I did a little research and it seems the sorts of mettallic layers used for this block ~25db or more of signal. 6db is equivalent to twice as far to the tower so 25db is quite a bit. If you order front only you actually keep most of the cell reception in environments where there is a lot of...

Anecdotally the phone reception in my Taycan with the thermal/noise insulated glass is materially worse than in my wife’s without. I drop calls more often in marginal reception areas. I didn’t choose it for my Cayenne for that reason. I am in the US.

https://www.porsche.com/usa/models/cayenne/cayenne-range/ My predicted 324+- was pretty close, actual EPA range 325.

when Porsche does EPA testing, it’s not with a generic “Cayenne Turbo”, it’s with a specific config. The config they use for the coupe need not be otherwise matched - it could have more or less efficient tires and wheels for example. I think Porsche just has to say that it’s “representative” of...

Dug through and found coupes with Monroneys. 326 base / 316 S / 302 Turbo none have the most efficient wheels; we’ll see if they separately certify a range configuration of the coupe also.

Argh typo - the “u” is next to the “i”; meant to write

It seems that the turbos with either the standard wheels or the 21 inch aero wheels are rated at 303 rather than 298. it seems that the S with those wheels don’t yet have Monroney stickers available but u would bet they will be over 300 when they do show up. In fact my guess is they will be...

Ok I got it wrong. 298 for turbo, 299 for S, and 317 for base. mpge (city/highway) were 91/78, 91/81, and 96/84. looks like some cars in the inventory search have window stickers now. No coupes yet that I could find.

I am also curious about range on the Turbo. I had Claude build a detailed physics-based model fit to actual measured range that reflected the differences between WLTP range for the different wheels tires powertrains bodies etc. With limited data it’s a bit overfit but the same model on the...

The only OEM tire in the size for those wheels is the Pirelli PZero R

Since the base Porsche isn’t single motor I don’t trust this analysis. Of course the BMW is much cheaper and has some great attributes; the overall value is compelling, but the analysis itself is garbage.

There are two different widths of 22 inch wheels available and each comes with different tire widths. If you choose a specific wheel on the configurator, once it’s in your build there will be a little i in a circle next to the wheel you picked, and you can click on that and it will show wheel...

Your tires need to have a sufficient load index for the weight of the vehicle. Usually tires in the same size will have a similar load index but not always. They also need to fit the rim widths (which differ significantly front to rear) while having the same diameter front and rear. Unless you...

Not the same. EV has lower offsets and a larger difference between front and rear width.
