Boxster vs Cayman - cabin noise

[Maxym]

Those of you who have experience of both 981/982/718 Boxsters and Caymans... Generally, is there any appreciable difference between the two as regards cabin noise (hood up in the Boxster)?

I'm tempted to replace my 981 CGTS with a Boxster 4.0 GTS. Am I likely to find the Boxster a markedly less civilised place to be, especially at speeds of 80 mph up?

I must admit, roof up, I actually find the Cayman louder than my Boxster. Not much in it though.

I went the other way, previously had a 981 Boxster and now have a 718 Cayman GTS.

Not much difference in noise, especially if the SoundAktor fuse falls out. Mainly tyre noise, especially on noisy road surfaces.

The main difference is that I found the Boxster a little dark and "closed in" with the roof up, as the rear window is small and the wind deflector and bulkhead are close behind your head. In the Cayman the bulkhead is lower and the rear window is larger and makes the car feel a little more spacious.

The rear boot is smaller on the Cayman though, as the Boxster rear boot opening is wider, making it easier to fit a golf bag with clubs in!

Have you always found it noisy?

The rear Pirelli PZeros on my 981 Boxster have become incredibly loud now they are half worn.

Loads off wind noise in Boxster when moving on.

According to a couple of independent reports I've seen, the Boxster is actually a tad quieter than the Cayman - and that, I'd expect was measured on smooth surfaces. On coarse concrete motorways the Cayman is pretty dire - but, anecdotally, the Boxster doesn't seem so bad.

I have a 6 month old 718 cayman gts, its a rattle filled nightmare at the moment (rattles on dash and in the rear boot area) and has been back for fixing, while i had it in i was given a 718 boxster gts, it seemed a lot quieter than the cayman over the same roads, tho it only had 500 miles on it and my cayman is already up to 3500. Both on pirellis.

Cabin noise and general nvmh is very poor on both in comparison to my previous evora 400, which is erm, disappointing.

That squares with my experience relative to Evora.

I have 3 friends who own or have recently owned Caymans and all have said they're a bit rattly/tinny. My Boxster 981 is pretty civilised, no issues with noise apart from tyres on some surfaces. Agree with an earlier post about the rear window being too small and making the interior a bit dark.

I have heard this criticism before, but I'm bound to conclude that it is, to a significant extent, related to wheel size and suspension choice. My 981 on 19" wheels and PASM was completely free of rattles. Tyre roar was a serious issue as I said, but the only severe NVH issue.

My 981C is slightly noisier than the Boxsters I've driven. But a lot of that is mechanical engine noise which is good to hear most of the time.

No rattles on 20's with PASM and feels solid, certainly not tinny.

Interesting. How do you define 'moving on'?

[Maxym]

Thanks for replies folks.

Possibly claustrophobic cabin is a good point.

I assumed the C and B rear luggage spaces were the same size. A little bigger in the B would be a bonus.

Interesting that an Evora would be a quieter place...

Thankfully by CGTS has only one occasional rattle in the rear. Somewhat shocked to hear that the problem could be much worse.

60 ish up you get wind leakage.

100mph a Boxsters quite loud.

The roof comes away from the top of the window and there is a lot of air leak at speed, no avoiding it once the roof expands to that bubble look it just lifts from the windows.

The road noise issue is down to the fact that the inner wheel arches have no felt type material to reduce noise. Our Macan inner arches are covered in felt but the cayman is just plastic. I assume it helps keep the weight down a little but I would forego that for a quieter cabin

[Porsche guy]

Running a daily 718 Boxster after a succession of Cayman 718's and to me the rear 3/4 view is a massive blind spot, also, there is no where to put any small item in the cabin, unlike the Cayman which has the sloping rear window which is handy for small bits and bobs-don't want to be going into the boot all the time.

The wind noise it far more pronounced in the Boxster.

Back to Caymans again soon.

Don't forget the Cayman has the large engine cover space. Ideal for laying out suits and dresses when going to a wedding, and the rear window still isn't obscured.

Did this recently driving my daughter to an interview, bloody brilliant.

I only mentioned the boot for any keen golfers thinking of swapping from a Boxster to a Cayman, as they may struggle to get clubs and bag into the Cayman boot, whereas a Boxster is fine.

Not a golfer either, but I would have thought that golf clubs would go fore and aft behind the seats if you removed the rear boot cover (simples!)

Here's the Cayman approach, & plenty of room in the frunk for the trolley..
