How efficient is Hyundai Ioniq Electric. Is this the EV efficiency king?

2020 Hyundai Ioniq Electric – The Efficiency King of EVs

This video explores the real-world efficiency of the 2020 Hyundai Ioniq Electric, a compact EV with a 38 kWh battery that is surprisingly capable of delivering over 200 miles of range in normal driving. The creator, who typically drives without focusing on economy, sets out to see how much range he can extract by applying deliberate, efficient driving techniques over a two-hour mixed-road journey.

🔋 Vehicle & Baseline Efficiency

• The Ioniq’s small battery pack (38 kWh) is offset by its lightweight design and aerodynamic shape, making it one of the most efficient EVs on UK roads.
• In everyday driving (no special effort), the car consistently achieves 5.5–6.0 miles per kWh – already impressive compared to larger, heavier EVs.
• The car’s heat pump and efficient climate control system draw minimal power (0.3–0.75 kW), so comfort doesn’t heavily penalise range.

🚗 Driving Techniques for Maximum Efficiency

• Gentle acceleration and deceleration are key – the goal is to avoid using the friction brakes entirely.
• Regenerative braking (adjustable via flappy paddles) allows the motor to slow the car while recovering energy. The creator recommends using the strongest regen level and modulating speed with the accelerator pedal.
• Eco mode dulls throttle response but is not essential; the same economy can be achieved in Normal mode with a light foot.
• Reading the road ahead – lifting off early for junctions, roundabouts, and traffic lights – prevents energy loss and maximises regen.

📊 The Efficiency Test Results

• After 2 hours 19 minutes of driving (64 miles) on mostly 40–50 mph roads, with a short motorway section, the car recorded 7.4 miles per kWh.
• The car’s onboard computer rated 99% of driving as “economical”.
• Extrapolating this consumption over the full 38 kWh battery gives a theoretical total range of 280 miles – far exceeding the official WLTP figure.
• The creator notes that with more focus, 8.0 miles per kWh is achievable, as early parts of the drive showed 8.3–8.4.

🏆 Comparison with Other EVs

• The Ioniq is more efficient than most modern EVs, including the Hyundai Kona, Kia e-Niro, and Tesla Model 3, because it prioritises light weight and aerodynamics over SUV styling and high power.
• Only the Volkswagen e-Up (and its Skoda/Seat siblings) come close in efficiency.
• The Ioniq has been discontinued, and newer EVs are generally less efficient due to larger batteries, heavier bodies, and more powerful motors.

Key Takeaway

The 2020 Hyundai Ioniq Electric demonstrates that efficiency is the true enabler of affordable, practical EVs. With a small battery and careful driving, it can achieve 280 miles of real-world range – a figure that rivals many modern EVs with much larger packs. For daily commuters who can charge at home, this car proves that you don’t need a big battery to go far; you just need an efficient design and a light right foot.
