Tata Harrier EV at Quad Day: Capability without drama and technology with real purpose
As SUVs across the board turn to flash and flare, Tata Motors has taken a different route with the Harrier EV: one of restraint, refinement, and relevance. From my hands-on time with the vehicle—particularly the off-road section—to the deep dive conversations with Anand Kulkarni, Chief Product Officer at Tata Passenger Electric Mobility, it became evident that this isn't just a step forward for Tata Motors. It's a quiet leap.

Of all the four thematic zones at the Quad day—Performance, Precision, Tech, and Off-Road—it was the last one that offered the rarest commodity at events like this: an actual chance to drive. Not as a co-passenger, not in a closed loop—but a real, hands-on crawl through chaos.
And chaos it was. The off-road course was no casual slush track—it was a tightly packed sequence of punishing terrain features that would challenge even seasoned ICE SUVs. It began with a rock bed crawl that tested low-speed control and wheel articulation, followed by an axle twister engineered to lift at least one tyre off the ground. From there, the trail threw up sharp 35-degree inclines and declines, pushing the vehicle's traction management and braking systems to the limit.
The course continued with side slopes, camel humps, deep sand traps, water wading sections, and even a staircase climb to cap it all off—each obstacle demanding precision, poise, and a drivetrain capable of thinking on its feet. But what stood out wasn't just that the Harrier EV did all of it. It was how little it fussed while doing so.
There was no jerky throttle response, no electronic overcorrection, no wheelspin theatre. It felt as if the SUV had pre-read the course. Every mode—Rock Crawl, Sand, Mud & Ruts—was calibrated to deliver just enough intervention. Not more.
This composure stems from a very specific drivetrain setup: a rear-biased Quad Wheel Drive (QWD) system powered by two independent motors. The rear motor, a PMSM (Permanent Magnet Synchronous Motor), does most of the work. The front, an induction motor, wakes up only when needed.
As Kulkarni, the chief architect behind Tata's EVs, explained, this decision wasn't just about traction—it was about efficiency. 'PMSM motors are great, but they consume power even when not in use. Induction motors don't. So for a setup where the front axle is often disengaged, it made perfect sense."
What this means practically is that during a slow rock crawl or a sudden steep climb, the rear motor delivers high torque, while the system dynamically checks whether the front needs to assist. And when it does, the transition is imperceptible.
Even during the axle twister, where one wheel was in the air, the software sensed the slip and reallocated torque within milliseconds. Kulkarni emphasized, 'We didn't use mechanical aids like diff locks. It's all software. Torque vectoring, traction prediction, terrain mapping—all of it is done by the brain of the car."
And it works. No drama. No mechanical clunks. Just progress.

If the Off-Road Zone was about physical proof, the Tech Zone was about technological vision—only this time, grounded in day-to-day Indian reality rather than Silicon Valley showmanship.
Here, the Harrier EV presented itself not just as an electric SUV, but as a Software-Defined Vehicle (SDV)—built on Tata's new 'T.idal' (Tata Intelligent Digital Architecture Layer) platform. Running 500 million lines of code, it connects everything from motor control to ADAS, infotainment, telematics, and payment systems.
But what makes 'T.idal' stand out is not just what it does, but what it consciously chooses not to overdo. It focuses on real-world utility rather than ticking boxes. Take the Low-Speed Autonomous Emergency Braking (AEB), for instance—it's not just another radar-based system thrown in for formality. It's carefully calibrated for India's dense, erratic traffic, where most Western ADAS setups either overreact with sudden braking or disengage altogether. The Tata Harrier EV gets several convinience features such as the Summon Mode which allows the car to park in a pararell parking without driver inputs
Then there's Dead-End Assist, a segment-first feature that allows the vehicle to automatically reverse along the last 50 meters of its path—a simple yet brilliant solution for tight lanes and tricky U-turn situations in crowded neighbourhoods. Summon Mode, activated via Tata's new circular key, lets the SUV inch in or out of tight parking spots autonomously, complete with full obstacle detection.
And the 540° transparent view camera system doesn't just offer a top-down perspective; it delivers real-time stitched visuals, including side and underbody views, enhanced with rim protection alerts—making it genuinely useful for negotiating potholes, high kerbs, or narrow parking bays.
What impressed me most wasn't that these features existed—but how calmly they worked. There was no jarring intervention. No frantic beeps. Just consistent, usable assistance. As Kulkarni put it: 'ADAS shouldn't be a backseat driver. It should feel like a co-driver—always watching, but never taking over unless it absolutely has to."
Even the AI-powered Park Assist, developed with Continental, was a lesson in subtlety. The system scanned irregular parking spaces (not laser-marked slots), identified viable options, and parked itself with steering, braking, and acceleration control. And if someone walked by? It stopped. Gently. Collaboration by design, not compromise
One of the more underrated aspects of the Harrier EV is how thoroughly it has been shaped through partnerships. Tata Motors has embraced a global collaboration model, but with Indian calibration and context firmly at its core. The result is a vehicle that reflects both international technological excellence and local relevance. Continental, for instance, provided the intelligence behind the ADAS suite and Auto Park Assist—custom-developed for India's unpredictable road realities.
As Prashanth Doraswamy, CEO of Continental India, described it, the system is 'a human-like AI that understands Indian parking challenges—unclear lines, sudden obstacles, narrow bays." Harman and Samsung delivered the world's first 14.5-inch Neo QLED display in a production car, paired with JBL Black's Dolby Atmos 5.1 audio system—not for flamboyance, but to create a 'third space" that seamlessly blends work, entertainment and travel.

On the drivetrain front, Tata AutoComp and Schaeffler engineered the front induction and rear PMSM motors, respectively, with TACO contributing India's first integrated induction EV drivetrain. The ADAS controller itself runs on Mobileye's globally benchmarked EyeQ chip, fine-tuned specifically for India's chaotic traffic environment. The acti.ev plus architecture, underpinning the Tata Harrier EV is a collaborative effort between Tata Motors and various other leading global suppliers
Qualcomm provides the SDV backbone, enabling over-the-air updates and modular software enhancements, while Bosch, ZF, LG Chem, and Magna form part of Tata's tier-one ecosystem, supporting everything from battery systems to structural components.
Yet, none of these partnerships were plug-and-play. Each supplier was asked to co-develop, co-calibrate, and rigorously test their systems with Indian use cases in mind. As Kulkarni succinctly put it, 'These aren't just tech tie-ups. They're part of a new Tata philosophy—collaboration by design." What the Tata Harrier EV really represents
The Tata Harrier EV doesn't overwhelm. It impresses with restraint, earns trust through refinement, and redefines what it means to be a true Indian electric SUV. It's capable where it matters, intelligent where it counts, and most importantly—it feels complete.
With a real-world C75 range of 480–505 km, support for 120 kW fast charging, V2L (Vehicle to Load) and V2V (Vehicle to Vehicle), the Harrier EV isn't a flash-in-the-pan launch. It's Tata's opening move in a much bigger EV play.
More importantly, it's a product that acknowledges its customer—a 30–40-year-old urban explorer who wants range, refinement, and ruggedness, without feeling like they're compromising on identity or practicality.
This is an SUV built for weekday office commutes and weekend adventures, for chauffeured comfort and hands-on control, for those who want freedom without friction. In a market where most EVs still struggle to find balance, the Harrier EV finds its footing not in gimmicks, but in grounded, honest capability. And perhaps that's the boldest move of all.

JLR to face $2.1bn tariff hit: Chandra
Tata Group chairman N Chandrasekaran Mumbai: Tata Motors-owned British luxury carmaker Jaguar Land Rover faces potential tariff impacts of 1.6 billion pounds (about $2.1 billion) from new US trade measures, Tata Group chairman N Chandrasekaran said. He noted that ongoing mitigation plans aim to reduce this impact to 600 million pounds. "Tariff is a major issue, primarily for JLR," said Chandrasekaran at Tata Motors ' 80th AGM on Friday. "Without intervention, JLR's tariff rate would have gone from 2.5% to 27.5%. With the US-UK trade deal, the 27.5% tariff will drop to 10%. The overall impact even of the 10% will be 1.6 billion pounds. But JLR has taken a lot of steps through which it will be able to reduce the impact to 600 million pounds." This AGM marked Chandrasekaran's first appearance at a shareholder meeting after the Air India flight 171 crash on June 12, having missed shareholder meetings at Tata Consumer Products and TCS. The meeting held additional significance as it was the final AGM for Tata Motors before its division into two listed companies by year-end, focusing on passenger vehicles and commercial vehicles, respectively. Chandrasekaran also assured shareholders that China's export restrictions on rare earth magnets pose no immediate supply concerns, while the company explores alternative sourcing options. Rare earth elements play a crucial role in the production of permanent magnets, which are essential components in electric motors.

No supply issues for EV magnets, monitoring geopolitical risks closely: N. Chandrasekaran
Tata Motors chairman N. Chandrasekaran on Friday told shareholders at the company's 80th annual general meeting that the company is accelerating its electric vehicle (EV) strategy, even as it closely monitors supply chain and geopolitical risks that could affect growth. EVs accounted for 15 per cent of the company's passenger vehicle sales in the last financial year. Tata Motors now aims to reach 30 per cent electric vehicle penetration well before 2030. 'We already have a portfolio—with Nexon EV , Punch EV, Tiago and Tigor—and we have several more models in the pipeline,' Chandrasekaran said. Tata Motors continues to lead the Indian EV market with over 50 per cent share, although this has declined from 79 per cent two years ago as Mahindra & Mahindra, Hyundai Motor India and MG Motor India expand their offerings. 'Yes, competition has increased, but we remain fully committed and have a runway,' he said. Supply chain, tariff impact under watch Chandrasekaran said the company is monitoring supply chain and geopolitical risks, including the sourcing of rare earth magnets used in EVs. 'We are not facing any issues. We are able to source the magnets we need and have the right level of inventory,' he said. 'We're also working with the government on alternative resources. This is something we are watching very carefully.' He addressed concerns around increased US tariffs on UK-made vehicles, which would affect Jaguar Land Rover . 'If the tariffs had gone to 27.5 per cent, the impact would have been £1.6 billion. With the UK-US trade deal , that's coming down to 10 per cent, and JLR's mitigation steps will reduce the impact to around £600 million,' he said. Tata Motors will participate in the government's EV bus programmes through its mobility business and is testing 12 hydrogen buses and trucks. 'The cost of production and operations for hydrogen is still high. This won't scale in the near term,' he said. The company's plan to demerge its passenger and commercial vehicle businesses remains on schedule. Both units are expected to list separately in the December quarter. 'All three businesses have balance sheets and cash flows. There is no need for large-scale debt unless a strategic opportunity arises,' Chandrasekaran added.

Tata Motors working with govt, looking alternate sources for magnets: Chairman N Chandrasekaran
Tata Motors is working with the government and is also taking steps to procure magnets from alternate sources in the wake of China restricting exports of rare earth elements , company Chairman N Chandrasekaran told its shareholders on Friday. Responding to queries from shareholders on the impact of China's move to restrict exports of rare earth elements and shortage of magnets, he said, "As of now, this is not a concern, but this is something that we are watching very carefully." "As of now, we are okay. We are not facing are able to source the magnets that we need, and also we have plans for having the right level of inventory. We are working with the government. Also, we are working on sourcing from alternate sources," Chandrasekaran noted. China's restrictions on the export of rare earth elements and related magnets are affecting the domestic auto and white goods sectors. The automobile industry had sought government support in expediting approvals from the Chinese government for importing rare earth magnets used in various applications, including passenger cars. To another query on the impact of the ongoing Iran-Israel war on the company's business, he said, "It is very difficult to answer what will be a war kind of situation look like." However, he said Tata Motors group's three firms - commercial vehicle, passenger vehicles and JLR - have a very strong platform. "They will be able to tide over any of these geopolitical issues in the short term but are completely ready and poised for excellent growth and leverage the opportunity that this industry has to offer," Chandrsekaran asserted. Earlier in opening address, he said that going forward, volatility will continue to mark economic cycles - from widespread geopolitical conflicts, military escalations, the redrawing of supply chains and tariff regimes, to AI and energy transition. Nowhere are all these disruptions visible more than in the automotive sector . "Given the enormous amount of work we have done over the past few years - from simplifying the businesses to making big strategic bets to strengthening our financial position - our businesses are structured to not just handle this environment, but to thrive," he asserted. Responding to a query on passenger vehicle business expansion in international markets, he said, "This is something that we are always in discussions but we are waiting for the right geopolitical environment to be able to launch but we are getting prepared." To another query on the completion of demerger of Tata Motors' commercial and passenger vehicle verticals into separate entities, Chandrasekaran said, "We think the demerger will happen in the last quarter of this year. "First, the PV company will list and then the CV company will list a couple of months later. It will happen, in our estimate, sometime around October-November-December quarter."
