I'm suprised they are using a flat 4 to be honest, is it definitely confirmed as a flat four? Makes more comercial sense to use both 2.0 and 2.5 engines from VAG which exist, are proven and suspiciously seem to have very similiar power outputs to the 2.0 and 2.5 that CAR have listed?
Low centre of gravity, brand values.I.e it's possibly there because it needs to be there not because they wanted to introduce it.

Never heard of 'serious' flaws with their engines, some seals can leak with a lack of use but that's about it.
Serious flaw to me would be throwing a rod or a piston ring prematurely failing.
Intermediate shaft bearing failure is pretty spectacular. Don't confuse that with leaking seals. Serious flaw to me would be throwing a rod or a piston ring prematurely failing.

If you go by what you read on the internet you'd think pretty much any engine Porsche put in a 996/997 is liable to go pop and write the car off at a moment's notice. Very impressive that the likes of Hartech have made a thriving business out of preventative maintenance for a problem that doesn't exist.FrankUnderwood said:

Actually quite a lot of people,
Brave souls, given the number of different Porsche engines that have had serious design flaws and lunched themselves even without added tuning... Serious flaw to me would be throwing a rod or a piston ring prematurely failing.

Frank - Take a look at the Porsche General forum - there's a reason why there are two 'major engine rebuild' stickies at the top. Far from infrequent - and yes, it happened to me too. Serious flaw to me would be throwing a rod or a piston ring prematurely failing.

Yes. Every single model, in fact 
but when a single model has been changed and downsized with turbocharging, the price hasn't gone down.
I meant AMG models. Eg does the A45 come in different engine sizes? but when a single model has been changed and downsized with turbocharging, the price hasn't gone down. E65Ross said:
No, but why does it have to be an AMG model? Eg bmw 3 series is a model, it comes with different engine sizes. The Cayman is a model, it comes with different engine sizes...
Because at least if you use the AMG model its more like comparing apples with apples isn't it.How many variants of a 3 series BMW are there, compared to 3 variants of a cayman?
But if you want to, are the smaller engines models of the BMW 3 series cheaper than the larger?

Irrelevant, because we're talking about models where the direct replacement has been shrunk and turbocharged. Using bmw M as an example... New M3/4/5/6 all use smaller engines than before, yet aren't cheaper.
If you liken the Cayman to purely AMG and M models.... Then you'll see that it's only porsche who use different engine capacities....

Actually quite a lot of people, happens to just about every other marque - look at the GTR as a prime example. Modded from new by a lot of people and warranty can still be maintained depending upon mods.
With other cars, especially certain brands, this might be OK. But Porsche is not what you would call "forthcoming" with regard to warranty issues. I personally believe that the 996/997 issues are blown out of proportion by internet fearmongering - but you never really know. Though I do feel the urge to modify my car to some extent for the sake of personalization, maintaining Porsche warranty is what allows me to sleep at night...FrankUnderwood said:

Bore scoring and intermediate shaft failure probably have to count as serious flaws. Serious flaw to me would be throwing a rod or a piston ring prematurely failing.

Are we? has that been confirmed?kambites said:
It would be astonishing if it wasn't the case. I don't see how Porsche could justify keeping the lower powered six-pot alongside the turbocharged four(s).
To be honest I'd be surprised as well, I only said 'if' the price was lowered it would even more appealing.I would like them to keep the 's' variant as a NA six cylinder though.
I'd guess (and it's a complete guess) that there will be a new entry level 981 with slightly more power from a four-pot at a slightly higher price than the old entry-level car and the S will be left as it is. Then the 982 or whatever it's called will be designed from the ground up only to take a four-pot. It's not what I want Porsche to do, but it's what I would do if I was Porsche.

You're probably right.I think we have to accept that there is a total shift from large capacity NA engines, and if Porsche do build a new Cayman/Boxster with the 4pot in mind I would like to think they would be one of the car companies that make a success of it.

Given that Porsche own one of the largest auto consortiums in the world who are possibly on the cusp of being able to sell a car with an e-boost system, I would say that there is a good chance that no one would complain about engine response between this and a 6 cylinder.
That would be nice. Reports of the death of lag have proven greatly exaggerated with every major advance in turbocharging technology, perhaps this time it might actually happen.kambites said:
