Keeping up with the Tata Harrier’s robust appeal, the release of the Harrier.ev with dual motor Quad Wheel Drive (QWD) marks a significant plot twist in the Indian EV landscape. We all know that the OMEGA architecture borrowed from Land Rover is very capable indeed, and will be a significant edge for its electric variation.
We had a conversation with Anand Kulkarni, Product Line Head for EV Passenger Vehicles at Tata Motors, to further understand the complex thought behind this new SUV.
Quad Motor Drive Smartly Delivers All-Wheel Capability
One of the most significant additions to the recipe is its dual motor all-wheel drive configuration, which Tata refers to as Quad Wheel Drive. This setup isn't merely about brute force. As Kulkarni explains, the system is rear-biased by design but can redistribute torque based on traction conditions in real time. Unlike ICE-based AWD setups that depend on a central transfer case and mechanical differentials, the Harrier.ev's dual motors operate independently, safely modulated by software that constantly assesses wheel speed and grip.
There has been extreme attention to the dynamic biasing algorithm engineered by Tata. The car intelligently limits torque to a slipping wheel and diverts it to the one with better traction, eliminating the need for physical locking differentials. This approach not only improves off-road ability but significantly enhances the efficiency of the motors. According to Tata’s internal testing, this software-driven AWD setup contributes a 7%–8% improvement in range through intelligent torque management.
From ICE To Pure-EV Layout
Underpinned by the OMEGA ARC platform, it is originally based on Land Rover’s D8 architecture. Kulkarni clarified that the Gen 2 Active EV+ platform used here is far from a retrofit. The floor has been entirely reworked to accommodate the battery pack within the chassis, allowing a flat floor and optimised weight distribution. Though the body shell might resemble the ICE Harrier, the underpinnings have been thoroughly re-engineered.
This approach is able to offer structural advantages without compromising on packaging. More importantly, it positions Tata's Active EV+ platform as one that is pure electric in architecture, though not marketed as a “born EV” in the marketing sense. It is also designed to support future consolidation technologies, including the integration of the motor, inverter, gearbox, DC-DC converter, and on-board charger into a single power electronics unit. As he notes, the possibilities are virtually limitless.
Battery Chemistry Is Based On Stability Over Speculation
Tata Motors has opted to continue with LFP (Lithium Iron Phosphate) battery chemistry for the Harrier.ev. The decision is grounded in the reason that LFP offers a balanced mix of safety, longevity and cost-efficiency, particularly suited to Indian operating conditions. Kulkarni pointed out that current energy density figures for LFP batteries are already nearing 210 Wh per kilogramme, up from around 170 just a few years ago, with a 2–2.5% annual increase in density expected.
This chemistry, while not the highest in outright energy density, enables Tata to offer a longer battery warranty, including the option of a lifetime warranty for first owners. Although contingent on usage conditions, it reflects the brand’s confidence in the chemistry’s reliability over time.
Smart Electronics Suite
Apart from platform and batteries, Harrier.ev is also Tata’s most software-defined vehicle to date. From over-the-air updates to terrain-specific torque mapping, the Harrier.ev incorporates the early layers of what the industry specifies as Software Defined Vehicles (SDVs). Tata’s approach includes domain controllers, telematics, adaptive drive modes and predictive energy use, all pointing towards Level 2 autonomy and beyond.
An important distinction made by Kulkarni was that the Harrier.ev is not trying to impress with superficial screens or gimmicks. Instead, it integrates electronic architecture where it matters: in traction control, ride quality, predictive efficiency, and digital driver support. In a shift away from previous EV launches that chased flashy interiors, the Harrier.ev’s electronic package feels functional, grounded, and well-judged.
With a real-world range of around 500 kilometres and AWD capability, the Harrier.ev appeals to the evolving customer profile that values both versatility and sustainable choices. This is also a buyer who demands refinement without flamboyance, exactly what the Harrier.ev’s engineering philosophy reflects.
Rare Earths & The China Question
Inevitably, the question of rare-earth dependency and battery material sourcing surfaced. Tata appears to be preparing across timelines, protected for the short term, diversifying supply chains in the medium term, and exploring magnet-free drive technologies in the long run. Kulkarni believes technology will adapt, even if it means sacrificing compactness or efficiency for supply chain flexibility. The strategy is clear: build for today, prepare for tomorrow.
