Why the Curvv EV makes more sense than Nexon EV LR for highways

If the plan is to use the car only in cities, get the Nexon EV MR.

Somehow all the mainstream media including team-bhp keep missing out on how important charging speed is and it's barely even mentioned in comparisons.

A real-world example of how a 500 km drive on a highway will play out:

Base assumption: 6 km/kWh at highway speeds with AC

With the above efficiency, an energy consumption of 83.3 kWh will be needed to complete the trip. To give yourself enough buffer, let's round it to 90 kWh.

Nexon LR: 40 kWh will need two charging stops to complete this journey

• Stop 1: At 10-20% SoC with buffer to spare. Charge up to 90%. This should add 28 kWh and given that the DC charging speed is capped at 30 kWh, will take around 1 hour.
• Stop 2: We need another 22 kWh to complete the journey. So at any SoC below 40, we will need to stop for our second charging session. Assuming we plug in at 30%, adding 22 kWh should take around 45 mins.

Curvv 55 kWh: We will need to add 35 kWh to complete our journey i.e just one-stop

• Stop 1: At 25% SoC, charge up to 90%. This will add 36 kWh. With a 60 kW charger which is the most common on our highways, this will take ~45 mins.

Time savings vs Nexon LR: 1 hour, coupled with a meal/rest stop, your travel time should be the same as an ICE vehicle.

Significant cost savings as well because your dependence on DC charging infra is lower now.

Also, do note each charging session also has overheads in terms of finding the charging location, plugging in etc.

The decision is simple, if you want to undertake long drives on your EV and you have to get a Tata EV, please buy the Curvv. If the plan is to use the car only in cities, get the Nexon MR. The LR model will cause you a lot of pain during long drives
