Theyre totally different cars though. I own a 23 IS and a 23 ES. They’re so different they might as well be different brands entirely. The mostly aluminum suspension of the gen 3.2 IS puts the ES suspension to shame yes even the FS Handling. It’s lighter on its feet yet much more sure footed. Which it should be with all that forged aluminum compared to steel in the ES not to mention different hubs that reduced weight a bit in the gen 3.2 refresh.
seeiously, gondrive a new IS359 back to back against an ES350 of any variety. No comparison and very different.
Regardless the mileage difference is probably mostly due to wheel width and weight, the IS350 FS RWD has wider rear wheels even compared to the ES FS. And much wider and heavier than the non FS ES. That leads to more rotational inertia.
The final drive ratio might also be different which would affect MPG. You’re not looking at the whole picture. And the transmission is definitely different.

I hope the next ES can have a luxury type forged aluminum suspension variation in order to separate it more from the Camry. Every other car in the ES space makes large use of aluminum like 5 Series, A6, E class etc. the achilles heel of the ES has been the Camry. Economies of scale. it would just bump up the ride and handling refinement to segment standards.

I bet that 95% of the drivers of the ES want to have simple suspension and not 14 aluminum arms and bushings like the LS 460 has.
My fifth generation E350 with 145,000 miles has the most simple suspension which even after 17 years feels like new. You can’t have that on cars with aluminum suspension and zillion arms.
