25MY WRX gets 33mpg hwy

Just completed almost 1,000 miles traveling from Miami FL to the middle of TN. The WRX manual achieved a whopping 33mpg on the hwy with 4 people in the car and the trunk full of luggage. I kept it at cruising speed 70-72 mph. But I wasn’t expecting such great mileage AT ALL. At one point it was doing 34.7 mpg! Very happy with this car.
In comparison, our 23MY Outback 2.5L only got around 28mpg.
