I guess 1.5TGDi will take another another 2 years or more to be ready ( read 3-5 years to mature ) and they are already on their path to electrification. They should then either go for plugin hybrid or BEV. To me, it doesn't make sense for them to continue the current roadmap of 1.5TGDi - they should skip that in favour for hybrid/ electric.

Off course JLR can land a helping hand to TML for TGDi development but when one want to downscale the current JLR engines for harrier/safari (a cost sensitive segment) then things are not very easy to adopt new needs. It becoming a exercise as good as a new development this become more fuzzy and costlier to execute. That is my first hand experience working in TML long back.

Logical step for Tata. Key reasons could be:
1.) Tata engine department is prioritising 2.2 diesel engine modifications for more power, BS6 and new emission standards from Apr 2023.
2.) Removal of FCA engine is key to getting a 5 star rating.
3.) May be Tata observed some declining trends around XUV700 petrol and intal deliveries were just euphoria around 200 horses and in long run XUV700 petrol owners are pissed off low average and less range of car.
4.) A high fuel efficient engine would be of a low capacity which would be an insult to Harrier/Safari brand name.
5.) No matter how much effort and investment is put in developing petrol the sales proportion would still be heavily in favour of diesel.

This 1.5 L TP engine would make sense if Tata is developing a product in 4.3 meter CSUV category in which they lack presence currently. This interview snippet only referred to Harrier/Safari so technically they could be developing a 1.5 L TP engine.

I don't understand this unless they are planning to launch all-electric versions of both, Harrier and Safari.
Also, no petrol = no NCAP rating. Is it?

Could be true, a doctor whom I know with interest in cars, who also owns Hexa claims to have seen Harrier Petrol with battery (mild hybrid maybe) at one of the service centers being tested.

This claim was more than 6 months back, so maybe the technology they want is not their yet and hence not on priority, or maybe the project is shelved altogether and starting afresh with something new.

I would trust this person as he currently owns more than one TATA car and has well connected sources.

While speculations are on full fly, let me also guess

1.) A good Doctor saw a petrol variant with a battery
2.) They are already using Punch Powertrain DT1 DCT in the Altroz DCA

Hmmm, could it be that they will launch the Harrier with a 1.5L Gasoline paired to a Punch Powertrain "**DT2**" hybrid DCT and launch a hybrid car? Possible?

Tatas have to develop a 4 cyl engine - both NA and TC. The current 3 cyl are just about adequate in their smaller cars and even the Nexon. Even the TC is barely adequate. This is partly owing to their heavier cars which are required if you want good safety at present. With experience and better engineering weight can be reduced gradually keeping the same safety level. They make great chassis and bodies and interiors but the engine sucks. Looks like the two competing market requirements were safety (USP) and mileage. The mileage cannot be much less than Maruti and others (with lighter bodies) otherwise who would buy Tata cars only for safety!

Hence, they have underpowered engines with inadequate torque and to make things worse they have put gear ratios designed for high fuel efficiency. That makes the drivability of the cars even poorer. Too little torque in 3rd gear and 4th gear. Also, the engines vibrate a lot and are most noisy. They need a 4 cyl engine for the Nexon for sure otherwise it will fall by the wayside soon. There is going to be too much competition.

I believe it make sense to focus the time, efforts and money on something they can have a first mover advantage (EV space) rather than in investing in something (petrol engines) that will have low Return of Investment.

Also updating Tata's own diesel engine to current emission standards and introducing more 4WD variants in Safari/Harrier will be more beneficial in getting better market share/profitability than developing a 1.5 turbo petrol for a heavy SUV.

But Tata still need a 1.5L for other products that sits between Harrier and Nexon. Since the products itself will take few more years, it might not be a immediate need for them.

Tata Motors new TGDi engines: 1.2L and 1.5L

1.5 Liter engine delivering 170 PS will be sufficient for the Harrier. Will TATA deliver the Harrier in petrol or will it be reserved for the Sierra?

Anyway using an engine for just one model doesn't make sense for the company. Scaling up will help in economics and hence Sierra may get it at a lower power point maybe at 150 PS and Harrier at 170 PS.
