I don't think its a goof up from TML. Nowhere they have mentioned that the teaser is of Tiago or Altroz.

I still cant figure out Sierra's price placement in the Tata ev lineup, though.

Punch (sub 4) < Nexon (sub 4) < Curvv (4.3) < Harrier (4.6) < Avinya (4.3)

The 4.3 mtr Sierra might be placed above Nexon, at par with Curvv or maybe above Curvv and below Harrier.

There is going to be much overlapping, for sure.

Wonder if this https://www.instagram.com/p/CmFADDJj...on_share_sheetwas regarding Sierra. Also, there was a rumour regarding the new EVs being 4*4 compliant.

Maybe fair but are we expecting some new variant of the Tiago EV to be launched so soon that too and at an event that pitches 'A new age of electric'? It's unlikely to be anything other than the Altroz EV which has been speculated as arriving soon. We will see I suppose.

On another note here's the image that they seem to have used.

Maybe the Sierra will be the three row EV variant on the OmegaArc platform rather than the compact Alfa one. A bigger electric SUV to sit above both the Harrier & Safari. It's imperative that Tata continues to push upmarket and rise the desirability stakes if it needs to increase pricing power. Or the brand will be stuck in a rut like Maruti unable to have an impact on the higher segments.

The Harrier, Nexon EV, Safari have helped Tata push upmarket, but it shouldn't stop there. Mahindra has really aced this Thar, XUV700, Scorpion etc... makes it a very appealing badge.

With all the losses from PV and JLR and mediocre sales of 2.2L engine cars, they rightly chose to halt the performance tuning of 2.2L and keep it for the CV segment. When they can get a more reliable engine from their JV partner, it all makes up.

True that was downsized for 1.4Xeta, but refinement was really good. But gave less mileage due to weight issues.

Such practices are seen worldwide. Even low end cars from Mercedes Benz use engines from their own company Detroit Diesel, which power some Hyundai cars too.

Yes. When there is no car in the line up, what is the purpose of developing it. Secondly Financial constraints stopped all new development work at TML and only upgrades were done after PUNCH.

With increasing sales revenue and the fact that the EV arm got fresh investment from outside, hope Tata makes up for the lost time.
Sincerely, a former TML anorak.

Financial reasons!!

Hope they get onto full steam. They did announce that after getting investment for EV arm and hiving it off into a seperate company, now TML has money for ICE.

Pratap Bose had specifically mentioned that it's based on the ALFA platform.

Dont think 4.3 is good enough for three rows.

[DRPSREDDY]

As per TATA MOTORS Twitter handle, cars that will see the day of light are

Avinya concept
CURVV concept
Safari EV
Harrier EV
Tiago EV

Maybe we will also see Punch and Altroz EV Versions apart from a few Commercial EVs too.

Hope they will also show the 1.5L Revotron engine apart from other engines too

Any chance this will be a sedan, ie. Model 3 rival?

[ashutoshb]

Well, they did say there can be various top hats on the platform, we don't know yet whether they will go with the hatch-mpv-cross thingy first or the sedan. We will soon find out

My reply was to the statement that Tata had already done the engine development which Mahindra did post 2015-16.

TATAs have done it more earlier with the development of TATA TIAGO with the all aluminium 1.2L Revotron engine in 2012-13. They added a balancer shaft to make the engine vibrate less. Now the engines are more reliable than before. But Aluminium block engines vibrate a lot.But now after announcement of regulations, new engine development of all the companies have come to a hault. It is impossible to develop new engines but only refine the existing ones.

While Mahindra developed their engine range and are all set for the time till EVs take over, same can't be said for Tata. Ofcourse, financial problems were there and Tata really was in the dark for the first half the 2010 IMO, but it has to be said. Tata is really lagging behind their engines, which they are covering up with PR talk of leapfrogging to the BEV age. Same for the lack of AWD/4x4/BoF vehicles in their lineup.

Anyway, hoping that Tata would atleast showcase the 1.5l 4 cylinder petrol in the Auto Expo.

A manufacturer can surely have some sort of future plans for their model line-up. And it is a fact that Tata was confused for some time. JTP, Hexa BS6, Blackbird are a few examples. It is not as if Tata didn't even dream to launch any cars above the Tiago or Nexon.

You must have mistaken for Mercedes Benz using Renault engines in their cheaper cars currently. While Detroit Diesel is owned by Mercedes Benz, it is mostly big commercial engines. The ones used by Hyundai was from VM Motori(Italy), which was owned by Detroit Diesel at that time. Part of a collab by Merc, Mitsubishi and Hyundai in the early 2000s.

No PR talk here, they have really leapfrogged the competition in the EV game and are way ahead in the race.

There's no perfect manufacturer in India, each carry their own Achilles heel.

While Tata's powertrains might lag behind the competition, rest of them have their own flaws. Both Hyundai and maruti in positions 1& 2 lag behind in the safety game. It's been 7+ years of the baleno and the thing is still fragile as a Thali popadum. The same goes for their biggest sellers like the wagonR, alto, spresso, swift etc.

All of Tata's mainstream compact lineup have never skimped on things like safety or structural integrity since launch wether it's the Tiago, Tigor, Nexon, Altroz, Punch etc...

While I agree that they can do with much better powertrains, it also CES down to what manufacturers prioritize the most, and in Tata's case it's safety and the EV lineup.

My two cents, I believe Tata Motors has realized a long time ago that ICE development is not their forte and most manufacturers are way ahead of them, including Mahindra. Hence instead of investing into making better engines, strong hybrids, flex fuels etc, they have just jumped to the EV race, piggybacking on Tata Group's other divisions.

And honestly, there's nothing wrong in it! If you cannot match others in one department, its better to take a sharp exit and take the road less taken. At least you would emerge as a hero () and you'd save time and money!

While I agree that they can do with much better powertrains, it also CES down to what manufacturers prioritize the most, and in Tata's case it's safety and the EV lineup.

Better powertrains and Quality Control IMO, are as important safety features as a rigid body! A loose fuel tank or an engine that just doesn't react well to quick inputs is equally dangerous as a tincan Swift!

Also, Tata's active safety (crash prevention) is quite poor currently, and amongst the lowest in the industry! Hurts to say that the cars like the Nexon, Punch, Altroz, with best crash protection are amongst the worst in their segments in terms of crash prevention!
To be honest, I'd have loved if they launched a special edition with 6-airbags before providing ventilated seats etc in small cars like the Nexon!

Let's hope this Auto Expo, Tata would surprise us with cars that offer better engines, 6-airbags and better active safety features!
