What is all this nonsense though about credibility and hybrid power, have any of you guys been following the WEC? Beyond that their hyper car has been equally humbled by the P1. Yeah great way to sell a new sports car model by saying its heritage is to be 3rd best at racing behind a Toyota and Audi and last in the hyper car battle. Epic.

People will buy the F type because it looks like sex and has an equally naughty exhaust sound. Porsche never chased silly Bhp numbers before so why on earth should they start chasing it now.

If there is one thing a niche model Cayman needs to be it is more exciting, more sexy than the current Cayman, a ruddy great heavy battery and 4 pot engine that sounds like a demented washing machine ain't going to cut it despite how "on message" some think it would be.

The point is that we have pretty much been told that Porsche is moving away from 6-cyl engines for the Cayman/Boxster. It is the direction of travel, whether or not we like it (and I do not). I am such a NA geek that I have spent the last few weeks persuading my wife that we should get a Mazda 3 over all of its tc competitors biggrin (It still sounds like a demented washing machine, but least one without an annoying turbo whine and flat power delivery).

Not a bad choice, I have a soft spot for Mazdas after the Mk3 MX-5 2.0 Sport Mrs NJH had for a few years.

The real acid test for hybrid power in a sports car is the BMW i8. I was surprised to see one on the road the other day, looked less outlandish than in pictures but one has to ask just what is the point in any sports car that doesn't have that whole driver excitement thing going on. The day Porsche finally loose that is the day I abandon any little respect that I have left over for the company.

As has already been mentioned, we already know they the Boxster/Caymans will be 4pots in the future and I would think a GT4 with a 4 cylinder engine would be a great chance for Porsche to get around the problem of making a "lesser" model that is faster than their "premium" model.

They've always avoided a more powerful Cayman as it would impact on the 911 sales, this way there is a clear distinction between a hot 4cylinder Cayman and the top end, traditional flat 6 911.

Hybrid technology may well creep in as well because that is the way cars are heading. I could like a light turbo'd 4 pot GT4 but start weighing it down with hybrid tech and it would loose any appeal to me.

So what if it was to be a small tough racer of the the 964RS ilk ... brimmed with motorsport intent and road legal, with a Cup version that's badder still ?

Who would want one ?

Should P choose to add Hibrid-ness, there's also a lot more room in the Cayman than in a 911 ...

But, I have a BMW i3 on order and it would be hard to square a track car with a city car --- though I have speculated on trailering the i3 to Oulton park smile !!

It would seem highly unlikely today, daft even and hard to imagine.

But, porsche could well build something like this, in fact some say they will have no choice.

IF the 919 wins Le Mans, suddenly the V4 hybrid will have credibility and be race proven. The new Mezger!

Porsche are the masters at marketing and will easily be able to 'sell' the concept. Its why they have returned to Le Mans.

The lack of hybrid means this will probably affect Cayman R residuals quite significantly? Then again it will most likely be PDK only.

Curious to find out the final power output of this.

More from motortrend (proper photos) -

I really like this, a touch smaller than the 991 GT3, perfect for the roads I drive.

Der Reifezustand des Porsche Cayman GT4-Erlkönigs lässt auf ein baldiges Debüt schließen. Denkbar wäre der Pariser Autosalon im Herbst.

Judging by the early-stage appearance of this prototype, it's unlikely that this model will be seen in final production form before the end of next year.
German site says it looks ready to launch in late 2014, Autocar says it is an early-stage appearance prototype. I think we will probably see it this year.

doubt it

the Cayman R is 40k now the GT4 will be 80k and will be 1 to 2years away, it's not going to make much odds to people with 40k to spend who wish to buy a true drivers car.

if the GT4 does have a 400bhp 3.8 and 6pots etc it will be even more than 80k once options are on it.

+1. The price of this is gonna be the slight problem.

I just received the latest copy of sport auto on my iPad and found this in the readers comments section...



he claims a coworker sent him the data for the latest GT4, recorded during ABS/ESP calibration runs.

371,6 PS on the dyno
404,3 Nm
1305 kg (without driver)

for a brief moment i hoped that would be power at the wheel.

According to some Cayman R dyno sheets the corrected power output after drive train loss would be ~452 PS. Rather unlikely.
Then I did some stty math (correct me if I am wrong) and the engine would have to hit peak power at 7900 rpm assuming the 404,3 Nm torque is correct.
The 991 GT3 has its peak power at 8250 rpm with 476 PS and 440 Nm. So in theory that would be possible.

But then a 1305kg GT4 with that kind of power — it would have to have a slightly detuned 991 GT3 engine — would have a far better power to weight ratio than the 991 GT3. That car would run circles around the 991 GT3 and would probably ruin its residuals too.

So the much more likely option is that these measurements are at the crank and the GT4 will be a rather lukewarm car (+30 PS and -40kg compared to the 981 GTS). IF the data is correct.

Can’t sleep, need to find a Spyder...

370 seems about right to keep it well away from a gt3

I est 380 ;-) , going to just be like the cayman R , now people will moan about the GT4 name.
Or they might just call it the R again.

I might be wrong, but don't those figures suggest a 3.6 NA engine? Too much torque for the 3.4?
