Tata Harrier EV QWD Range Test From 100% to 0% || Full Battery Drain Test || Can This Give 500km?
We were trying to charge the Tata Har EV to almost 100% to extract the maximum possible range. Extraction means eco mode region in level number three. AC will be running with approximately 26°. How much can I extract from the QWD? Well, it’s going to be a surprise package. Stay with us for the entire video. [Music] Now as we set out, let me just reset the driver info display for the distance done and the efficiency. Trip A goes reset and likewise for trip B. It goes reset. We will be in the eco mode. Current battery is 99% and the region level is two and this is three. Let’s see if we can come back to Delhi without any charging on the way. [Music] All right. So, we left at 99% and had reset the trip meter. Although early in the morning, we still had a fair bit of local traffic coming in. Uh nevertheless, soon we joined the loot that goes towards the Delhi Mumbai Expressway and that is where we are right now. Uh I’ll try to show you the distance we have covered and the efficiency every uh 10%. So at 89% we had used 10% of the charge uh for a very healthy 49 km. Uh again my AC is running uh eco mode and a bit of traffic coming into the picture. Uh on the expressway now holding around 85 on the speedometer and at 79% or when we use 20% of battery we’ve done 91 km. I do understand in the last 10% it has been only 42 km but then again at highway speeds you don’t have regen helping you. uh it’s just a cruise on you are cruising at a specific speed and there is no help or push from region that is why sometimes at highway speeds the range drops nevertheless uh fingers are crossed this is the QWD both the motors are working in tandem to get us going let’s see what happens as we go forward uh good views around Ara and yeah less traffic enjoy the Hey. [Music] [Applause] [Music] All right, updates from the drive. Uh, at 69%age or using 30% of the battery, we were at 138 km. And after using 40% battery, we are at 181 km. Efficiency as per display is 166 which basically means on paper 450 km is possible. AC is running two of us and it’s QWD. Both the motors are working. In case you go for the 4×2 version, you can expect a higher range by around 5 to 10%. So that’s a healthy figure, right? Uh the Harrier EV itself is available in three main versions of adventure, fearless plus and empowered. Uh QWD or the allwheel drive is only for the empowered. Likewise, stealth is also only for the empowered. Talking of QWD, we have experienced the car off the road. A detailed video is live on YouTube. It’s running over there. And we did have our share of fun. We also have done um flatout exploration runs in the boost mode 0 to 150 for example. We also have had the track experience. So all that was done. It was time now for the extraction of the maximum possible range. So yeah, let’s see what it can do. We will try to get the battery down to under 5%. Fingers crossed. [Music] Now on the move you can see the consumption pattern in the Harrier EV from the screen itself. Uh it shows you the consumption for the traction uh the cooling that is the AC or the seat ventilation. Uh other parameters regen and the instantaneous efficiency as well. Uh the average of course is on the speedometer console but uh this is uh pretty uh helpful and keeps you busy as well on what is happening in terms of a straight road or going up or coming down a fly over. [Music] Now, practically speaking, when I left the hotel in the morning, my aim was to get anything between 450 and 470 km max because this is QWD. But, uh, in the last 10%, we have gone 54 km. Great stuff. It could be gravity, it could be the Harit Eevee, it could be God helping us out. But, uh, this means that we can reach the hotel at 500 km. Uh, I’ve taken a U-turn here just to get some more kilometers on the expressway. And the aim now is to reach the hotel at 500 kilometers with still some battery left in the AR EV. I think we can do that. [Music] Now gravity is a great thing and this is interesting. Uh just after the cut of Japur city, we carried on for a few kilometers. We took a U-turn back towards our destination and the area around Jaipur is slightly higher up as compared to Delhi. So we are now losing elevation. The efficiency is improving. Uh having used 60% of the battery, we have done 281 km. In the last 10% itself, we’ve done 52 km. This is so so encouraging. Uh we still have 39% of battery left and um 450 plus is a given. But how much can we extract? Extract is the important word. Fingers crossed. [Music] We are down to the last 20% of the battery and uh done 385 kilometers in what is basically 79%. Uh the issue is I sort of miscalculated. Our hotel is 120 from here. So we need to get 6 km for every 1% and no region it’s a highway. So I think it’s time to go into hyperiling mode to ensure we don’t get standard. 120 km 20% left. [Music] Crazy weather here. Super cloudy on the right side, drizzling as well slightly. And um not complaining because I’ve gone into the hyper mileing mode. Speeds are down to around 60 65. My AC is off, so I do need good good weather. 15% battery, 85 km to go. Currently on the highway, but we will be having a fair bit of urban traffic as well. Sort of a miscalculation, sort of an adventure, but why not? Let’s see. [Music] Now, this is fun. It’s pouring now. It’s raining right now. That’s getting down the so that’s going to help us slightly. Also on the last 10% of the battery I’m still over 623 kmp in terms of speed. So the turtle mode is on but that doesn’t mean you are limited to 40 50 kmp. You can still be at 60 plus to be with the traffic or ahead of traffic. Uh distance to the hotel is 60 km. Adventure is on and it’s raining. Great experience. All right, down to the last 5%. Uh, now it’s really gone into the power saving mode. You can also hear the chime non-stop. Uh, some uh features of uh Adas is also not available. For example, adaptive tools control is off, but I can still hold 60. That’s so good. Uh 5% sometimes if you think that that will mean crawling at 3040, that’s not the case. we can still be at a decent pace of 60. Uh the hotel is very far off. Let’s see till what point we can reach and once it’s dead at zero I’ll show you the final figure. So basically a battery drain test or drive to death test 99% final figure in the QWD should be nice. [Music] [Music] Heat. Heat. [Music] So finally down to zero. This is an exact 500 km. In fact, if you remember, we started at 99% and we’ve ended at 0%. So, not even 100% charge, 500 in the QWD. There you go. Finally, the end of our hyper mileing run with the QWD Harrier EV. It’s got the performance, it’s got the off-road ability, and if driven with a light right foot, it can give you 500 km on a full charge. Mind you, right now the car is not moving torque because of the safety reasons and for the battery health. But the features, electronics are still working. For example, I did use the power tailgate, the central locking, the indicators, they are all all working. Guys, similar to this kind of run, we also did something from Delhi to the first village of India, Cahoo Arunachal to the China border in the younger sibling of the Harrier, the curved EV. That was a India book of record. After this video, don’t forget to check that video out as well. The link to that video is currently in the description section below. Also, before I end, if you do invest into the non QWD or the 4×2 version, you can definitely get 8 to 10% more. Two motors versus one motor can make a lot of difference.
The most extensive 100% to 0% (with drain) range test of the Tata Harrier EV is here. For the video, we had the top spec QWD with us – two motors powering the four wheels. This range test was done on the Delhi – Mumbai expressway and our aim was to extract the best. Would this mean hypermiling as well? Watch the video for all details
