Lexus NX review - MPG, CO2 and running costs

Lexus has made the NX premium SUV even more appealing by introducing efficient plug-in hybrid technology

While the NX 350h hybrid model starts at around £40,000, you’ll need at least a further £10,000 to secure an entry-level 450h+ plug-in hybrid version. Which option you go for really depends on your individual lifestyle and driving habits; the self-charging hybrid provides decent overall economy at around 44mpg, although with CO2 emissions of around 136-145g/km, it isn’t going to woo any company-car drivers.

Although more expensive to buy, the NX 450h+ PHEV should prove to be cheaper to run. It can cover up to 40 all-electric miles from a single charge of its 18.1 kWh battery, while switching to petrol power still sees fuel economy of more than 40mpg.

With CO2 levels of around 21-25g/km, it will attract a much lower Benefit-in-Kind tax rate than its cheaper sibling. Charging the battery shouldn’t be an issue, either, as topping up using a 7kW home wallbox (from 0-100%) should take just under three hours.

Insurance groups

Insurance premiums for the NX 350h self-charging hybrid model shouldn’t be too expensive for a premium SUV, as the entry-level NX version is in group 32, while the F Sport and Takumi variants are in group 35 and 36 respectively. In comparison, a 261bhp petrol-powered Audi Q5 in popular S line specification sits in group 38.

Moving up to the more powerful (and pricier) 450h+ plug-in hybrid inevitably brings an increase in insurance costs, from group 38 for the base car through to group 40 and 41 if you opt for either the F Sport or Takumi trim levels.

Depreciation 

Lexus models have generally enjoyed solid residual values, and the NX is no exception. Over an average ownership period of three-years and 36,000 miles, the NX is predicted to hold onto around 52 per cent of its original list price. Models specified with the Premium Pack tend to perform slightly better than average at 54 per cent. This compares similarly to the BMW X3 range, and just ahead of the Audi Q5 which sits at around 50 per cent if you decide to sell after 36 months.
