If you specifically need a **7-seater electric car**, options remain limited in India in 2026, though models such as the Mahindra XUV.e8 are expected to expand that segment. If you have a budget (for example **under ₹20 lakh**, **₹30 lakh**, or **₹50 lakh**), I can narrow it down to the most spacious EVs within that range.

When it comes to sheer cabin space, legroom, and overall comfort, the defining factor is usually whether the car is built on a **born-EV (dedicated electric) platform**, which eliminates the engine bay and transmission tunnel to maximize cabin room. The most spacious electric cars available in India across different price segments feature these standout choices: --- ## 1. Budget to Mid-Range (₹15 Lakh – ₹30 Lakh) ### Tata Sierra EV * **Why it wins on space:** Revived as a premium born-EV SUV, the Sierra EV features a long 2730mm wheelbase. It is specifically designed to offer an ultra-spacious, lounge-like rear cabin experience with a massive panoramic view, making it the roomiest in its price class. * **Key Specs:** 63–75 kWh battery | ~500–665 km claimed range | Dedicated EV platform. ### Mahindra XEV 9e / XEV 9S * **Why it wins on space:** Built on Mahindra’s brand-new INGLO dedicated electric platform, these SUVs push the wheels to the absolute corners of the car. The completely flat floor translates to incredible legroom and shoulder room for three adults in the back. * **Key Specs:** 79 kWh battery | ~656–679 km claimed range. --- ## 2. Premium & Luxury Segment (₹40 Lakh – ₹1.5 Crore) If budget isn't a constraint, these models are essentially rolling lounges: ### Kia EV9 * **Why it wins on space:** If you need a **3-row electric SUV**, this is the undisputed space king. It has a massive wheelbase of over 3100mm. The second-row captain seats can even swivel 180 degrees, creating a literal conference-room or living-room setup inside the car. * **Key Specs:** 99.8 kWh battery | 7-seater / 6-seater luxury layouts. ### BYD Denza D9 / BYD e6 (MPV Segment) * **Why it wins on space:** Purpose-built electric MPVs like the BYD e6 (and the premium Denza line) completely deprioritize sporty looks in favor of ultimate passenger volume. The sliding rear doors open up to a cavernous cabin with massive headroom and legroom. ### BMW i7 & Mercedes-Benz EQS * **Why they win on space:** In the ultra-luxury sedan segment, these cars offer unmatched rear-seat luxury. The long-wheelbase platforms allow passengers to completely recline, accompanied by theater screens and massage functions. --- ### Summary Table | Car Model | Segment / Body Style | Key Space Highlight | Price Range (Approx.) | |:--- |:--- |:--- |:--- | | **Tata Sierra EV** | Mid-size SUV | Lounge-like rear seat, 2730mm wheelbase | ₹18.79 – ₹26.48 Lakh | | **Mahindra XEV 9e** | Premium Coupe-SUV | Flat floor, maximum shoulder room | ₹21.90 – ₹31.25 Lakh | | **Kia EV9** | Luxury Full-size SUV | 3 Rows, Swiveling captain chairs | ₹1 Crore+ | | **BYD e6 / MPVs** | Multi-Purpose Vehicle | Cavernous legroom, huge boot capacity | ₹30 Lakh+ | Are you looking for a spacious 5-seater family SUV, or do you specifically need a 3-row 6/7-seater vehicle?
