Diwali falls on Sunday 8 November 2026, which leaves eight weeks between now and the year’s biggest car-buying window. In that time at least six electric cars are due to launch or open bookings in India, from the Porsche Cayenne Electric on 30 September to the Tata Safari EV before the festival, and at least two more, the Hyundai HE1i and the Tata Avinya, are pencilled in for December. At the same time Tata, Mahindra, Hyundai, Kia and BYD are running some of the deepest EV discounts of the year. This guide lays out every confirmed and credibly reported EV launch between now and Diwali, what each one means for the cars already on sale, and a straightforward rule for deciding whether to buy this month or hold out.

The launch calendar, September to December 2026

Model Segment Expected timing Expected price Status
Porsche Cayenne Electric Luxury SUV 30 September From about Rs 1.77 crore Date confirmed by Porsche
MG IM6 Premium SUV, MG Select October About Rs 60 lakh Full import, bookings under way
Volvo EX90 and ES90 Luxury SUV and sedan 12 October Rs 1 to 1.5 crore Date confirmed by Volvo
Tata Safari EV Three-row SUV Before Diwali Rs 22.5 to 32 lakh estimates Confirmed by Tata for the festive season
JSW Chery iCar V23 Boxy compact SUV October to November Rs 20 to 25 lakh Spied testing; timing reports vary
Tata Sierra EV special editions Mid-size SUV Festive season Above the Rs 18.79 to 26.48 lakh range Reported, not dated
Hyundai HE1i Compact SUV By December Rs 9.79 to 12.99 lakh expected Confirmed for 2026; details in our report
Tata Avinya Premium sub-brand End of 2026 Not announced Confirmed by Tata, first model later

Three of these are hard dates from the manufacturer: the Cayenne Electric on 30 September, which we previewed in our Porsche Cayenne Electric India debut report, and the two Volvos on 12 October, covered in our piece on the Volvo EX90 and ES90 launch. The Safari EV is confirmed for the festive window but not dated. The rest are reported with varying confidence.

What each launch does to the cars already on sale

Under Rs 15 lakh: wait for the Hyundai HE1i only if you can wait until December

The HE1i is the launch that matters most to mass-market buyers, because Hyundai is targeting Rs 9.79 to 12.99 lakh, straight at the Punch EV, Nexon EV, XUV 3XO EV and Syros EV. But it is a December car, not a Diwali car, and Hyundai’s own timeline for its Exide cells has slipped, as we set out in our HE1i launch report. If your current car is dying and you need wheels before the festival, the Punch EV at Rs 9.79 lakh with September’s discounts, the Nexon EV 45 kWh at Rs 12.49 lakh and the Syros EV from Rs 13.49 lakh are the safe choices. Nothing launching before Diwali undercuts them.

Rs 15 to 30 lakh: the Safari EV reshapes the three-row market

Buyers looking at the Mahindra XEV 9S six-seater, the Kia Carens Clavis EV or the BYD eMax 7 should wait for the Safari EV if they can, because Tata has confirmed it for the festive season and it is expected to share the Harrier EV’s 65 and 75 kWh packs with rear- and all-wheel-drive options. Even if you end up buying the XEV 9S, whose captain-seat pricing we broke down in our XEV 9S six-seater explainer, Mahindra is likely to sweeten its offer the week Tata announces prices. The Sierra EV special editions are cosmetic; they do not change the underlying Rs 18.79 to 26.48 lakh car.

Rs 50 lakh and above: everything changes in October

The MG IM6 at about Rs 60 lakh with a 100 kWh pack and up to 625 km claimed, the Volvo EX90 and ES90 at Rs 1 to 1.5 crore, the Cayenne Electric at about Rs 1.77 crore and the freshly launched BMW i5 LWB at Rs 79.6 lakh and i7 facelift mean that the premium EV buyer has more genuinely new choice between now and Diwali than in any previous quarter. Nobody in this bracket should sign for a BMW iX, Mercedes EQE or Kia EV9 without first seeing October’s prices.

The discounts on the table right now

September’s offers are substantial: Tata is discounting the Harrier EV by up to Rs 2.75 lakh and the Curvv EV by up to Rs 3.35 lakh, Mahindra has up to Rs 2.5 lakh on the XUV400, and Hyundai, Kia and BYD are all running festive schemes, as we listed in our round-up of EV discounts in September 2026. The question is whether they get better in October and November. History says they usually do not on volume models; manufacturers front-load festive offers in September to build the Navratri delivery pipeline, and Diwali-week deals tend to be on slow-moving variants and colours rather than across the range. Where offers do deepen is on outgoing cars: expect the Nexon EV’s older 30 kWh variants, the XUV400, the ZS EV and any stock of pre-facelift models to get another Rs 50,000 to 1 lakh in the last fortnight before Diwali.

If you are considering Buy now or wait? Why
Punch EV, Nexon EV, XUV 3XO EV, Syros EV Buy now Nothing launches in the segment before Diwali; HE1i is December; September discounts are strong
Curvv EV, Creta Electric, Windsor EV, BE 6 Buy now, unless the iCar V23’s boxy design appeals Discounts are at their peak; the iCar V23 is unpriced and undated
XEV 9S, Carens Clavis EV, eMax 7, Harrier EV Wait for the Safari EV price Tata has confirmed a festive launch; rivals will respond
Kia EV9, BMW iX, Mercedes EQE, Hyundai Ioniq 5 Wait until mid-October IM6, EX90, ES90 and i5 LWB all land in the window
Any luxury EV above Rs 1.5 crore Wait for 30 September and 12 October Cayenne Electric and EX90 set new benchmarks

The maths of waiting

Waiting has a cost that is easy to ignore. If you are currently running a petrol car 1,500 km a month, every month you delay costs about Rs 10,000 more in fuel than the EV would, using the per-km figures from our electric versus petrol five-year cost comparison. Two months of waiting for a launch that then has a three-month waiting list can cost Rs 50,000 in fuel alone, which is more than the extra discount you are likely to extract. On the other hand, buying a car that is superseded within weeks hurts resale, which we quantified in our guide to used EV resale values, and it hurts most in the Rs 20 to 35 lakh band where the Safari EV lands.

Registration timing matters too. A car registered in September or October 2026 carries a 2026 registration for its resale life just as a November one does, so there is no calendar-year advantage to waiting for Diwali itself. And in states such as Delhi, Maharashtra and Telangana where road tax on EVs is waived, the on-road saving does not change with the date; our state-by-state on-road price guide has the current figures.

A four-question rule

  1. Is there a confirmed launch in your exact segment and budget before 8 November? For most buyers under Rs 20 lakh the answer is no, so buy now.
  2. Is the launch a genuinely new model or a special edition? Special editions and facelifts rarely change prices of the base car; new models do.
  3. Can you live without the car for the launch date plus a realistic three-month delivery wait? New Tata and Mahindra EVs have run waiting lists of two to four months at launch.
  4. Does the current discount exceed 5 per cent of the car’s price? If yes, it is unlikely to get materially better, and the offer may be withdrawn once festive demand picks up.

Apply those four questions and most buyers land in the same place: mass-market EVs are a buy in September, three-row and premium EVs are a wait until Tata and the luxury brands have shown their hands in October.

FAQ

Which electric cars are launching in India before Diwali 2026?

The Porsche Cayenne Electric on 30 September, the Volvo EX90 and ES90 on 12 October, the MG IM6 in October, and the Tata Safari EV before Diwali on 8 November. The JSW Chery iCar V23 is reported for October or November but not confirmed.

Should I wait for the Hyundai HE1i?

Only if you can wait until December. Hyundai has confirmed the compact electric SUV for the end of 2026 at an expected Rs 9.79 to 12.99 lakh, but it will not be on sale before Diwali.

Will EV discounts get bigger closer to Diwali?

Usually not on popular models; manufacturers front-load festive offers in September. Deeper cuts closer to Diwali tend to appear on outgoing variants and slow-moving stock.

Is it better to register a car in October or after Diwali?

There is no difference for resale within the same calendar year, and EV road-tax waivers in states such as Delhi and Maharashtra do not depend on the date. Buy when the car and price are right.
