Electric Vehicles (EVs) have always faced one glaring issue: sticker shock. While operating costs are significantly less than a petrol car, the initial purchase price is often 30-40% higher. This is primarily due to the lithium-ion battery, which in many cases can constitute upto 60% of the car’s price. This often puts off the average Indian Buyer from purchasing the car they want, and makes them instead consider an Internal Combustion Engine (ICE) vehicle.
However, in 2026, the EV industry has a solution to this problem: BaaS (Battery as a Service). In essence, this scheme offers a cheaper upfront price on the vehicle, and charges a certain amount of money per kilometer driven as the battery’s cost, hence decoupling the battery’s cost from the car itself. This allows the car’s price to reduce by upto ₹8 Lakh, making it either on par or cheaper than a petrol car of similar specification.
As of late-2026, all major car manufacturers in India offer a BaaS scheme. This article details every car with this scheme available in India, the financial math involved, and whether or not it is worth it for you.
Battery as a Service (BaaS): What it is, and how it works
Battery as a Service (often shortened to BaaS) works much like a cellphone contract. You buy the phone at a subsidized price, but pay a certain amount of money every month for the cellular network and data plan.
Likewise, under a BaaS scheme, you buy the car at a discounted price (the ex-showroom price is reduced by the approximate value of the battery, usually between ₹2.5 to 7.5 Lakh). You then pay a certain amount of money for every kilometer driven as a subscription to the battery. This amount is determined by the car and battery size, and is charged to you for the use of the battery, its warranty, and maintenance. The chassis and motor of the car are yours to keep, however. The battery itself is usually leased to you by either the manufacturer or a financing partner (Tata Motors Finance for Tata, and various banks for MG).
Many BaaS schemes have an option to buy the battery outright at any time, or transfer the lease to a new buyer (in case of resale). This effectively makes the car either a petrol or ICE one, depending on whether you bought the battery outright or transferred the lease.
The advantage of this scheme is obvious: it reduces the amount of money you have to pay upfront for the car, and allows you to ease into EV ownership without a huge financial commitment. However, it is important to determine whether or not a BaaS scheme makes financial sense for you. The answer to that question depends on how many kilometers you drive per year.
1. Tata Motors: The Pioneer Enters the Fray
Tata Motors, the country’s largest EV manufacturer, was the first to offer a BaaS scheme with the Tiago EV. In September of 2026, the company announced the launch of Battery as a Service for all of its electric cars. The company offers six different electric cars for sale with the BaaS scheme, ranging from entry-level hatchbacks to premium SUVs.
Model Battery Size Standard Price BaaS Price Battery Fee (per km) Upfront Saving
Tata Tiago EV 19 kWh ₹6,99,000 ₹4,69,000 ₹2.60 ₹2,30,000
Tata Punch EV 30 kWh ₹9,79,000 ₹6,59,000 ₹2.60 ₹3,20,000
Tata Nexon EV 45 kWh ₹14,34,000 ₹8,99,000 ₹4.40 ₹5,35,000
Tata Curvv EV 55 kWh ₹17,19,000 ₹10,99,000 ₹5.00 ₹6,20,000
Tata Sierra EV 63 kWh ₹18,79,000 ₹11,99,000 ₹5.50 ₹6,80,000
Tata Harrier EV 65 kWh ₹21,79,000 ₹14,49,000 ₹5.90 ₹7,30,000
Analysis:
Tata’s BaaS offering is arguably the most competitive on the market. The Tiago EV, Tata’s smallest and cheapest electric car, becomes the cheapest electric car in India at ₹4,69,000. This makes it more accessible to the common Indian buyer, and a great alternative to the petrol Maruti WagonR. It is ideal for first-time buyers, or commercial fleet owners looking to reduce capital expenditures.
The Nexon EV, India’s bestselling EV, sees its price reduced by over 5 Lakh, a significant amount. It now costs almost as much as a petrol Creta or Seltos, making it a viable alternative for those looking to buy an EV but on a tight budget. Meanwhile, the Harrier EV can be considered a direct competitor to the petrol Tucson and Grand iMiev, being an premium SUV that costs significantly less than its petrol counterparts.
Who should buy one?
First-time EV Owners: The BaaS reduces upfront costs significantly, and lowers the EMI (equated monthly instalment) significantly. This makes it ideal for first-time EV owners, or people buying their first car altogether.
Urban Car Commuters: Long-distance commuters will have to factor in the cost of the battery fee when determining if a BaaS is a good deal for them. However, for shorter, daily commutes, the reduced upfront cost and EMI will more than make up for it. The reduced range of the car is also less of a problem for city commuters.
Budget-conscious Buyers: The reduced ex-showroom price of most of Tata’s BaaS offerings means buyers can get a car within their budget. Particularly with the Tiago EV, which is the cheapest electric car in India, budget-conscious buyers will be able to get a lot of car for their money.
2. MG Motor India: The Windsor Revolution
MG Motor India has aggressively pursued the BaaS scheme, and launched several electric cars with it. The Windsor EV, India’s first electric MPV, was launched in late 2025, and specifically designed with a BaaS scheme in mind.
Model Battery Size Standard Price BaaS Price Battery Fee (per km) Upfront Saving
MG Comet EV 17.3 kWh ₹7,80,000 ₹4,99,000 ₹3.20 ₹2,81,000
MG Windsor EV 38 kWh ₹14,79,000 ₹9,99,000 ₹3.90 – ₹4.50 ₹4,80,000
MG ZS EV 50.3 kWh ₹17,99,000 ₹13,00,000 ₹4.50 ₹4,99,000
Windsor EV fees vary by variant and annual km driven.
Analysis:
The Windsor EV dominates proceedings in this segment, as it is arguably the most competitive car on the market. By cutting the price by over 4 Lakh, MG was able to position the Windsor as a direct competitor to the Maruti Ertiga and Toyota Innova Hycross, but with zero emissions. The Windsor also has a “battery swap” feature available in pilot cities, although the BaaS subscription includes regular charging as well.
The Comet, a popular city car, sees a significant price cut, and can now compete directly with the Tata Tiago EV. The reduced price and range make it ideal for city commuters, and an alternative to petrol cars at a significantly lower price-point.
Who should buy one?
Families: The Windsor EV’s most obvious appeal is its size. As a 5-seater MPV, it has ample space for a family of 5. It offers significant value over its petrol counterparts, and would be a great value proposition for families looking to buy their first EV.
City Commuters: The reduced range of the Comet is less of an issue for city commuters, who generally don’t travel far on a daily basis. The reduced ex-showroom price also means first-time buyers or those on a budget can afford it. It can also be considered an alternative to the petrol Mini Countryman, albeit at a significantly lower price.
3. Hyundai & Kia: The Premium Push
While Hyundai and Kia seem to be lagging slightly behind their rivals, both have released several electric cars with BaaS schemes in an attempt to compete with Tata and MG.
Model Battery Size Standard Price BaaS Price Battery Fee (per km) Upfront Saving
Hyundai Creta Electric 42 kWh ₹17,99,000 ₹10,99,000 ₹3.90 ₹7,00,000
Kia Carens Clavis EV 45 kWh ₹18,01,000 ₹12,84,000 ₹3.30 ₹5,17,000
Analysis:
The Hyundai Creta Electric sees the biggest absolute reduction in price of any car in India, at ₹7,00,000. This allows the Creta Electric to directly compete with petrol variants of its own petrol Creta and the Maruti Seltos, as well as the Kia Seltos and Carens. For buyers looking to buy an electric car but can’t afford the premium, this is a viable option.
The Kia Carens Clavis EV is a 7-seater minivan, and utilises a BaaS scheme to make itself more appealing to commercial buyers and large families. While it undercuts the Toyota Innova Hycross by a significant margin, the per km fee eats into profits for commercial operators.
Who should buy one?
Brand-loyal Buyers: For buyers looking to buy a Hyundai or Kia but are put off by the premium price of an electric car, this is a viable option. Particularly with the Creta Electric, which is a direct competitor to the petrol Seltos. With a BaaS scheme, it becomes much more accessible for those on a budget.
Commercial Operators: The Carens doesn’t see as big a price reduction as some of its competitors, but does see a significant reduction nonetheless. For commercial operators looking to cut costs, this reduction in ex-showroom price would be beneficial to their bottom line. However, the per km fee would eat into profits for larger mileage operators.
4. Maruti Suzuki & Toyota: The Late, But Heavy Hitters
India’s largest car manufacturer, Maruti Suzuki, announced its foray into the electric vehicle market with the e Vitara, and later followed it up with a BaaS scheme. Toyota followed suit with the Urban Cruiser Ebella (effectively a rebadged e Vitara)
Model Battery Size Standard Price BaaS Price Battery Fee (per km) Upfront Saving
Maruti e Vitara 35 kWh ₹15,99,000 ₹10,99,000 ₹3.99 – ₹4.39 ₹5,00,000
Toyota Urban Cruiser Ebella 35 kWh ₹15,60,000 ₹15,25,000 ₹4.99 ₹35,000
Toyota’s BaaS implementation has less of an impact on the ex-showroom price, but offers different warranty terms.
Analysi
The e Vitara is Maruti’s biggest bet at electric cars, and a significant reduction in price (almost 5 Lakh) makes it much more appealing to city commuters and first-time buyers. While there isn’t much differentiation on paper between the e Vitara and the MG Windsor EV, Maruti’s reputation for quality makes it a safer bet.
Toyota’s more conservative approach sees a smaller reduction in the ex-showroom price, but offers different warranty terms.
Who should buy one?
Conservative Buyers: Maruti’s stellar reputation for reliability makes its cars a popular choice with first-time buyers, and the e Vitara is no exception. For buyers looking for a reliable city car, the e Vitara is a great value proposition, with a significant reduction in ex-showroom price thanks to the BaaS scheme.
5. Citroen & Mahindra: The Niche Players
While much smaller than the aforementioned manufacturers, Citroen and Mahindra offer BaaS scheme on certain models, mostly their entry-level cars. Mahindra’s new Born Electric line (BE.05, BE.07) also makes use of a BaaS scheme, though specifics are scarce.
Model Battery Size Standard Price BaaS Price Battery Fee (per km)
Citroen eC3 29.2 kWh ₹11,61,000 ₹8,50,000 (approx) ₹3.50
Mahindra BE.05 40 kWh ₹16,00,000 ₹11,45,000 ₹4.20
The Cost Math: Is It Worth It?
Now, let’s get to the most important question of them all: is a BaaS plan worth it for you? The biggest advantage of a BaaS plan is the reduced ex-showroom price, but does that outweigh the additional cost of the battery fee?
Scenario A: The Low-Mileage User (10,000 km/year)
Car: Tata Nexon EV
Upfront Saving: ₹5,35,000
Annual Battery Cost: 10,000 km × ₹4.40 = ₹44,000
Break-even: Over 12 years of driving, the battery fees will have offset the ex-showroom savings.
Conclusion: Highly Beneficial
Scenario B: The High-Mileage User (30,000 km/year)
Car: Tata Nexon EV
Upfront Saving: ₹5,35,000
Annual Battery Cost: 30,000 km × ₹4.40 = ₹1,32,000
Break-even: 4-5 years of driving after buying the car will see the battery fees offset the ex-showroom savings.
The Battery Warranty: Your Friend
The biggest advantage of a BaaS plan might not be immediately apparent: you don’t have to worry about battery degradation. If the battery’s capacity is reduced by more than a certain percentage (usually 70-80%), the manufacturer will replace or repair it free of cost. This can save you a significant amount of money in the long run, as batteries tend to degrade with age and use.
The Sale: A Conundrum
Selling a car with a BaaS plan is slightly more complicated than selling a standard EV. Most manufacturers will allow the BaaS subscription to be transferred to the new owner, which can be an advantage if you’re selling the car quickly. However, the ex-showroom value of the car will be lower, as the battery fee isn’t included. This also means the new owner gets a significant discount on the car, which could be an advantage if you’re selling the car to someone who needs a discount.
You also have the option to buy the battery outright before selling the car, which turns it into a standard EV. This will increase the resale value, but it’s important to consider whether this is a worthwhile investment.
Who should choose BaaS?
If you:
Are looking to reduce your down payment and EMI.
Plan on keeping the car for 3-5 years (the typical ownership cycle).
Are concerned about battery degradation and warranty.
Want to try an EV but can’t afford the upfront cost.
Who shouldn’t choose BaaS?
If you:
Are a very high-mileage driver (e.g., commercial operators, driving >40,000 km/year)
Plan on keeping the car for 10+ years.
Prefer the simplicity of owning an EV outright.
In 2026, BaaS has gone from a gimmick to a mainstream financial tool. It has significantly democratised the EV market, and allowed a middle-class family to buy a Harrier EV for the price of a Kia Seltos. As the market matures, we can expect to see more manufacturers adopt this scheme, and make EVs a viable option for the average Indian buyer.
