If like me you enjoy perusing the hand-written test results Car & Driver publishes in .pdf form; and also comparing real-world 718 performance data to its big-brother 911, then here's a pairing you'll find esp. fascinating...

The only data not contained in the track sheet is factory power rating:
991.1 Carrera S 400hp; 325lb./ft.
982 Boxster S 350hp; 309lb./ft.

Very very interesting!!!!!!!!! Thank you!!
I see a 0-60 mph of 3.5s for the 718BS. This is even lower than the 3.6s they announced. This is very fast!
We already know the 718 is more nimble than the 911C. From these numbers, can we reasonably conclude that it is about as fast as the 911C.
The more I read, the more I love this car. Can't wait to get mine (in two weeks CGTS)...

Have you done or do you intend to do any performance modifications on your Porsche?

It's nice to see real-world data. Very useful and reinforces (to me) that I made a good decision buying my Cayman.

I'm still sort of stunned that either a stock 911 or stock 718 will run a 1/4 mile around 12 seconds or less. I have no real interest in drag racing, but that's still really impressive.
The corner forces (G) on stock tires are impressive too.

I wish they had recorded the interior sound in the 911. Interior quietness is not a big deal to us. We have a new Honda if we want to ride around in a vault (plus several Brit roadsters if we want to be assaulted with mechanical noise :) ).
But our 718 is one of the noisier new coupes I've ever owned. I think a lot of the noise is tires. I wonder if a new 911 is quieter?

Do you realize you are comparing a 2012 911s with a 2017 718? A new 911s 0 to 60 time is around 3.2 or 3.3...the 718 is still impressive!

comparing a 2012 911s with a 2017 718
In this exercise I looked for nearly-exactly-matching performance profiles from cars with similar weight and PDK -- comparing like-to-like using detail test results from the same (unambiguous) testing methodology. Then one might draw some reasonable conclusions wrt relative power.

As a matter of fact the current base Carrera 991.2 also fits this same profile (with a touch more turbo-oomph -- and/or helpful gearing -- above 140mph)

But like its 9A2Bn turbo stable-mate 718, the 991.2 is factory-rated using the new, more-understated (IMO) turbo Porsche horsepower units. So I looked to the 'old-measure' 400hp 991.1 Carrera S as a yardstick for this closely-matched group.

eta: I have zero interest in drag-racing, performance mods or running Carreras off stoplights....my sole interest is to solve the engineering mystery of "how is this even possible?" when considering 9A2B4 performance relative to its factory-rating.

Is there a web address for more of those sheets?
Very interesting stuff there.
Yeah what a great resource. For the first time I felt fully confident in basing 'real-world power' estimates on actual raw source data (hand-written!).

I use the link in online C&D reviews (in grey box on right side of page) called 'Download Test Results'. Here are some others I've collected. Studying these you'll also note Porsche appear to understate GT series power (incl. Spyder) to a similar degree as turbos (I don't believe the 981 Spyder is anything like its rated 375hp....more like the 400hp of the 991.1 Carrera S 3.8 engine it shares). btw the manual transmission results show more variance for driver (shifting, launch control) I think.

eta: whoever at C&D decided "let's publish these track sheets in raw .pdf" gets my nomination for 2018 718Forum Award for Best Supporting Data In Comparative Analysis Of True Horsepower.

Thanks for that--a truly great resource.

BTW--I suppose it's also possible that Porsche is one of the only companies to TRULY state power:D--although that doesn't account for the C&D acceleration results that substantially beat Porsches figures.

Oh well, I guess I'll just have to put up a faster car than advertised.:(
