Tata Expands BaaS Across Six EVs: Nexon From ₹8.99 Lakh, Sierra From ₹11.99 Lakh
Tata’s expanded Battery-as-a-Service offering covers the Tiago, Punch, Nexon, Curvv, Sierra and Harrier EVs, with battery financing payable separately from the advertised vehicle price.
Tata.ev has expanded its Battery-as-a-Service (BaaS) financing option to the Nexon.ev, Curvv.ev, Sierra.ev and Harrier.ev, joining the Tiago.ev and Punch.ev. The move brings the arrangement to six electric models, spanning the brand’s entry-level hatchback and larger SUVs.
The advertised BaaS vehicle prices start at ₹4.69 lakh for the Tiago.ev and extend to ₹14.49 lakh for the Harrier.ev. However, these figures exclude the separately financed battery component. Buyers therefore need to consider both payments when assessing affordability.
The main change is how the purchase is financed: the battery remains a payable part of the vehicle’s overall cost.
Tata EV BaaS: Model-wise prices
Prices and battery capacities are reproduced from the supplied pricing chart. Regular prices are ex-showroom, pan-India. BaaS prices refer to the advertised vehicle component; battery financing and applicable additional charges remain payable. Terms and financier approval apply.
The Nexon.ev’s listed 45 kWh configuration moves below the ₹9 lakh mark for its BaaS vehicle component. The Curvv.ev and Sierra.ev enter the ₹10.99 lakh and ₹11.99 lakh brackets respectively, while the Harrier.ev starts at ₹14.49 lakh under the arrangement.
How much of the price moves into separate financing?
Subtracting the BaaS vehicle price from the regular price gives the following differences:
Model | Difference between listed regular and BaaS vehicle prices |
Tiago.ev | ₹2.30 lakh |
Punch.ev | ₹3.20 lakh |
Nexon.ev | ₹5.35 lakh |
Curvv.ev | ₹6.20 lakh |
Sierra.ev | ₹6.80 lakh |
Harrier.ev | ₹7.30 lakh |
These figures show the reduction in the advertised vehicle component when the battery is financed separately. They should not be interpreted as discounts or total ownership savings. The eventual amount paid depends on the financing agreement, including interest and tenure.
How Tata’s BaaS financing works
The pricing chart describes BaaS as a dual-loan finance product. Buyers must account for the vehicle financing obligation alongside the separate battery financing obligation.
The fine print states that battery EMI and indicative per-kilometre costs vary by model and battery pack. Calculations depend on the applicable battery price, loan amount, tenure and interest rate.
This distinction matters because a per-kilometre figure can appear similar to an electricity expense. Here, it represents an indicative battery financing or usage cost. It does not mean the car’s complete running cost is ₹2.60/km, ₹4.40/km or any of the other advertised figures.
Charging costs remain additional
Electricity used to charge the vehicle is excluded from the quoted battery figures.
The illustration also assumes daily usage of 60 km for most models and 44 km for the Tiago.ev. Buyers whose driving patterns differ should assess the actual monthly EMI in their quotation, rather than assume that the advertised rate is a bill charged solely on kilometres travelled.
The chart specifies that the offer is for personal users. Road tax, insurance, TCS and other government levies are excluded from the advertised prices.
What buyers should compare
A useful comparison between conventional financing and BaaS should include:
The total down payment across the vehicle and battery.
The combined monthly repayment.
Interest rates, loan tenures and processing charges.
The total amount payable over both loans.
Prepayment, foreclosure and outstanding-loan settlement terms when selling the vehicle.
A smaller advertised vehicle price can make an EV easier to consider, but the combined repayment determines its impact on the household budget.
Auto Punditz Take
Extending BaaS to six models gives Tata a wider range of advertised entry prices across its EV portfolio. In our view, this could bring more buyers into the consideration stage, particularly those comparing electric SUVs with similarly priced petrol or diesel vehicles.
The conversion from interest to purchase will depend on the financing quotation.
Buyers need a clear view of the vehicle EMI, battery EMI and charging expense together.
For Tata, the opportunity is to make the purchase structure more flexible. For customers, the deciding figure should be the complete cost over their intended ownership period, alongside the monthly payment they can comfortably manage.
