The Tata Harrier EV, launched a couple of months ago, is offered in two battery pack options — 65kWh and a larger 75kWh unit. Recently, we got our hands on the Harrier EV QWD with the 75kWh battery pack, and decided to put it through our comprehensive real-world range test from 100 per cent charge, all the way down to zero.The Harrier EV QWD uses the larger 75kWh battery pack paired with dual motors—one on each axle—delivering a combined output of 313bhp and 504Nm of torque. Tata claims an impressive 622km range (MIDC) on a full charge. Additionally, the brand also mentions an expected ‘real-world’ C75 range band of 460-490km, which is what most customers can expect, depending on their driving conditions and style.For our test, we began with the battery charged to 100 per cent and maintained the car in its default City drive mode, the mode in which the Harrier EV starts up every time. Regen was kept at Level 1, which allows a more natural coasting feel, and closely replicates how most owners would drive daily. The air-conditioning was kept between 23-24 degrees, with fan speeds set between one and two.
Our range test was roughly divided 50:50 between city and highway driving, representing a realistic usage pattern for most EV buyers. The city portion involved navigating through moderate urban traffic—think stop-start congestion on arterial roads with average speeds hovering around 25-35kmph. Highways, on the other hand, were steady cruises at 80-100kmph, with occasional overtakes to mimic real-life highway jaunts. No aggressive acceleration or high-speed runs were factored in; this was about everyday usability, not track-day heroics.
The Drive: From Full Charge to Empty
Kicking off in the bustling streets of Mumbai, the Harrier EV felt composed and effortless. The City mode tuned the throttle response for smoother urban maneuvers, and the Level 1 regen provided just enough deceleration on lifts without feeling jerky—perfect for foot-on-pedal consistency. The dual-motor AWD setup added a layer of confidence, especially when darting through gaps in traffic, though we stuck to eco-conscious driving to maximize range.
As we transitioned to the highway stretch toward Pune, the SUV settled into a rhythmic cruise. The cabin remained whisper-quiet, with the AC holding steady without guzzling extra juice. Energy consumption averaged around 15.2kWh/100km in the city (thanks to frequent idling and short bursts) and dipped to 13.8kWh/100km on the open road. The trip computer was optimistic at first, projecting over 500km, but it gradually adjusted downward as real-world variables like wind resistance and slight inclines kicked in.
We pushed on relentlessly, monitoring the battery state-of-charge (SoC) every 10 per cent drop. By the 50 per cent mark, we’d covered about 220km—a solid efficiency readout. The 25 per cent threshold brought us to roughly 330km, where the projected range started dipping below Tata’s C75 estimate. No major hiccups here; the infotainment stayed responsive, and the ADAS features (like adaptive cruise) were lightly used to conserve power.
Hitting the Wall: Low Battery Behaviors
Things got interesting below 10 per cent SoC. The Harrier EV imposed a speed cap at 78kmph, forcing a more sedate pace that felt restrictive but sensible for preserving the dregs. At 5 per cent, it tightened further to 60kmph, and the AC auto-shut off to redirect power to propulsion—leaving us in a warm-ish cabin but with a few more kilometers banked. Finally, entering limp mode, the SUV crawled forward, prioritizing essentials like steering and brakes.
After a grueling 10+ hours of mixed driving, the Harrier EV sputtered to a halt at exactly 438.2km from full charge. This clocks in at about 70 per cent of the MIDC claim but falls just shy of Tata’s 460-490km real-world band. Considering the 50:50 split, city efficiency dragged the overall figure down slightly compared to pure highway runs, where we’ve seen peers nudge closer to 470km in similar tests.
| Aspect | City (50%) | Highway (50%) | Combined |
|---|---|---|---|
| Distance Covered | 219.1km | 219.1km | 438.2km |
| Avg. Speed | 28kmph | 85kmph | 56.5kmph |
| Energy Consumption | 15.2kWh/100km | 13.8kWh/100km | 14.5kWh/100km |
| Efficiency Rating | Moderate | Excellent | Good |
Key Takeaways and Minor Gripes
This test underscores the Harrier EV’s prowess as a long-haul EV SUV. At 438km, it’s more than enough for inter-city hops or daily commutes without range anxiety gnawing at you. The 75kWh pack shines in balanced usage, outpacing smaller-battery rivals like the 65kWh Harrier EV (which we’ve clocked at ~380km in similar conditions). Load factors—solo driver, no cargo—helped here; add passengers or luggage, and expect a 10-15 per cent dip.
That said, a few quirks surfaced: The powered driver seat emitted a faint creak under adjustment, and the blind-spot monitor feed occasionally froze on the cluster, even post-deactivation—likely a software gremlin Tata can patch via OTA. Regen could use a tad more progression for highway coasting, but Level 1’s natural feel won us over for mixed drives.In the grand scheme, the Tata Harrier EV 75kWh QWD delivers where it counts: reliable, real-world range in an AWD package that’s fun and feature-packed. If you’re eyeing an electric family hauler with go-anywhere vibes, this one’s a strong contender—just temper those MIDC dreams with a healthy dose of highway reality.
For those chasing every kilometer, bump up regen to Level 3 and skip the AC on milder days; we’ve squeezed an extra 30-40km in follow-ups.Priced from ₹28.5 lakh (ex-showroom), the Harrier EV QWD isn’t the cheapest in its class, but its blend of range, power, and Tata’s seven-year battery warranty makes a compelling case.
