Whoa! 40KMPL? If this is true Tata can add me on the list right away, I already own a Nano petrol and I love it, wouldn't mind a diesel one too.

I remember previously hearing that Bosch had developed the diesel engine for Nano. But not sure why ace engine is being used instead.

Do you know why this was changed?

Cylinder config please as ACE is single pod and Nano is parallel twin, good to have small twin diesel motor around as have plans to install in friends Diesel Bullet which is running Lamborghini 3.5HP diesel motor and vibrates a lot.

How can the motor be a DI? Its an indirect injection, in fact the Ace's diesel is a half cut version of Indica's 475 IDI diesel motor with 2 cylinders christened the 275 IDI.
Normal DI diesel motors are old school and extremely heavy for a lightweight car like the nano. Hope the reverse is true for the nano diesel.

40 kmpl translating into an effective 30kmpl for real life usage would be a big big game changer.

Move over Alto and team.

I do bet on the nano in the long run.

Ace engine is a twin cylinder. Half of Indica 4 pot.

It is more likely to be a CRDI engine. I do not think a normal DI engine would be able to comply with the current and to - be introduced emission norms.

As for the block itself, Tata would have taken the block and re-designed head and all the necessary assortments to make it a CRDI, or rather a DICOR in Tata-speak.

Would be interesting to see whether it gives more mileage with a decent pick-up. To think of it, it is almost 600 cc lesser than the current smallest diesel engine ( am I right on this?).

kindly note the starting thread, the BOSCH fuel system is CRDI,with 36 kW, I had seen the cross-section of the fuel section displayed an year back. They were trying to simplify few systems for cost reductions.
Must have near completion of trials and market launch.

there was a lot of buzz with statements from bosch et al stating that a tiny crdi unit was indeed under tests. if they're going for the ACE unit, it means the crdi unit didn't work out well. I'm certainly eager on a diesel nano. paint it in racing yellow for me please!

Oh My God! Diesel Bullet has Lombardini (made in India by Greaves) diesel engine.

I hope Ferruccio Lamborghini is dead. Otherwise he would have suicided right away.

A 4 seater car with 50km/l would be another feather in the hat for Tata! Hope that really comes true!

Are Lombardini and Lamborghini one and the same? I dont think so.

As far as I know, Lombardini is involved in farm equipments and the like. Correct me if I am wrong.

That would be a new world record. But realistically speaking we can expect 25 kpl city FE.

With Nano's weight and the diesel engine 50kmpl should be a possibility. It would be very close to a miracle if TML achieves it. The best way to do would be to invest (if not already invested) in a world class engine line - similar to the Ford's ecoboost and Hyundai's Nu. Now that is wishful thinking

It is an all new engine. Injection developed by Bosch and the engine developed by FEV.

the fuel consumption of 40kpl shouldn't be an issue. Even the discontinued Lupo 3l achieved an average of 42kpl with a much heavier kerb weight and a higher specific engine output. The ECO version of the new Lupo scheduled for 2012 is said to more than double that. The Nano is much lighter than the new Lupo, ahs got a lower specific power output and an engine with less internal friction. It should easily achieve it.
