What happens to the AC at each signal? With each signal wait close to 5 min the reason to keep the engine on is not to be go ready but to keep the AC running. The AC cant run on the battery, it will drain it out quickly.

AFAIK, only the blower runs on battery. The compressor etc does NOT kick in when the engine is OFF.

Not sure how they will tackle this situation.

Exactly my apprehension. I never switch off the engine at red lights just cos need the AC running and in the scorching delhi heat its a must. This can be correctly answered by someone who will buy the car. So, lets wait for an owners review.

As far as I know Ciaz SVHS has idle stop, alternator management and gear shift indication which contributes to the claimed Fuel saving by Suzuki in legal cycle..... In this idle stop will be useful in city conditions.....however absence of AC under stop condition will be still felt. I hope Suzuki decides to offer ECO COOL function for hybrid variants in India....which will prolong the AC effect a little longer.

Mod Note : Please avoid typing with excessive dots.........like................this.

The start-stop system normally checks for a lot of conditions before deciding to either start or stop the engine. Some OEMs even check if the hood, door is open before starting the engine. As far as AC for a start stop system these are the possibilities
1.check if the cabin is at set temperature and if the cabin temperature deviates too much from the set temperature the system automatically restarts the engine to cool the cabin.
2.Use an air-conditioner that is capable of running of the battery (highly unlikely)
3.Use a Peltier cooler(used in car refrigerators) module to provide cool air during engine stop that runs of the battery.

So, there are lots of possibilities but we'll have to wait and see what Maruti have actually implemendted in their vehicles.

A little surprising ! Having used the Start-stop system in my Sumo, I am actually missing it now ( the Storme does not have it). The system is very convenient.

Eco-Cool was discussed briefly in this Team-Bhp thread (Maruti to introduce idling start/stop tech to increase fuel economy).

What Suzuki say about their "Eco-Cool" solution, not sure if it's the same as this solution from Denso.

I think its time for pure hybrids. The diesel engines are more expensive than the petrol counterparts, sometimes by a significant amount. With pure hybrids the price band of the petrol pure hybrid can be placed closer to the diesel sibling. The running cost economy can be matched (to a larger degree). You will also not hit the green tribunal deadline and in the long term there might be Govt policies promoting these.

Thanks RavenAvi for the information. Any idea why the ISG cannot be used during cold start up and why it needs a separate start up motor? Will it eat up the battery during the first starting cycle of the day?

It's nothing but the brake energy recuperation that disconnects the alternator when accelerating and only engages the alternator when braking/coasting to charge the batteries.

Vid, so if the ISG in the SHVS is actually helping the engine to couple up torque from the battery power during a demand situation, how will it disengage the alternator a.k.a ISG while accelerating? Sorry, but I am not getting the 2 in 1 concept.

Maruti launches Ciaz variants with added safety features

This is excellent move by Maruti, the market leader. It will set right example for other manufacturer's as well. This makes Ciaz more value for money now. Certainly Maruti has decided to take head on with Honda City

"Country's largest car maker Maruti Suzuki India today launched two new variants of its mid-sized sedan Ciaz, which come with additional safety features like dual airbags and ABS, priced at Rs 7.48 lakh and Rs 8.37 lakh (ex-showroom Delhi) respectively. The two new variants -- Vxi (O) and Vdi (O), come with features like Anti-lock braking system (ABS), seat belt pre-tensioner and force limiters and seat belt reminder with buzzer for driver side."

"By offering the option of more safety equipment on our base variants, we want to encourage customers to buy cars that enhance their safety," Maruti Suzuki India, Executive Director, Marketing & Sales, R S Kalsi said in a statement. Besides, all the features and attributes of Ciaz Vxi and Vdi, the "O" variants will be equipped with dual airbags, ABS and other safety features, he added. The Vxi and Vdi models of the Ciaz are currently priced at Rs 7.31 lakh and Rs 8.23 lakh respectively.

Can anyone please throw some light on the long term reliability and maintenance of this hybrid system,say after 4 years and 80000 kms on the odo? Will it have a better resale compared to the non hybrid version now discontinued?

Thanks!

Anyone got the delivery yet of this SHVS ? Hows the drive ? Any difference felt - specifically from starting up from red light ?

I was also looking for team-bhp review / add-on to existing review for this feature ...seems guys still have to get their hands on it.

For all those who have been waiting for the Ciaz SHVS review, here is some feedback, till the time TBHP official review comes out. Carwale has published the test drive report of Ciaz SHVS and it seems to be quite promising.

http://www.carwale.com/marutisuzuki-...reviews-20198/

Quote:
How does it drive?

The SHVS technology is limited to the diesel variants. The car gets a larger lead acid diesel battery that uses regenerative braking along with the regular alternator to charge. The bigger battery helps with the engine start-stop function and also assists the crank in generating the torque, thereby taking some load off the engine and in turn reducing the fuel consumption.

There are few prerequisites for the system to work – all the doors should be shut along with the bonnet, driver needs to wear the seat belt and like in all the start-stop systems, the ambient temperature of the cabin should be in check.

The start-stop function is effective; slot it in neutral, get off the clutch and the engine shuts off, depress the clutch pedal again and the engine comes alive almost instantly. The system is similar to the micro-hybrid used by Mahindra, only quicker. We tested the system in the Delhi traffic with an outside temperature of over 35 degrees, and it works really well. The car stopped frequently and the engine turned off every single time, and the moment we started again, the AC was effective enough to cool the cabin before the next halt. There is no reason to doubt that the Ciaz hybrid will be efficient, but we will wait for our efficiency runs to give us clarity. On the congested Delhi roads the car returned around 16kmpl.

The power figures haven’t changed, the 1.3-litre multijet still delivers 90bhp and 200Nm of torque. It feels the same to drive as well, only it probably slows down a little quicker on lift off with the regenerative braking.

In above article, they got 16 kmpl average...it is quite a drop from ARAI figures of 28!!
I was expecting atleast 20/21 in traffic, and around 25 in highway....maybe I am just too optimistic!!

It is a good move by Maruti but then how many of us in India care for environment? Heck, we don't even care for our own lives. I mean many consider airbags and ABS unnecessary. I remember Civic had a hybrid which did not take off. Prius did not succeed either, in India. Even in US, generally Hollywood celebrities are seen driving Priuses to Award functions, flaunting their green credentials. But they also have couple of V8s and V10s tucked away. Much more research than is at present, is required to get Hybrids accepted as everyday motoring car. The only successful hybrids we see in thousands is Scorpio micro-hybrid, but not sure how much of a hybrid it is.
