Rejoice, fans of the old flat-six powered Boxsters and Caymans! News is floating around of a more powerful 718 Boxster Spyder and Autocar received word that the drop-top will be featuring a naturally aspirated, flat six engine derived from the 911 GT3.

Yes, the same 911 GT3 that cranks out 493 hp and 338 lb-ft of torque. Of course we’re not expecting to see those numbers in the Spyder as Porsche is most likely going to have it de-tuned so that it won’t compete with its more expensive sibling. Perhaps an output of around 425-450 hp is within reason.

“Natural aspiration is one of our main USPs,” Andreas Preuninger, head of GT car development at Porsche told Autocar. “At Motorsport, we think we can achieve throttle response and immediacy a little bit better with an atmospheric high-revving engine than any kind of turbo.”

Though the flat-six Boxster Spyder’s specs remain hidden, we do know that the engine will be paired with a six-speed manual gearbox as standard with and optional dual-clutch, seven-speed PDK for the more track performance oriented customer.

On top of the new engine, the Spyder will be ditching a few creature comforts in order to reduce its overall weight. So say goodbye to air conditioning, cabin insulation, and the Boxster’s electric folding soft top. Owner’s will just have to take off and install the fabric top manually.

This is interesting. The turbo 4 gives fantastic acceleration - very useful in the real world (as opposed to the track). I wonder if this 718 Spyder will then actually be slower than the 718 S?

There are also quite reliable rumors that the Spyder will get the flat 4 turbo with around 385hp.
I would not bet money on a flat 6 n/a. engine. Using a slightly detuned GT3 engine is highly unlikely.

To be honest it is totaly unclear what engine will come.

After having the drive train out of a 718 I can pretty much tell you there is no room for a flat 6 in there.
Getting the exh and turbo out of the way might give a little room but I don't think its enough for the 6
Like the other poster stated it will more than likely be a higher HP flat 4.

There is a lot of power left in these little motors, Especially the S.
The turbo on the S is massive for the size motor its on. I want to say when I had one out and measured the compressor inlet it is around 52mm and the
turbine side is giant.

There is enough space for a naturally aspirated flat 6. Only turbo charged flat 6 will not fit.
The engine bay is the same size as in the 981.

After thinking about it I think your right.
With the turbo and related plumbing out of the way they should be able to squeeze the flat 6 in there.
If is a flat 6 most likely it will be a variation of the GT3 engine as the 911 motor is set up for turbo, But the internals could be changed to
accommodate NA
It will be interesting to see what Porsche does.

Now if you can fit a GT3 motor in there, Imagine a GT4 with the new GT3 RS motor coming with over 500hp.>:D

No way that this will happen.
Porsche is always protecting the 911 by holding down the Boxster/Cayman.

Look at the last GT4, only 385 horses and a standard engine. Spyder only 375hp.
Look at the 718, why do you think the 718 has got a 4 pot engine.....

Don't expect more that 400hp +- 10 for the next Spyder/GT4.
If we will see a GT4 RS maybe up to 430HP.

But no engine which is based on the GT3 engine. This engine is too good and too expensive.

why no skip the rear trunk, then there would be enough space for something fun :)

There isn't sufficient room for a turbocharged flat 6, but a normally aspirated flat 6 or turbocharged flat 4 gives plenty of scope for something fun & all without having to intrude into the rear trunk. Make no mistake Porsche could easily provide more performance than they actually will, even given the constraints of the current engine bay. However as "Acky" stated they've always chosen to protect the 911 & there's nothing to suggest anything will change on that front. Even the 3.8 litre/liter flat six in the previous generation 981 GT4 (which shares an identical engine bay to the 982/718) was slightly detuned for fitment to that vehicle, but they chose to restrict it to protect the power edge of the 991 Carrera S with which it shared the engine.

Anything that affected the balance of the car would be a huge mistake & there's simply no need to do so. If they altered the weight distribution to any great degree then I probably wouldn't want one anymore. I'll be honest I don't really like 911's & I certainly don't want a 718 with similar handling characteristics. Currently the main limiting factor of Cayman/Boxster performance is Porsche themselves, because they artificially & wrongly in my opinion insist on keeping the 911 at the top of the tree. I've never aspired to ownership of a 911 & I never will & the more like a 911 the Boxster/Cayman became the less I'd want to own one.

The Spyder is getting a flat 4 turbo and 390hp. I'm writing this because I know exactly as much as the author of this article. :nerd:

For me a 911 feels like a bus compared to Boxster/Cayman!
And for Power plant, based on the exhaust i say a 6 cylinder.

I'm pretty much on the same page regarding 911 handling & the Cayman's/Boxster's are now the true sports cars, at least against the less exotic versions of the 911 (The bus comparison is perhaps a little harsh though). As for the power plant in GT4's & Spyder's, I've no idea as there are always rumours & counter rumours so I guess I'll have to wait.......One other thing & I don't know if it's only for me, but the link provided didn't work. Anyone else have a problem?
