TrueDelta Reviews the Real Gas Mileage of the Lexus LS

Lexus LS Real Gas Mileage: Cons
YearComment
Nearly everyone except Toyota has been transitioning to boosted engines for fuel efficiency at least as much as for performance. While boosted engines swill gas at least as well as their unboosted equivalents when hustled, in typical driving they are more efficient. With EPA ratings of 16 mpg city, 23 mpg highway, the LS 460 nearly matches the Jaguar XJ AWD (16/24), but falls well short of the Audi A8 3.0T (18/28) and BMW 740Li xDrive (19/28). In the real world, the Lexus's fuel economy lags the others, including the Jaguar, to an even greater degree. In our suburban driving the LS 460's trip computer often reported averages between 15 and 16, vs. low 20s in the Jaguar. A light foot could nudge the LS's average to 18, but the XJ's to 25. On the highway the LS 460's trip computer reported averages of 24.7 and 23.3. The XJ's reported just over 30. see full Lexus LS review
