Porsche's New Engine: Flat-Four Under Develoment
Porsche’s planned “Baby Boxster” has been a divisive issue for fans of the Zuffenhausen brand: on the one hand it holds the promise of a pure, low-cost entry to the Porsche driving experience; on the other, it’s a neo-914, a Volkswagen first. And with VW and Audi versions planned as well, what on earth would be the point of Porsche offering a third version of a mid-mounted, inline-four-powered roadster? Luckily that’s not a problem Porsche will have to worry about, as the firm’s R&D boss has confirmed to Autocar that
We have a four-cylinder boxer engine under development.
Apparently the design being tested now is a 2.5 liter unit making as much as 360 HP with turbocharging… which means that this engine’s potential goes beyond merely the Bluesport-based Baby Boxster (please Porsche, give us something to call this car… and make it better than “Cajun”). Wolfgang Durheimer says that this engine “can” be used in either the Boxster or Cayman… but that’s not all. If gas prices (or government regulations) require it, the engine could power the return of the 912. According to Durheimer, the first purely Porsche-developed flat-four
could be applied if necessary to the 911. Our decision is, on the 911 side, we’ll stay with the flat [six]. But there are opportunities for the future.
And Durheimer’s probably not the only one who sees opportunities with this engine. From 914 restomods to “Powered by Porsche” WRXs, this engine could (if nothing else) become a favorite of well-heeled, eccentric tuner-nuts. And with Porsche’s recent emphasis on hybrids and corporate synergy getting a lot of the play, it’s heartening not only to see Porsche developing a new downsized engine, but also doing what it takes to make its entry level roadster a “real” Porsche.

- Jeff S If AM went away I would listen to FM but since it is insignificant in the cost to the car and in an emergency broadcast it is good to have. I agree with some of the others its another way to collect money with a subscription. AM is most likely to go away in the future but I will use AM as long as its around.
- BEPLA I think it's cool the way it is.If I had the money, time and space - I'd buy it, clean it up, and just do enough to get it running properly.Then take it to Cars and Coffee and park it next to all the newer Mustangs.
- Dave M. I suppose Jethro’s farm report comes via AM, but there’s a ton of alternative ways to get that info. Move forward people. Progress is never easy.
- BEPLA For anything but the base model, I'd rather have a pre-owned Polestar 2.

I’ve always felt that Posche should have developed a flat-8 engine rather than the V8s that are in the Panamera and Cayenne. Porsche does have racing heritage with the flat-8s with F1/908 engines they fielded. Flat 8 needs much more engine bay room, can be hard on a Front engine or Mid/rear eng configuration. Probably a better firing config , they can have single plane crank on a pancake?
I always thought it would be neat if Subaru made a mid or rear engine sports or touring car AWD of course. The Porsche folks might complain but it would be a neat halo car like the old SVX or XT
