Automatic Transmission Performance

Automatic Transmission Performance
I am very new to this site...and do not yet have an Rx-8. However, i will be buying one within the next few months with the automatic transmission. I was wondering what the 0-60 time of the Rx-8 is with the AT without any aftermarket products installed.
Thanks.
Thanks.

You can get good 0-60 times, low 7 seconds if you rev up to 3k or 4k rpm before releasing the brakes. But a standing start from idle will be close to 9 seconds since very little happens until 5K or 6K rpm.
I also recommend using the manual mode in light traffic, downshifting whenever you slow down, and prepare for accelleration in the lower gear, otherwise the Renesis will take a long time to shift and spool up again.

The published 0-60 time of the automatic rx8 in the pre-order book was 9.5 seconds or so. Granted, Mazda tested the 0-60 time for the 6spd at 6.6 seconds, but thats still a slow time.

rodmeister unlessthere is something very special about the automatic you ownthen theres no way you can rev up to 4000 or even 3000 RPM byjust holding on the brakes and reving. You canonly do that by setting itto neutral and then dropping it into drive whichis bad for the engine. By doingthe brake rev method the highest you can get the tachometer upto is between 2500or 2750 it doesnt evenmake it to 3000. The best youcan get w/brake rev is something in the high 7s. If someone could get to 60 in even7.6 seconds w/the automatic I would be very impressed. Fromall the times I have testedthis in my auto Rx8in addition to what Ihave read fromother auto Rx8 members posts youcannot get it allthe way up to 3000 RPM launch w/the brake rev.

I alsowanted to add that my automatic normally makes 0-60 in 8 seconds using the tiptronic mode w/o a brake rev. But that is only in tiptronic mode. If I trydont engage tiptronic mode then its definitely closer to 9 seconds. I believe this isdue to the factthat whenyou dont have it in tiptronic mode the car never gets close to redline and automatically shifts at or before 7000 RPM instead of reaching the automatic Rx8s peak horsepower at 7200 RPM. I amnot sure if the new PCM flashes correctsthis or not b/c I havent gotten the update yet. So if you dont engage tiptronic mode then itis likely that it will take aslong as 9 seconds to get to 60.

thanks for the info....now how fast would it be with aftermarket products such as a ram air intake, new exhaust, pulley's, air filter, muffler, or any other stuff you could add?

Thereare not too many people on here w/automatic Rx8s that have added aftermarket products like the ones you mentioned totheir cars. I think mikeb added aftermarket intake and exhaustto his automatic but I think he said that none of that did too much for his performance if anything atall.

Bummed, but bring on OU!
The brakes will hold just barely at ~3500 rpm for me. Stall speed does appear to be right around 3000. I wouldn't mind seeing times for a 4-4.5K stall torque converter. I don't know much about torque converters, though; would a higher stall speed affect performance anywhere other than from a stop?

I put my auto in manual mode, keep it in first gear and shift high when i want to get top speeds, you can get to 45 in ur first gear alone, Ive hit 75-95 in my third.... It depends how you shift in manny mode... automatic mode, I dont like how it shifts so quickly, but its not bad at all I estimate it being an 7.0-8 seconds and in manny u can get it in 6.5 or so... Its quick enough for me, and gives everyone whos been in the car a rush

i think buying the automatic then trying to make it go faster might not be a smart idea. first of all warrenty is an issue when you're messing around with the engine, and it's more money for not that much gain anyway. if you want an automatic, test drive it first, then see how you like it. if you don't like it i'd like to advise you to go for something else instead of adding aftermarket stuff to it? just my 2 cents, no

Here's an idea: if you are so concerned about the performance of the car, why not get the version of the car that comes with lots more horsepower and no slushbox? With the less powerful engine in the automatic, you're never going to be able to turn the car into any sort of drag racer.
If you just don't know how to drive a stick, LEARN. It isn't hard at all, and you'll be MUCH happier with the car.

jniamehr it soundslike youvenever driven in a car that can do 60 in 6.5 seconds b/c the automatic Rx8 is far faraway from feeling like anything close to that. Your estimatesare wayoff man sorry but Ive tested allof this before. The numbers aremuch higher than that you mustnot have ever had it timed. That rushyou are talking about is whatyou feel when you get over 5000 RPM and yesit feels great but unfortunately it takes a little while to get the tach upthere w/our automatics plus it goesaway rather quicklysince we can only get up to 7500.
therm8 did yousay that while holding thebrakes youve been able to rev allthe way to 3500? Thatpisses me off b/c mine can barely even get to 2500 likea lotof other auto owners on here.
