Political reasons aside;

-More complicated and expensive emissions system, mainly because relatively new technology.
-Stronger and more expensive engine components, to deal with the much greater compression ratios and torque.
-Stronger and more expensive drivetrain to deal with with the much greater torque.

That's enough to be $2-10k more
