It's a crock. Car and Driver averaged SIXTEEN MPG in their test SHO. Not 16 city/20-something higway. AVERAGE of sixteen. That's worse than my Q, which I drive as if stolen.
There were a couple recent threads in general chat (one about forced induction, the other about the SHO itself) where I've talked about the stupidity of using turbos on small motors to equal a big motor. V8 has more torque all around, can get away with taller gearing (though, again, I get better than 16mpg average...WITH my 4.08) and can cruise at much lower rpm than a boosted 6. I have never been a FI kind of person...FI is what you do when you're out of "real" options. Subtracting displacement and then adding cylinders just to barely break even seems like running in circles to me.
It really annoys me that so many manufacturers are using turbos as fuel economy tools when in reality they are nothing of the sort. If you're making more power, you're using more fuel. It's that simple. If you're stuffing more air into the cylinder (whether via larger cylinder volume or compressors) you're going to have to add more fuel, too. Why not just go the simple, reliable, broad-purpose route and make a BIG motor that can cruise at 2000rpm on the highway and doesn't need to rev past 3000 in town?
Of course, part of the new SHO's problem is it needs a diet. And I'm not talking about size, I'm talking about unnecessary garbage. The car is AWD but the AWD system is so downtoned and low-tech that the only time it ever comes into play is in bad weather. It's not a handling enhancer and is basically just FWD until the front wheels need more traction. But it adds tons of weight and complexity...the end result of which is a curb weight of 4300lb with no worthwhile benefits.
