Average kWh per 100 km Electric Car Chart

Introduction

Average kWh per 100 km Electric Car Chart or want to understand how efficiently your EV consumes energy, one of the most crucial metrics is kWh per 100 km.
Similar to fuel economy (litres per 100 km) for gasoline cars, kWh/100 km tells you how much electricity an EV needs to travel a certain distance.

The lower the number, the more efficient the vehicle.
In 2025, with Canada and the rest of the world pushing toward greener transportation, understanding this metric is essential for:

• Reducing charging costs

• Choosing the right EV for long travel

• Planning road trips efficiently

• Evaluating battery performance

• Comparing EV brands and models

This in-depth guide includes a complete efficiency chart, tables, images, and real-world analysis to help EV buyers and owners make informed decisions.

What Is kWh per 100 km in an Electric Car?

kWh per 100 km measures how much electrical energy (in kilowatt-hours) an EV uses to travel 100 km.

Why It Matters

• Helps estimate charging cost per trip

• Shows vehicle efficiency

• Helps compare EVs fairly across brands

• Influences your EV’s real-world driving range

Formula

Example:
If an EV uses 18 kWh to drive 100 km, its efficiency rating is 18 kWh/100 km — very efficient by today’s standards.

Factors That Affect kWh/100 km

EV efficiency is influenced by several real-world variables.

1. Vehicle Weight

Heavier EVs consume more energy.

2. Driving Speed

Faster speeds = more aerodynamic drag = higher consumption.

3. Weather Conditions

Cold weather in Canada increases energy usage for:

• Cabin heating

• Battery heating

• Reduced battery chemistry efficiency

4. Terrain & Elevation

Hill climbing requires more power.

5. Tyre Size & Type

Wider tyres = more rolling resistance.

6. Battery Health

Older batteries may show slightly increased consumption.

Below is a general chart showing efficiency categories for modern EVs.

Real-World kWh per 100 km for Popular Electric Cars (Updated 2025)

The table below includes real-world data compiled from driver reports, EPA values, WLTP standards, and Canadian weather adjustments.

Why Some EVs Consume More Energy Than Others

1. Aerodynamics

Sedans like the Hyundai Ioniq 6 outperform SUVs because they cut through air more efficiently.

2. Drivetrain

RWD models typically consume less power than AWD versions.

3. Battery Size

Larger batteries add weight, increasing consumption.

4. Tyres

Performance tyres increase rolling resistance.

5. Vehicle Purpose

High-performance EVs like the Hummer EV prioritize power over efficiency.

Cost of Driving Based on kWh/100 km

Knowing your EV’s consumption lets you calculate driving costs.

Formula for Cost per 100 km

Example:
If your EV uses 16 kWh/100 km and your rate is $0.15 per kWh:

Cost per 100 km = 16 × 0.15 = $2.40

That’s significantly cheaper than gasoline.

EV Cost per 100 km in Canada (By Consumption Level)

Even the least efficient EVs remain cheaper to operate than gasoline cars.

How Weather in Canada Impacts kWh/100 km

Canada’s climate significantly affects EV efficiency.

Cold Weather (−5°C to −25°C)

• Increases consumption by 25–45%

• Cabin heating uses high energy

• Battery must be kept warm

Hot Weather (30°C+)

• AC usage adds 5–12% consumption

Snowy/Slushy Roads

• More rolling resistance

• Range drops significantly

How Driving Style Influences EV Efficiency

Aggressive Acceleration

Uses more current → higher consumption.

Highway Speed

Driving at 120 km/h vs 100 km/h can increase consumption by 10–20%.

Smooth Driving = Best Efficiency

EVs perform best when you:

• Maintain steady speed

• Use regen braking

• Avoid fast charging unless needed

How to Reduce Your EV’s kWh/100 km

To improve efficiency and lower costs:

✔ Maintain tyres at correct pressure

✔ Reduce excess weight

✔ Use eco-mode when possible

✔ Preheat car while plugged in

✔ Use seat warmers instead of cabin heating

✔ Drive at moderate speeds

✔ Keep windows closed at high speeds

These practices can reduce consumption by 5–20%.

How Much Impact Each Action Has on Efficiency

Electric Car Efficiency vs Gasoline Car Fuel Economy

An EV that consumes 16 kWh/100 km is equivalent to a gasoline car using:

So:

This shows how incredibly efficient electric cars truly are.

Efficiency Comparison: Top 2025 EVs vs Top Gas Cars

Most gas cars average 6–10 L/100 km, making EVs significantly more efficient.

Future Trends in EV Efficiency (2026–2030)

EVs are getting more efficient every year due to:

🔹 Better aerodynamics (drag coefficients as low as 0.18)

🔹 More advanced motors

🔹 Improved battery chemistry

🔹 Heat pump systems

🔹 Lightweight materials

By 2030, expect:

• Average efficiency to drop to 11–14 kWh/100 km

• Compact EVs below 10 kWh/100 km

• Large SUVs under 20 kWh/100 km

Conclusion

Understanding average kWh per 100 km is one of the most powerful ways to evaluate an electric car.
Whether you’re comparing models, planning long trips, or estimating charging costs, this metric tells you everything about an EV’s real-world energy efficiency.

This comprehensive guide — complete with charts, tables, and real-world data — gives you all the information you need to make smart, confident decisions as an EV owner or buyer.
