The Hyundai Ioniq Plug-in Hybrid is fitted with a relatively small battery for an electric range of only 39 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 257mpg, emits 26g/km of CO2 and will cover more than 660 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 39 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. Figures have yet to be released for a public 50kWh charge point. 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.

Battery warranty

Hyundai’s battery warranty for the Ioniq Plug-In Hybrid is one of the best you’ll find. The lithium-ion polymer battery is guaranteed for eight years or 125,000 miles, whichever comes first.

Battery lease

Hyundai doesn’t currently offer a battery lease scheme, because the battery is bought with the Ioniq.
