This upgrade must have taken many months if not years in the R&D. It is just a coincidence that it is launched just after Windsor IMO.

MG is taking battery from the same supplier (Octillion Power systems) as Tata. So they would have known what MG was coming up with and hence planned their own change in parallel. Not a coincidence by any chance.

Its sheer playing with common man's money and time. Instead of coming up with a responsible statement about the issue in the public space, Tata Motor has the audacity to bring one more variant of the same. Such is the situation of law and order in our country. All the affected owners should come together and file a lawsuite against the culprit automaker.

My thoughts exactly. I cannot make myself buy another Tata EV just for their lethargic response to every niggle that one brings forth. I recently posted about some fault about my ice car in one of the threads and I got a call from the company to book an appointment for check up on priority.

No matter what new car or variant they launch TM really need to prove a lot. They are just raising an army of unsatisfied customers that will narrate the horror that is dealing with TM Service Centers sometimes.

In a choice between Nexon and Windsor it's the Nexon that wins for my use case but the moment I compare TATA Nexon and MG Windsor, I am forced to go for MG.

I really hope Octillion cells work magic for TM. I am waiting and watching.

I think Tata has not figured out its EV firmware. I don't think just cells or vendor that matter but things like BMS software etc are critical. Please tell me if you can do this confidently with any Tata EV! People dread to take them below 20% whereas all MG EVs will just cruise even after 0%. Just watch this video from 13:00 to 16:00.

May be the battery part but this update seem to include other changes like Panoramic sunroof, which takes time to implement.

Then what’s stopping Tata from giving a lifetime battery warranty like in Windsor ! It must be an unbeatable deal.

Isn't it just a matter of choosing what to display? They are showing it as 0% but there is a good reserve (may be 5-10%?). This is a good move from confidence/trust building perspective but doesn't look good on sales brochure as you are projecting a range less than what it actually is.

I think not. I am just talking about able to comfortably use the stated/advertised capacity regardless of additional reserve capacity. If Tata is stating 40kwh but we are only able to use 32kwh (80%) or 36kwh (90%) or thereabout confidently before fearing when HV critical alert would trigger, then its firmware problem in my opinion! Then Tata should show 32kwh as battery capacity and anything beyond 32kwh is reserve capacity (bonus)!

It will be naive to think it’s a coincidence. Surely you cannot be thinking that Tata finished its development and validation work just yesterday and have launched it thereafter. This has obviously been timed to be a direct response to what MG has done. Issue is with the timing, or rather on Tata’s insistence on being reactive instead of proactive. They had a massive first mover advantage in the EV space, but have totally squandered it by not taking initiative. Furthermore, this reactive approach leads to paying customers feeling cheated and leaves a bad taste in the mouth.

Tata has done wonderfully well till now by offering a range of affordable EV vehicles first in the country and have done their bit to promote the EV ecosystem in India. They are the Marketleaders for a reason.

Ofcourse there would always be someone like MG to shake up the market. We should feel happy that Tata has developed it's capability to the point where they are able to give Global EV makers a run for their money and are capable enough to respond.

Let's not be overly critical because of one Windsor. Just before that, Tata had the most comprehensive and VFM EV offerings. They have a great lineup to come soon.
More competition is only better for us.

Do we know when bookings will open for the 45KWh battery variants? Tata's website doesn't make a mention of it anywhere. We've been considering making an EV purchase for city use and occasional highway use about the RRR (Hyderabad). Have been considering the Punch EV till now, but this changes things. I really love the Nexon's driving position and looks, as compared to the Punch. I guess I can live with the raised flooring in the rear.

Panoramic sunroof is icing on the cake, it will make the rear seat feel more airy. The prices have also been formally corrected, the discounts are now officially incorporated into the ex showroom cost. Tata has responded to the MG Windsor in the best possible way. Too bad, it has again taken an MG to make Tata wake up from its slumber. It was exactly this way 8 months back when Tata had to start discounting the Nexon after MG cut the prices of ZS EV. A move proactive approach will be much appreciated.

I don't think that is correct. Curvv EV has same prismatic battery architecture for the 55kw variant. So tata is following s top down approach. Maybe within a year punch and Tiago will also move to this battery chemistry. Since there is no further space in these platforms for bigger batteries, changing the battery chemistry and upping range is the new way forward.

Minor nitpick. There is probably no change in chemistry. It is the packaging form factor that changes.

A bit of nitpick from my end, there is gravimetric energy density improvement by 8% so that is improvement (not change) of cell chemistry. So it is not all about form factor improvement, it is also about same weight of cell able to store more charge as well.

All companies are trying to work on this, CATL recently showcased the 205WH per kg battery - link

Tata has achieved 186 WH/Lit, I don't know how much it is when translated to kgs.

You mean the car can be used (it won't stall anymore) even if the error is displayed and the owner has to take it to service ASAP? Do you know if the car can be charged to 100% (several times over)? Or will it refuse to be charged and used normally? Perhaps refusing to charge beyond say 50% might force owners to visit a service center ASAP.
