400KM Range UNLOCKED! 🚀 Can the 2026 Tata Punch EV 40kWh actually beat its ARAI range on highway?

Can a Tata Punch.ev actually hit its 400km+ range claim in the real world? In this video, I take you through a midnight efficiency run from Ambur to Chennai (Guduvancheri) that shattered my previous records. Driving the 2026 Tata Punch.ev (Supernova Copper), I managed a staggering 97 Wh/km on the dashboard—but as we’ll see from the live OBD2 data, the "Real" story is even better.

🛠️ The Strategy: "Drive Bar 1" & Live Monitoring
The secret to this run wasn't just driving slow (I cruised at 75-85 kmph); it was about Power Management.

Live HV Power Monitoring: I mirrored my OBD2 data to the infotainment screen.

The 10kW Rule: I kept my power draw strictly under 10kW (staying within the first bar of the power meter).

Sailing: Leveraging ECO mode and Regen 0 to maintain momentum on the highway.

📊 The "Voltman" Audit (Trip Data):
Distance: 190.3 km

Route: Ambur ➡ Shriram Shankari Apartments

Starting SoC: 70%

Ending SoC: 24% (Dashboard) | 29.2% (OBD2 Raw SoC)

Dashboard AEC: 97 Wh/km

True Calculated AEC: ~91-94 Wh/km

Projected 100% Range: 413 Kilometers! ✅

🌡️ Conditions:
Ambient Temp: 28°C (Night Run)

Cabin Temp: 24.5°C (AC ON)

Payload: Single Driver + Gear

Time: 10:40 PM to 01:50 AM

💰 The Savings Factor:
This trip cost me ₹0 thanks to office charging. A comparable petrol car at 18 kmpl would have cost me over ₹1,070 for this single leg.

Why the Dashboard says 24% when the battery actually has 29% left.

If you’re a Punch.ev owner or planning to buy one, this is the efficiency standard you should aim for!
