Lexus RX L 450h running costs

Thanks to low CO2 emissions, the Lexus RX L 450h will prove to be attractive for company-car buyers

Insurance group Warranty Service intervals 2018/19 company car cost (20%/40%)
40 Five years / 100,000 miles 12 months / 10,000 miles £2,897.72 / £5,795.44

Claimed fuel economy for the RX L is 47.9mpg when riding on 18-inch wheels, dropping to 41.7mpg for 20-inch alloy wheels.

Thanks to CO2 emissions of 136 to 138g/km, the RX L 450h qualifies for a Benefit-in-Kind (BiK) company-car tax rate of 28% – a lower bracket than many of its diesel rivals. This makes it an attractive proposition for company car drivers.

Lexus RX L 450h insurance group

The SE model falls into insurance group 41, with the Luxury and Premier versions falling into group 43. These groups are lower than for chief rival the Volvo XC90 T8 Twin Engine.

Lexus also offers its own in-house insurance cover, giving you a courtesy car when your vehicle is in for repair and a protected no-claims discount if you’re hit by an uninsured driver.


Unlike their Toyota counterparts, all Lexus vehicles are covered by a standard three-year/60,000-mile warranty, but extended warranties are available for models up to 10 years old or 140,000 miles. The hybrid system and battery in the RX L 450h are covered by a five-year/60,000-mile warranty.


The Lexus RX L 450h requires servicing every 12 months and 10,000 miles. Lexus Service Plans allow you to combine all the servicing costs into monthly payments, with the price based on the length of plan, what’s included and how frequently you’d like to pay.

A Hybrid Health Check is included in all services, with a technician checking the entire system and providing a written report. This also includes a one-year/10,000-mile warranty on the battery.

Road tax

All models of RX L will cost £455 a year to tax the first five times it's due, dropping to £135 a year thereafter.


Lexus expects a third of RX buyers to opt for the L 450h model, and we’d expect this exclusivity to boost residual values. Depreciation will be slowed by the absence of a diesel engine and the extra seats over the standard RX.
