Electric vehicles have made massive progress in recent years, and range anxiety is no longer the barrier it once was. In 2025, some electric cars can travel over 500 miles (800+ km) on a single charge, making EVs suitable for long highway journeys as well as daily use.
The Lucid Air Grand Touring currently leads the global market with 512 miles of EPA-rated range (824 km), exceeding the official figures of cars like the Tesla Model S and Mercedes-Benz EQS. In India, models such as the Tata Curvv EV claim up to 585 km ARAI, while delivering around 450 km in real highway conditions.
However, real-world range is often 25–40% lower due to factors such as Indian summer heat (45°C), continuous air-conditioning use, sustained highway speeds of 120 km/h, and a full passenger load. This is why vehicle efficiency (km/kWh) often matters more than battery size alone.
At EV Planet Hub, this analysis is based on publicly available independent 70-mph highway tests, ARAI-to-real-world conversions, owner-reported driving data, and total cost of ownership (TCO) comparisons. Actual results may vary depending on driving style and conditions.

Why Some EVs Achieve Much Longer Range
Long range is not achieved by battery size alone. It is the result of multiple engineering factors working together.
1. Aerodynamics
Lower drag significantly reduces energy loss at highway speeds. Vehicles like the Lucid Air and EQS use smooth underbodies, flush door handles, and sloping rooflines to minimize air resistance.
2. Electric Motor Efficiency
High-efficiency motors and silicon-carbide inverters convert more electrical energy into motion, improving real-world range.
3. Battery Management Systems
Advanced thermal control and predictive energy management help maintain consistent performance even in extreme temperatures.
4. Vehicle Weight
Lightweight materials such as aluminum improve efficiency without compromising safety.
Solid-State Batteries: What to Expect (2026–2030)
Note: Solid-state battery timelines are based on manufacturer announcements and industry roadmaps. Commercial availability and pricing may vary.
| Generation | Battery Type | Energy Density | Expected Real Range | Charging Time |
|---|---|---|---|---|
| 2025 | Current Li-ion (LFP/NMC) | ~250 Wh/kg | ~450 km | ~30 min (80%) |
| 2027–28 | Early Solid-State | ~400 Wh/kg | ~650 km | ~20 min |
| 2030+ | Advanced Solid-State | 500+ Wh/kg | ~900 km | ~15 min |
Indian manufacturers are expected to adopt this technology gradually, potentially offering 700+ km real-world range EVs later in the decade.
5-Year Ownership Cost: Range vs Value
Longer range does not always mean lower cost of ownership.
| Model | Real Range | Purchase Price (₹ lakh) | 5-Year TCO (₹ lakh) | Cost per km (₹) |
|---|---|---|---|---|
| Lucid Air GT | ~780 km | ~95 | ~105 | ~2.1 |
| Tesla Model S | ~600 km | ~75 | ~82 | ~2.2 |
| Tata Curvv EV | ~450 km | ~22 | ~27 | ~1.2 |
| Tata Nexon EV | ~350 km | ~18 | ~22 | ~1.1 |
Conclusion:
High efficiency and widespread service networks make Indian EVs significantly more cost-effective for most buyers.

Real-World Range Tips to Maximize EV Mileage in India
Getting the maximum real-world range from an electric vehicle in India requires a combination of smart driving habits, proper maintenance, and awareness of local conditions. While official ARAI figures provide a benchmark, real mileage can be improved significantly with a few practical steps.
First, maintaining steady highway speeds is crucial. Driving at 90–100 km/h instead of 120 km/h can improve range by up to 15–20%, especially on long expressway runs. Sudden acceleration and hard braking consume more energy, so smooth throttle inputs help preserve battery charge.
Second, air-conditioning usage plays a major role in Indian summers. Setting the AC temperature to 24–26°C instead of the lowest setting can reduce energy consumption without sacrificing comfort. Using ventilated seats and sunshades also lowers cabin heat load, helping the battery last longer.
Third, tyre pressure should be checked regularly. Under-inflated tyres increase rolling resistance, which directly reduces efficiency. Maintaining manufacturer-recommended tyre pressure can deliver up to 8% additional range at no extra cost.
Another key factor is vehicle load. Carrying unnecessary luggage or roof-mounted accessories increases weight and aerodynamic drag. Removing unused items from the boot and avoiding roof carriers on daily drives can noticeably improve efficiency.
Finally, planned charging habits make a difference. Charging the battery to 80–90% for daily use and avoiding frequent deep discharges helps maintain long-term battery health, ensuring consistent range over years of ownership. Together, these habits allow Indian EV owners to extract the best possible real-world range from their vehicles.
Common Myths About Long-Range Electric Vehicles
Despite growing adoption, several myths about long-range electric vehicles continue to influence buying decisions. Understanding the reality behind these misconceptions helps buyers make informed choices.
One common myth is that bigger batteries always mean better real-world range. In reality, efficiency, aerodynamics, and vehicle weight often have a greater impact than battery size alone. A lighter, more aerodynamic EV with a smaller battery can outperform a heavier vehicle with a larger battery in highway conditions.
Another misconception is that long-range EVs eliminate the need for charging planning. While higher range reduces charging frequency, long highway trips still require awareness of fast-charging locations and charging speeds. Charging infrastructure and charging power matter as much as battery capacity.
Many people also believe that EV range drops drastically in all conditions. While extreme heat or high-speed driving can reduce range, careful driving and moderate speeds can keep real-world performance close to official estimates.
There is also a myth that long-range EVs are only for luxury buyers. In India, models like the Tata Curvv EV and Tata Nexon EV demonstrate that usable long-range performance can be achieved at affordable price points.
Finally, some assume that daily users need 500+ km range. For most Indian drivers, a real-world range of 300–450 km combined with overnight home charging is more than sufficient. Long-range EVs are most beneficial for frequent intercity travel, not daily commuting.
