Then what is the different between CVT and Super CVT?

[gregy]

As far as I know, CVT is used in the 1.4l Jazz for our market, while the
Super CVT is used in the newly launched 1.5l City. The only difference
that I can see, is that the Jazz's CVT doesn't come with preset ratios
unlike the City which has 7 that you can control at the wheel. Other than
that I don't think there's any other material difference, but please
correct me if I'm wrong.

gregy, sorry, the City 1.5l is using CVT, not Super CVT. So far, I found
Super CVT are used in 2.0l Toyota, namely Toyota Wish.

I notice that the power from the Super CVT is very close to the Super ECT
on both 2.0l engine. As compare this to 1.5l engine, power from CVT and
Super ECT is a very big different.

This is witnessed on Honda City vs Toyota Vios.

I don't know about the Honda CVT differences and it should be noted that
in Japan, they call it Multimatic S. I guess it is possible that Super
CVT would refer to the one with the 7-speed feature and CVT is just a
normal one with no Steermatic feature.

For Toyota's Super CVT, I understand that it has some new control
technology such as the neutral control which the forward clutch is
released while stopping in D for reducing the fuel consumption, the
control system for idling stop system, the low vehicle speed lock-up
control, the optimum ratio shift control based on power-train efficiency,
the optimization of belt clamping force control. The transmission may
operate in a manual selection range with steering-wheel-mounted push
buttons, allowing selection of six virtual ratios ranging from 2.396:
through 0.428:1. The CVT is combined with a final drive ratio of 5.182:1.
The transmission can, of course, be left alone to select ratios
automatically. It features hill-grade logic to provide engine braking
downhill.

Uncle Chips,

this mean much much high tech stuff loh...
hmmm must check it out at my friend T.Wish...to understand more on S-CVT..
: )

Happy Vesak everyone..!!


** maybe everyone are busy at temple now...

rx330,

How did you notice the power difference between the different gearboxes?
Manufacturers only give you their rated engine specs at the flywheel only
mah, how that power gets transmitted to the wheels is a different matter
loh. Please don't confuse yourself :)

For instance, the Jazz is supposed to clear the century sprint in 12
secs. How's that for a 1.4l auto? Perhaps we shall see what the Vios can
do, and how much of a difference in actual road performance against the
City before we conclude that the City is underpowered compared to the
Vios.

It's not about how much oomph you can get at the flywheel, it's how much
oomph that gets to the wheels that matters :)

gregy,

anyway juz wait for Vios launching loh then hv the chance to test drive it
and then can compare the power ...

'common sense' to detect downhill situations ....


This is for drivers without 'common sense' ?

Luckily my Unser is only with ECT (aka Ejeculation Control Technology) and
the 'common sense' is in my blain. Wait, let me check ...... ok, it's
still there.
