Cayman or Boxster EV for you?

[Dresz981]

Well, I think physics might agree with him. EVs tend to be quieter than ICE cars. In a gasser, the engine noise is most of what you hear. In an EV, it's wind and road noise. Assuming they both have the same tires, aerodynamics are going to make the biggest difference. The hard top will give much smoother air flow, thus less noise.

That could make sense. However, I don't know that anyone outside of Porsche know the design differences between the variants. Some people believe the roof materials accounted for the differences in cabin noise levels. If this holds true in the EV versions then it's still plausible. I specifically mentioned past Boxsters because that's what's available for comparison right now.

The vast majority of posters in this thread would disagree with you:

I drove both, and absolutely never have i found the boxter quieter.

Sure, you hear the engine less in a Boxster, but not because its quieter, its because the road and wind noise are coming through the soft roof much harsher. And that argument can be made only for base cars.

If you jump into a spyder rs and a gt4rs, the spyder will blow your ears off compared to the gt4, with how much of the engine noise makes it straight into your ear

The boxter roof is not magic, its just fabric. On an electric car it will absolutely allow for the road noise and wind noise to be even mote pronounced than in the gas cars

I don't think anyone is comparing the cabin noise levels of ICE vs. EV. That would be silly. And you seem to be comparing apples to oranges in the ICE variants. Of course there will be more cabin noise in a Spyder vs. base Cayman. However, if you read/believe the posters in the thread I linked, there seems to be a difference in cabin noise levels based on the materials used in the construction of the roofs. It's very possible that a thin piece of sheet metal on a Cayman roof is less sound absorbent than the fabric material used on a Boxster roof. No?

Again, this is not my personal opinion. I've never driven a Cayman. I'm also not hell bent on the idea that the Cayman MUST be quieter in the cabin JUST because it has a hard top. Feel free to post some real world test results.

Cayman gt4rs is not a base cayman.

and in fact i compared base against base and spyder against gt4rs

I drove all of these cars personally, i don't need to believe anyone, because i have experienced it with my own ears

You seem to think that the cayman roof is bare metal for some reason. There is noise and heat insulation material in there, there is also Alcantara on top of that. Its multiple layers of material vs 1 layer of fabric on the boxter.

Not to mention that the 718 Cayman comes with noise and thermal treated glass for the back window, which further reduces noise compared to the boxter.

The boxter will absolutely not offer a quieter cabin than the hard roof version, ever. Its just physics.

I tried the "it's just physics" route, too. Didn't seem to have much traction...

Probably because it's not as simple as "just physics". If it was, someone would have already posted some actual test results to prove me wrong. The only problem with proving me wrong is I never stated I was right. I have not drawn a conclusion. I didn't come on here to prove anything. I've stated several times that I have never even driven a Cayman. However, I did post a link to a thread where the vast majority of people were stating, in there experiences, the Boxster's cabin was quieter than the Cayman's.

So what's my takeaway? Apparently I'm supposed to accept, "physics...now shut up and go away". Well guess what? I'm still stuck at square one: left wondering if there's a possibility that the interior cabin of the Boxster will be quieter than that of the Cayman.

And guess what? No one in this forum has the answer to that question...yet. Why? Because Porsche hasn't released that information. As far as we all know, there could be an extra layer of protection added to the Boxster's roof that prevents it from catching fire from being closely stowed near the HV battery. That extra layer could create additional soundproofing for the interior, thereby impacting the physics.

The bottom line: No one knows! And "physics" is not the answer when those same people don't know any of the science behind those physics.

Fair enough.

EV Caymen for us for aesthetics reasons, but not before a 2029 model. We got burned a bit with our first year Macan EV turbo. In the shop already 6 times (6 times for software but also four of those times also a phsycial component additionally needed to be replaced), ergo a total so far of 9 weeks at the dealership. Still love driving it, but it was made literally first month of manufacture, and as both JD Power and KBB say (paraphrasing here) “we do not care if it is a Rolls Royce or a Bentley, we advise significant caution in getting a first year of new model or the first year of a new generation.”

Good call. I just don't know if I have the patience to wait any longer. I have a 981 sitting in my garage that I haven't really driven since I purchased the Taycan. It feels so sluggish now.

My fingers are crossed that Porsche learned enough with the Taycan to make the 718 EV solid out the gate. I think I need to stalk some EV Macan and Cayenne forurms to learn how many first year hiccups they had before taking the plunge.

Do me a favor. Take a tshirt, a sponge, a piece of leather and a spoon and stack them together on top of your phone’s speaker, and hold them pressed down.

That's the hard roof.

Then take just a pair of jeans and press that layer against the speaker.

That's the soft roof.

Play max volume from your phone through both those layers. And there you go, you have a physics testing facility at home.

Let me know which one is louder It quite literarly is as simple as "it's physics".

A european house with multiple layers of insulation is also better insulated against noise than a japane traditional room with paper walls. Believe it or not, it's why they also stack multiple layers of materials on car glass windows, to make them more noise insulated.

Now let's put to rest this absolute nonsense of an argument and stay on topic.

Extremely oversimplified and now it's all about the roof? You are the only one who seems to be arguing here. I'm certainly not. I'm just waiting for you to show me something other than "take a tshirt, a sponge,..." to convince me that all of the other people with real world experiences are wrong. Can you please do that? If not, I digress.

"The Cayman is a loud car. The shape of the rear hatch area is purportedly an acoustic horn blasting exhaust and tire noise into the front of the cabin. Some have said that the Boxster’s cabin shape and insulated soft top make it slightly quieter.

I came from an M2 Competition, which is already louder than the normal 2-series, and I was unpleasantly surprised by how difficult it is to speak to your passenger at 70mph in the Cayman.

It seems that adding dampener/absorber in targeted areas (wheel wells, rear trunk floor, and doors), plus choosing quieter tires can make a significant difference."

"I owned a GT4 and the 981 Boxster S I still own at the same time. I drove them back-to-back on the same roads many times. PSE on both cars so exhaust differences were moot. The Boxster is much quieter compared to the Cayman body style for just the reason listed in the first sentence DriverDaily posted above.

I think the shape of the rear hatch area and big glass rear window and it's placement are the contributors, capturing and reflecting the road and engine/exhaust noise forward to the seating positions."
