Lexus LS 500h MPG & CO2 emissions

The claimed fuel economy of the LS 500h beats that of non-hybrid rivals, but electric driving range is limited

MPG (combined) MPG (high) MPG (low) CO2 emissions
31-36mpg 36-42mpg 23-28mpg 176-209g/km

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

The rear-wheel-drive version is claimed to achieve 36mpg, with CO2 emissions of 176g/km. The heavier four-wheel-drive version emits 209g/km of CO2 and officially returns 31mpg, although real-world economy 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 is not a car that you buy for its efficiency (despite the hybrid powertrain), so much as for its luxury, refinement and style.
