Tata Nexon EV Max: Calculated real time range after a 300 km trip

The drive comprised of 30 kms inside city with moderate traffic, and 270 kms on a 4 lane expressway. Throughout the drive, the AC was on and audio was playing. Google navigation was also in use.

I did a 300 km trip, 30 kms inside city with moderate traffic, and 270 kms on a 4 lane expressway. I don’t know if my calculations are difficult to follow but I will try to explain.

More than Kwatt/hr I have worked out my calculations based on kms the car travels per percent of charge. I know it might not be strictly accurate because when the charge goes less than 10%, I heard AC and other systems cut off and the car can travel further.

All through the drive, the AC was on and audio was playing. Google navigation was also in use.

• For the first 107 kms it consumed 54% battery. This was in ECO mode and I did a steady 110-115 kmph. I drove like my Jeep trying to maintain a smooth driving style with regen at stage 1 and minimum braking. Turns out to be a mistake.
• 2nd 69 kms consumed 36%. Half of this distance was highway with same driving style as I had mentioned above and remaining in city.
• The 3rd 86 kms I reduced my speed to 90-100 kmph and regen was in stage 2. Consumed 36% charge.
• Last 41 kms I used Sport mode and had a blast though I did not cross 120 kmph. Regen was in stage 3. I was hardly touching the brake to slow down. It’s a learning curve but I slowly improved. The surprising part is this yielded the best figures.

As per my calculation from this drive, I could go for 241 kms on a full charge and averaging out the entire distance of 299kms with 143% battery consumed I could have gone 210kms.

Again, this is not strictly accurate but I tried to maintain as normal a driving style as I could and not go mileage-mode for EV drive and I think 250-260kms is the best I can do.

The 320-330 kms it shows at 100 % charge is wildly optimistic and makes one believe you can go the distance, whereas by the time the battery comes down to 50% charge the DTE shows 125 kms and is not the 160-170 kms you expect and you have covered 120-130 kms.

Anyway, it’s still very early and I will try to update if I can eke out better figures, but I don’t see this car going 300 kms if you adopt a normal driving style like ICE.
