In real life, you are unlikely to get more MPG from any auto because they are less efficient / more losses (much heavier too) than a manual. just physics.
Any kind of 'normal' driving for the sports car it is will put you back in the low MPG brackets.
DCT or Torque converter box can never be more efficient than a manual box, but they are able to fudge the test.
Indeed, I managed to get 13mpg when I tested the Auto
