[DeTomaso] 4,000 pound Mustang???

Generating horsepower costs mileage regardless of what or how power is made. There is no magic. F-1 and Indy-cars both put out around 600-700 bhp (peak) and struggle to make 3.8 mpg average- one on methanol, one on what F-1 calls 'gasoline'. If you use all the blown Mustang's (or a quad-turbo Bugatti's) power, fuel mileage drops like a rock in direct proportion to how long the gas pedal is matted. If you drive reasonably in real world traffic (using maybe about 200-250 bhp), likely the Mustang with street gearing will be in the mid '20s- like a well tuned Pantera from 50 years ago.
As for the 2 tons of weight, that's a direct result of all the "modern" conveniences and driver-distractions that factories include today on what they call 'performance' machines, in spite of lots of aluminum, carbon fiber, etc. A C-8 with all-aluminum frame & al/balsa-wood floor weighs about what a 'Vette weighed 30 yrs ago but without the motorhome distractions.
My best guess- J DeRyke

I thought that supercharging done right didn't kill mileage. I know
the compression probably has to be lower, but I have been told that
modern superchargers are almost invisible when off boost. There is an
advantage that the cam on a supercharged engine can be milder allowing
more efficiency at low RPM. Maybe that's just true for turbos?
Maybe emissions requirements are part of the equation?

Ken,
A 760 hp supercharged engine has a little to do with the fuel
economy...

The Ford Mustang Shelby GT500 with 760 horsepower faces off
against the
650-hp Chevy Camaro ZL1 1LE.
How did the Mustang get so heavy, and only 18 MPG highway? I
thought
the new engines were efficient? I thought highway mileage was
cruising
at 65 to 70? Is their mileage really that lousy?
