Theoretically, the NX 300h can return 54.3mpg (or 56.5mpg for the front-drive S) on the 'combined cycle', which, thanks to a large amount of time at low speeds, favours cars that have some ability to run on electricity alone. Hence, starting a journey with a fully charged battery and maximising use of the EV mode over a short distance it's possible to return over 40mpg, but even that looks optimistic once you spend any deal of time on the motorway or fast A-roads.
The petrol-only 200t isn't any better. Officially it returns 35.8mpg, but achieving that is the work of featherweight footwork and plenty of luck. It slots into VED band I with emissions of 183g/km, costing £225 a year to tax and putting it far out of reach of company car buyers. That, however, is where the NX 300h comes in.

Emissions from the S are just 116g/km and even the F Sport model emits no more than 121g/km so those with an eye on their BIK tax bill should take a closer look.
Lexus offers fixed-price servicing, which comes in at £245 for an intermediate service or £445 for a full service in any NX. The standard Lexus warranty of three years/60,000 miles is augmented in the 300h with two extra years' cover for the hybrid components, including the battery.
