There's a lot of news coming out of Stuttgart these days, as Porsche->ke1 has revealed a multitude of new developments regarding its future engine lineup. One, in particular, that has gathered a lot of steam is the recent confirmation coming from CEO Matthias Mueller that both the Porsche Boxster->ke570 and Porsche Cayman are in line to receive a new 395-horsepower, four-cylinder engine.

Speaking with Auto Motor und Sport, Mueller the Porsche CEO specifically singled out the Boxster and the Cayman as two cars that will follow in this strategic downsizing of engines. Both models won't receive the same four-cylinder as the 919 Hybrid because that one was specially modified for that particular vehicle.

Instead, the Boxster and the Cayman are expected to receive a new four-cylinder boxer engine that will reflect the company's new engine direction, a strategy Mueller indicated was done to adhere to increasing industry practice of being more eco-friendly.

“We will not separate ourselves from efforts to reduce CO2,” the Porsche CEO said.

Mueller did not point to an exact number as far as the output that could be produced from these new four-cylinders, although he did say that the turbocharged engine could have in excess of 395 horsepower under its hood. That's a significant increase from the current 3.4-liter, normally aspirated six-cylinder that powers the Boxster and Cayman, good enough to hit "only" 335 horsepower.

This, combined with the new GTS versions of the Boxter and Cayman, point toward just how important these two models are in Porsche's future. These once-looked-down-upon models are primed to lead Porsche into the next generation of compact sports cars->ke506.

2015 Porsche Cayman GTS

The range-topping Cayman GTS still smells as fresh, and yet it's already proving to be a popular variant for the eight-year old Porsche model.

For the 2015 model year, Porsche has continued to update the car to keep it exciting, and it doesn’t appear to be slowing down. The range-topping GTS trim adds power, improves handling, and has decades of heritage under the 911 umbrella.

The GTS package adds more horsepower and torque to the 3.4-liter flat-six, driving it up to 340 horses and 280 pound-feet of torque. On top of that, the new GTS also comes with better handling, thanks to revised suspension components and the now-standard Sports Chrono package. It tops all of this goodness off with a unique look that sets it apart from lesser Cayman trim levels.
