With 140nm of low end torque and DCVT plus light weight, I anticipate this to drive better than Aruz and Myvi 1.5.

I beg to differ.
At this age of tech, turbo lag is very minimal because the ECU management and the small size of turbo is able to spool up quickly . This is not a drag car with huge ass turbo .

And... at 2400PM, the Myvi 1.5 will develop only 1/2 of its max rated torque, compared to turbos able to already develop max torque at low rpm right up to 4000RPM

For simple calculation - the Myvi's 2NR-VE torque is rated 143NM at 4200RPM
At 2400RPM its only doing 81.7NM. Try matching that with the 1KRVET.

Combine CVT management and turbo - if you were in the seat of your Myvi, be prepared to be smoked by the Activa at green light.

Secondly - as per your comment "D-CVT optimized for fuel consumption at high speed not like Toyota optimized for acceleration."

This is where CVT is optimized for either power or economy runs . Its a CVT for crying out loud. Continous Variable Transmission. This is where CVT reigns, no matter how much you CVT haters say it lags etc.
Your average Myvi 1.5 cant do just that with its 4AT slushbox (lets not dive into "Oh it can drag longer at gears or downshift")

In case you are not convince, lets take this video example. Proton CVT vs Myvi's slushbox.

Watch this video I shared earlier:
https://youtu.be/fVfR6LdJYsU

Or if you are lazy to watch a 5 minute video, skip to minute 2:54

It will show a representative of the RPM.
However bare in mind, this is a CVT. Its not fixed.

9.6 secs on the Toyota Raize AWD version vs Myvi 1.5L At 11.x seconds (based on few Youtube sources and including Wapcar own test).

What have you been smoking to say Ativa already lost to Myvi?

Secondly. Torque curve for all Turbos are linear. Don't generalise all NA non linear orque curve with turbos.
Otherwise why is turbo always quoted range I.e "2400-4000rpm" or "1500rpm - 4000rpm" vs NA always quotes as single reference.

Let's take example Nissan Almera 1.0L turbo. Similar RPM torque range as 1KRVET.
Yes I know. The almera has 12nm more torques than the Ativa. Again I'm here to show turbo torque band curve since we can't find any torque curve from Toyota even! Not even Pauline Tan has the photos during launch.



So pease stop trying to be a Myvi fanboy and try to thumb down a 1.0L turbo.

Appreciate you point out the error.
So looks like Ativa has 4nm more torques than the 2NRVE.

IF based on Axia /Bezza 1KRve engine it's around 650Rpm with aircond off and in Neutral gear.
so I expect this 1KRVET engine to be similar.

Wanna save petrol is it? it's already a 3 cylinder.

Hi Creations,
Probably I will answer this to my best ability - though I don't own a Ativa.
I drive an Exora Turbo. And I have OBD2 reader.

1) Turbos are not "off and on" switches. If one has a turbo boost gauge, one will notice the boost pressure varies. Or it will not boost at all, and drives like a normal NA engine. Depending on throttle pedal pressure.

But what I understand that Power button in Ativa possibility is to increase boost pressure limit (but not beyond specs), sharpen the throttle and adjust more aggressive CVT gear ratios (this one confirm). Hence better pickup.
Off = Lower Pressure = Lower horsepower but smoother ride. Probably improve FC.
On = Higher pressure = more horsepower .

2) I presume Ativa may not have turbo water cooling too. One have to check if there is any water piping going to the turbo.
In Exora, there is a electric water pump and the radiator fan will be triggered if temp is above 88C. Its there to protect the turbo and partially cool down the hot engine also.
Again, this is depending on engine cooling design.

Saw this on Youtube.
What if Perodua brought in a 1.2L N/A E-spec basic version. And price it lower than the X spec. Would it sell even with a manual? Yes they also have a Auto version too.
Price shown in this video is PHP 746000 = RM 61,823 = yes its same price as our X spec but could be lower, if Perodua price it right.
