Depends on which gear the vehicle is in. Higher gears will allow coasting with lesser braking effect, while lower ones will slow the car down quickly. When going down a flyover or even on a flat road for instance, coasting in 4th or even 5th with the foot off the throttle lever won't lose much momentum. Coasting in gear will also enable higher fuel efficiency than when coasting in neutral. I had once shot a 2-minute video of the Instantaneous fuel consumption on the MID and how it varies when the car (T-Jet) is coasting at different speeds in neutral, versus clutching, versus when coasting in gear. Will try to post it here sometime soon.

There is no harm, but doing this same deceleration with engine braking not only turns out to be more fuel efficient (and safer) than the neutral method, but also reduces the wear on the brake pads.

These days the way the engines are designed there's very less engine braking. In my experience with the Laura TSI (turbo petrol, like the Tjet) there's hardly any engine braking in gears 3 and above. At speeds like 40 to 60 pkh in 3rd, 60-100 kph in 4th there is absolutely no engine braking. And when you coast at these speeds in gear, you can check the instantaneous fuel cons on the MID. It shows zero, which is less than the idling fuel consumption. There's been a lot of discussion on this subject in this thread http://www.team-bhp.com/forum/techni...save-fuel.html (Does coasting save fuel?).

Coasting in neutral while approaching a turn is not a safe practice IMO. Its against the law in some countries!

Coasting with Engine engaged will let the engine run for little or no fuel. Thus, you are converting speed (instead of fuel) to engine sustenance. As a bonus, you also let the aircon compressor, alternator, HPS (Linea uses HPS, right?) unit all run off the excess speed you want to get rid off. Coasting in neutral means that car is bleeding speed only to the air (and wheel) resistance. Compressor, Engine, alternator, HPS unit all running off the petrol.
As an added bonus, engine is already engaged (and possibly in turbo zone), ready to propel you from the apex of the turn.

I know and i typically dont when the conditions prior to switching off are like that but with the T-Jet i have just got into this habit now consciously and will stick to it - anyway it takes me sometime to get the bag etc out of the car , collect other things...

Last efficiency update on my car was 11.45kmpl tankful to tankful method. 70:30 City:Highway use.

I have driven my T-Jet for around 100 KM and the MID shows 12.2 kmpl as the average consumption with 75% AC - pure Coimbatore city driving. Interestingly the instantaneous consumption says 6 kmpl under hard acceleration in lower gears and goes up to 32 kmpl when cruising in 5th gear with occasional gentle accelerator taps.

I have been driving a Swift Diesel over the last 5 years pretty aggressively and I drove my T-Jet in a very similar "not so sedate" fashion. Just to give you an idea, I was getting around 17 kmpl in my Swift.

Prior to Swift, I had a Siena 1.6 Petrol and I very rarely got anything more than 10 kmpl. Compared to Siena I feel that Linea is very efficient.

There seems to be a ridiculous amount of delay in T Jet delivery due to some production issues. If anyone can shed some light on this, it would be great. I have been waiting for 7 weeks or so now. I was promised mid of August delivery, now we are looking at mid of September!

Is the delay in delivery associated with any particular color?? As far as I know, they manufacture the different models in batches, with the T-Jet probably being given lesser priority than the faster selling MultiJets. Probably the color you asked for is sold out / out of stock, so you're put on the wait list until the next batch of T-Jets are getting ready. Just a guess.

That is exactly what I am hoping for too! According to them HH black is rare, so takes time. But more than 2 months of waiting is not very convincing for me.

I cant be sure, but I had read in an interview with FIAT India head that as of now they are making cars pretty much on order basis. Volumes are just too low to be piling up on inventory and their plant is running at very low capacity right now.

Overall, there may be some issue on the part of the dealer, which he is pawning off to FIAT. Do try and contact FIAT officials directly and try to find out the reason for delay.

I was able to peek into their ordering system. It looks like my car still in production, but I don't know how long it will take to get into transit. You're right, may be I can try calling FIAT directly.

If you have read my review , they did the same thing with me , i was promised delivery on a certain date and little while before they called and said Oceanic Blue is not being produced in the current batch etc and i will need to wait for an additional 15-20 days or something , escalated it within the dealership and also wrote to Fiat and in 2 days i had a confirmation that i will get it in time , got the sales/billing docket number and the car came on the day it was supposed to originally.

I have logged a complaint with the customer care. Hoping for a response from FIAT. Did you pull a different string in your case? If so, I would like to try that too.

No Different strings but i did have one strong thing working in my favor which was that i was the first person in the country to have booked a T-Jet and had also inaugurated the car - so PR wise it would have been quite sticky for fiat if i cancelled my booking - atleast i am assuming that this might have been the reason
