It is quite a vehicle. I would bet the 21 mpg city is real life possible,and I know folks who get an honest 23mpg hy with 5.3 Suburbans,so I would bet the 22 mpg can be bettered-maybe 25 mpg at 60 mph on level ground.Older Suburbans(1998 2wd 200,000 miles- worn tires-42 psi) can get 19+ mpg on short city trips, if you shut the motor off at redlights.Without cutting the motor 14.5 mpg is about it-even when driven carefully-P&G etc.This is with a warm motor of course.
The H Yukon is a niche vehicle.I think GM has decided all the huge SUVs will be niche vehicles, not volume sellers.This might be behind the announced increase in prices.Seems crazy for a corp that is losing market share to raise prices, but I bet they raise them on Suburbans/Tahoes/Yukons etc.Once they clean out current inventories,they will build fewer, but sell them for more.The $55000 they want for the Hybrid Yukon clearly makes it a niche vehicle.No middle income need apply.Folks of average means won't be buying a "normal" Tahoe as their primary vehicle-not with $140 fillups.
Very nice vehicle, but not for me-not for $60000 OTD.
