In February 2021, Tata Nexon EV buyers in Delhi began publicly complaining that the car never delivered its headline range. The brochure and all of Tata's marketing quoted 312 km on a full charge — a figure certified by ARAI, India's official vehicle-testing agency. A Delhi buyer told the transport department his car had never returned more than 200 km despite following the dealer's advice on how to drive it.

In March 2021 the Delhi Transport Commission suspended the Nexon EV from the city's EV subsidy list, with transport minister Kailash Gahlot saying Delhi would back EVs 'but not at the cost of trust and confidence of citizens in claims by manufacturers.' Tata's defence was procedural: the 312 km figure was ARAI-certified, and certification is the legal standard. It argued real-world range varies with driving style and AC use, and that owners see ~10% improvement as they get familiar with the car. The Delhi High Court stayed the suspension on 11 March 2021 while the case proceeded.

The deeper problem was the test itself. As Autocar India explained, ARAI lets M1-category EVs certify range on the urban Part One cycle only — an average of 19 km/h with air-conditioning and lights switched off. Every EV then on sale in India (Hyundai Kona, MG ZS EV included) showed the same gap between certified and real range in independent road tests. Tata was technically compliant on a claim that no owner could reproduce.

The exposure didn't fade. In October 2025 the District Consumer Commission in Jhansi ordered Tata Motors' EV arm and its dealer JMK Motors to refund a Nexon EV Max buyer his full ₹17.49 lakh, plus 7% annual interest and a ₹15,000 penalty, after the car — sold in 2023 on a claimed 453 km charge — managed only 280 km.

Delhi suspended the Nexon EV's purchase subsidy in March 2021; in October 2025 a consumer court ordered a ₹17.49 lakh full refund plus 7% interest and a ₹15,000 penalty.

The 312 km claim came from a test that runs a 19 km/h urban cycle with the AC off — certified, but unreachable in the traffic and heat the car was sold into.

Owners were reporting 150–200 km against 312 km advertised: a gap large enough to read as a broken promise, not a fine-print variance.

Tata's response defended the certificate rather than the customer, conceding the emotional framing — an early adopter who felt cheated — to the complainants and the city's transport department.

Delhi tied its EV subsidy money to the advertised range, which gave the city both the standing and the incentive to act when the claim collapsed.

The labelling loophole was industry-wide, but the biggest seller wore it: the market leader is where the gap gets named, sampled and litigated.

A lab-certified number can be literally true and commercially misleading anyway. If you advertise a test-cycle figure, assume buyers will hold you to it — or the gap becomes a lawsuit.

The Delhi High Court stayed the suspension in March 2021 and Tata kept selling, but the episode pushed real-world EV range into India's mainstream auto coverage. Tata launched the bigger-battery Nexon EV Max in 2022 with an even larger certified figure — 453 km — and in October 2025 the Jhansi District Consumer Commission found the same pattern: 280 km actual against 453 km claimed. It ordered Tata Motors Electric and dealer JMK Motors to refund ₹17.49 lakh with 7% interest and pay ₹15,000 as penalty. Launch questions in India now lead with real-world range, not certified range.
