In the Facebook comments, I already see people equating the upcoming 718 engines with Subaru EJs. Now, when has Porsche ever not blazed their own trail? Porsche will almost certainly ensure this engine will generate glorious (or at least non-nasty) sounds. Subaru’s trademark sounds are due to the EJs running unequal-length headers. I highly doubt Porsche will do something stupid like adopt unequal length headers, especially if they opt to use twin-scroll turbochargers. With luxury-sport cars such as these Porsche variants, they’re going to ensure the car sounds like it looks…fast, powerful, and sleek.
Boxster and Cayman turbocharged flat fours will have between 240 and 370 HP, per Road & Track magazine:
Here’s how the pie is being cut: base model cars should see 240 hp from their single-turbo two-liter. Step up to an “S” and displacement jumps to 2.5 liters, and output would be 300 hp. GTS models would receive a 370 hp 2.5-liter, a little below what Porsche CEO Mattias Müller indicated would be the theoretical maximum output of a turbo flat four in the Boxman.?
Car & Driver reports:
Only the ultra-high-performance Boxster Spyder and Cayman GT4 are said to retain their naturally aspirated flat-six engine, a 3.8-liter unit. Which is sure to make them even more highly desired than they already are. Meanwhile, one has to wonder whether the base, S, and GTS versions of the current Boxster/Cayman are destined to become depreciation-proof used cars, in the same vein as the final air-cooled 911 models.
