Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 44 - 44 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Although it’s not a cheap car, it turns out the Lexus RX running costs aren’t ruinous. Road tax rates are as low as many small family cars and so is fuel consumption if you spend much of your time on the road in town. Servicing at Lexus centres won’t be cheap though and Lexus doesn’t offer a fixed price servicing option when ordering the car – something that’s available from BMW.

For company car drivers, tax liability is roughly half as much as for its main diesel rivals.

Lexus RX emissions are one of the car’s party pieces. The RX450h is greener than many family cars let alone rival 4x4s. With CO2 emissions of 145g/km, the RX is significantly greener than most diesel-fuelled large SUVs.

The Lexus RX reliability record shouldn’t cause much concern. Lexus vehicles are among the most reliable you can buy so there are no real concerns on this front. Hybrid parts are guaranteed for longer than other items under warranty.
