I just completed a 1200 mile journey across California. The consumption is coming out to be around 27 mpg and these were primarily highway miles.
Is this MPG common other 328GT drivers?

OP, I had an F30 328 xdrive non sport rental recently and I got a ~35 mpg highway going 70 mph with speed control and around 25-27mpg in 50/50 driving
Cruising speed and using speed control make a big difference, as does how gently you accelerate from a stop.
My GUESS is your are cruising at a faster speed and using a lot of throttle when accelerating. If you are into the boost, the mpg takes a big drop. Also, with the GT bodystyle and xdrive your car has the weight of a small crossover SUV, so if you compare with SUV and not RWD 328i you are doing great.
