A flat 8 would sound very nice indeed.

Interesting but why develop another engine when they have V8s in the Porsche stable?

Yes, but it was a flat plane crank V8. Those sound good too. Regular multiplane V8's are a bit booorring.

If it's sitting mid-ships perhaps there's a packaging or weight issue?

Although like the previous poster, I suspect marketing reasons; to create a lineage to the Boxster, perhaps give an excuse to bump up the cylinder count in special 911s?

Because the flat 8 has history and it would be great to see it return woohoo

The other rumour is the engine being used in the 960 is the one already present in the 918. Then again there is also no confirmation of the 960 other than "there is space in the 458 / McLaren price range".

Lower centre of gravity and (like any boxer) perfect engine balance?

I thought the lower center of gravity was a bit of a dubious assertion. You still have to have the exhaust manifold under the car - raising the engine. A V8 has the crank (a heavy part) as low as possible with exhaust out the sides.

Saying that as much as I would like a flat 8! But who knows what they could develop. Knowing Porsche for their penchant for profits over engines that don't eat themselves or have other issues I fear they wont make a flat 8 or make one that is questionable in design. But, depending on the price point, maybe they could??? I'd like to believe they have a trick up their sleeves and have learned from previous problems.

Could be the new engine to power the bigger engined cars going forward. Would be a USP certainly these days.

If mid mounted it makes more sense as you then get a rear shelf, whereas a V8 you'd be struggling.

Yeah, all good speculation.

I can't help but feel Porsche wouldn't bother developing another engine, which would likely not find itself into any other car in the range.

I thought they were all about cost-cutting and platform sharing these days.

I just feel that a flat-8 wouldn't find it's way back into a rear engined car, due to the length and that would rule it out for the 'smaller' mid-engine cars, which won't be allowed to have a 'better' engine than their bigger brother.

The Spyder V8 seems like the most plausible engine to me but the Cayenne V8TT engine could also be used... Or an Audi derivative!?

Now, that doesn't rule out the fact that there maybe a Flat-8 in a car, used as a test bed, for a look-see. I'm sure it wouldn't have cost them that much to develop a one-off but re-tooling for a single application when they already have engines in-house and even more so in 'the family'. I'd love to see it happen but it just doesn't feel right.

Presumably because it would allow reuse of a lengthened/widened 981 chassis and is obviously a good packaging solution for the inevitable convertible?

That's possible but still doesn't explain why they wouldn't use a V8, which would be longer etc.

In fact, I guess the chassis would/ could be stiffer with the V8 and I did think Audi would share the platform and designing round a Flat-8 would mean the Audi engines may look 'funny' in there.

We'll see and I'd love to think they'd do a Flat-8 but I just don't see it - hoping to be proved wrong!

Of course they could paste on 2 extra cylinders to their current flat 6 there's no issue with that I think - so scratch the engineer a new engine bit I mentioned earlier. They would need to cast a new block and heads among other things.

What i was going to say was that engines may be getting shorter in sense because all the ancillaries are going electric. But I guess the same applies to a V8.

The Audi V8s are ridiculously short, 490mm front pulley to Bellhousing face. Porsche might well pick up and improve on this tech for a flat 8.

Given the price point, a new engine is probably essential.

But I have to say, it looks very very good ...

And what if they can drip feed this into the top of the 991 or future variants ?

The other elephant in the room is of course racing. If this is indeed to be the car to oppose the F458 on the road it remains possible that the 960 may be destined for Daytona, LeMans and suchlike. It is becoming increasingly apparent that a 4 litre 6 may not for much longer be a viable solution to compete evenly with the V8 and V10 engined Ferraris and Audis on the top tier of GT racing. Whatever they say in public I cannot believe that this subject hasn't been discussed at length in Stuttgart and one does wonder if the eventual replacement to the Mezger derived unit currently in use (now and for the next few years) might actually have 2 extra cylinders and my not be destined for a 911.

I was told with surprising certainty back in 2010 that when the next RSR arrived properly it would be a flat 8.
While its exactly what the racing needed (even then) it seemed a ridiculous suggestion.
Even now it still sounds out there but the two people who told me were certain and as you look at rumours, the group structure and the current motorsport competition its starting to look less so.

Hold on, Porsche back at Le Mans next year?

Would they use the 918 Rs Spyder engine or is this flat 8 the basis for the new power plant?
