Ok, to respond to all at once, first, to the Multi-Displacement V8s. It's still a V8, it is still reciprocating against friction, vacuum, consuming energy to increase economy, sorry it can be done better than that. It'd be the arguement of saying I only need one lung, I have two, but need one, are you as efficient with one as you are with two at half the capacity? No of course not, neither is an engine that's alternatively firing cylinders to reduce consumption, the first generation MD Hemi actually got pretty bad mileage.

And to "motogp34" First, to tune the car cost $656.88, I bought the HP tuners cable and program so I could at least have a look at the tables and make minor adjustments, the price also includes the availability of proven tunes for certain amounts of power, all available for download, it even includes the ability to "live" tune the car via datalogging and uploading to HPtuners so their staff can custom tune your car remotely. A mobile mustang dyno at Capitol Raceway outside of Baton Rouge logged just over 300WHP and 313 lb-ft TQ. At this very same track I had an enjoyable weekend, which is where an almost factory 2006 Mustang GT got his butt handed to him. He had the intake, the exhaust, maybe a programmer, I doubt anything else, and he was on street tires.

As I said initially before an obvious attempt at trolling, this car is DUAL purpose.

Things I have done so far include removal of the trunk interior, removal of unnecessary plastics, the spare tire and jack, An HPTuners custom tune with a lean cruise feature. Muffler delete, which was the heaviest thing thus far on the car, at least 50 lbs. I have also added corrugated plastic sheeting, black in color via aluminum rivets to the dead space behind the air damn in front of the tires, while cutting a small directional vent towards the inside of the brakes. I have also added the same material while avoiding the exhaust to everything behind the rear axle. I had also tried wing removal, it turns out I actually LOST .9 mpg on two tanks in the same general conditions with it removed, has since been reinstalled. I also run 43 psi front, 46 rear. I fixed the rear brake problem most SS/TCs seem to have which is nothing more than a lack of lubrication when it was factory installed, that alone gave back .5mpg. The presence of a boost/vacuum gauge gives me a great tool to measure my driving, this is probably the best thing for me in the eco-sport quest.

And yea, I've embarrassed many cars on the track, I don't need to list, but the Mustang is on it, the Camaro SS is on it, the charger SRT8, challenger SRT8, v8 s10, 8100 Vortec Silverado, Several Hondas, including the newer K20 Civic, and an unknown year Eclipse GST, who by chance is also an ecomodder, and he is on this forum...i wish I could remember his screen name, I don't believe the eclipse is on his eco car list though, I've looked for eclipses.

In any case, the car has more than 15K miles on it, I've had no problems with it other than the brakes which was an easy fix, and the shift linkage, which was a warranty fix. I haven't yet broken my 40mpg goal, but I hope I can.

And one last thing, show me a Mustang "faster" than this car, from the factory that can match it's efficiency, or at least come near it's efficiency. OR better yet, HP for HP, find another 300HP car that can break 30mpg. Or at least Chevy's 260SAE BHP and the epa rated 30. The point is I bought it because it is quick, it is nimble, it's efficient and not as expensive as having two cars for two different purposes.
