So in similar driving conditions, it will give 8.57kmpl, which is what I get if the car is driven with a heavy foot in traffic. Seems justifiable no?
ARAI ratings are way more complex than that. Read this highly informative thread:
http://www.team-bhp.com/forum/techni...ncy-tests.html (Article on how ARAI conducts its fuel-efficiency tests)

I would say that ARAI ratings only give a rough indication to compare expected real world FE of 2 cars. If Car A has significantly better (say +3 or + 4) ARAI rating than Car B, I would expect Car A to give better real FE most of the time for most of the people. But, if Car A has only slightly better ARAI rating than Car B, it is not guaranteed that Car A will also have a better real world FE. Cars can be tuned to perform better on the Indian Driving Cycle (IDC) that ARAI conducts.
If Ciaz hypothetically gives 57% of its ARAI rated FE in real world to a driver, it is not necessary that SX4 will also give 57% of its ARAI rated FE to that driver. Different engines, different power and torque curves.

The last 2 sentences in the linked thread above are very interesting, and indicate how these ratings should always be taken with a pinch of salt.

Quote:
Also, figures from the IDC may vary depending on which government approved testing centre is used — ARAI (Pune), VRDE (Ahmednagar) and iCAT (Manesar).

Some cars have shown huge improvements in fuel economy after the shift from BS III to BS IV which, rivals claim, could only have been achieved with a ‘champion' car, in other words, a car that has been tweaked purely for the test.

There is an option to switch off the hybrid system and use the car normally as any other car. This could be the go to option in highways.

I have personally test driven the car and it seems to work well.

The adaptation of Hybrids especially Prius is way too high in Europe and the US due to affordability. You see so many of them on the streets.

Here in India where the market is so price sensitive an expensive technology will never become commodity especially when the consumers has lot more cheaper options to choose from.

Have finally zeroed in on the ZDI+ variant ...got to book very soon, and would be getting delivery during Navratra's ...

Color choice - confusion between family members ..

Apart from normal accessories, whats the story with 3M detailing ? I have heard a lot about it - never got a chance to get any of my previous cars done. What is the exact package I have to refer to, and speak to 3M about (to retain shine and new like appearance ) ?

Ask for the paint sealant wash. Includes foam wash. Claying and polishing. Should keep the paint protected. I got my Ciaz done at 3M recently.

How much this package costs ? Hope the charges would be same across India - Chennai vs Gurgaon ?

What is the real world fuel efficiency for the Hybrid Ciaz ? Can it at least deliver 15-16 in traffic conditions ?

It was around 3.5k. In Chennai

Friends I have been hearing that Ciaz SHVS has better driveability than the earlier non SHVS version. Can someone who has extensively driven both the versions make out if really there is a substantial difference?

Better driveability means that the low end torque might have been improved. The peak torque of 200Nm is achieved @ 1750 rpm. Has the torque curve become more flat? I understand while accelerating there is some assistance form the battery, does this result in better driveability at low rpms, which helps mask the infamous turbo lag?

I have test driven both the versions, and I am going to book the vdi+ option next week. As I currently own Swift and have driven the Ertiga, I can say that the turbo lag is much reduced in Ciaz. Of course the lag is quite perceptible if you drive the likes of Figo aspire diesel or Honda city diesel back to back with Ciaz. You cannot match the performance of the aspire diesel either, with the Ciaz. But if you have driven swift and know how to keep the engine in the turbo zone, then you will love the Ciaz engine.

Between the earlier plain diesel and the SHVS version, I did't find much difference. I had driven the plain diesel version a while ago, so might need to drive both the versions back to back to find the difference. But I don't think there is a perceptible difference in the turbo lag. You can see the SHVS indicator turning on while accelerating, as well as when the foot is lifted from the accelerator. There must be some assist, but I think most of the FE improvement must come from the regenerative engine breaking, which takes the alternator load off while accelerating, when compared to that of a regular version.

WHats the theory with Turboo Cooldown ?
If I am driving on a highway for an hour, and suddenly face a traffic jam, which needs idleing, I'll have to be careful and do not put the car in neutral for a min or so (to avoid car turning off ) ?
If Maruti has added this feature, I think they also should have thought about turbo cooldown procedure ?

There is a detailed explanation on why we need to wait for a while before switching a turbocharged engine off, in the team bhp Tech Stuff area.

Oh yes, I know this thread, and I did located the same in Ciaz Owners Manual as well.

The point is, the technology present in SHVS is opposite of this belief - If I dont pay attention, and as soon as car comes to a stop, it would turn OFF as per design (within 3 seconds -not 10 seconds as claimed in some posts) ! Are we not hyping the turbo cooling to a large extent ?

I will get delivery of my vehicle next week. The first thing I am going to do is to turn off the stop start feature. I dilligently follow the turbo idling in my car. I dont want to cause the slightest damage to the turbo, whatsoever.

That said, the start stop feature is not only available in scorpio, is is also available in Passat as well. It must be in some other cars too, below 20L.

I am getting mine on 14th ...
Either I'll disable it, or would pay special attention to it !
What If I dont even cross 2K RPM mark - would Turbo still come into affect and idling rule applies ?
