IDC-to-real-world range calculator

Translate an Indian IDC or MIDC certified range into what a trip is more likely to deliver once speed, weather, air-conditioning, load, hills, and tyres are included.

This is a planning estimate, not a certified range test. Vehicle efficiency, battery age, wind, and driving style sit outside this form. Keep a charging reserve on any real journey.

Certified figure

Certified range IDC or MIDC / ARAI brochure range in kilometres.

How you will drive

City / highway / mixed use Lab cycles are gentle and urban-biased. Highway cruising usually costs more. Average speed Trip-average speed in km/h, including slower stretches.

Conditions

Temperature Outside air temperature in °C. Heat and cold both cost energy versus a 23 °C lab. Air-conditioning use IDC tests run without AC. Cabin cooling is a larger share of energy at low speed.

Payload People plus cargo in kg. Certification is close to a driver-only load. Terrain Regen recovers some downhill energy, not all of the climb.

Tyre pressure condition Soft tyres raise rolling resistance and can also increase cabin and motor load.

What this means on the road

The model will explain the gap versus the certified figure once you estimate.

How the estimate is built

Certified IDC/MIDC range is scaled for use mix, speed (rolling, aero, and accessory load), temperature, air-conditioning, extra payload, terrain, and tyre pressure. Trip-planning range keeps a reserve below the conservative figure.
