There’s a performance device called “dragy” that reportedly is very accurate. It’s $149.
I’d certainly like to measure my Tesla’s performance, (uncorked S75D), but once that’s done I don’t really feel a need to have that dragy device sitting years unused in a drawer.
So... What I propose is that we put together a bunch of similar minded people with various Teslas, buy one dragy, and then mail it around so we can each objectively test our car’s performance. We’d assemble everyone’s numbers then come up with real performance numbers.
The dragy is GPS based and communicates with iPhone or Android. It has been criticized because it uses a 10Hz GPS, the thought being that it cannot measure in increments of less than 0.1 second. I think it interpolates so may get accurate times closer to 1/100 sec. I’ve read that it is very close measuring 1/4 mile track times, the times closely match the track times on the printed performance tickets.
Anyway if there is interest, reply here, and if there are enough interested people maybe we can look into it further.
