Porsche to “Downsize” with Four-cylinder Engines for Next Gen Boxster, Cayman

Porsche's new four-cylinder engine family will produce up to 395 hp
We’ve seen a number of mainstream and luxury car manufacturers downsize their engines over the past few years in an aim to boost fuel economy while maintaining performance. Companies like Ford have jumped on the bandwagon with its
, and even BMW has joined the fray by introducing a turbocharged,
2.0-liter four-cylinder engine
to replace its naturally aspirated 3.0-liter straight-six.
It now looks as though Porsche too has been bitten by the fuel efficiency bug, and will add a turbocharged four-cylinder engine to its next generation Boxster and Cayman.
“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,” said Porsche CEO Matthias Muller, in a recent interview with
Auto Motor und Sport
. “We will not separate ourselves from efforts to reduce CO2.”
The Boxster and Cayman currently use normally aspirated flat-six engines that range from 2.7 to 3.4 liters, and generate up to 330 hp (in GTS trim). However, Muller says that the new turbocharged four-cylinder engine family will produce up to 395 hp and we should see dramatic increases in low-end torque as well.

Seeing as how the mid-engine Boxster and Cayman are all about handling first and foremost, they will use a flat-four engine (which lowers the vehicle’s center of gravity) instead of a run-of-the-mill inline-four. The engine will also be based on the flat-six used in the 911, so both engines can share parts and production facilities.
Besides improving efficiency and lowering emissions, lower-end four-cylinder engines could help Porsche lower the price of entry for the Boxster. When the 986 Boxster was introduced in ’96, it was priced at just under $40,000. The current 981 Boxster starts at $50,400 (although good luck finding a stripper Boxster).

I see what you are saying, but I think we are getting into chicken and egg semantics here since all engine designs have tradeoff's built into their design. The biggest point is that advancements in overall technology improved efficiency in turbo and non-turbo engines, but advancements have also made turbo's much more drivable and reliable for mass usage. Forced induction cars have much more flexibility in achieving an output goal. That is particularly true when large displacement creates packaging, weight, or regulatory issues. The other way for NA engines to make power is to spin them faster but if you are above your peak torque then you are losing a lot to internal pumping losses in addition to the extra drag. Forced induction motors will always have the advantage of operating more closely to ideal volumetric efficiency and higher peak cylinder pressures.
Also, keep in mind the compressor wheel isn't the whole story. I feel that the turbine plumbing and packaging is still an area that has room to grow to use more of the waste heat that is usually blown or radiated away. For instance, a turbine driven alternator that ties in with a small hybrid battery. Just to pick a number out of the air... most cars could probably drive an extra turbine to 10-20 hp while losing 5 or less from exhaust restriction.
