mazda's activematic transmission

[marv0083]

guys I just want to know if kaano kalaki ang powerloss when u use activematic transmission compared to CVT, conventional automatic, and manual transmission ?

ive been trying to google it pero la makita

and another quick question

yung rx-8 diba activematic rin siya? is the mechanics of rx-8 activematic transmission the same with mz3's activematic

just wondering

[BlueBimmer]

afaik activematic is just the same as normal a/t except it has manual override..just a guess..

[marv0083]

so how much powerloss?

afaik 15% powerloss sa cvt paano sa conventional at manual

[BlueBimmer]

read somewhere mga 30% ata..malaki talaga..

[mbt]

"activematic" IS a conventional torque-converter automatic transmission. power loss will be the similar to any other conventional A/T, maybe around 15%

[marv0083]

wow close to a cvt ??? MBT

pansin ko pag activematic much responsive ang gear maybe my imagination hehe

[glntVR]

imagination mo lang siguro yun. When do you feel it ba? pag ikaw nagsshift o yung transmission?

[wilcats]

dpat tlga naglabas sila ng M/T na M3 :D

[mbt]

15%... 10%... 20%... it doesnt really matter hehe. hindi mo naman mararamdaman yan e. you won't be able to drive something and say, "this transmission has greater losses than the other one".

sa mga dyno tests sa US, parang lumalabas na 10% loss for manuals and around 15% for matics. although even those figures may be meaningless, since different dynos give different results, and the absolute power output will be influenced by ambient temperature and other conditions. bottom line, specs are secondary to the actual feel of driving the vehicle (unless youre racing, then the specs are secondary to a lap time hehe).

It would have been better if the Activematic shifts in 0.02 just like Audi's Pero our activematic shifts in 0.5secs. Hey, at least its faster than the Hyundai Tiburon's shifting..hahaha. (and so I've heard) And oh, at least our activematic doesnt shift at redline compared to its competitors.

here's the info for your tranny question marv

Sport AT

Any MAZDA3, MAZDA6 or RX-8 buyer who opts for an automatic transmission will get Mazda's Sport AT. 4-cylinder and rotary equipped models get a 4-speed Sport AT, while a 6-speed version gets connected to the MAZDA6 s' V6.

na fefeel ko ang shifting pag ako nag shift

sa CVT ng honda how fast does it shift for the sake of comparison lang

and also wat do you mean by doesnt shift at redline karding ?

[mazdamazda]

and also wat do you mean by doesnt shift at redline karding ?

when you reach the redline, it'll automatically shift to a higher gear.

AFAIK, activematics are completely conventional except for the manual shift option... which, in turn, makes them more expensive. But most manual-automatics are just novelties... after a while, you don't really care. I kinda liked the INVECs on my cousin's GSR when I borrowed it, but after about an hour, I didn't bother to shift anymore and left it in auto mode. Word is, it's the same with Honda's CVT. My relatives with the CVT City (already 3 in the extended family!) report that after a week, they don't even use the buttons anymore.

AFAIK, CVT is supposed to sap less power than conventional manu-matics and is supposed to be at par with manuals, but I just don't feel it. It shifts faster, true, which is why some CVT cars are as fast as manuals, but it doesn't get as much power down to the ground.

[marv0083]

maybe depende narin sa user akin kasi i really enjoyed using the activematic manual mode

[Karding]

Activematic IMHO, is for the people who still wants to feel the shift from time to time and for performance.

marv, CVT shifts continously. And dont worry, it cant shift on or near the redline because the use of CVT is for fuel economy not performance.

CVT is for convenience and economy. Thus, it doesnt reach near the redline. CVT isnt even shiftable, is it?!

A conventional CVT has an infinite (or a very large number) of gear ratios. It selects a ratio that can deliver to the wheels the power being demanded by the driver, but keeps the engine spin rate low within this constraint to improve economy and engine life. You can imagine that as the car picks up speed, the transmission continually shifts into a slightly higher gear. The result is that the pitch of the engine tone stays fairly constant and the acceleration falls off smoothly, instead of in steps, as the higher gear ratios have a smaller multiplying effect on the engine torque.

glntVR:

Imagination?! hahahahahaha. We, mazda3 owners, feel it at 0.5secs after we downshift or upshift. And its not an imagination.

marv, take your Mazda3 to redline, its fun! hahaha.

Earlier on 4-lane uphill, this Nissan Frontier wants to be an a55 and didnt want me to pass. At 60mph Im on 4th gear, downshifted to 2nd and right where the redline is, I shifted back up to 3rd then 4th...passed the Frontier with no sweat.

[marv0083]

ay activematic ka pala karding kala ko manual

anyway tama yun if u want to overtake in 4th gear hard shift 2 gears down

pero lets say pag nasa 30kph ka shift ka sa 1st gear then **** 2nd gear when it hits 50kph the power delivery is instant

Though true, but i'd still buy one which has the function that i will use only 5% of the time than not have it at all.

at PAR with manual tranny in terms of Fuel Economy perhaps. but currently its still slower in acceleration and quite alien in feel.

hi gents, i know this is alittle bit off-topic. since we'r discussing Mazda tranny's might as well share some ongoing development.
recently Mazda has made some upgrades to the Mazda6 tranny's in the States and in JPN.
[USDM Model]
1) Mazda 6 3.0li: 5AT to 6AT. (wonder how responsibly it shifts?)

[JDM Model]
2) Mazda 6 2.3Z: 5MT to 6MT (with carbon syncro's 1 to 3rd gear)
3) Mazda 6 2.3S: 4AT to 5MT (now equal to Accord :D )

when we can have those?

[mbt]

but remember though, an ordinary, conventional A/T (or the "activematic" left in D) WILL ALSO instantaneously (well, at least if the tranny is a good one hehehe) downshift when you punch the accelerator, even from 4th to 2nd if need be. don't get the idea that only by toggling buttons in "activematic" mode will you get this result. such "manumatic" overrides are most useful if the tranny is dumb, or if you're racing... other than those, medyo gimmick nalang yan (don't get me wrong though, gimmicks are usually fun while they last). hehe

with regard to a CVT, as far as i know, a CVT will also improve performance... or at least, it has the potential to... aside from also improving fuel economy. for one thing, shifts are continous, and you won't lose time shifting like you would in a true manual. in fact, with a CVT, you will get the quickest acceleration by leaving it in CVT mode. if you use manual overrides, like the gimmicky "7-speed" detents in the City CVT, acceleration should be slower.

come to think of it, "7-speed CVT" is a paradox hehehe.
