We’ll start with the base Boxster, which should see its 3.4-liter flat-four making room for a turbocharged 2-liter unit producing 286 HP (290 PS) and a maximum torque of 295 lb-ft (400 Nm).
While outside the US and European markets the Porsche Macan is sold with an Audi-sourced 2-liter turbo (as a Macan 2.0T), the heart of the Boxster will be a Porsche-built flat four.
When it comes to the Boxster S, the 3.6-liter boxer at the middle of the car should make room for a 2.5-liter turbo churning out 360 HP (365 PS) and a peak torque of 347 lb-ft (470 Nm).
Porsche has patented a variable compression ratio system that will offer exceptional output and MPG numbers once implemented, and the wildest rumors out there indicate the system will be used on the engines mentioned above.
Not only will the tech gimmick improve the numbers, but it will also help Porsche engineers create a linear power delivery, one that would keep the powerplant’s character close to that of a naturally-aspirated one. You see, the facelift for the third-generation Boxster will be the first time when the sportscar uses turbo power.
