Thats close to what it takes to run power steering or a thermal clutch radaitor fan when its "free wheeling".
That isobaric part of the otto cycle really sucks.

Well the 1.8 horsepower lost to the vacuum is partially recovered on compression, and probably helps fuel atomization slightly at low engine speed, but yea even if it's 1 horsepower lost that's more than all the accessories minus AC. Good thing cooled EGR is making it to more engines now.'
On the bright side though, engine and drivetrain friction is probably eating up something like 3-4hp on the highway, so 1hp isn't all that bad in a way.
