Recent rumors of a turbocharged, flat-four-engine from Porsche for the Boxster (pictured testing above), Cayman and maybe other models go back over a year. The latest scuttlebutt indicates that there could be three variants on the horizon with 1.6-, 2.0- and 2.5-liter displacements and power as high as 360 horsepower.

Car magazine in the UK claims to have access to the specifications for the project and thinks the 2.0- and 2.5-liter versions are guaranteed for production for the Boxster and Cayman. However, it believes a question mark still looms over the 210-hp 1.6L because the engine would go into a new, smaller sports car that still doesn't have a green light for production.

Regardless of displacement, the new fours would be turbocharged and direct-injected. The 2.0-liter would produce around 286 hp and 295 pound-feet of torque, and the 2.5-liter would make about 360 hp and 347 lb-ft. Earlier reports pegged some parts sharing with the current flat-six.

From a marketing standpoint, the flat-fours could be an easy sell. Porsche started out with four-cylinders in the 356, 912 and additional models, not to mention the inline-fours in the 944 and others. Remember, even its latest 919 Hybrid endurance racer uses a V4. The company isn't officially confirming the flat-four yet, though. "We don't comment on future product speculation," said Porsche spokesperson Nick Twork to Autoblog.

      Interesting. The big question is this: How much will they drop the prices on the flat-4 models of the Boxster/Cayman? A flat-4 Cayman going for, say, $40K would be quite appealing.

        I agree with UconnHuskies22. They will probably offer three models... which they already do now basically. The base, S, and GTS... and possibly a 4th, the GT4. The base and S may get the 4 cylinder engines.

        They won't drop the price, they'll raise it.

        It will be a premium engine and cost slightly more.

        Given the crappy exhaust note that is sure to accompany these engines they should give a discount. But they won't - they'll cost more. Hopefully this will give my flat 6 equipped Cayman a bump in resale down the road :-D

          Subaru H4s sound nicer than their inline-4 competitors... so...

      I think I'd prefer the six. I just drove a 911 and part of the thrill is the six.

      If they do this in the facelift, I am buying a current Cayman GTS or GT4. That is as good as they are going to get. There is no way I would pay $80K for a sports car with a four cylinder.

        Yeah, no way I would have taken a Lotus Esprit S4 back in the day.

      According to Panorama, the 4 cyl will be 13k LESS than the current Boxster. I'm sure the turbo won't, but I think this is a great move from Porsche and will make cars more available to everyone. It doesn't replace anything in the current line (yet) so what's not to like?

      Here I was expecting high horsepower from these being that it's Porsche who always goes a little farther..... I was highly expecting to see 450 horsepower from their turbo 2.0...... I mean, Mitsubishi sells a 2.0 with 440hp and a warranty. They have to out-gun minimally the 360hp from 2.0 in the A45 AMG benz. A base Evo makes 300 from 2.0.... These numbers are too low for Porsche. I'd venture to guess that the numbers would be more like this, if they are released at all.... 1.6: 275hp 2.0: 375hp (this beats Merc, and the outgoing flat-6) 2.5: 425hp (low enough for mass warranty, room for hi-po model at 500, not too close to 911 turbo) This is Porsche we're talking about here.... the numbers quoted are last-gen. They are always ahead of the curve. I think my numbers would be closer.

        I think Porsche isn't as interested in measuring their peen via specific output as you are. They don't have to out-gun the AMG motor any more than they have to outgun a Viper motor. They sell cars, not dyno graphs.

        You mention this is Porsche we are talking about. If you know anything about Porsche you will know historically they tend not to compete in the HP wars. Their cars are usually lower HP than their competitors, they just utilize that power better.

        I'm not sure what gave you the idea that they were about to make their entire Cayman/Boxster line up faster than their 911 line up...

        How much do you have to use the warranty in a 440hp 2L Evo?

      Of course, instead of bringing the Cayman/Boxster closer to the 911 Porsche will make it cheaper and weaker, and still charge an arm and a leg for it. Also, please note that this new smaller engine will not shave off a single pound of weight. The next Cayman/Boxster will likely be heavier and more expensive.

      I knew once Audi took over Porsche, they'd systematically pussify it. First, no more manual transmissions, now this.

        lack of manuals? Huh? People don't buy them anymore... Manual owner by the way. 30 years of driving manuals and I know that time is ending.

          The percentage of VW GTI's sold with a manual transmission is the same, or higher than it was 20 years ago. For your average "affordable" sporty car manuals are still selected a lot, more than you'd think.

      I smell Volkswagen engines … after all, they already use them in Cayenne and Panamera.

      "easy sell" LOL, you should browse a few Porsche owners forums before writing something like that.

        Sadly it appears a lot of Porsche owners on forums and off have selective memories about their great companies past. Personally, I greatly enjoy the fun and ability to modify the unloved 4 cylinder-ed Porsches

      Porsche in before Honda/Acura and Toyota/Lexus?

      Knowing Porsche they'll probably call it a Boxster Turbo and charge even more for it!

      I will not buy a 4 cyl. turbo anything. I love the 3.4L Cayman. It is on my bucket list.
