Reasons the new Ford GT is the way it is:
1. V6? WTF!
Reason:
ACO (Le Mans) and IMSA (Tudor United Sportscar Championship) regulations state engine size for GTLM (class the new GT would compete in) must be no larger than 4.0L. Ford does not make any small displacement V8 and a V6 is a far better option (size, weight, efficiency, etc) for competitive racing. While it is possible to apply for an exemption to this rule, smaller engines are the way of the future for road and race cars alike.
In addition, Ford did not build this car just so it can look all pretty in somebody's garage... no... this car is going racing and was built with that purpose in mind. And that is exactly what the Ford GT has ALWAYS been about.
Finally, and begrudging to most (myself included if I am to be honest), this is a marketing decision. Ford has to sell EcoBoost to the masses and this is the most logical way to do it. With that said, I would have loved to seen a boosted version of the GT350 engine.
2. Paddle shifters
Reason:
This is a little more questionable in my book but the reasoning is simple. This car is supposed to be world beating. The standard of the world is paddle shift DCTs. Also, the tech in this car will likely be quite advanced (Ford or not) that putting a manual in this car would likely hinder it's potential performance. With that said, I will not be pleased when the Mustang goes paddle only.
3. Kinda crazy looks (lots of big gaps and vents and such)
Reason:
Again, because race car. It is not a coincidence the GT looks the way it does. The entire rear section is meant to do 2 things, create downforce (negative lift... IE the opposite of a plane) and draw air away from the engine.
Compare to a Le Mans Prototype 1 car (Toyota TS040):
