Usually, when we stop, we'll need to go from Gear 4 directly to gear 1 for manual rite??

In AMT, we can go straight from gear 4 to 1 to need to shift down 4,3,2,1??

for AMT
lets say u stop the car at traffic lights on 4th, it will automatically shift back to 1st....

but on the roll, u cannot go from 4th to 1st, got to do it in sequence ( 4th,3rd,2nd,1st)

its something like BMW's SMG... its like any other semi auto tranny
but this is from renault ?
if not mistaken its a manual with automated clutch which is useless..

Care to explain why being a manual with automated clutch is useless? The SMG is a manual with an automated clutch, so is that useless too? Automated clutch is not the same as an automatic transmission.

In very simple terms,

Manual = manual, with clutch and manually-operated clutch pedal

Auto = no clutch, uses hydraulic torque converter instead (a manual car doesn't have this)

AMT = exactly the same as manual but imagine you have a robot automating the clutch pedal for you

That's it.

The AMT in the Savvy uses the same technology as BMW's SMG, Ferrari's F1, Lamborghini's E-Gear and Alfa's Selespeed. Some Audis use a system called DSG, which is an AMT but it comes with two clutches (gives you the smoothness of an auto but the effciency of a manual. Very heavy though!).

It is totally different from the automatic gearbox found in any Mercedes (including the SLR!), Toyota, Honda or most other manufacturers, which use straight auto gearboxes (not manual) with a torque converter. Even Porsche's Tiptronic is an auto box, not AMT.

AMT is much better than auto in terms of efficiency. For those who say AMT is useless, all modern Rally and F1 cars use AMT (though of course more advanced).

It has been proven time and time again that the same driver can lap an AMT car faster around any circuit than the manual version of the same car (for example, the BMW M3, or the Ferrari 360), even when the weight and gearing is exactly the same.

But I still prefer manual though - more in touch with the mechanics of the car and more "fun".

AMT gives you the same degree of control, expect that you cannot shortshift (i.e. go from 2 to 4 or 3 to 5). Technically the gearbox is capable of shortshifting with no problem, but the implementation in production cars only goes up or down by one step so in practice you cannot do it.

ok i personally tested the Savvy AMT today - cool car. really liked it, especially when in the manual mode.

tend to feel some revving and stuff during gear change in auto mode, prefer manual mode cos the power more consistent.

i like the fact that i can switch to either auto / manual at any point of the drive. way cool

getting savvy goldries?

I think we can put the gear to neutral from any gear in AMT. Just flick the gear lever to either left or right.

But dunno leh cos I've never driven one..

quite likely. just don't know when. of course, i have to test out Myvi first but the Savvy is high on my list already.

yes.

just shove the gear to the left to switch between auto / manual ( ok la it' s not auto as in AT, but auto change gear for you). shove the gear to the right to neutral it.

driving just like manual la, hear the engine rev quite high already then time to switch gear.

haha... no need to waste time to test drive the other one la

what other one? today i've come to a conclusion that Myvi is not what i want - other than space that is.

1. the 1.3AT Myvi is known to be underpowered.
2. the 1.3AT Myvi is more expensive that 1.2 AMT Savvy
3. the manuals are out of my choice since i want something that's Auto
4. Savvy has nice FC but i've not heard that for 1.3AT Myvi

ok la lazy to list all - or else AT vs AMT discussion will become why i choose Savvy discussion.

btw the Savvy, i like the AMT manual mode best. feels like driving in NFS:MW cos i play all NFS games using manual. and even since NFS2, the gear shifts has always been sequential. so to me, it's not a problem - let's just hope i don't enter blacklist la.

i was reffering to myvi... hehe...

well u need to compare and see urself why is the hoohahype about some particular model.. does it really liveup to its reputatatin.

You need to change the gear to neutral when stopping ( ie. traffic lights) the transmission fault lamp will lit on as the transmission in D will keep searching for a correct gear even you pressing brake..it's unlike conventional auto you can stop in D.

If u press brake, it will automatically downshift for you...AMT is like brake-activated transmission system too where brake n the trans are related to each other.

Glad you will be choosing one..I know how u felt too when I first test drove many cars before settling down on Savvy...every type of car has its own personality just like humans.

i only bash Proton. not their cars. i find of all Proton Cars, the Savvy is probably the only one........well other than Waja, that's worth it's price.

anyway back to topic.

i'm still not sure how to explain AMT to people.

what i usually say is AMT is MT that works like AT minus stuff like the torque converter and such.

now the thing is, in Savvy it's not only clutchless-manual ie sequential gear-shifting without clutch - that part is easy to understand. now the part harder for me (to understand and to explain) is that it comes with automatic gear changes, does other AMT come with automatic gear changes? or is it just on Savvy?

people usually get confused at this point, it's like so it's an auto that's not an auto? heck even Proton SAs are still telling me AMT is auto auto auto....

possibly the easiest thing to say about it is that its an automatically-shifting transmission with a manual sequential ovveride function

so how would you respond when people hear the above bolded part and ask - "so doesn't that make it an auto already?"

Yes, all other AMTs or SMGs and Sequential gearboxes have an automatic function where you can put the gear into "D" and drive it like an automatic gearbox. You just have to watch enough Jeremy Clarkson videos to see how much he hates the D function as it is very jerky in urban driving on low gears.

must tell me where to download more Top Gear.

but really, i found the D function annoying myself. that also i only drove the car for less than 10 minutes.

LOL most of the time that category of questions usually come from people who are ignorant enough to be rated dumb blonds

possibly if the person really wants to know the lowdown on AMT transmissions, he/she should be rajin enough to research it on autozine or some other automotive engineering source.

sleepwalker - the one where he stalled the DB9 on a wharf?

now i understand bout savvy that use AMT transmission...n how bout naza bestari aka 206...it use tiptronic transmission...is it same mechanical bout only different name..???
