Kia has priced the Sorento well below large SUVs from premium brands such as the Land Rover Discovery and Volvo XC90 – both of which start north of £50,000. At the same time, the South Korean car is considerably more expensive than equivalent seven-seater rivals such as the Skoda Kodiaq or SEAT Tarraco – both of which start at less than £30,000.

In addition to this, the diesel Sorento costs around £1,500 less than the equivalent hybrid. Granted, diesel is more expensive to buy than petrol, but the diesel's slightly better fuel economy should offset this. For company-car drivers though, the lower CO2 emissions of the hybrid versus the diesel will be enticing, while the upcoming plug-in model will make the difference even more clear-cut.

Kia Sorento Hybrid insurance group

The Kia Sorento sits in groups 30, 31 and 32 for insurance – 2 trim is the lowest-rated, then 3 and then 4. Again, the car splits potential competitors. Upmarket rivals such as the Discovery and XC90 start (at best) in the low-to-mid 30s but often surpass group 40 and a few are even in the maximum group 50. More affordable alternatives, such as the Kodiaq and Tarraco, don’t tend to be rated at much more than the early 30s and can drop as low as group 15 for entry-level variants.


Kia has been leading the car industry for warranty cover for quite some time, as all its models come with a seven-year/100,000-mile guarantee, and the latest Sorento is no different. All of the hybrid system's batteries and electronics are covered for the same period.


The service interval for the Kia Sorento Hybrid is every 12 months or 10,000 miles, whichever comes first. To help with maintenance, Kia offers a number of servicing plans, lasting for two, three or five years. The shortest plan costs £435, but adding another year ups this to £699 – the longest plan is priced at £1,229. MOTs can also be added, at a cost of £35 each.

Road tax

When first registered, the Kia Sorento Hybrid faces a £530 road-tax bill (usually rolled in to the 'on-the-road' price), which compares with almost £900 for the non-hybrid version. From the second time it's taxed onwards, owners face a £140 annual bill, which is standard for all hybrids. But any car that costs more than £40,000 (including optionals) is liable for an additional £325 payment the first five times the tax is renewed.

Company-car Benefit-in-Kind (BiK) rates for the Sorento Hybrid aren’t all that impressive – at least until the even more frugal and low-emissions plug-in hybrid version joins the range. For a 20% taxpayer, BiK will be roughly £2,700 a year or £227 a month. Those in the 40% bracket will pay £5,438 each year or £453 per month to run a Sorento.
