Why are they selling 440 hp Mustangs when oil is reaching peak supply?
Because there are people who want to purchase them.
Market sez that some people want 440 HP Mustangs.
I’m not sure what your beef is with the Mustang, in particular. For one thing, Today’s high-horsepower vehicles are considerably more efficient and pollute less than similar vehicles from the '60s-'70s heyday of the muscle car. Secondly, the next-gen base-model Mustang, I believe, will use a turbo four. Lastly, there are far more large pickups, with huge V-8 engines and the aerodynamics of a brick, running around being used as daily commuter vehicles, than there are Mustangs. Personally, I’d get more exercised over that.
Don’t most V-8 powered, fuel-injected, computer-controlled vehicles these days shut off cylinders when they aren’t needed? That big truck you see on the highway may only be running on four cylinders.
Powerful sports cars are basically hobby items; they are recreational and rarely driven daily even. They are going to be around still when oil (or what ever fuel) is much more expensive than it is now. They are a luxury item. I might rent one for fun next time I am travelling.
Commercial vehicles are much more of an issue. My 3/4 ton work van is loaded with tools and sundries and gets a good 25-30000 km put on it a year. The tank is over a hundred litres. Two mustangs can fill up and grab a coffee while I top off the tank. We are looking at what we can do as far as logistics to reduce our overall mileage because fuel is becoming a major expense.
Because not everyone can afford the 700 hp model.
It’s this [new-fangled thing](his must be distinctly understood, or nothing wonderful can come of the story I am going to relate.) that’s been around since the 14th century. You may have heard of it.
In the spirit of fighting ignorance and all, does one of you who know what you’re talking about want to address the OP’s assumption that we’re approaching peak oil?
Because it’s been done to death here.

I was about to. The peak-oil threat dislodged the bogeyman threat at least 35 years ago.
The U.S. exports more oil than Saudi Arabia.
Canada is caught between a rock and hard place. It has so much oil it needs to invent teleportation to get rid of it, but if it invents teleportation no one would want it. So teleportation remains a dream.
I just assumed that he would never be back to read it.
Baloney. I drive my Vette everyday. And before this I drove my Jaguar XK almost every day. I even drove my Mustang GT during the winter.
Bad link. It doesn’t have a URL.
Seems to have something to do with Marley’s ghost
Whoosh!
2014 Mustang with the 5.0 litre engine gets 18 city and 25 highway.
My 2006 Subaru Outback 4 cylinder gets 20 city and 28 highway.
The Mustang isn’t exactly a horrible fuel waster, if you look at it in perspective.
I’m actually considering a used Corvette as a daily driver. Rated at 17city/25 highway.
I guess what we are saying is that we really don’t see what your point is.
Yeah, I guess I was. Can anybody explain it to me? I’m a little extra dense this morning. 
More baloney - there’s no way you’re a car enthusiast yet don’t know that your behavior is not the norm. The typical sports car sees 2500-3500 miles a year because the typical sports car is the owner’s second or third car, not a daily driver.
In the case of something like the Mustang, yes, you’ll find many that are daily drivers - those don’t tend to be the hi-po models or special editions.
Weird; it was a link to the Wiki page about supply and demand.
