Porsche's new boxer / flat four-cylinder to come in three favors - 1.6 liter, 2.0 liter, and 2.5 liter motors
If this report from CAR is correct we are going to see three new four-cylinder engines from Porsche. They will be based on the same architecture but vary in displacement and output. The smallest engine will be a 1.6 liter with 210 horsepower. Next up, a 2.0 liter engine with 286 horsepower. The top of the line Porsche boxer four-cylinder will offer 2.5 liters of displacement and 360 horsepower (which this output certainly can be raised).
PorscheBoost originally reported based on early articles that displacement up to 2.5 liters was possible if the engine is a modular architecture based on the Porsche flat-6 engines. As these motors are all direct injected it certainly looks like Porsche is basing the design on the flat-6 to retain things such as the pistons and rods to keep costs down. Sharing the Carrera S bore x stroke means exactly 2.5 liters of displacement in a flat-4 configuration.
All three motors also will be turbocharged meaning a lot of fun for tuners. The question is, which cars will get these motors? The Cayman and Boxster are practically a certainty. This also means the flat-6 will be gone from the cars with three new four-cylinder engines taking the place of the six.
It will be interesting to see if the 911 gets any of these engines as well. The return of the four-cylinder 911? It's possible.

With either choice of motors I'm curious to how the engines will sound boosted and the revving capabilities. Will have to keep my ears and eyes open.

Should sound similar to a Subaru I would think.

What will be interesting is how they implement the 1.6L motor. Given that the 919 is using a 2.0L plus all the hybrid power-adders, it seems that they will use the 1.6L in a similar fashion. I just wonder whether they will allow the hybrid to outpace the 2.5L turbo.Current: '00 S2000
