Hyundai Ioniq Plug-In range, MPG, CO2 & charging

Officially, the Hyundai Ioniq Plug-in will cover an astounding distance per gallon. Just make sure you keep the batteries charged

The Hyundai Ioniq Plug-in Hybrid is fitted with a relatively small battery for an electric range of only 26 miles. However, the electric motor is boosted by a 1.6-litre petrol engine. Together, they help the Ioniq return astonishing fuel economy and ultra-low CO2 emissions, at least on paper. Nevertheless, the Toyota Prius Plug-In does even better.

Hyundai Ioniq Plug-In range, MPG & CO2 emissions

Officially, the Plug-In will return 248mpg, emits 26g/km of CO2 and will cover more than 600 miles per tank. However, to achieve those figures you’ll need to charge the battery every night and have a very light right foot – or keep the car in ‘EV’ mode, which prevents the petrol engine starting for up to 26 miles.

We’re not saying you’ll never get more than 200mpg out of it, but unless your commute is short and covers flat ground, you’ll be hard-pressed to do so; testing the (non-plug-in) Ioniq Hybrid, we could get only 47.9mpg, which isn’t bad for a regular petrol family car, but is nearly 10mpg worse than a Toyota Prius we also tested.

Charge time

Charge your Hyundai Ioniq Plug-In using a conventional three-pin socket and it’ll take up to six hours to replenish the relatively small 8.9kWh battery. Use a 7kWh wallbox and the charge time comes down to a little over two hours. The Ioniq uses a seven-pin Type 2 charger connection. As standard, the Plug-In Hybrid comes with an in-cable control box (ICCB) emergency three-pin connector cable for home charging.
