mueller revealed to Auto Motor und Sport. “We will not separate ourselves from efforts to reduce CO2.”
When asked how much power Porsche’s flat-four would produce, Mueller said up to 400 metric horsepower, which is approximately 395 regular horsepower. The most powerful versions of the current Boxster and Cayman are the recently revealed GTS models, which produce 330 and 340 horsepower respectively.
Given Mueller’s performance claims for the engine, we may even see it end up in the 911. A Porsche engineer has previously stated that the automaker was not averse to using four-cylinder engines in its iconic sports car, and more recently the new 919 Hybrid Le Mans prototype, which features a V-4 engine, was billed as the essence of Porsche.
Considering that the next generation of the Boxster and Cayman sports cars aren’t due until the end of the decade, it may be some time before we see Porsche’s new four-cylinder boxer put into use. Of course, we’ve also heard that it might appear in facelifted versions of the current car due around 2016. It is expected to displace about 2.5 liters and feature direct-injection and turbocharging technologies to maximize performance and efficiency.
Note, a modern four-cylinder Porsche is slated to arrive as early as this year. Yes, later this year Porsche is expected to add four-cylinder engines to its Macan crossover, though these will be Volkswagen Group units. They will be 2.0-liter straight-fours, one gasoline-powered and the other a diesel, and neither is expected to be offered in the U.S. market.
