The Hyundai Ioniq Plug-In is no longer on sale as a new car, but values are strong as a used model. The long warranty and surging demand for plug-in cars means that it’s sought-after by many, and although the PHEV is a bit more expensive to buy than the normal Hybrid, it could be worth it over the long term because of lower running costs.

Hyundai Ioniq Plug-In insurance group

Following a 2019 update, both versions of the Ioniq Plug-In Hybrid fall into insurance group 12. That’s on par with the Toyota Prius Plug-In, but quite a bit lower than pure-electric cars such as the Nissan Leaf, which is in group 21. As such, insurance premiums should be good value for most drivers. Hyundai offers its own insurance policies, which come with a range of benefits, but you can use your own provider if you prefer. As with any insurance policy, you should shop around for the best deal.


The Hyundai Ioniq’s warranty is comprehensive. As standard, the car was covered for five years, with no mileage limit. There’s also a 12-year anti-perforation warranty, plus a separate lithium-ion battery warranty, which protects against capacity loss for eight years or 125,000 miles. This means there are plenty of used models with lots of warranty left.


Service intervals are determined by the Ioniq’s on-board computer, but if you cover an average of 12,000 miles a year, reckon on paying a visit to your local dealer around every 18,000 miles. Hyundai offers a range of service plans to suit your lifestyle – your dealer can discuss these with you.

Road tax

Annual road tax is only free on cars with no CO2 emissions these days. However, Ioniq Plug-In drivers will only pay £145 a year from the second to sixth year of ownership – £10 less than any non-hybrid car.
