Lexus ES 300h MPG

The combination of petrol power and electric motor assistance work to good effect in the new Lexus, with the promise of an average 53mpg return from every gallon of unleaded. Toyota and Lexus have both decided to rid their line-ups of diesel engines, but in the case of the Lexus ES, that’s clearly no hardship.

The secret of the ES’ success lies partly in the development of the more efficient combustion technology for petrol engines that Lexus has used since 2005. In fact, the company claims its 2.5-litre engine is one of the most thermally efficient engines in a production car – resulting in more power without increasing emissions or fuel consumption.

CO2 emissions

The Lexus ES has a very creditable CO2 rating of 100-103g/km, which is competitive with diesel-powered rival exec models. For instance, the BMW 520d has emissions no better than 119g/km, while the Mercedes E 220 d comes in at 122g/km.
