Tata Motors Launches All New 1.2 Liter Revotron Petrol Engine

[Raja]

That is what I am saying -

85 PS is too low for a 1.2 turbo engine. Consider this friends:

Ecosport 1.0 turbo makes 125 PS.
Polo 1.2 turbo makes 105 PS.
Even the naturally aspirated Jazz 1.2 makes 90 PS.

If they were to retain the same 1.2 engine and give it a turbo, they could have extracted a lot more power from it and make it an awesome engine. If they are thinking economically, then as Raja said, they are anyways making a series of engines and they could have made a 0.8 engine with turbo and 85PS. That would have been more economical.

This current engine is neither very economical nor very powerful, when compared to the competition.

Raja - Irrespective of the future offerings, what I am trying to say it, the current engine's power does not match the displacement, especially when we consider its a turbo engine. So, either the outdated XETA engine is not capable of producing such power or the engineers at TATA are doing something wrong. Either ways, this engine is not something I would be excited about.

But bhp is not everything , check the torque and it's better then all other cars in its competition , leaving ford and VW .

The new micra active is detuned from 76ps to 68ps lower then figo, beat , I10 but offers more super drive ability , mileage and stress free city driving then the competition .

Honda engines are rev friendly but are pain to drive at times in city , and in city when and where do we get chance to rev the car to use it's full power ?

This engine is about drivability in city as well as highway plus decent mileage and tata is trying to hit a sweet spot .

Bhp suckers can wait , maybe tata thinks that .

There must be some product planning with regards to the engines they are planning wait and watch .

Let the engine come in the vista refresh and let the reviews come out milk and water will be dissected by its own .
One can't predict blindly if the engine is great or bad , it proves to be great or bad depending on how it is mated to the gear box , the weight of the car in which the engine is used .

Great thing is that tata becomes the first homegrown company to introduce a turbo charged engine after introducing the very capable and niggle free petrol motor of nano .

Good step in the right direction .

@ Raja & Raj_5004 : I think we will have to wait for the engine to be first installed in the car and then see how it performs rather than comparing the figures with other competitors. Because once it is installed in the car then only we can see how the stuff works out.

In a Turbo Charged engine irrespective if its a petrol or a diesel i feel it is the Torque which plays an important part rather the Horses. Ofcourse in a NA petrol engine you have to rev it hard to attain the power but in a turbo charged petrol car you achieve the power earlier and develops along the higher RPM.

Tata here has done this alteration on a mix of Performance and Better average.

I have driven the Polo TSI , Laura TSI and the Linea TJet. What i feel is the difference in these and the NA is that i get the power delivery pretty early and dont need to Rev it hard in a Turbo charged vehicle were as in a NA i will Revv it hard to attain that power.

Also the Figures are also a result of the kind of Turbo used by the company. The Ecosport and TSI use bigger Turbo setups where as Tata might be using a smaller Turbo.

Also one of the Biggest things is all the Turbo Charged petrol vehicle on sale in the Market at present are above 9 lacks so we have to wait and see on which vehicle does Tata put this engine how it performs and what will be the price of the car because if its lesser than these than surely it might be a worth buy.

But bhp is not everything , check the torque and it's better then all other cars in its competition , leaving ford and VW .

How can you compare the specifications of a turbo 1.2 engine to other NA engines? VW TSi and Ford Ecoboost engines leave the Revotron behind because they are turbo engines, much like the Revotron.

The new micra active is detuned from 76ps to 68ps lower then figo, beat , I10 but offers more super drive ability , mileage and stress free city driving then the competition .

That's highly subjective. I have not driven the Micra Active. There are a lot of factors playing here- weight, gear ratios, etc. But what we can compare here is specifications on paper.

This engine is about drivability in city as well as highway plus decent mileage and tata is trying to hit a sweet spot.

Who is denying that brother? But what I am saying here is simple -

A 1.2 turbo engine is capable of much more than 85 PS/14.3 kgm. If not, I wont consider that engine as "revolutionary".

Bhp suckers can wait , maybe tata thinks that.

If TATA does not want to offer bhp, then why turbocharge the engine and spoil the drivability of the car? A NA engine would have been a better choice IMO.

There must be some product planning with regards to the engines they are planning wait and watch.

Again, I am not denying that. Let's wait and watch.

If they launch the same 1.2 turbo engine with 100+ bhp, I will clap. If they launch a 1.6 turbo engine with 95 bhp, I will slap.

One can't predict blindly if the engine is great or bad , it proves to be great or bad depending on how it is mated to the gear box , the weight of the car in which the engine is used.

Hey, I am not saying its a bad engine. But TATA cars are not very light. So, come what may, a 85 PS engine in a Vista is not going to shake the world apart!

P.S.:

All I am saying is - from an engineering point of view, how is this a radical engine? We have seen amazing turbo petrol engines from Ford and VW. Revotron is a 1.2 turbo, yet it does not even make 100 bhp, forget 120. If economy was the sole criteria, that could have been achieved by a 0.8 turbo... that would have been a radical engine.

Anyways, as Sandy suggested, let this engine be driven first in a suitable car. Then we can decide how good or bad it is. Cheers.

Autocar did compare not I . Plus
Why not compare the on paper performance when they will be anyway compete with each other ?

That's highly subjective. I have not driven the Micra Active. There are a lot of factors playing here- weight, gear ratios, etc. But what we can compare here is specifications on paper.

Exactly so even more bhp or more torque such needs are also very subjective in nature . Someone primarily driving in city needs drivability in city which matters the most .

A 1.2 turbo engine is capable of much more than 85 PS/14.3 kgm. If not, I wont consider that engine as "revolutionary".

Revolutionary since it's a home made engine made by a Indian car maker , do you know any other home car maker who has developed any turbo engine ?

Again, I am not denying that. Let's wait and watch.

If they launch the same 1.2 turbo engine with 100+ bhp, I will clap. If they launch a 1.6 turbo engine with 95 bhp, I will slap.

Tata must have their plans lead , they will follow it as per a road map , in that case many will slap and clap .

Hey, I am not saying its a bad engine. But TATA cars are not very light. So, come what may, a 85 PS engine in a Vista is not going to shake the world apart!

Shake the world in what sense ? What must happen ?

Better is Wait and see , why to jump the horse now .

Assumption is the mother of all mess ups .

All I am saying is - from an engineering point of view, how is this a radical engine? We have seen amazing turbo petrol engines from Ford and VW. Revotron is a 1.2 turbo, yet it does not even make 100 bhp, forget 120. If economy was the sole criteria, that could have been achieved by a 0.8 turbo... that would have been a

.

How old is ford and VWs r&d d compared to tata ? And tatas engine will be lower in maintenance and price compared to VW and ford . Radical is a Indian maker who is not even 2 decades old have developed something on their own .

@ Raja & Raj_5004 : I think we will have to wait for the engine to be first installed in the car and then see how it performs rather than comparing the figures with other competitors. Because once it is installed in the car then only we can see how the stuff works out.

This is what iam saying , why to call the effort lackluster or great ? Let it roll in a car first and then it will be as clear as water .

In a Turbo Charged engine irrespective if its a petrol or a diesel i feel it is the Torque which plays an important part rather the Horses. Ofcourse in a NA petrol engine you have to rev it hard to attain the power but in a turbo charged petrol car you achieve the power earlier and develops along the higher RPM.

Tata here has done this alteration on a mix of Performance and Better average.

+100 this is what iam saying , it's not just the power which counts always it's also the torque . Because in city how often do we get chance to rev the engine ? We most of the time don't even reach that rpm level where the meaty powers starts .

So if one can get a good mix of drivability in city , decent high way performance , and decent mileage which tata engineers are claiming ( although it needs to be tested in a car ) what's wrong ?

I have driven the Polo TSI , Laura TSI and the Linea TJet. What i feel is the difference in these and the NA is that i get the power delivery pretty early and dont need to Rev it hard in a Turbo charged vehicle were as in a NA i will Revv it hard to attain that power

.

+100

Also the Figures are also a result of the kind of Turbo used by the company. The Ecosport and TSI use bigger Turbo setups where as Tata might be using a smaller Turbo

.
+100 , and in all honesty VW and ford are much ahead then tata when it comes to r&d and in all probability the turbo engine of tata will be less expensive to maintain then the TSI and ecoboost .

Also one of the Biggest things is all the Turbo Charged petrol vehicle on sale in the Market at present are above 9 lacks so we have to wait and see on which vehicle does Tata put this engine how it performs and what will be the price of the car because if its lesser than these than surely it might be a worth buy.

Exactly . And this is the reason iam suggesting wait and watch . Assuming and declaring things before hand is not wise .
Let the engine come in the refreshed vista and let's see how it performs and whether it's worth the penny or not . So simple .
Right now the effort needs to be applauded for being a first home made company to develop a turbo engine .

 

[vikyjoshi]

Why not compare the on paper performance when they will be anyway compete with each other ?

I guess this comparision will be required. Ecoboost is a great engine from ford but how many Ecoboost ES were sold? 31 out 143 on TAI alone? So its not only the engine that matters to the general buyer. Had it been on the turbo engine alone and the horses it has, probably I guess the number should have been around atleast 50% of the cars sold. However that is not the case.

Thus people not just run after BHP. If the over all drivability and fuel economy is good, I get good pickup the average person will opt for that car. Immaterial to the whether it is turbo or not.
If that is the case why are companies having NA engines. Who have stopped them for going for Turbo engines.
Atleast in the case of engines, I dont think there is exact apple to apple comparisions. Even Pears are compared as its the final output and value offering that an average buyer looks into.

 

[gaddambhargavareddy]

its just a further move from tata motors to grap few petrol cars buyers from their stable thats the reason they are opted this REVOTRON engine they already have several bad experiences with their old petrol power cars but they always put some effort to improve their cars issues and quality so we hope so that tata well managed to eliminate all those issues experienced in past and TATA said that they are extensively test revotron engines in INDIA,UK and KOREA with Technical support from JLR to gain maximum power and fuel economy.

So if REVOTRON engines are able give 21+ KMPL fuel economy means it will deffinately grabs some attention in petrol car buyers.

So I hope that REVOTRON engines are cost in manufacturing campare to other turbo charged petrol engines from other manufactures like Ford's Ecoboost,VW's TSI these engines are cost more due to their advanced technology thats the reason they are not able to price the turbo power cars competive in india each and every turbo petrol power car priced above 8.5lacks so at this price people not intrested to buy these cars still they are looking for lower price tag cars only.

If, TATA managed to price the Falcon4 Revotron(with 21+ KMPL) around 4.5lacks starting price for standard variant it will deffinately shake the market in B+ segment

 

[navnit013]

I think people should start treating TATA as a private entity and not a Govt/NPO.

Why is there a hope, every time TATA launch a new car, that TATA will slap a lowly priced sticker to its products. And when they have products with low price stickers on them, we expect it to have a Rolls Roycesque quality.

 

[gaddambhargavareddy]

i think tata may launch REVOTRON powered TATA Venture to compete with Maruti EeCo

Re: Tata Motors introduces 1.2 Liter Revotron engine (water-cooled turbocharger )

@TAUREAN CZAR: Lot of efforts taken by me and my friend in trying to get out the future plans about the engines but the officials were very much quiet on the questions not related to the Engine launched.

The officials were asked if the engine was going to be used for the present set of tata cars but the reply was that if the engine is new so will the vehicle be a new one. Mostly they are going to launch it during the Delhi Autoexpo.
About the gearbox they did not confirm anything about the 6 speed gearbox but told that a new set-up is in progress to bring out the optimum power and performance from the other set of new engines. however the 1.2 Litre Turbocharged petrol which they launched have been mated with the present set of gear box being used in the present cars of Tata.

No word on the other engines that are going to be launched but there are sets of 3 & 4 Cylinder engines in lineup.

Tata is really struggling hard to change its present situation in the Petrol segment of vehicles.

Hey! I just scrambled over my pictures of the 2012 AUTOEXPO visit. And presto! I found evidence that, infact, is a six speed gear box made by TATA Motors.

It is compatible for both the 2.2 L and 3.0 L DiCOR /VariCOR engines and delivers 450 NM of Torque !!!
This gear box has been called G-85. It is compatible for Euro IV & V emission norms

This gear box has various layouts:
1. Semi Remote Shift
2. AMT (automated manual transmission)
3. Direct Shift

Can't believe it. It was displayed at the 21012 Auto expo. But no one remembers it.

Here is it....

 

[jithinmjose]

finally tata launches AMT. Want to see how it fares with 23kmpl milege of celerio petrol AMT.

Re: Tata Motors RELIEVED All New 3 cylinder Revotron 1.2NG Petrol Engine:

This is a new engine. Although the power is similar to the 4 cylinder Revotron, the torque is lower. But there was a turbocharged 110bhp version of this 3 cylinder engine in the Nexon SUV concept. If another cylinder is added to this engine, I think it will be the new 1.5l engine.
I am expecting new 1.5l and 1.05l diesel engines. There is a new 800cc diesel engine on display at the expo.

 

[gaddambhargavareddy]

Re: Tata Motors RELIEVED All New 3 cylinder Revotron 1.2NG Petrol Engine:

this new engine available in two stage tunes

1st one 85bhp and 115NM torque

2nd one 110bhp and 170NM torque

 

[jagrover]

Re: Tata Motors RELIEVED All New 3 cylinder Revotron 1.2NG Petrol Engine:

Also this one with 4 valves per cylinder and DOHC..
When will we get 1.2L 16V DOHC 4 cyl Turbocharged Revotron..????

Change the thread name to "revealed"

 

[350Z]

Tata Motors is kick-starting a unique experiential campaign called Revotron Lab to showcase this engine across India ahead of Bolt and Zest’s launch.

PS: In Mumbai, the first lab is being set up at the Infiniti Mall in Malad.
