2014 370z Sport only 11 mpg

i would try driving on hwy at 50-55mph constant for 10-20miles to see how the mpg is affected. if it still doesnt improve i would say take your car to the dealer.

chances are, you're a tad heavy foot and just enjoying your new car while the car is breaking in.

I was driving like an old lady for the first 1200 miles, I thought only the first 1200 miles are the break in period? BTW, the computer says the average speed is like 16 mph, too slow?

1200 miles is the break in period, but the motor will continue to break in for some time. 16 mph average is very low. If all you do is drive in traffic, mpg will be low. Give it a few more tanks and keep track. It'll get better.
