The Lexus LS 500h is available with rear or four-wheel-drive. The entry-level LS is rear-drive only, the Premium Pack can be had with either, the F-Sport is rear-drive only and the Takumi is four-wheel-drive only. This choice has a bearing on the car's fuel economy and CO2 emissions numbers.

Lexus LS 500h MPG & CO2

The rear-wheel-drive version of the LS is claimed to achieve 36-37mpg fuel economy, with CO2 emissions of 182g/km in entry-level form or 184g/k as a Premium Pack or F Sport. The heavier four-wheel-drive version emits 214g/km of CO2 in Premium Pack spec and 215g/km in Takumi guise, while official fuel economy here is just 31mpg, although real-world economy in mixed driving is quite likely to be in the 20s.

Those figures make the Lexus LS 500h one of the least fuel-efficient executive cars you can buy, but they are still better than petrol-powered rivals with similar performance. Even so, this isn't a car that you buy for its efficiency (despite the hybrid powertrain), so much as for its luxury, refinement and style.
