Yes - I'm certainly being pedantic. You're correct in that driving style can have a huge impact on fuel consumption. You don't have to hypermile it; just not playing speed racer between red lights, cruising at 70 instead of 85 helps, etc.
I was just kind of blown away by the claim. Not that long ago, high 30's MPG on the highway was the domain of economy cars (think Corolla's and the like) and euro diesel cars. To hear that a gasoline SUV, albeit a smaller one, could be close to 40MPG on the highway made me skeptical and curious of how it was achieved.
