Tata.ev Expands BaaS to Its Entire EV Range: Nexon, Curvv, Sierra and Harrier Now Get BaaS Pricing From ₹8.99 Lakh

Tata.ev has extended its Battery-as-a-Service (BaaS) option to the Nexon.ev, Curvv.ev, Sierra.ev and Harrier.ev, so all six Tata electric cars can now be bought with the battery financed separately. Under BaaS, entry-variant prices start at ₹4.69 lakh (Tiago.ev) and go up to ₹14.49 lakh (Harrier.ev), which is ₹2.30 lakh to ₹7.30 lakh below the regular price. The battery is charged at ₹2.6/km to ₹5.9/km, based on Tata's assumed daily running and excluding charging.

What Tata Announced

On 28 September 2026, Tata Passenger Electric Mobility, the EV arm of Tata Motors Passenger Vehicles, widened its BaaS offer across the full Tata.ev line-up. Until now, BaaS was available only on the Tiago.ev and Punch.ev. The Nexon.ev, Curvv.ev, Sierra.ev and Harrier.ev have now been added.

Buying the car with the battery included remains available. BaaS is an alternative financing route, not a replacement. Tata.ev's Chief Commercial Officer Vivek Srivatsa said, as reported by Rushlane and NewsBytes, that buyers increasingly want flexibility in how they finance an EV, alongside a wider choice of vehicles.

Tata BaaS Prices, Model by Model

All prices below are entry-variant, ex-showroom figures as published by Autocar India on 28 September 2026. Usage cost is based on 60 km of daily running (44 km for the Tiago.ev) and excludes charging.

The Tiago.ev has the lowest BaaS entry price at ₹4.69 lakh. The Harrier.ev sees the biggest upfront reduction at ₹7.30 lakh.

If you followed the Punch.ev at its facelift launch, note that earlier coverage, including ours, quoted a BaaS price of ₹6.49 lakh. The sources reporting this expansion list ₹6.59 lakh for the 30 kWh entry variant, against a regular price of ₹9.79 lakh. We have not found an official explanation for the difference, so treat the current figures as the ones to check at your dealer.

How Tata's BaaS Works

Tata describes BaaS as a dual-loan finance product. Here is what that means in practice:

• The vehicle is financed through one loan account and the battery through a separate one.
• Tenures are flexible on both.
• The battery EMI depends on battery size, down payment and loan tenure.
• Tata.ev has partnered with several financiers. The names have not been listed in the coverage we found.
• The offer is for personal users and the listed prices apply to entry-level variants.

So the lower price is not a discount on the whole car. A portion of the battery cost has moved into a separate payment, and you still pay for it.

What the Numbers Include and Leave Out

The per-km figures are easy to misread, so here is what they cover.

• Not included: the electricity you use to charge, maintenance, repairs and other running costs.
• Not included in the listed prices: road tax, insurance, TCS and other statutory charges.
• Assumed usage: 60 km a day for five models and 44 km a day for the Tiago.ev. If you drive more or less, your actual battery cost will differ.

Who Should Look at BaaS

BaaS is a financing choice, so the right answer depends on your budget and driving pattern.

Reasons it may suit you

• You want the lowest possible upfront price or a smaller first loan.
• You prefer to see the vehicle and battery as two separate payments.
• Your daily running is at or below Tata's assumed figure.

Reasons to pause

• You drive well above 60 km a day, which raises the per-km battery cost.
• You want a single loan with one EMI to track.
• The final battery EMI, tenure and financier terms are not yet clear to you. Ask for these in writing before you decide.

Evfy's Take

Tata's table gives the headline saving in rupees, but two simple calculations show how the scheme is built. Both are Evfy's own arithmetic on Tata's published figures, not numbers Tata has stated.

1. The saving is a fairly steady share of the price. Across the range, the BaaS saving works out to roughly 33% to 37% of the regular price. The Nexon.ev sits highest at about 37%, while the Punch.ev is lowest at about 33%.

2. The saving is close to a per-kWh rate. Divide each saving by the battery size in the table and you land at roughly ₹10,700 to ₹12,100 per kWh for every model. It looks like one consistent battery valuation applied across six cars, rather than six separate deals.

3. What the usage cost means each month. At Tata's assumed running, the per-km rates work out to about ₹3,400 a month for the Tiago.ev (44 km a day), ₹4,700 for the Punch.ev, ₹7,900 for the Nexon.ev, ₹9,000 for the Curvv.ev, ₹9,900 for the Sierra.ev and ₹10,600 for the Harrier.ev (60 km a day, 30 days). These are implied figures, not quoted EMIs. Your actual battery EMI depends on tenure, down payment and the financier.

The practical point is that the larger the car, the bigger the upfront saving, but also the bigger the ongoing battery cost. Ask for the exact battery EMI before comparing.
