2013 Lexus GS450h Returns 34 MPG Highway, GS350 Up to 28 MPG
When Lexus revealed the 2013 GS450h hybrid, it claimed the new car would boast a fuel-efficiency improvement of more than 30 percent. The EPA figures are in and the GS450h has met those expectations, returning 29 mpg in the city and 34 on the highway. The last-gen GS450h was only good for ratings of 22/25 mpg.
The GS450h’s fuel-stinginess figures compare favorably with those of the upcoming BMW ActiveHybrid 5 and Infiniti M35h. The Infiniti is rated at 27/32 mpg, and we estimate the ActiveHybrid 5 will return numbers similar to the new four-cylinder 528i (23/34 mpg).
The nonhybrid GS350 also sees its efficiency improve slightly. The rear-driver’s efficiency is up 2 mpg on the highway (19/28 mpg) and the all-wheel-drive model sees a 1-mpg increase in both city and freeway running (19/26). The GS350 hits dealer lots in February, with the GS450h following later in the year.
