Savvy with AMT (Automated Manual Transmission)

[faisal]

fuhyoo... sawy using magneti technology... couldnt believe it... they havent even built a proper reliable car and they wanna come up with such complicated gadgets...

jz do a proper simple car will do la... why want so much gadgets where they fail after few months??...

The AMT system has been available in renault cars for quite sometime and has been proven to work. It's only complicated to people who don't undertand technology.

Actually it is the other way round. Unless your definition of sluggish is different from mine. There has been constant complaints from road tester about the lag that happens when you shift gears on Smarts. It is like shift, pauses....., then it engages the next gear. Which is more apparent if you are heavy on the throttle. This is less apparent if you remove your foot off the pedal when you shift, but the some argue that this is stupid because it is supposed to be automated hence it should sort itself out properly.

Having driven the AMT, I can tell you that it is quite adaptive for easy lazy light throttle application and for go-faster-full-throttle applications.

While on an easy Manual mode with light throttle, the shifts are pretty ok, with no jerk and lurch, as I was lifting gently on upshifts. For flat-out shifts i kept my foot down and moved the lever. not race car quick but better than the Smart I drove.

In Auot mode it's pretty laid back in light throttle.

i believe u have a point in ur saying silvefish. in my knowledge, the Alfa's selespeed does jerk when left in auto mode.

from a different aspect, Honda City CVT also jerks in auto mode. better in manual.

The CVT also jerks? That's really odd. It's chain driven, should be as smooth as silk.

it's a good try by PROTON, but I'm expecting AMT available for higher rank vehicle in PROTON like Perdana, WAJA or new SGTI. Not practical to have it in small car like Savvy, unless PROTON wanna make the AMT pilot project start in small scale.

Most small cars are bought by city dwellers. So why isn't it practical in a small car such as the Savvy????

Most probly the driver was not keeping his foot steady on the throttle.

Apparently is it also cheaper to build than a conventional auto 'box. So I guess it is practical. Although I'd be pretty interested to know how the deal with Renault works. Heard Proton had to pay through their teeth in their dealings with Mitsubishi.

i'm still trying to imagine the coordination of gear work, upshifting frontpush, downshifting backpull the pedal. i think we can get more feel the other way around, i.e. frontpush for downshifting

depressing the accel when upshifting is also to be exercise as my coordination of right and left foot is gone (no clutch to press) i also imagine what my left foot will be doing, maybe left foot braking and right foot accel all the time.

maybe i better stop wondering and go to Proton Edar for a test drive, anybody wanna join me?

and somemore, if i buy this savvy then i can put magneti-marelli sticker without being an Ah-beng! hahah

I think in race applications it is the other way round (backpull up shift, frontpush down shift). ie. WRC cars and touring cars. At least, as far as I have noticed.

Hmmm...faisal, the R3 Exige 300RR has a sequential 'box, right. How's that one like?

The Hewland has full race sequential shifter. to engage first you push forward. then every upshift is pulled back. downshifts is forward.

The savvy is opposite. Personally I'd prefer to upshift by pillung back and downshift by pushing forward. BTCC like haha

Make sure you buy a Red car then. very Ferrari like with the Magnetti MArelli in white along the flanks. hahaha.

Letsee.... Rosso Red Savvy, R3 Bodykit, AMT, Magneti Marelli decals..... hehehe

Wonder how hard is it to rewire the thing to shift the other way around.

yeah and its also more ergonomic. when we are accelerating, our body is pushed backwards, so its only natural to push the gear lever back to upshift. while we are decelerating, our body is pushed forwards, so its eaisier (theoretically) to downshift by pushing the gear lever forward.

As you all know, the Proton Savvy models offered currently does not have an automatic transmission model. But what Proton is planning to offer to people who prefer the convenience of automatic in a Proton Savvy is not something usual. Normal automatic gearboxes are not liked very much by performance freaks because of it’s big power loss due to the torque converter, and lack of response to the throttle position and shift level changes.

The automatic variant of the Proton Savvy will be using something new which Proton likes to call a Automated-Manual Transmission, or Proton AMT for short. This gearbox is basically the Renault Quickshift5 gearbox, which is available in the Renault Clio. After all, the Proton Savvy was loosely based on the Clio.

The Renault Quickshift5 is a clutchless manual transmission gearbox. Yes, it works like a manual transmission with clutches and gears, not like an oil-driven automatic with a torque converter. No power loss there. It also has the speedy response of a manual transmission. All of that without the inconvenience of having to press a clutch, especially in traffic jams.

The Quickshift5, or Automated-Manual Transmission (AMT) as Proton likes to call it has 5 gears as you would expect from the name. There are 2 modes to it, a manual selection mode where you can switch through the gears sequentially by flicking the gear lever frontwards or backwards. The gearbox was derived from Renault’s normal 5 speed manual gearbox, but an electronic control module was added to it to operate the clutch electronically. The other mode is an automatic mode which shifts gears on it’s own and requires no intervention from the driver.

Because the clutch control is computerized with precised timing, shifts are much quicker than any average driver can ever attempt with a normal manual gearbox and foot-operated clutch. The result is a driving experience that’s zippy and fun. The computer features some form of fuzzy logic which allows the auto mode to adapt to your driving patterns.

Since the Quickshift5 is derived from a normal manual gearbox, it is lighter than an automatic gearbox thus improving fuel economy and performance.

too bad they launch it too late .
but good too , coz they used the time to refine it .

 

[suchap69]

anybody experienced quickshift5 before? is it also frontpush for upshift? maybe AMT shifting is in the reverse as the different in the driving position. europe - left hand drive, proton - right hand drive. just a theory, don't flame me arr, hahaha

rosso is red right? maybe Proton Rosso Savvy AMT R3, quite a handful already, and with the colour scheme of the R3..... this midget can be a striking mutha-K-car!

went to MTM forum and seems from the discussion there that no AMT is available yet for testdrive, even at thundercat platinum PE showroom in mutiara damansara, why proton so slow, wanna kill the rave and hype first? typical proton 'standard operation procedure' sigh....

Exactly. Why the hell they not make these things standard?

My Honda CF4 has AMT..It is convenient but only has 4 speed..
What I heard here, this tritronic gearbox has problem even in Honda cars
few years ago...maybe now it is ok already..

P2 good luck..

 

[si|verfish]

Mate, yours look like a auto 'box with manual override ie. tiptronic. It is not an AMT.

 

[faisal]

Hah I wish I knew.

Even BMW , with the 330i has a push-to-upshift in the normal car but in the 330i Sports it's pull-to-upshift.


And driving a car normally you'd pull to upshift to fourth and push to downshift to third (3rd and 4th being the mostly used gears when "spirited" driving).

 

[MK84]

If I'm not mistaken, SMG I is push to upshift. SMG II is pull to upshift.
