Why does the Avalon (3.5L) get better mileage than the GS300 (3.0L)?

Why does the Avalon (3.5L) get better mileage than the GS300 (3.0L)?
The 3.5 GR (no direct injection) mated with a 5 speed in the Avalon Limited (3600 lbs) gets 22/31 EPA.
The 3.0 GR (direct injection) mated with a 6 speed in the GS300 (3536 lbs) gets 22/30 EPA.
So, the GS300 has a less powerful engine, direct injection, one more gear, and less weight (all of which should give you better mileage), but actually gets slightly lower EPA mileage.
Why is this?

p.s. it is really not heavier - epa estimates were probably done for lighter model

Toyota on its website specifically states the same 22/31 for all four models, including the Touring. Regardless of whether it was done only for the lighter model, the mileage of the Avalon is pretty impressive for the engine size.

Regarding the Avalon vs. GS300 mileage figures, yeah it's the aggressive gearing that makes all the difference.

EPA mileage figures are not always a good indicator of what you will actually get....for many reasons. My actual mileage is usually pretty close to the EPA estimates, but that is not the case with many people.
The most obvious answer on the surface for the mileage difference between these two cars....and it already has been mentioned.......is gearing. One other factor may play an important role in the real-life (not EPA ) mileage here....the Avalon is usually, though not always, bought and driven by an older, more conservative group of drivers and is rarely if ever used in high-performance driving like some GS's are. The Avalon's tires, on average, also have slightly less grip than the GS's (which is generally designed for sportier driving). Less grip usually means less rolling friction and less work for the engine.....hence better mileage.
Last, there COULD be ( I'm not sure about this ) a difference in Toyota and Lexus A/C compressors. No other car on the road ( not even Toyota ) has ice-cold continuous A/C like Lexus does...I suspect that Lexus A/C units may draw more engine power than Toyotas.

My bad. Your right. Misread the specs.

Because toyota always bull****ted their hp levels sligtly on the optomistic levels. And with the new rating system they cant do this no more! There are exceptions like the Supra TT for example though.
A classic example a 1992 SC400 has 250 hp.. lol right.
Nissan and some honda models does this did this too.. I assure you the 35th edition nissan 350z does not have 300 hp like they say they do for example.
