991.2 and 992 GT3 and 3RS, make more peak power and more torque, slightly later, so worth revving out that bit more.
It's less that whether the torque peak is higher or not. the difference in torque between where the torque is at 7k (give or take a few hundred rpm after a gear change) and where the torque falls off to at rev limit is the issue....



There is less falloff at 9k in torque on the gt3 it seems at 370 Nm. The equivalent 260-ishlb-ft the 4rs graph shows is 350Nm. That lower amount at 9k relative where torque is around 7k rpm (~450 Nm) makes it worth short shifting in the 4rs compared to the gt3.

It seems GT4RS engine metallic sound between 8600 rpm and 9000 rpm is the most metallic sounding , even compared to GT3 991.2 and 992 GT3 & GT3RS

Is that so?
Yup is very noticeable in the car. I really dislike it. However it does have a big plus point on track in that you always instinctively know where you are in the rev range. Peak power is at 8400 and it tails off very quickly thereafter so it’s a good aural indicator of the perfect gear change point. There is no real benefit in reving it to 9000 unless it saves a gearshift. I think I have only hit the limiter once in 3 trackdays so far.
I like the metallic sound

That would be mine in guards red. We just collected it mid August. Are you going to Charles Hurst C&C at the end of the month or the 911 day at OPCB? We hope to be at both.

Beautiful weather in the Netherlands, stil running the car in, now 911km, that's an amazing coincidence :-)









What a car, what a drive.
Love the colour of your car. What is it? Brewster? Oak? Dark Olive? Am trying to work it out...

Spec not that far removed from one another, so how does 650 less miles equate to £105K difference ? or looking at it another way, each mile = £164 depreciation. Is it me or is that nuts?

Then again throw this into the mix...

1600 miles = £450K

...seems they making it up as they go along.

Well decision made. Which track toy to keep? R8 or RS?


In the end it was a very easy decision. The RS has gone and the R8 stays probably forever.

I really really wanted to love the RS but in the end I thought it was a poor car.

First the good points. On track and up to 9/10ths driving it’s immense, great power train, great brakes, feels unburstable. I think it looks great too especially in a bright colour, it’s a very Insta friendly car.

However the bad points. On the road it’s a dreadful car, truly bad. Tiring to drive and not pleasurable. The NVH is awful. Especially the induction noise, great for impressing 10 year old boys on an 10 minute drive and pants to live with day to day. But it’s not just the induction noise. After 3000 miles the whole car rattled and squeaked like an ancient Austin Maestro, worthy of special note are the funny plastic square bits fixed to the roll cage behind the headrests, no idea what they are for but they rattle the entire time, drives you bloody mad. It makes the whole car feel cheap and badly made. It’s a cacophony of evil noises on a drive round the M25 especially the concrete bits. My theory is that the induction noise is so loud to drown out all the rest of the noise so you don’t complain. The thing that gets me about the induction noise is that it’s not a nice inspiring noise it’s a tuneless blare, it doesn’t particularly add to the interactive experience of driving. It’s so unnecessary, the car would be way better if it was toned down by about 50%. I think that Porsche have misjudged this one, it’s like the were chasing a USP that the car really did not need.
As well as the NVH the very hard ride is a real downside, for me it’s just too stiff for fast road driving. On the bumpy stuff the car skips into wheel spin and hops about very easily. I didn’t drive mine in winter but my guess is that on Cup2’s in low temperatures the car will be a real handful.

At 10/10ths on the track it’s still a Cayman and that means it still can bite you hard. Ultimately just like all the rest of the cars on this platform sometimes when it releases grip from the rear it can snap out of line in an instant without warning and you have to be on your A game to catch it and avoid the pendulum effect on the way back. Here you go:

https://youtu.be/FZcNPr0EETc?si=-d_Y2HnKjVR38So-

Yes I know that the usual suspects will be along to tell me that I am chatting st and it’s just my bad driving but I have done many many track days in my R8 and in various generations of GT3 and none of those have shown the same characteristic. I love a car that moves around at the back, I really don’t like understeer, I like to steer with the throttle and balance the car at the limit. The R8 is sublime, it really is just a big old drift bus you can muller kerbs, turn in way to fast, and slide forever. It never ever snaps out of line. The RS on the other hand is generally very predictable and will slide around but just occasionally it has a little nibble. It’s that little nibble that I cannot be doing with.

As for the on track comparison it’s is incredibly close between the 2 cars. I did Oulton, Spa and Brands GP so a good selection and there is nothing in it for on track performance lap time wise. The most noticeable thing was that the R8 being heavier and more powerful can only do about 6 or 7 laps and then the tyre and brake temperatures go off the scale. The Porsche by comparison just goes on forever, well until it runs out of fuel! Which is quite quickly given it’s got a tank the size of an eggcup. The faster car on track was generally the one on new tyres. Both cars run near identically sized Cup2’s. My feeling is that the Audi would always be able to post a faster lap time as long as it was in perfect shape temperature wise but that over any decent stint length the Porsche would be quicker.

Very interesting to jump from one car to the other. The Porsche is actually the harder car to drive fast but the most rewarding, it’s quite a technical car but with great feedback. The Audi on the other hand is like a giant sledgehammer in a velvet glove, it’s a bit aloof by comparison but dear god it’s a great drift car.

At the end of 3 track days and 4000 miles I had no hesitation at all in keeping the R8 and selling the RS. For me the RS is just trying a bit too hard. I have not had a single pang of regret in selling the RS. I also cancelled the SRS, I think my time with the Porsche mid engined platform has come to an end.

Looking back at all the Caysters I have owned the best one of all is probably the Cayman R, very closely followed by the 718 Spyder. The R had the best mix of tactile and tangible characteristics and was a lovely all round car.

The best thing about owning the RS was that it has given me renewed enthusiasm for improving the R8 still further. I have got a load of ideas for going forwards into next year mainly about improving the brake cooling and brakes in general and also “tightening” the R8 up a bit. I don’t want to spoil it’s lovely on road manners but just get a little bit nearer to the feel of the RS on track. Happy days.

What a great honest write up, as for Cayman CR, 718 Spyder I personally think the 987 Spyder trumps both!

I entirely echo your comments about the 4RS when I got the chance to drive one for a few hours prior to purchase. On a track flat out all the time with a crash helmet on = excellent. For a road trip or Eurohoon = painful in every way with the NVH becoming far too intrusive.

The one I drove had similar handling to what you describe and the owner took it to CoG and they found that despite it being within Porsche tolerances , it was all over the place resulting in a poor handling you describe.........and they have had more than a few in for the same complaints !

I cancelled the purchase and have set my sights on another GT3 instead. Shame really but grateful for the test drive before committing to a car I would not have enjoyed. I do wonder if some of this is the reason there are quite a few nearly new ones for sale and the prices are dropping quicker than I would have thought.

Not well up on R8’s. Which is that and is it V8 or 10?

A mate has a gen1 R8 GT with the V10. It’s properly rapid. I have never driven it on track, but on road it’s lovely. Felt wide compared to the 996 turbo I had, but I could live with that. Had one of the nicest, part-throttle induction noises of any road car.

On wet A and B roads from Nurburgring into Belgium, there were times when my (mapped to 500hp) turbo just could not keep up. It’s a car I could warm to, for sure.
